Pruning houseplants is meant to control growth of the houseplants, rejuvenate growth and keep the houseplant neat and attractive. The various activities involved in pruning are important and they vary from houseplant to houseplant. It is important to understand which activity is approprate for the particular houseplant. The three major pruning activities are pinching out (stopping), cutting back and trimming.
This is the removal of the growing tips. It can be done by snipping off the growing tips with the thumb and forefinger or clean scissors can be used to do so. The main purpose of pinching is to encourage branching to produce a more bushy and compact houseplant. It should be done when the plant is actively growing and the stem should have at least three leaves. Always pinch above a node; the point where the leaf is attached to the stem to encourage branching to occur below the cut.
This involves more extensive cutting out of excessive growth by use of secateurs, scissors or a knife. Cut out dead and diseased stems, crowded stems and all-green shoots on variegated houseplants. Cut back over-long branches and old leafless stems. Always make clean cuts at an angle of 450 and also avoid tearing the stems to minimize accumulation of water in the wound which can lead to fungal infection.
This is the removal of dead leaves, damaged parts and faded flowers. This ensures the houseplant remains neat, clean and attractive and also minimizes pests and disease infestation. Trimming dead flowers (dead-heading) will prolong the flowering period of many species.
Note: Never guess with pruning; some houseplants will fail to bloom if pruned, others will become overgrown and unattractive if not pruned. For houseplant specific pruning requirements, look it up in this Houseplants A-Z Guide.
