Insert a plant stake into the soil near the base of the plant, using care not to injure the roots. For houseplants, a wooden dowel may provide enough support, but for those grown in the soil, a wooden or metal garden stake may be needed. The stake used should support the weight of the plant without tipping or wiggling.
Tie the main stem of the plant loosely to the stake with soft plant ties. Strips of fabric or old pantyhose make effective plant ties that will stretch as the plant grows. This avoids injuries to the main stem of the plant while providing the support it needs.
Move the plant to the appropriate lighting to encourage healthy growth. For outside plants, eliminate any sources of shading that may prohibit the plant from receiving adequate light. Cutting back shrubs or trimming overhanging branches from trees to allow light to reach the plant may be enough to spur healthy growth.
