Repotting

Repot Blue Passionflower during the growing season only when the plant is extremely pot-bound; it blooms more when pot-bound. Do not repot a plant that is in flower. Use a pot 1 size larger and one that has a drainage hole to prevent waterlogging as it can lead to Root-rot Disease. The soil should be rich in organic matter and free-draining. Large plants can be top-dressed by replacing the top 3-4 in of soil with fresh soil.

Pruning

Pruning Blue Passionflower is easy. Remove dead flowers to maintain your plant neat and tidy. Pinch off the growing tips to encourage compact growth and prevent the plant from getting unruly. After flowering, cut back the stems to rejuvenate growth. Learn more on how to prune houseplants.
