For the third year in a row, what I believe to be 'black spot' is killing English Ivy in our neighborhood. Still the ivy hangs on. What can I do to stop the spread of this problem? We have huge amounts of ivy all around, mostly in shade.

There are both bacterial and fungal leaf spot diseases that afflict English ivy. The shade is probably a big factor -- without sun to help dry leaf surfaces, these diseases can become entrenched. Thinning the vines to increase air circulation might help a bit, but before you procede with any control measure, have the disease properly diagnosed by your county extension office (ph# 358-6400). They can help you decide which control measures to use. You may find that the ivy just won't thrive in the hot, humid shade, and you'd be better off with a different vining plant to take its place. Best of luck!
