I've never given them special feeding. I don't feed anything in the
garden apart from mulching with compost whichever bed has reached the
top of the priority list. I don't think the cherry bed has had a mulch
in the last 5 years.

It has perked up now! It's going to blossom along with the other
cherries, I guess....
