Pyracantha leaves turning black

ollie dillon asked 12 years ago

What can I do to reverse the pyracantha leaves turning black (without having to cut it out???). I have a row of about 5 along a low back wall, the top of the pyracanthas which act as a screen allowing additional privacy. The top two feet of one is particularly bad. The leaves on a few side branches of the two adjoining pyracanthas are also turning black.

This is probably pyracantha scab which is similar to rose blackspot. It can cause severe damage to the foliage and berries  and plants are often taken out as result.

You can spray with a rose spray, such as Roseclear, but this may have to be kept up if symptoms remain.
