House plants are often tropical or sub tropical plants specially adapted to growth inside the home. They have basic requirements: a modicum of light, lots of water, fertilizer and good potting soil. On occasion--and with certain varieties--regular trimming is required. Trimming trains the plant to grow and improves the appearance of the plant. A properly trained house plant is compact with dense foliage. Frequent trimming will achieve this.
Locate branches that are long or overgrown and find the new growth at the end of the branch.
Gently grasp the branch by the stem near a leaf joint, and gently pinch and twist the growth until it comes off. Pinching at a leaf node promotes side growth.
Prune away dead or diseased branches from the plant, cutting back the branch at a leaf node using a pair of sharp, clean pruning shears. Cut at a slight angle to keep the cut clean. Wipe the pruning shears with alcohol before each cut to prevent spreading disease.
Remove dead flower buds from a house plant, cutting it at the node to encourage new flower growth.
