I have a 4 year old cherry tree, however I have noticed some of the leaves are covered with black bugs and the leaves are curling up. Can you recommend a treatment?
I notice that my Victoria plum trees have a very sticky substance on leaves and fruit. Could you please let me know what is causing this and if there is anything I can do now to remove it. There is a very heavy crop which I have already thinned.
About 6 weeks ago I planted a bare root Stella Cherry. I live in Central Scotland with a very sticky clay soil.There is no growth whatsoever but I rubbed off 1 bud, it was dead then another and it was green underneath, but still no signs of growth.Do you think I have lost it or do I prune it and leave it or just leave it, talk nicely to it and hope for the best. The weather here is a bit warmer now but still quite wet. I would hate to lose it and am about to plant a Victoria Plum with is now in growth within its polythene pot.
I planted a plum tree seven years ago it only produced fruit last year only two. It is situated between apple trees that are flush with fruit every year. The plum tree produces blossoms but no fruit. Any help please
I have had a plum tree for about 4 years, and every year up to last year, there was a fantastic crop.Lat year, there were about 3 plums on the tree.This year (now its April 2nd) buds are just starting to flower and they look fine. Is there anything I need to do . Will I get any plums this year
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!
This year we found our crop of damsons to be inedible due to the presence of maggots in the fruit. Is there something we can treat the tree with to prevent this happening again next year? Thanks.
My Plum Tree seems to have some sort of disease, towards the end of July, there seemed to be a lot of flies and wasps on the leaves, now all the leaves have little holes in them, the fruit have slits on them and there are flies and wasps eating them. Overall the tree looks unhealthy with the leaves wilting now.Also the beech hedge seem to be full of little white flies, and some leaves looked very black and dead now. What can I do.
Hi Gerry, I noticed earlier in the week the damsons are starting to ripen, but some of them seem to have what looks like rust spots - could this be the brown rot - or do i need to do a little more investigating of the damsons?The trees were in the garden when we moved in 5 years ago and last year there was a bumper crop, this year there is a lot of fruit on the trees, but i am worried about the brown patches on them.If it is - what do i have to do at this stage?Kind Regards ,Lorraine Keely
Hi Gerry, I planted a cherry tree " Stella" 4 years ago and it is very healthy. Every year it has a very good crop but then the fruits dry up, shrivel and fall of the tree. This year there were about 10 edible cherries but even then they were not as plump as they should be.Could it be that the ground is to dry directly after flowering? We had no rain during the entire month of May this year and last year.Thanks Clair
I first notticed a lichen that developed on a Victoria Plum tree which seemed to cover the bark of the branches eventually killing them. I firstly cut off the affected branches but tree later died anyway.This same lichen has now spread to a number of other trees, including apple trees, ash and oak trees and blackcurrant bushes.I hope there is some advice you could give as to how to protect the trees and save those now affected.
the tree went in two years ago as a whip, had seven fruits last year and is very vigorous, with much blossom and beginnings of fruit this year. but now single branches have wilted and died, initially the lowest couple but now higher in the tree. i think it might be verticillium disease but can't find what to do about it - any suggestions?
