When To Prune A Bottle Brush Plant
Bottlebrush plants flower on the current years grows so lightly prune just after the bush has finished flowering to keep them under control, cutting just behind the spent flowerhead. Most bottlebrush do not take kindly to being hard-pruned, although C citrinus ‘Splendens’ can be cut more severely if needed, and this is also best attempted immediately after flowering.
Feeding with a high potash feed such as liquid tomato feed will help encourage flowering. In the case in which you have had to cut back your bottle brush by more than a third to control the size start feeding with a high nitrate fertilizer to encourage new stem growth.
