What Is a Mandevilla?
Mandevilla, also known as rocktrumpet, is a tropical and subtropical flowering vine native to South and Central America. It belongs to the dogbane family (Apocynaceae) and is prized for its glossy leaves and large trumpet-shaped flowers that come in shades of pink, red, white, and yellow.
Because of its climbing nature, Mandevilla is often grown on trellises, fences, or hanging baskets where the vines can gracefully trail or twine. It’s perfect for adding instant color and tropical flair to patios and garden corners.
Ideal Growing Conditions Of Mandevilla
To grow Mandevilla successfully, you’ll need to recreate its natural warm and sunny habitat.
1. Light of Mandevilla:
Mandevilla thrives in bright, indirect sunlight. It loves at least 6 hours of sun daily, especially morning sunlight. However, in very hot regions, it appreciates some afternoon shade to protect its leaves from scorching.
2. Temperature of Mandevilla:
Being a tropical plant, Mandevilla prefers warm temperatures (above 15°C or 60°F). It’s not frost-tolerant and should be brought indoors or protected during cold months.
3. Soil of Mandevilla:
Use well-draining, slightly acidic soil. A mix of garden soil, peat moss, and perlite or sand works perfectly. Good drainage is essential because soggy roots can lead to rot.
4. Humidity of Mandevilla:
Mandevilla loves high humidity, so misting the leaves occasionally or placing a humidity tray nearby helps, especially if you’re growing it indoors.
Watering Tips Of Mandevilla
Mandevilla enjoys consistent moisture but dislikes waterlogging.
- During active growth (spring and summer): Water regularly to keep the soil evenly moist but not soggy.
- In winter: Reduce watering since the plant’s growth slows down. Allow the top inch of soil to dry out before watering again.
Always ensure the pot has drainage holes to prevent root rot.

Feeding and Fertilizing Of Mandevilla
For healthy foliage and abundant flowers, feed your Mandevilla regularly.
- Use a balanced, water-soluble fertilizer (10-10-10 or 20-20-20) every 2–3 weeks during the growing season.
- Once the plant starts blooming, switch to a phosphorus-rich fertilizer (like 10-20-10) to encourage more flowers.
- Stop fertilizing during the dormant period in winter.
Pruning and Training Of Mandevilla
Mandevilla vines can grow quite vigorously, so pruning keeps them in shape and encourages new blooms.
- When to prune: Late winter or early spring, before new growth begins.
- How to prune: Cut back overgrown or weak stems to promote branching.
- Pinch off the growing tips occasionally to encourage bushier growth.
If you’re growing it on a trellis, guide the vines early to create an attractive shape.
Propagation Made Easy Of Mandevilla
Mandevilla can be propagated through stem cuttings.
Steps:
- Take a 4–6 inch cutting from a healthy stem in spring or early summer.
- Remove the lower leaves, leaving just a few at the top.
- Dip the cut end in rooting hormone.
- Plant it in a pot filled with a mix of sand and peat moss.
- Keep the soil moist and cover the pot with a plastic bag to retain humidity.
Roots usually develop within a few weeks, and you’ll have a brand-new Mandevilla ready to thrive!

Overwintering Mandevilla
In cooler climates, Mandevilla needs protection from frost.
- Before the first frost, bring potted plants indoors.
- Place them near a sunny window and reduce watering.
- If growing outdoors, you can cut back the vines and store the plant in a cool, frost-free area until spring.
In spring, move it back outside gradually once temperatures rise above 15°C (60°F).
