A few days ago I noticed that the leaves at the tips of the branches of two of my 3-year old cherry trees have curled, and inside the curl are what appear to be black aphids. I have sprayed with an insecticide but of course couldn't reach the top of the trees. The aphids seem to have reduced but are not gone. Are the trees likely to overcome the problem?
The top of our clematis is wilting. it approx 1.2m high planted in a large pot.The rest of the plant is fine .Much obliged for any helpthankPlease could you advise.
I have a driveway with lawsons cypress either side. Not sure of age but would estimate maybe 15 to 20 yrs. On one side, one tree started to deteriorate last year, now completely dead. Symptoms beginning to spread to trees on one same side of drive. I can't find any sign of pest infestation such as scale insects, aphids or environmental damage so I am suspecting honey fungus. Apart from digging out tree and roots which I don't have the means to do, Is there a more practical control to this problem if honey fungus is confirmed?
I have a 2 yr old beech and white thorn hedge doing well 🙂 The problem is the beech are covered in what i believe to be fluffy aphids. What do you recommend i do ?
Climbing hydrangea planted last Autumn on a south facing wall. It is thriving but something is biting at some of the leaves. Can you help please with solution. I have planted one also on a North facing wall and the leaves are totally healthy and it is also thriving very well indeed.
HOW can I discourage/prevent large birds..crows and magpies ...from feeding on my bird table,and feeders .....the smaller birds are being hunted away altogether!!
I recently planted 80 bare root ash trees in a field near my home. When I was looking at them the other day I noticed that the stem (or trunk) of some of them have being chewed half way up. They look like they were cut at a 45 degree angle by secateurs. I presume that it is rabbits that causing this problem, so I was wondering how I might be able to deter the rabbits from going near them? Is there a natural spray that I could put on them?
my garden has attracted a load of flying midges and not just around plants,causing kids playing out there to scratch.Now only last evening I fed plants with a tomato feed and that is the only real change added to the garden. Is this the reason for attrracting them or what is and what can be done?
Please can you advise on this problem. This happens every year after flowering when leaves appear, when can we spray the tree to prevent this and with what?
I planted a rosemary last autumn and it seemed to be thriving, but has died, possibly due to the cold weather. I dug it up today to dispose of it and discovered an abundance of yellow balls, about the size of coriander seeds, in the rootball. I squeezed a few and they burst, the insides a bit like dandelion milk. What are they?
We had limited success with clematis, last year was first year and it got a white fungus which inhibited growth. Any suggestions for this year to prevent a reoccurence?
I have a 150 ft long hedge, it is 15 years old and has lost almost all of its leaves, those remaining have black spots as do the new leaves starting to appear.Almost all escallonia in our area seem to look just as bad. I am considering digging it all up and replacing it with Laurel,do you think there is any point in giving it another chance or will it more than likely suffer the same fate next year ?
yesterday while out inspecting the spring progress of my garden i noticed that one of my 3 alder trees was covered in green fly. I had intended washing this off this morning with soapy water ( which works for my lilium in the summer) but this morning rain has prevented this.My question is why is this tree being attacked. It was planted last spring and is other wise healthy. I have Scots pine, willow, ash, hazel and haw thorn planted nearby, are these susceptible too? i prefer not to use chemicals in the garden.
Some snails around but don't think they are totally at fault. How can I save three large Fatsia? I was told it could be a flying insect?
