Hi, we have an established Chilean Myrtle (Amonyrtus Luma) in our garden next to a south east facing wall. It is about 12ft tall but has had a tall shrub growing next to it which has now been removed. As a result the tree’s main growth and foliage is slightly to one side and at the top of the branches. Please can you advise whether it is possible to prune the existing branches withouty killing the tree and would this encourage further growth? many thanks Robin Cooper
Generally, any hard pruning should be done to this tree while it is young. The tree can handle pruning of no more than 1/3 of the shrub at a time. You may do this once every two or three months to control height, but it will halt fruiting for up to 2 years!
This article will offer more information on the care of the tree:
