Mandevilla Live Tropical Houseplant Care: Medium
Watering: Water mandevilla 1–2 times a week, increasing to daily during very hot periods. Allow the top inch of soil to dry between waterings. Avoid standing water, as it can lead to root rot.
Light: Requires at least six hours of sunlight daily. Can tolerate some shade, but bright, indirect light is ideal. Protect from harsh afternoon sun to prevent leaf scorch.
Soil/Drainage: Grows best in sandy, well-draining soil with a pH between 6.6 and 7.8. Enhance drainage by mixing in compost or other organic matter.
Temperature: Prefers warm conditions, ideally 70–90°F (21–32°C) during the day and around 60–65°F (15–18°C) at night. Bring indoors if there’s a risk of frost, as hard freezes are fatal.
Humidity: Enjoys high humidity. Mist the leaves regularly or use a humidifier if growing in a dry climate.
Fertilizing: Feed in spring with a phosphorus-rich fertilizer. During the blooming season, apply a half-strength liquid fertilizer every two weeks to support flowering.
Pruning/Support: Provide a sturdy trellis or support for climbing. Prune to maintain shape and remove dead or weak growth, promoting a healthier, more attractive plant.
Pests and Diseases: Watch for spider mites and avoid keeping the soil too wet to prevent fungal diseases. Improve air circulation and maintain proper watering practices to keep the plant healthy.
Repotting: Repot when the plant becomes root-bound, choosing a slightly larger pot. Ensure good drainage to encourage strong growth and abundant blooms.
