Princess flower is generally tolerant of limited water and may become mildewy with too much water. Right after pruning is a good time to water and fertilizer though, to encourage new growth and blooming. However, care needs to be taken to avoid wounded areas when watering to avoid fungal infestation of the plant through fresh wounds. When you are ready to dispose of sections of the plant that you removed during pruning, there are two important things to keep in mind. Princess flower leaves or branches found to be diseased need to be trimmed off and destroyed away from the plant. Do not use it as compost material. Wherever you dispose of the trimmings, remember that Princess flower roots and spreads easily. Be careful that your trimmings do not inadvertently produce new, unwanted Princess flower.
