March 2009: Tree Specialist Needed for fig and persimmon

Looking for a tree specialist who is familiar with fig and persimmon trees who can take a look and give us a course of care. We have one of each in our North Berkeley back yard - both were full of fruit when we moved in last summer, but almost all the persimmons quickly fell off the tree except for a couple which survived and were quite tasty when ripe; the green figs seemed to do quite well, but when ripe, the fruit was actually pretty dry inside. Bill


Bill, If you are getting massive fruit drop from the persimmon tree, you may not be watering it regularly enough, or deeply enough. If the figs are dry inside, sounds like water again. If you know you are giving the trees adequate water, and think a pest might be producing these results, I would call Sally Jo Dinwoodie at 510-527-5916. She's very good at identifying problems in plants and can recommend non-chemical methods for dealing with them. If you think the trees need pruning or shaping, call arborist Christopher Bowen, 925-377-7853. Both people are reasonably priced and very good at what they do.
I've used a guy named Brad Cazden for fruit tree maintenance who is really great. He specializes in trees and will help you develop a plan for on-going maintenance, which you can do or he can come back and do for you. He's a very nice, thoughtful, hard working guy. You can reach him at: bradcazden@gmail.com

Feb 2009: Tree trimming, evaluation, possible removal

Hello, Can you recommend a company, or individual, who can do some tree trimming, and also evaluate a large tree for its health / possible removal? Person/company should be honest, reliable, careful, and willing to remove all the ''trimmings''. Know anyone who can help us out? We're in Berkeley. Trees need some care


We have been very happy with Peter Rudy. We got his name from BPN and have used him for several large and small jobs recently. He is knowledgeable, responsive and reasonably priced. His company is Big Chief Tree Service, 510-528-3588. He can be a little hard to get hold of, so be persistent. ckatz
We have always loved the work of Complete Tree Care. Matt comes out to do the evaluations and usually his crew does the work. Communication has always been good and unlike other trimmers, they take just the right amount off; I have had too little and too much by others...they are always just right. And yes, they do great cleanup. Complete Tree Care (510) 883-1748 See my yelp review here: http://www.yelp.com/biz/complete-tree-care-berkeley DeAnna
I was very happy with the tree removal performed by Michael Veneziano of Ponderosa Tree Service. He is a certified arborist so I'm sure he can assess the health of your trees. He removed a HUGE Monterey pine planted too close to two homes. He and his crew did an amazing job getting the tree out of a tight spot, and they did an impeccable job cleaning up all the debris. I would hire him again. Vicki
Joe Lamb of Brende & Lamb is extremely knowledgeable and trustworthy. He and his crew took out a tree at my former apartment that was diseased and his crew has trimmed the large cedar at my house on several occasions, each time deftly balancing my daughter's need for a good climbing tree and the family's need for more light in the living room. When we first moved in to our house I considered removing the tree but didn't want to lose the privacy. Joe figured out a way to maximize the privacy and the light and support the tree's aesthetics (this particular tree needed a lot of help!). On their website (www.brendelamb.com) there's a link to an article published in the SF Chronicle on Joe-- tells of how his love for and interest in trees extends all the way to the rain forests of Borneo. I whole-heartedly recommend Joe the Arborist! Carrie
I would enthusiastically recommend Matt Horn of Matt Horn Landscaping and Tree Care. Matt evaluated and pruned two very large trees (a pine and a redwood) during a comprehensive landscaping job he did for us. He was very knowledgable, and worked with the goal of maintaining the beauty and health of our trees. Matt was very reliable and cleaned up the site thoroughly, and his bid was very reasonable compared to several others that we got. Matt can be reached at 658-6088. Feel free to contact me as a reference. Lucy
Matt Horn Landscaping and Tree Care, has done a great job taking care of all the trees i have encountered in the course of my landscaping work. We have collaborated for over a decade, and he has done assessments,seasonal fruit tree pruning, as well as large aesthetic pruning jobs and removals. He has an Arborist's license, liability insurance, and worker's comp insurance for his great crew. You can contact him at 510 658-6088 or email him at matthornlandscaping@mac.com Michelle B.
Jan 2009: Patient arborist who knows a lot about fruit trees

We have just moved into a place with a lot of old (25 years +) fruit trees, many of which we can't identify. Apparently a previous owner was an avid planter and grafter and there are all sorts of varieties of fruit trees and ''fruit salad'' trees in the yard that the person we bought from couldn't identify.

