When to Plant Red Mandevilla Flowers

• Best Planting Time: Spring or early summer, when the weather is warm and stable.
• Ideal Temperature: Mandevilla thrives in temperatures above 60°F (15°C) and should not be exposed to frost.

Where to Plant Red Mandevilla Flowers

1. Sunlight Requirements

• Full sun (6–8 hours daily) is ideal for maximum blooming.
• Can tolerate partial shade, but flower production may be reduced.

2. Soil Conditions

• Prefers well-draining, nutrient-rich, slightly acidic soil (pH 5.5–6.5).
• A mix of garden soil, compost, and sand ensures good aeration and drainage.

3. Growing in Containers

• Choose a large pot (at least 12 inches deep and wide) with proper drainage holes.
• Great for patios, balconies, and bringing indoors in colder climates.

How to Plant Red Mandevilla Flowers

Planting in Garden Beds

1. Select a sunny location with well-drained soil.
2. Dig a hole twice the size of the root ball.
3. Place the plant in the hole and backfill with soil.
4. Water thoroughly to help establish roots.
5. Provide a trellis or support for climbing varieties.

Planting in Containers

1. Use a container with drainage holes.
2. Fill with a well-draining potting mix.
3. Place the plant in the container and press soil gently around it.
4. Water well and position in full sun.

How to Care for Red Mandevilla

1. Watering

• Keep soil moist but not waterlogged.
• Water deeply once or twice a week, allowing soil to dry slightly between waterings.
• Reduce watering in winter months when the plant is dormant.

2. Fertilizing

• Use a balanced liquid fertilizer every 2–3 weeks during the growing season.
• A high-phosphorus fertilizer (such as 10–30–10) encourages more blooms.

3. Pruning and Training

• Prune in early spring to remove dead or weak stems.
• Regular pruning encourages bushy, compact growth.
• Pinch off growing tips to promote side branching.

4. Pest and Disease Control

• Common Pests: Aphids, spider mites, and whiteflies (treat with neem oil or insecticidal soap).
• Diseases: Root rot (from overwatering) and powdery mildew (improve air circulation and avoid wet foliage).

Companion Plants for Red Mandevilla

Best Companion Plants

• Lantana: Shares similar sun and water needs while adding more color to the garden.
• Petunias: Provide a great contrast with their compact size and bright blooms.

• Jasmine: Complements Mandevilla’s climbing nature and fragrant blooms.
• Marigolds: Naturally deter pests while adding a bright color mix.

Plants to Avoid

Overwintering Red Mandevilla

• In colder regions (below 50°F/10°C), bring potted Mandevilla indoors before frost.
• Keep in a bright, warm spot with minimal watering.
• Cut back growth in winter to help the plant conserve energy.
• In spring, move back outside after frost risk is gone.

Common Problems and Solutions

1. Yellowing Leaves
