The wasps that have been buzzing around the peppers for the past couple weeks still come by occasionally but not that often. Instead of the six or seven I see constantly hovering around and licking honeydew from the pepper plant leaves I now only see one or two at a time and they don't linger long. A couple weeks ago I noticed that the aphid colonies on my California Wonder pepper plants were thriving so I blasted them with a rather potent solution of neem oil and dish soap. Not much different from what I've used in the past. I sprayed the plants a few times before leaving town for a week. That was two weeks ago. Now the aphids appear to be gone or at least beaten back significantly. And I figure the wasps aren't hanging around because there aren't enough aphids to produce honeydew for them.
But aphids are only one problem plaguing the California Wonders. I planted them up high along the edge of the balcony half wall to provide maximum sunlight. Unfortunately being up there also means maximum wind exposure. And these poor plants really take a beating. Every leaf has a tear or rip or hole in it. Despite this, they continue to put out flowers. But it's a bit too hot for fruit set. On one plant I have a single pepper, perhaps a little bigger than my fist. And on the other I see a couple of new peppers starting to form. Perhaps now with the aphids in retreat things will get better.