Can someone recommend a patient arborist who specializes in fruit trees and who could walk me and my husband through our yard and identify trees and explain how to prune and maintain them? It would be great to find someone who's willing and happy to talk through the process with us rather than just write up a report/yard map.

It would be a bonus if the arborist also were able to tell us which other new types of fruit trees would take well in our yard. (Apparently we're not content with the work we already have waiting for us!) Fruit tree puzzled


Try Brad Cazden for your fruit tree needs. bradcazden@gmail.com

He'll train you in how to maintain things for yourself. He's a local businessman with a very friendly and caring attitude. His in the business b/c he likes trees and the outdoors. He won't soak you or try to get more work later, unless you need him.

He helped us in exactly this way with our very old/unmaintained grapefruit tree. Steve


I highly recommend Michael Lang. He knows a lot about fruit trees, and he is excellent at pruning them (he only hand prunes, and he does all the work himself). He is a patient and excellent teacher. He worked on my walnut tree and has pruned fruit trees for friends of mine. He has excellent local references. AND he is reasonably priced. Contact me at my e mail or contact Michael directly, (510)841-7749 Michelle

Nov 2008: Dead tree removal and trimming needed in Lamorinda

We have a dead tree and lots of others that need shaping, trimming and, in a couple of cases, possible removal. Can anyone recommend a fair-priced, reliable, bonded tree service for these kinds of jobs? Many thanks. Cheryl


I would call Adrian de Jong for your tree removal at a reasonable price. He also does stump grinding. He's a very hard worker, who specializes in irrigation and landscape, and does a beautiful job thinning trees. His former boss said he was an artist. He can be reached at adejonone@hotmail.com and 415-774-6279.

I would like to recommend Graham Tree Service. They removed part of our Deodar Cedar tree which had fallen on our roof and also trimmed the whole tree. They had a reasonable bid, were super fast and responsive, friendly and very knowledgeable about how to trim our 100-year old tree so that it'll be safe and healthy in the future. www.graham-tree-svc.com, (510) 383- 9585, cell (510) 224-0478.

For the person looking for garden help in Lamorinda, I highly recommend my gardener Luis Ramos for yard and lawn maintenance. Luis has trimmed my trees and I believe can remove dead ones depending on the size. Luis has taken excellent care of my front and back gardens for about 5 years. He (and his crew) weed thoroughly and do a great job trimming plants and trees artfully. He also did a wonderful job installing and maintaining my irrigation system. Luis has always been dependable and willingly tends to my special requests. He is reasonably priced and I couldn't be happier with his work. His phone number is (510) 967-2246

Tree in front of house has big aphid infestation. Anybody know a good Tree Doctor? anon


I highly recommend Chris Chapman from Horticultural Services. He's come out twice to diagnose and trim an old ornamental pear tree of ours. He can be reached at http://www.treeguys.net or 925-254-1459. Hannah P

August 2008

We bought a house this past April with many fruit trees (apricot, pear, apple, plum, lemon) and we are looking for information on how to maintain the trees. We had been told it is best to prune them in the fall but are unsure as to how we should go about the pruning. We are also considering consulting an arborist, does anyone have any recommendations? Thanks!


Check your local nursery for fruit tree maintenance advice. Evergreen Nursery in San Leandro (San Leandro Blvd.) is a great one and they even have classes in plant and tree care. dianao

We're looking for a good arborist and/or tree removal service. We're not sure if we want to have the tree removed or just cut back and are looking for a reputable service that's not too pricey. Any recommendations would be appreciated! Thanks.


We used Treeshapers for consultation, removal, and re-shaping on a property that had been in a state of ''benign neglect'' for over 20 years. They were fantastic. They gave us a detailed estimate for every part of the recommended work, but also were happy to prioritize our own ''phase one'' work. We were completely satisfied with the process, the pricing, the execution, and the result. Contact is: Treeshapers (415) 239-2420 or info@treeshapers.com

