How To Grow Mandevilla: A Step-By-Step Guide
For any gardener, growing Mandevilla is a wonderful experience. Its vivid, eye-catching blooms and verdant leaves can give your yard a touch of the tropics.
Here’s a step-by-step guide to help you grow Mandevilla successfully:
1. Choose The Right Location
Mandevillas thrive in full sun and require at least 6 hours of direct sunlight daily.
To get optimal sunlight, plant them near south-facing walls or trellises. Sunlight enhances flower production and overall growth. Avoid shaded spots, as they hinder blooming and lead to weaker growth, diminishing the plant's health.
2. Prepare The Soil
Mandevillas prefers well-drained, loamy soil with a slightly acidic pH of 6.0–6.5. Add compost to the soil to enhance drainage while planting in the ground.
Avoid compacted or clay-heavy soils, as they retain too much water and risk root rot. Well-drained soil helps promote healthy root growth and optimal nutrient absorption.
3. Planting Mandevilla
To plant Mandevilla, choose well-draining soil and a sunny location. Dig a hole twice as big and as deep as the root ball.
Place the plant at the root ball's top level with the soil surface. Fill the hole, pat down gently, and water thoroughly to promote healthy root establishment.
4. Watering Needs
Mandevillas need consistent moisture, especially during warmer months. Water deeply when the top inch of soil is dry, but ensure the soil drains well. Root rot can result from overwatering.
Water the plant base to maintain balanced hydration, keep the leaves dry, and lower the chance of fungal illnesses.
5. Support The Vines
As a climbing vine, mandevilla requires support like a trellis, fence, or arbour. Install the support structure early and gently secure the vines using soft plant ties.
Early support helps direct the plant's growth, ensuring it climbs appropriately and avoids tangling while improving its aesthetics.
6. Fertilize Regularly
Mandevillas are heavy feeders and need regular fertilizing. Use a balanced, water-soluble fertilizer every 4-6 weeks during the growing season.
Blooming is encouraged by fertilizers with a larger middle number, such as 10-20-10. Avoid excess nitrogen, which promotes foliage growth at the expense of flowers. Regular fertilizing supports healthy growth and vibrant blooms.
7. Prune For Health And Shape
Pruning is essential for Mandevillas to maintain their shape and promote new growth.
In early spring, cut back leggy stems and remove dead wood. Avoid pruning too much from the main stems, as this could reduce the plant’s ability to produce flowers.
8. Protect From Frost
Mandevillas are frost-sensitive and should be protected from cold temperatures. If living in colder climates, bring the plant indoors before the frost arrives or cover it with frost cloths.
Keep it in a bright area with temperatures between 60°F–80°F (15°C–27°C) to avoid frost damage and ensure the plant's survival through winter.
9. Repotting Container Plants
If your Mandevilla is in a container, repot it every 1-2 years to allow for growth. Choose a larger pot (1-2 inches wider) with suitable drainage holes.
Refresh the soil using a mix of potting soil and compost for improved nutrition and drainage. Proper repotting ensures the plant has enough room for root expansion.
10. Mulching For Moisture Retention
Cover the base of your mandevilla with two to three inches of natural mulch, like wood chips or bark. Mulch helps maintain soil moisture, keeping the roots cool during hot weather.
It also reduces watering frequency and suppresses weeds, allowing plants to thrive without competition for nutrients.
11. Consider Companion Plants
When learning how to grow Mandevilla, consider pairing it with companion plants like lantanas, petunias, or geraniums that share similar sunlight and soil preferences for a harmonious garden.
These plants thrive in similar conditions, such as full sun and well-drained soil. Pairing plants with compatible needs creates a harmonious garden where all plants can grow without competing for resources or nutrients.
12. Controlling Mandevilla's Growth
If the Mandevilla grows too fast or becomes leggy, pinch back the tips of its stems. This encourages bushier growth and prevents the plant from becoming unruly.
Regular trimming keeps the Mandevilla neat, especially in smaller spaces or containers, where its sprawling nature can be challenging to manage without intervention.
13. Enhancing Flower Colour
Ensure the plant receives ample sunlight, which brings out vibrant hues to intensify the colour of Mandevilla flowers.
Avoid overfertilizing with high-nitrogen fertilizers, which might cause flowers to suffer from excessive leaf development. Balanced light and nutrient exposure encourage bright, colourful blooms throughout the growing season.
14. Dealing With Yellowing Leaves
Yellowing leaves on your mandevilla could signal overwatering, underwatering, or nutrient deficiencies. Check soil moisture and ensure proper drainage.
If the problem is nutritional, a small amount of balanced fertilizer may be helpful. Regularly inspect leaves for pests or diseases, which can also cause yellowing and affect overall plant health.
15. Avoiding Root Rot
To avoid root rot when growing Mandevilla, ensure it's planted in well-draining soil and use containers with proper drainage holes.
Proper drainage is essential to avoid water buildup around the roots, which can cause damage and illness. This applies whether the plant is grown in the ground or in pots.
16. Overwintering Mandevillas Indoors
Mandevilla can be grown indoors by placing it near a sunny window, watering it less frequently, and avoiding extreme temperature changes to keep it healthy throughout the winter.
Avoid drastic temperature fluctuations to minimize stress. Ensure the plant receives adequate sunlight to prevent it from becoming leggy or losing leaves during winter.
17. Mandevilla Disease & Pest Control
Aphids
Symptoms
Aphids cause yellowing of leaves, a sticky residue (honeydew) on the surface, and curled distorted growth. They are small, soft-bodied insects that feed on plant sap, weakening it.
Cause
Aphids extract sap from the plant, depriving it of nutrients. As they feed, they also introduce harmful viruses and diseases, weakening the plant’s health.
Treatment
Neem oil or insecticidal soap can eradicate aphids. These products dissolve the insect's exoskeleton, lowering its population and stopping additional plant damage.
Spider Mites
Symptoms
Spider mites cause yellow or brown spots on leaves and fine webbing between them. As the mites feed on the plant's sap, affected leaves may appear stippled or bronzed.
Cause
Dry, dusty conditions and poor air circulation create a favourable environment for spider mites. They flourish in hot, dry environments and can proliferate swiftly, harming plants.
Treatment
To control spider mites, spray the plant with water or insecticidal soap, focusing on the undersides of the leaves. Increasing humidity and improving air circulation can also deter mite infestations.
