Thank you all for your responses , very helpful. We are looking for a bare trunk and then about 1-1.5 meters above the wall and don’t want the look of a more formal hedge. The pleaching trees and holly both look like they are suitable. We definitely don’t want conifers!
Hello I’m new to this forum and would welcome advice on planting some new trees. We have a garden wall which is just under 2 meters high and are looking for 1 or 2 trees to plant against this wall for further privacy above wall level. Ideally we need trees with fairly narrow and tall (around 1.8m) trunks as we have limited garden area. The trunks would then be against the wall with the crown of the trees above the wall. We would like evergreen trees that are slow/medium rate for growth (cutting back perhaps once a year). Looking at either 1 tree if the spread of the foliage will be quite wide (around 2 meters) or 2 trees if narrower spread. All suggestions welcome. Thanks in advance. Emma