Matt Bowman at Complete Tree Care is great. He has been in the business for a very long time and really knows trees. His number is 883-1748. Tree Lover and Happy Customer
We used Matt Horn (Arborist and Landscaper) for a huge project that involved tree removal and construction of retaining walls and stairs -- and all of this on the world's steepest sloping lot. We were so pleased with the work he did -- everything was finished on time, on budget, and it all turned out beautifully. Moreover, Matt and his team were just lovely to deal with; my five-year-old keeps asking when ''the guys'' are coming back. He can be reached at 510-589-2979. Alexis
I have used East Bay Tree (925-377-TREE) in homes I own in Orinda & Montclair. Victor is so honest & really looks out for keeping the tree healthy & living as the best case. His crews are polite, and considerate of your property & his prices are very fair. - Happy owner of 2 redwoods & 3 oak trees. Candace Workman
Hi, I can recommend Peter Rudy of Big Chief Tree Service at 510-528-3588. Also Bill Fontaine at 510-655-5906. Good luck, Claudia

looking for a good tree trimming service to cut back a tree that is leaning over my chimney. kasey


I highly recommend Care of Trees. They are a little bit more expensive than most, but know the most about trees and take extra good care of your trees and property. Wish I had known better
We are very pleased with the tree-trimming service we recently had from Peter Rudy at Big Chief Tree Services. We interviewed several tree services and he seemed the most knowledgeable. His prices were reasonable, and he was prompt and conscientious about the job. Also, his crew is very nice. His number is 510- 528-3588. Cheryl

We need to remove 3 Giant Sequoias from our yard and are interested in recent recommendations for tree removal services. We also have a Redwood and various other trees that need a good trimming/reshaping. I've heard that the removal people are best at removal and the trimmers are best at trimming - so looking for recommendations in both categories. Thanks. Emily


For tree trimming, I highly recommend Care of Trees. For tree removal, you might try Graham Tree Service. I urge you not to use M&M Tree Service. They gave us one of the cheaper quotes for removal of our trees but were unprofessional, rude, left the property a mess and caused damage. Tree lover
Hi, I highly recommend Peter Rudy of Big Chief Tree Service. I have been using him for nearly 10 years since we moved to Berkeley and wanted to keep our view. I first used Brende and Shapiro (now Brende and Lamb). They were very expensive and I was not completely satisfied wih their work and the clean up, nor were my neighbors whose trees I had trimmed. Since then I have been using Peter. He is very knowledgeable, conscientous and professional. He is also a good mediator if you need to deal with neighbors. His crew works hard and are very good at cleaning up. Peter knows his trees and he will trim them only during the right time of year. Peter and I have shared stories of our kids over the years as he and his wife had kids at about the same time I did. He feels like a friend to me. I would not use anyone else. His phone # is 510-528-3588. julie

I have 2 coral bark japanese maples in my front yard and I am looking for someone that is experienced in shaping/trimmimg/pruning this type of tree. Any referrals are appreciated... Thanks!


I recommend Brad Cazan, a licensed arborist in the Berkeley area. He removed several trees for us as well as some serious trimming/thinning of a very large oak tree in our backyard.

Consulting arborist

Can anyone recommend a consulting arborist? I need to have my trees evaluated for safety and health, but I would like someone who can also give advice about how my trees fit into my garden. What care do they need, recommendations for possible replacement trees, view and privacy issues,etc. Thanks so much! Myra


I would like to recommend Richard Trout as a certified arborist. For a very reasonable fee, Richard came out and spent an hour giving us advice about the health and care of the trees on our property, including some old oaks that we are very concerned about. He helped us figure out which pruning we could do ourselves, and which should be left to professionals. He gave us unsolicitated (and welcome) advice about pruning a large manzanita to maximize the beauty of its wood, and what a difference this made! In addition to his private consulting, Richard teaches arboriculture at UC Berkeley. He can be reached at kalmintrout[at]comcast.net

I recently had a tree removed and feel so darn lucky I've found a great arborist/tree person -- Peter Rudy of Big Chief Tree Service. (510-528-3588) I've hired him exclusively since 1997. His crew is really great, professional, fast and conscientious. I can't recommend him highly enough. Rachel


Jan 2006

Based on a previous review by a fellow Network member, we hired Gray Shaw to prun our plum trees and various other trees. He's been great and very reasonable. However, he seems to be very busy so call him well in advance of when you want the work done. His number is 848-6752. joe

I just wanted to update the recommendation for Lara's Tree Service. I just used the service and after contacting Horatio as recommended here, got an exact quote and a quick response from his team. They trimmed two of our large trees and hauled away all of the debris. They were kind, respectful of our property and good at what they do. Adrianne


We've recently had two separate tree companies do excellent work for us, and I'd like to give them a plug.

