Soursop Indoor Growth And Pruning

Question

Hello I grew a Soursop (guanadana) tree from seed, indoor, for 3 years now. The tree is very big (2.5 m) with the top bending when touching the ceiling 🙂 It s in a 40 L container. I m wondering if i should and how to prune it , I m a bit weary of cutting branches (what shape to give ? ) Ps. I live in southern France, it s hot but not enough to grow it outside , occasional freezing temperature are still possible in winter.

With, occasional, pruning of the top and root pruning, you can keep this manageable in container. You may prune to your desired height, but it is best not to take more than 1/3 of the whole tree at one time. I would cut it back by 1/3, and cut out some of the larger roots and repot. Try not to break all of the finer roots when doing so. It is ok to lose anchor roots, but the finer roots feed the tree. Try and keep a good portion of them intact. Make sure that your tools are sanitary to avoid causing disease. Once you establish the first pruning, all others will be easier, and you may not even need to do a hard pruning again.
