Spring is the best time to prune and annual pruning will keep it dense and thick rather than leggy where all the foliage is at the branch tips. You can prune your oleander back by about a third without harming the plant. Pruning will force growth towards the inner branches as well as the tips of the branches. If you want to reduce the size of your 20 year old oleander, you can prune it down over a 2-3 year period. Try not to remove more than one third of the growth when you prune, and be sure to prune the stems at varying lengths so it has a more natural look. Just lopping off the top or the sides will make it look odd when it regrows. Best wishes with your project!