We live in the Oakland hills on a biggish lot with a lot of eucalyptus. We're looking to do a lot of work ourselves in reducing our fire burden and switching to native pants, but also recognize that we can't take some of the bigger trees out on our own. Since we know we'll have lots of work in the future, we decided to try out two companies.

The first is Roman's Tree service. We worked with Nelzon (510-781-9831 w. 408 -930-2719 c.). They gave us a very good rate on removing three large eucs, and cutting branches to firewood lengths, $1000 -- we did the hauling and clean up ourselves (since we've found that it's cheaper to get one company to do the cutting and another to do the hauling or to bundle and haul ourselves). Nelzon was professional and courteous, and returned all phone calls quickly. He seemed eager to obtain and keep our business which is better than I can say for some of the larger companies which are recommended through the parents list.

Eric from Maxwell Tree Service (510-339-3879) was also a pleasure to work with. He walked around our property and told us what work we could do ourselves, what work we could defer until later, and what work should be done in the near term. He also recommended a small number of tools he thought we might find useful (and he's proved to be correct). Eric took out a large locus tree that was leaning towards our neighbors house. We cleaned up outselves, which was easy since Eric had piled the debris exactly as we had asked him to. Eric is a Montclair resident himself, and really seems to care about the well being of the neighborhood in addition to running his business.

We recommend both Maxwell Tree Service and also Roman's Tree service for excellent rates and service. Merrilee

I have used Matt Horn Landscaping and Treecare on several jobs. He has done outstanding work, especially on difficult trimming or removing of trees. His aesthetics made my wife and I very happy and his ability to remove a large cedar over my redwood deck without a scratch was impressive. His bid was firm and he stuck to it. I really can't say enough about him except that he's a pleasure to work with as well. They arrive on time and clean everything up. Ask for Matt, 510-658-6088 tom

Horacio from Lara's Tree Service is awesome! These guys came out gave us a GREAT price! did better work than I had expected, cleaned up all the mess they made and then some! And did it in NO time at all! If you are looking for quality work, great prices and someone who knows trees call Horacio at 510/729-8040. They are the BEST!!! brandi


April 2003

We used M & M Tree Service of Richmond. They're certified arborists and were the most reasonable of the 3 bids received. They were very efficient and we're happy with the work they did--a 30% crown reduction on a huge walnut in our backyard. They're in the yellow pages. lw


March 2003

Just sharing a recommendation for Lara's Tree Service. They just did a lot of work for us - trimming, removing, hauling - and did an excellent job. They were very thorough, clean, and took the time necessary to do a good job. Ask for Horacio - 510-729-8040. Carolyn

The Forestree Company is an excellent longterm Berkeley resource. It is composed of graduates from the UC School of Forestry (on the Berkeley campus). The partners are certified arborists. Call 526-TREE (8733) Bruce

Try Forestree Company in Berkeley at 526-8733. The owners are UC Forestry grads (and old college friends of mine), and are reputed to be fair and skilled. I've never had any trees big or interesting enough to try them out! Helen


I recommend arborist Robert Reed, his business of ten plus years is called Fine Pruning. He can be reached at 524-0105. If he can't do the work himself he can get you in contact with someone than can. Donna
I recommend Gray Shaw, a certified arborist. His number is 848-6752. He works out of his home so his answering machine message can be a bit funky, but he's very friendly. We inherited a lot of overgrown trees about 11 years ago, and he's been taking care of them ever since. Fran
I would strongly recommend Trout Tree Service in Berkeley 524-6638. Good on the basics, but also very talented and expert. Mary Jane
Try Peter Rudy at (510) 528-3588. He recently trimmed our 100+ foot redwood and did a fabulous job. Stephanie

What kind of fruit tree for Berkeley Hills?

Feb 2009

Looking for recommendations for fruit trees. We know we need to get dwarf varieties. We live in the Berkeley Hills and have a Meyer Lemon that does well. I'd love to have a cherry tree. Can anyone recommend one suitable to my area? Can anyone recommend any others? Also, where is the best place to buy? Thank you in advance.


