Passiflora foetida may cause mild skin irritation in some people due to its sap. It produces pollen that can trigger allergies in sensitive individuals, especially during its flowering season. To reduce exposure, avoid direct contact with the plant's sap and wear gloves when handling it. Keep it away from areas where people with pollen allergies spend a lot of time.
Common problems
Overwatering can cause root rot. Poor air circulation or high humidity may lead to fungal diseases. Pests like aphids or spider mites can appear if the plant is stressed.
Uses
