trying to identify diseased bush and what will help

Question from barry

Quite sunny garden. I'm trying to identify this bush which on the inside of a garden wall (wall is around 4 ft in height) the bush gets sunshine all day. It appears to have a disease so I'm trying to identify the bush and try and find out what I can do to bring the bush back to life, and how to feed the bush. Some parts of the bush appear to have died. The bush is only around 3 metres in length by around 1 metre width. It has other types of bushes on either end.

Question from Shannon Rutledge

Is mid to late February too late to trim back my Crepe Myrtle? They have never been trimmed before & are quite tall & bushy. My neighbors say they are beautiful the way they are, they do bloom a bit late. They have large pink flowers.

Can I cut some roots of a Silver Birch tree without causing serious harm?

Question from Norman Read

I have to widen the surround of a long, narrow pond near a mature silver birch tree (betula utilis jaquemontii). The roots of the silverbirch seem to have found their way round the original pond, and some go right up to the edge where I have to work, at one point this is only about a metre from the tree.
If I cut some of the small (say, less than 15mm diameter) roots to make space for the widened foundation, will it seriously affect the tree, or will it just sprout new roots?
Second question:
I have tried digging carefully round the roots, removing soil and lowering the roots. Will the tree tolerate this treatment?

Shrubs with a white colour theme?

Question from Robert Lawrence

Can anyone help us please?

We are seriously looking to change one of our main borders from herbaceous perennials to a shrub border with a main colour theme of white, whether in flower or in variegated foliage. This takes me out of an area of which I am modestly comfortable to an unknown!

I'm wondering if any member would care to give us their suggestions and as we are going to buy the shrubs, seems logical if we could buy them from a member as well?

I have attached more information on soil type, position, our first stab at a list and a photo of the border

Thanks for reading.

Advice on clear stem trees

Question from Rose

Could anyone offer advice on suitable evergreen clear stem trees that offer privacy of at least 3.5 meters to be planted along the property boundary. My garden is drenched in sunshine all day long.
I live in a coastal area with clay soil.
I had thought Ligustrum Japonicum but have been told they don’t look very attractive.
I do like the look of olive trees but they are very expensive when brought at a ready height of 2meters plus!
I wouldn’t mind mixing a few trees to give interest.
Ideally I would like to be able to maintain a floral bed underneath.
Any help or suggestions would be much appreciated

Can anyone Identify this Spruce Tree please

Question from mark

Originally thought this was a blue spruce but now I'm not sure. I need to identify this tree as it sits within 10 meters of the main house, therefore need to estimate a mature height to the tree.

Thuja Plicata Atrovirens or Thuja Plicata Martin

Question from khurm chaudry

I am looking for privacy trees, as I have some flats overlooking my back garden.

I have narrowed the trees I want to either 1) Thuja Plicata Atrovirens or 2) Thuja Plicata Martin, but am confused on which of these to go for. I would like answers to my questions below to decide.

Questions:
1) Which of these is the quickest growing?
2) What is the maximum height each of these trees can reach?
3) Keen to avoid cleaning leaves and trees waste. Do shred bark or cones?
4) How many trees would I need to plant to cover 17m?

I would greatly appreciate some advice.

Prunus Subhirtella Pendula - Weeping Cherry

Question from Sue Bolton

My daughter has bought a weeping cherry - prunus subhirtella pendula for her garden. She wants to grow it in a large container beneath a sturdy wooden pergola with the branches trailing down over the top of the pergola. It’s approx 10 ft in height. The garden centre she bought it from have said that it won’t grow too much taller than its current height in the next 5 - 10 years and will be fine in a container provided it’s kept watered. I’m unsure whether it will be ok in a container or it should be planted in the ground. Any suggestions welcome.