Just because you're space limited, you don't need to get dwarf trees, just get standard trees and prune them to the size you want. This is Berkeley Hort's philosophy, and it seems a good one (and you ought to check them out, as they run free classes, e.g., on pruning fruit trees)... when trees are bred to be dwarfs, they're selected for size, not taste, etc. Trees that seem to do well around here would include figs and apricots... peach leaf curl dissuaded us from nectarines. If you want a deciduous tree, you might try persimmon (or fig), though the squirrels do a number on ours almost every year... when we can wrest a crop out of their nasty little paws, they're quite tasty. But do talk to Berkeley Hort re dwarf vs. standard varieties. Albany Gardener
There are lots of wonderful local nurseries, but I think the best one for help choosing edible plants and trees that will thrive and produce in your location is Spiral Gardens at 2830 Sacramento in Berkeley. They have good inventory, too. I also got good ideas on the Bay Friendly Garden Tour last April. Heidi
We live near the campus in Berkeley and we adore our Santa Rosa plum. I think it might be a semi-dwarf, which is a great size for a patio area. Just don't go away at the end of June, beginning of July or you'll miss the plums! anon

City of Berkeley Tree Planting Program

March 2005

Our neighborhood in N. Berkeley is in the process of using the tree planting program to replace several trees lost in the 80's drought. If you are a Berkeley resident who took advantage of this program, I would be interested to learn which tree species you chose and the plusus and minuese of that choice. Would you choose the same species again? If not, why not? There are so many to chose from, and although I have gotten the list of trees as well as read up on them, it is difficult to decide what will work best. I would welcome any feedback! sarah


My former block in Berkeley had chosen the Liquid Amber trees. I'm not sure if they are still on the list, but the block regretted the choice because they drop a thick sap that is very hard to get off of cars. anne

Tree is dripping sticky stuff (aphids)

Sept 2006

I've seen the archives about people who will trim or move your trees, but I'm looking for someone who can tell me if my tree is sick. I'm not sure if those are the same people or not. The tree next to the street in front of my house in North Oakland drips this stuff off it that gets on your car if you park under it. And now the tree has black spots on its leaves and what look like white spots on its branches. I need someone to tell me if there is something wrong with the tree, and if so, what to do about it and if I need to get it trimmed or doctored

What's Wrong With My Tree?


I am not a tree expert BUT it sounds to me like there are aphids in the tree - which is pretty normal. Ants like to farm aphids so if you see ants going up and down the tree trunk, there are probably aphids. The ants are aphid ranchers and feed on the sweet ''honey dew'' that the aphids give off. The honey dew also falls out of the tree onto leaves and cars. Its stickyness makes it gather dust and leave dark specks. Since you say you see white spots on the tree, it may be scale bugs, too, which i think can also be associated with ants. On small trees if folks want to get rid of the aphids or scale, they put sticky ''tangle foot'' in a ring around the trunk so the ants can' get to their herd. I recommend that you take a leaf with the white stuff on it to a good local independant plant store and ask them. In my neighorhood we go to Berkeley Horticulture for advice. Up at the UC Botanical Garden, a retired professor (Rabbe?) used to do a fabulous plant clinic once amonth or so. Folks would bring in their bits of sick or infected plants and he would tell you what was wrong with them ...for free!. He is an amazing font of knowledge and others would hag out just to soak up some of his expertise. Call the UC BOt Garden (google for the number) and see if they still do the clinics Garden Mom
Sept 2008

As an arborist, I think you can take care of aphids by yourself. First, if the tree is in a bad location or is getting too much/little water, light or fertilizer (most often too much fertilizer), correct this problem first. Mulch under the dripline if that's not already done. Second, get a strong pressure nozzle for your hose and knock off as many aphids as you can. They won't climb up again. If there are ants managing the aphid colony then put tanglefoot or another sticky substance around the base of tree and check every few days to make sure they haven't bridged it. If none of this works after a week or so, my last resort is to get neem spray, and while using COMPLETE PROTECTION (eyes, mouth, skin) apply this to the affected parts of the tree. Never taken me more than two applications to do them in. Neem is an organic, but obviously still potent enough to do the job, so treat it like any chemical. You can get it at Berkeley Hort. It's used in toothpaste as an antimicrobial, so it's safe in small amounts, but I wouldn't push it. And of course, this is a general recommendation, as I haven't seen the tree. Good Luck! molly


Green figs, not purple

Sept 2006

Does anyone know where I can buy a green fig tree? (We don't like the purple ones as much.) Thanks! Figless-on-CurtisSt


We bought a green fig (Conadria) at Berkeley Hort a while back and it's been great. It was just a bare stick (!) but it's totally leafed out and is going crazy with delicious figs. The nice thing about green figs is apparently the birds don't go after them as much (they think green means un-ripe) Fig Happy

Elm trees sprouting up all over our yard

We have a big backyard and there are tons of elm trees sprouting up all over it and there is one big old stump. Is there any non-toxic way to get the elm to stop sprouting up and trying to create an elm forest in our backyard?

