I have a variegated holly with black kind of scum on the leaves. The holly is 4 foot tall doing well but should I be worried?
Attaching photo of diseased leaves on Daphne 'Jacqueline Postill' - quite a small young plant. Please advise treatment.
We have a wintering flowering cherry blossom that has suffered from blossom wilt the last few years, getting progressively worse. Last summer all the only leaves were at the very top of the tree, and there were no flowers this winter. Is it worth cutting back the tree hard to see if it will recover, or is there anything else I should try before cutting it down? It is a beautiful tree and we would be loathe to cut it down.
Our lovely mature variegated Holly (about 25 ft) is shedding leaves in one section. The leaves are blackening at the tip and are falling off promptly afterwards. It is spreading rapidly. I have been collecting the fallen leaves and tried to cut back the affected branches, but i can't control it. We are after the wettest December on record so I fear it my be related? Can you please give me advice as I fear losing this amazing and essential tree!
This Acer has being dying down one side over the past few years. I have cut off the branches as they died. There are now only the leaves shown left & these look fairly healthy. Can you tell me what has happened & if the tree might fully recover?
My Leylandii hedge is turning brown like if it's dying. Can you tell me what might be wrong it's about 18 years sowed?
I have a Robin Red and a golden maple next to each other. Both are covered in a tiny black insect. On the maple the insect appears like black spots on the leaves. On the Robin Red the insects are grouped on the stems. What is the best way of treating this? Thank you.
i keep finding this white stuff on dead plants in my indoor garden. Is that what is killing my plants? Please see photo attached
I planted some hoheria trees last year but the leaves have some type of fungal disease. There are small black spots on the underside of the leaves, the leaves turn yellow and fall off. I sprayed with Rose Clear Ultra and it definitely helped but the problem seems to be returning again. Do I need to keep spraying or should I replace the trees? Any advice would be appreciated. thanks.
We have a holly JC in our garden for the past 5 years (see photo). The bulk of branches are low to the ground and more sparse mid and top of the shrub. The leaves are also being eaten by pests. Is it too late for me to prune the lower branches and any ideas on pest control. There are pieces of leaves missing as a clue.
Why would an Aucuba japonica suddenly begin to wilt? It has been in place for a few years. The leaves have what looks like wind damage also.
I planted a Elaeagnus x ebbingei hedge 2 years ago. It has always had these insects on it and I kept them at bay by individually washing the leaves. But now it is too big and is suffering badly! There are about 16 plants and all affected. Myrtles in between are fine. Leaves have yellow patches on upper side and grey/ black powder on underside. Insects also on underside. White waxy stringy deposits on tips of branches during summer.
When raking up some leaves today I came to a pile of sycamore leaves. Most of these have black spots on them. My question is: Is it ok to add them to my leaf compost heap? Or is this a fungus that will infect plants where the leaf-mould is used?
I have a problem each year with my lilac plants, in county Monaghan. The leaves turn brown and curl up and fall off. It appears from previous "Ask Gerry" questions by others that it may be honey fungus damage. What is the treatment for this condition.
