South east England. One - raspberries.Two - plums.

Autumn Bliss. Plants about five years old. Excellent crops until this
year. Very poor and the leaves on several plants have lost their
"green-ness" Prune to ground level every year about January and feed with
Growmore at that time.

Victoria Plum. About 20 years old. Never a very good cropper, but a
couple of years ago produced a bumper crop of excellent fruits. Last year
about half-a-dozen and this year nil. Prune two thirds of last years
growth in early Spring.

Any suggestions?

I suggest you post this question in uk.rec.gardening where there are many
very experienced gardeners who have a lot of knowledge to help you.
