Answer: You can wait and hope, but severe pruning can kill a plant. We generally recommend you not remove more than one-third of the live growth of any plant in any pruning session. The roots need the benefit of foliage for photosynthesis and taking off too much at one time can halt this process. Leptospermum usually won't produce new growth from bare wood, so it's never a good idea to prune them all the way down. In fact, when old shrubs become overgrown or bare at the base, they're usually limbed up into small trees. At this point you might want to seriously consider replacements for your tea trees.
