I live in Marin Co. California, where summers have been mostly hot and dry, winters mild with rain. All my plants are in pots, excepting the trees that were already here when we moved in 15 years ago. This year my tomato plants again look pale and scraggly, with strange tunnel-like marks on the leaves. Tomatoes taste fine, mostly cherries.
My roses and fuschias also look like hell, leaves look spotted or purple-y, and few to no blooms. I've given the 3 roses 3-in-one fungicide/insecticide twice this season. My rhodie has a fungus again, and my Japanese maple up and died!
I'd love to know if this is related to global warming (it has been 95 or so most days this summer) or something about the soil in the pots maybe? I'm giving some fertilizer, not a lot -- regular but not frequent watering. Other plants are doing all right, but some not blooming.
