2 years ago I planted 4 chaenomeles 'Jetrail' against a fence in a semi-shaded spot in my back garden. To date, only 1 has bloomed. Any ideas as to why the others haven't yet when conditions are the same for all 4? Do they need more time to establish themselves maybe?
I am creating a native wood in my back garden. I have 4 x 4 m to play with I am wondering what density of trees and shrubs I can use for canopy and shrub layers. eg. Canopy trees 2m apart and shrubs in between at say 1m apart?
We have a holly JC in our garden for the past 5 years (see photo). The bulk of branches are low to the ground and more sparse mid and top of the shrub. The leaves are also being eaten by pests. Is it too late for me to prune the lower branches and any ideas on pest control. There are pieces of leaves missing as a clue.
I inherited this tree in a pot with the house.It had 2 leaves at first but has added some in the last 2 years.Can you tell me what it is?
I'm wondering what the best hedge would be for screening? I've been thinking of Laurels, but believe they're an invasive species? I'm looking for something affordable and hardy & evergreen. In addition, I want to get this done ASAP so something that can be planted year round (or late Spring). It's for a border area of approx 5ft depth.
I have to train a large Virginia creeper up a wall but I can't screw anything into the wall as it is hollow (I think it's externally insulated). Is there any clever method for attaching something to the wall that the climber can then use?
Why would an Aucuba japonica suddenly begin to wilt? It has been in place for a few years. The leaves have what looks like wind damage also.
I planted a Elaeagnus x ebbingei hedge 2 years ago. It has always had these insects on it and I kept them at bay by individually washing the leaves. But now it is too big and is suffering badly! There are about 16 plants and all affected. Myrtles in between are fine. Leaves have yellow patches on upper side and grey/ black powder on underside. Insects also on underside. White waxy stringy deposits on tips of branches during summer.
My Magnolia has a central stem with rot. Should I go extreme and prune it hard to save the plant? I noticed an earwig in the hole last year too.
I planted photinia hedge spring 2013. I probably plante half and then finished it 2 months or more later!! so the second half of the hedge didn't get as good a start unfortunately. I have pruned it well twice yearly since to thicken it well. The good half is beautifully thick but the other half is weak and lower 🙁 I will feed it now with shrub feed but when pruning in April/may will i prune the weaker side harder to promote more vigorous growthwill it ever catch up??
I'm planning planting some Laurel and was wondering what sort of nutrient or fertiliser I should use - I'm told lime and some moss peat is good.
