I have several potted angel trumpets that were rather neglected inside over the winter. Between lack of watering and a mite infestation, the plants had almost completely defoliated. I took them back outside a few weeks ago, sprayed, feed, and watered them, and now they are growing much foliage, and even a few flower buds already. But they are basically tall (~4') stalks with a small group of leaves and short branches at the very top, and the full length of the trunk covered with small shoots. My question is, should I prune out some of the shoots to allow the remaining branches to grow out better? If so, how many to prune out and how many to leave? I.e, should I prune off every other one, or leave every third one, etc.?
