Line of Trees for Screening
I know screening is a common question on the forum and I have found the previous posts interesting (I have used some ideas in this post) although I couldn't see any posts that specifically ask about a line of trees.
The construction of a new housing development has begun that will wrap around the side and rear of our garden, and we would like to screen against it. The access road will run tight by the side and rear of the garden and the houses that will overlook us will be three storey. The developers are planning to add in four or five trees across the bottom of the garden just over our fence - no detail on the type of trees that will be planted although we presume silver birch or similar.
Our main concern is getting some height and coverage down the full length of the side fence, ideally with trees so we don't give up too much width at ground level. We were thinking of a line of trees. The length is over 11m, from the bench to the end of the garden. We're happy to relocate any of the existing red robins and fig tree if needed.
The preference is for evergreen trees but not leylandii / conifers.
I have been considering a mixed line of Japanese Privet, Viburnum, Mop Head Maple, and Magnolia Grandiflora, all as full standard or pleached variety.
The spacing of each to be 1.2-1.5m probably more for the magnolia. It seems the Japanese Privet and Vibernum wouldn't have an issue at spacing around 1.2m.
We don't want to wait for trees to grow to give us this coverage, as even the building activity is intrusive so the quicker we can get some privacy back the better! As such I had thought I would purchase trees already at 3m+ height, around £350 a tree. The Magnolia would be around £500. Magnolia's around here seem to do well (North Surrey), there are good, established trees in many gardens.
In total around 8 trees.
I would be grateful for any thoughts on the project. I have seen recommendations for Barchum Trees, Paramont Trees also come a lot on google searches, has anyone had any experience of them?
