I was a Botany major in college and have been a lifelong plant freak, but now I take care of animals for a living. Anyway, I have had an ongoing issue with scale on several of my pine and juniper bonsai. The scale itself appears to be running rampant here in SE Massachusetts. What is your prefered method of dealing with this pest. I've used dormant oil and isotox with mixed results.

However, almost every branch has these red bumps on the leaves. There are leaves that don't have bumps, but have a discoloration and/or curled. The bumps are at right angle to the flat top of the leaf. Last year I noticed something similar except the bumps were green, and much fewer. I picked them off whenevery I found them, and after awhile I didn't have any more. The consensus at the study group, ...

I dont have a picture yet, so Ill just write a small text about it. I have seen that on every tree I have, there appears to be some kind of white fungus on the edges of the pots and on the trunk. It comes from the soil.. I have taken it away several times, but it comes back in a just 2 days or so. Do you think it could be a problem? The only problem I have seen is that it doesnt look good.

This article doesn't mention this, but it's strongly suspected that colony collapse is more prevalent in stressed bees, and the stress could be any number of things, including exposure to pesticides.

In mid Feb I re-potted the tree and noted that root growth was not particularly extensive althought the tree had thrived over the past 2 years since I aquired it. I did no real root work on the cotoneaster but carefully re-potted in my usual porous mix of Kittydama, Akadama, bark and Hydroleca. At this stage the tree had, as usual, stayed green and ...

I think I've found a solution. Chickens. I suspect, however, that you'll have to move to the country to take advantage of this solution, since few towns like them wandering around free (or caged for that matter). At any rate, since we inherited the neighbors brood of fighting cocks and hens, we've hardy seen a Japanese beetle -- not even on our Rose of Sharon or on real roses. They forage everywhere ...
