Please Help! I need help figuring out what's going on with my Chollipo Euonymus. I have 15 of them in my backyard, and about a month ago, one of them started having problems, and now they all are. The problem seems to start as having leaf buds that turn brown and don't open. Then many of the leaves on the plant start browning and falling off. New leaves that are trying to unfurl are shriveling up. The original euonymus that first had the problem looks bad now (in image). I never saw any bugs or scale on it (I googled scale to see what it looks like). Now many of the other euonymus are starting to show the same early signs of trouble. I do see some spider webs on some of the other euonymus and I don't know if that's related or not, as the spider webs don't seem to be visible on the euonymus that are doing the worse, but maybe the bugs have moved on to the healthier euonymus and are getting ready to inflict more damage. The euonymus are planted on a slope in mostly sun in clay soil that was lightly amended with compost at planting time (planted June 2008). We have had a cool wet spring here in Richmond, Virginia, zone 7, and then the past few days have been in the 90s. I have drip irrigation for the euonymus but have only turned it on twice because of all the rain we had this spring. Any thoughts would be appreciated.