I am no tree expert, but I heard that pounding some copper nails in a tree stump will kill the ability of the tree to sprout. So you can try this, or have a tree contractor grind out the stump. dr

Birch Tree Shedding Seeds EVERYWHERE

March 2005

We are having a problem with our birch trees shedding small, brown, paper-like seeds EVERYWHERE. These little things are invading our house. We recently had work done to our home and I am wondering if there was damage to the trees during this process as I don't remember this ever being a problem prior to the work. I am not sure exactly what type of birch trees they are and have looked on the internet but didn't find an absolute answer. Any information would be greatly appreciated. I am absolutely fed up with having these things take over the exterior and interior of our home. looking for a solution!


The only reason that your tree would be producing more seeds now is if it was damaged in some way and is trying to make sure that it leaves progeny behind if it dies. Some plants will almost always do this, others only sometimes.

By next year's 'seeding season' you should have some evidence as to whether it is either dying or recovering by whether the heavy production is still occuring.

This is an educated guess from a horticulturist! Get an opinion from a licensed and experienced arborist as to the tree's health. I would recommend calling Brende and Lamb for this sort of thing (510-486-8733). They are good at evaluation whereas many tree companies are really only good for basic pruning and removal. Unless you want to just go ahead and take it out? There are tree companies for this purpose in the archives. Cecelia


Spraying Oak Trees

March 2004

We received a flyer in the mail from Gring Pest Control asking if we wanted our Oak Tree sprayed to prevent sudden oak death from ''Spring Oak Catepillars.'' We're wondering if anyone has any experience dealing with Gring and if they do this Oak spraying on a yearly basis. Any advice is helpful, as we have a large oak in our backyard that we'd love to keep, but don't know anything about this particular service. Thank you


We discussed this company in my Arboriculture class! According to my teacher, this is a scam!!

First off, there are many different Oak species and only some have gotten Sudden Oak Death (the Tanbark Oak), -and- this disease isn't a problem in the east bay (yet).

You don't need to spray your tree if it isn't sick, and the one and only spray that has been approved in treating sudden oak death isn't the one that this company sprays. Your best bet is to call the Alameda County Master Gardener volunteers for more information! 510-670-2200

The most important thing is that there is no reason to spray and treat a healthy tree. Especially with a chemical that is not approved by the International Society of Arborists (ISA). - Candace


Oak Moth Caterpillers do not have anything to do with Sudden Oak Death, and I can't believe that any responsible company would promote such an idea!

Oak Moths cause damage to Oak leaves for a fairly brief period in the Spring when the larvae (caterpillars) are voraciously feeding (the adult moths do not cause any damage). If less than about 1/4 of the leaves are affected and the tree is otherwise in good health, don't worry about it- the tree can handle that. But if the damage is extensive, &/or the tree is not in great shape to begin with, action is recommended. (If the tree's not in great shape, get a consultation from an experienced certified arborist to determine the larger problem).

There is a very effective biological control for Oak Moth larvae called BT- lethal for them, innocuous to us and other critters. But it is only effective if it is sprayed on the larvae when they are actively feeding, so you must watch your tree closely for their appearance, and then spray right away. A spray too early or too late does no good.

I use Vern McQueen for landscape spraying, 841-2782. He has a Pest Control License, is reasonable, and is a very nice fellow. Cecelia


do NOT do it at this point in time. For information about Sudden Oak Death call the Master Gardener office (Alameda Cooperative Extension) at 510-639-1371. Leave a voicemail if the phone is not answered and someone will get back to you in a day or two. MG
Sudden Oak Death and Oak Caterpillars are two entirely different problems. Try the UC Davis website for more info. http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn7498.html http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn7422.html sunsol
