Watering. Water regularly to keep the soil moist but not soggy. Allow the top inch of soil to dry out between waterings to prevent root rot.
Fertilizing. Feed mandevilla every 2-4 weeks during the growing season with a balanced, water-soluble fertilizer to encourage healthy growth and abundant flowers.
Mandevilla is a vigorous climbing plant that thrives in warm, sunny spots. It needs regular watering but should not sit in waterlogged soil. If conditions are too dry or cold, it may lose leaves or stop flowering. Regular pruning helps keep it healthy and encourages blooming.

Mandevilla plants can produce pollen that might cause mild allergic reactions in sensitive people, such as sneezing or itchy eyes. The sap can sometimes irritate the skin, so it's best to wear gloves when handling or pruning the plant. To reduce exposure, avoid touching the sap and keep the plant away from areas where people with allergies spend a lot of time.
Common problems
Overwatering can cause root rot, while underwatering leads to wilting leaves. Lack of sunlight may reduce flowering. Pests like aphids or spider mites can occasionally appear.
Uses
Primarily grown as an ornamental vine for its attractive flowers and climbing habit. Ideal for trellises, fences, and containers on patios or balconies.
Notes
Prune in early spring to control size and shape. Protect from frost as it is sensitive to cold temperatures. Repot every 2-3 years to refresh soil and encourage growth.
