How to Grow and Care for a Mandevilla Plant

1. Choosing the Right Location

Mandevilla plants love the sun! They require at least 6 hours of direct sunlight daily for healthy growth and abundant blooms.

Best locations for planting:
Balcony or Patio: Ideal for potted Mandevilla.
Garden Bed: Ensure well-draining soil.
Hanging Baskets: Use compact varieties for a cascading effect.

Avoid shady areas as they reduce flowering.

2. Soil Requirements

Mandevilla thrives in light, well-draining soil rich in organic matter.

Best Soil Mix for Mandevilla:

• 50% potting soil
• 25% perlite or sand for drainage
• 25% organic compost for nutrients

Tip: Use a slightly acidic soil (pH 6.0–6.5) to encourage healthy root development.

3. Watering Schedule

How often should you water Mandevilla?

• Spring & Summer: Water when the top 2 inches of soil are dry.
• Fall & Winter: Reduce watering to prevent root rot.

Pro Tip: Mandevilla dislikes soggy soil! Always ensure proper drainage in pots and garden beds.

4. Fertilizing for Maximum Blooms

Fertilizing is crucial for Mandevilla to maintain its vibrant flowers.

Use a balanced, water-soluble fertilizer (10-10-10 or 20-20-20) every two weeks during the growing season.
For more blooms, switch to a phosphorus-rich fertilizer (e.g., 10-30-10) in mid-summer.

Avoid over-fertilizing in winter, as Mandevilla goes dormant.

5. Pruning & Training Mandevilla

Why prune Mandevilla?

• Encourages bushier growth
• Helps control size and shape
• Removes dead or weak stems

Best Time to Prune:

• Early Spring (before new growth begins)
• Trim back one-third of the plant to maintain size.
• Remove yellowing leaves and dead blooms to keep the plant healthy.

Caution: Mandevilla produces a milky sap that can irritate the skin—wear gloves while pruning!

Overwintering Mandevilla: How to Keep It Alive in Cold Climates

How to Overwinter Mandevilla Indoors

Step 1: Before the first frost, prune back the plant by 50%.
Step 2: Move it to a bright, warm spot indoors (a south-facing window is ideal).
Step 3: Water sparingly (once every 2-3 weeks).
Step 4: Watch for pests like aphids and spider mites—treat with insecticidal soap if needed.
Step 5: In spring, slowly reintroduce the plant to outdoor conditions.

Pro Tip: If you don’t have indoor space, dig up the Mandevilla roots and store them in a cool, dry place.
