i had 3 conifers in my front garden for the last 5 years and they grew to about 7ft but then they gradually turned brown until they died. i have another 6 but they too are turning brown. can these be saved ? did a fungus killed them ? can i replant new conifers in the same place ? i really dont know what to put in it's place
I have over 20 cone shaped/ pyramid shaped conifers ? arborvitae holmstrup or emerald.They are about 6 ft in height and were planted over 6 years ago.In the last few weeks brown patches have appeared at the bottom of the trees and has spread throughout 2/3 of the trees. While on other trees areas at the bottom of the tree have turned black in colour as if they were burnt .Could you please tell me what has caused this and what i can do to treat it . Thanking you.
I am desperate for help. I bought a buxus last summer to place just out side my front door. Since the beginning of this summer I noticed the leaves aroud the bottom area turning yellow, brown and eventually falling off. I repotted the plant and noticed that not all the roots had been covered by the soil in the pot as they weren't packed correctly. The bare area at the bottom is now creeping its way up and it's taking over the plant. The leaves at the top are now turning brown too. Is it a mite infection or am I not watering it enough? The soil is wet to the touch but not over sodden.It is placed in a sheltered area which gets a reasonable amount of sun.
Gerry, we have an evergreen hedge with small leaves. Currently two thirds of the hedge is looking very bare and the leaves that remain on it have brown spots on. In the centre of these brown spots are white spots. The entitre spots are 5mm across and there are as many as 20 on each 2cm leaf? Advice please on how to save the hedge!!!!
Hi Gerry, I have two bay trees in pots in the garden. About 5 ft tall and have them for 4 years. In the last week one of them is completly covered in small black flies (1-2cm long), nothing on the other tree. They seem to be eating the centre / side of some leaves. The other tree has no flies but some leaves are yellowed, curled and stuck together with sort of cobweb in the centre when pulled apart. I'm totally confused between psyllids, suckers etc so not sure if I just spray them or need to remove all damaged leaves and then spray? Many thanks
Hi GerI have a weeping willow (planted in May) which is now full of this unsightly yellow powder and the leaves seem to be drying up and dying. What is it and is the tree any good or will I have to take it up. Will this disease affect the bulbs I have planted around it?Many Thanks
Hi Gerry, I seem to have a back mould kind of thing on the leaves of a hebe with a purple cone shaped flower ... not sure oof name.Do I say bye bye to my lovely plant, chop it out or can it survive this horrendous attack.Can supply photo if that helps. Thank you
Black spots on trees and shrubs causing plant to loose leaves early. Trees include cherry blosom and willows
I unfortunately stripped the bark from the base of a very young brich when strimming. The damage is about an inch in length but doesnt go completely around the tree. What can I do to save the tree or is it a lost cause.
Hi GerryMy rhododendron has some green fungal disease on the older leaves. It look like thin film of green algae - like a green powdery midlew.What is it and how could I use to eradicate this? Thanks
Our tree which is well established has turned brown and appears to be dying from bottom to top ie. turning brown with a sticky syubstance oozing through the bark. A clematis that we had planted this spring to grow up it also seems to be dying ie leaves growing then dying back.I think it might be a fungus. Is this probably correct? If so, can it be treated or should I cut it down and remove it?
what could be causing my new clematis to wilt? would the recent wind and rain be anything to do with it? where my patio is situated is fairly open to the elements and i dont seem to have as much luck with my gardening since i moved here. I have planted a lot of flowering plants before in other abodes, but by times i really loose heart with the results of my efforts here.
I have just noticed that a young hawthorn Paul Scarlett has a portion of bark missing from the bottom of the trunk. It measures about 6 inches long by about 1 inch wide. What animal could have done this can the tree survive?Is there anything i should do now? Regards ,Bobbi
I have a Bay Tree in a large container. It has been doing well until the last month. It has now got little brown scaly lumps under the leaves and a lot of the inner leaves near the trunk have turned yellow. Do you know what is causing this?
