Care Guide

Passifloraceae plants are generally easy to care for, and they can thrive in a variety of growing conditions.

Common Pests & Diseases

Passifloraceae plants are susceptible to a few pests and diseases, including:- Spider mites: These tiny pests can suck the sap from the leaves and cause yellowing and wilting.

Use a horticultural oil to control them.- Fusarium wilt: This fungal disease can cause wilting, yellowing, and death of the plant. There is no cure, so prevention is key. Avoid overwatering and use sterile soil.
