3 7' trees planted on slope now in two years the lower one is fine. Higher ones have hardley any leaves and few flowers. Even though it is ex farm land the soil is not great. Would feeding them ensure they do better next year. Last autumn the higher ones changed colour and lost their leaves first while the other one still had green leaves on it.
if feeding will help what type of feed is recommended. Thank you.

I have a griselinia hedge lined avenue which is 30 odd years old it has formed an arch which I would like to maintain. the only problem is it seems to be dying on me. I have tried to cut out as much dead wood as I can. It has new shoots but these quickly loose their leaves and become bare and also brown or black at the tips. What could I do it would be a shame to loose this beautiful feature. Is pruning an option because these are now more trees than shrubs. thanks
