I have a mature cherry tree inherited with the house 4 years ago. It has only produced 1 cherry in 3 summers. Blossom & leaves are fine and we get pea sized fruit on stems then suddenly they are all gone before they have a chance to ripen. 2 years ago some branches developed a sticky substance oozing from them and the blossoms looked burned. I cut off these branches and dumped them and it hasn't recurred. Are these related problems? Do I need a special feed? Tree seems healthy otherwise so I'm reluctant to chop it down and start over. Help!

i have a witch hazel,Arnolds promise and it started off with about 5 fine branches which were full of leaves about 3 years ago. i'm now down to 2 main branches which have flowers but it doesnt strike me as being the healthiest. it is on good soil but the site is fairly exposed, though other shrubs and trees are doing very well.i was going to replace it last year.would i be as well off digging it up or giving it another year to improve

I have a hedg of Griselinia (approx 200 plants) and there are a number of them that appear to be dying. The leaves are turning yellow (with light black spots) and then falling off. Can you tell me what this might be and how can I treat it.
