Lack of flowers on Rowan tree this year.
Hi everyone. I have a beautiful healthy rowan tree that has been covered with flowers then berries for the last 2 years. This year I have lots of healthy leaves but not a single flower. Can anyone suggest if there is a feed I should be giving it? We have clay soil but this is not a problem as it has flourished and is still growing very well, just lacking buds. Grateful for any advice. Thanks Judith
