I have a mahonia which is about five years old. It had lovely leaves and yellow flowers. Since the bad cold spell all the leaves have fallen off and the stalk is the only thing that is left. Is this dead or will it re-sprout again and should I feed it?
I have two Photinia Red Robin, looking smart and growing nicely but shedding an awful lot of leaves. I have one in the front (east facing) and one in the back (west facing) and clay soil.. There are also spots on the leaves. There is plenty of new red growth and other than that they look fine. Is there anything I can do to prevent or slow down the leaves falling? This part of the garden looks like autumn.
Some plants on my 5 year old, otherwise vigorous, Griselinia hedge (in city, fairly sheltered, sun in afternoon) have developed pale, irregular spots on leaves, any part of leaf but especially nearer tip. leaf turns yellow, some have brown at tip, then fall. Neighbouring yew, skimmia and box ok just now.I'd be glad of advice as more and more leaves affected over the last 2 weeks.
Grisselinia hedge - well established - 8 years. No leaves at all at the moment and no sign of growth. Will this hedge recover or is it finished. It is a boundary hedge between our neighbours and I can now see through the hedge into their garden.
I have had a huge plant which has been the centre piece of my garden for about 15 years. I believe it could be called Cordyline indivisa - with seven stems and about 12 -15 feet in height. It seems to have been completely destroyed by frost. Please dont tell me to cut it down. What can I do with it?
My two fuschia shrubs are showing no signs of life .Have they been killed by the severe frost over the winter? One is ten years old and is a very large shrub.The other is three years old and is much smaller.
My beloved cyathea dealbata tree fern (10 years old) looked as though it had succumbed to the fierce cold of the previous few months. I do, however, see some tiny green fronds appearing from the center even though the other old foliage is black and dead. What is the best way to proceed. Should I cut away all the old, black fronds (they look dreadful) or would that cause further stress to the tree?
Mimosa tree lost all leaves and branches seem dead.Dimosa 'pink fountain'brown and falling foliage,no new growth anywhere. Sweet pea shrub, planted last summer,lost leaves since winter,no sign of life Are they really dead?
My Acer has some branches with black tips - is this frost bite and should i prune them back now?
Yucca frost damage, all of the yuccas in my garden and my neighbors have suffered frost damage. Should I prune the tree or leave nature take its course...

Is there any cure for Camellia frost. I seem to have lost a beautiful plant and wonder if there is any way to restore it.
Last Oct a severe storm hit my area and completely stripped bare all my escallonia hedge and Gold Brian shrubs, theres nothing left just twigs, actually everyone in my neighbourhood suffered the same. My garden items are 10-15yrs and never before has this happened. What can I do for them now. It is so sad to look at them now after all the care I gave them.
I am aware that the recent snow has caused severe problems for cordylines. Just wanted to know how I should treat my 7 year old cordyline. It is in a very open space and is the centre piece in my front garden. It is now about 4 feet tall - has split into three sections. The recent snow and ongoing cold has started to rot the tree. I am very concerned as it has started to rot from the growing tips and the new growth is starting to fall.. Will it regrow or is it dying? Please advise
