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.
Dear Gerry, I'm a novice gardener. Last year my mother gave me two potted small fern trees (box/bux? I think she called them). One is thriving but the other has a lot of brown and hasn't grown at all. When I realised the pot had no drainage holes a few months ago I remedied that and then this month added a new layer of compost. It still looks miserable next to its healthy neighbour. What would you recommend to bring it on?
I have a beech hedge which I planted bareroot 3-4 yrs ago and it has never properly established. Each year in spring time the buds/leaves burst and flourish out and it seems like it is doing well, but then by around mid June, it seems to stop growing. Some plants die, some turn yellow, some wither away and it generally looks unhealthy. I do water it if we have any dry spells but doesn't seem to make any difference. I have lost about 20% of the plants each year and have been replacing them each winter but I need to find out what the problem is. How can I find out what the problem is?
I think it may be too late to save, one of my Buxus balls has turned yellow and basically looks dead?? I've given it miracle-gro and for some reason it hasn't come on I would like to know why you think this might be? In the picture you can see a second ball that has growth this season??
I got 2 Pittosporum evergreen shrubs last year. They are in pots outside the front door and are very much exposed to the elements. I haven't been watering them as they get a fair bit of rain. One of the plants in particular has started to wither - see pictures attached. Just wondering if you would recommend anything to save the plant ?
Purchased this tree, japanese maple - dissectum Garnet, two/three months ago and repotted it some weeks later into a larger deeper pot (see photos) in John Innes 3 and also put gravel in the base for drainage. As you will see from the attached photo, it is situated in a sheltered location which gets plenty of morning sun which, I understood to be the ideal for this species! Unfortunately, the foliage is showing signs of withering. What could be the reason?
My 5 year old camellia (potted) started budding for the first time this year. However the leaves and buds have turned brown.
I have a Daphne Astrid that I bought 3 years ago (25euro) I have it in a container on my patio which is south facing and sheltered, I also top dressed it last year. It is struggling, I am desperate not to let it die.It is very bare with a few leaves at the top, I have never pruned it then again it hasn't grown much since I bought it.
this normally beautiful tree is a big disappointment this year. its planted about 5 or 6 years. i dont know if its because of the rain or what but it hasnt leafed up well at all. it seems to have struggled a lot. other acers are doing as well as always. is this one just tempermental? do you think its dying?
