✨ GROWING GUIDE – Miracle Fruits (Synsepalum dulcificum)

✨ Miracle Fruit (Synsepalum dulcificum)

Magical berries that transform acidity into sweetness for 30-60 minutes.

The miracle fruit contains a protein (miraculin) that temporarily changes the perception of sour taste into sweet taste.


☀️ Light

Bright, indirect light in partial shade. Avoid direct, scorching sunlight. Ideal near an east- or west-facing window with a curtain.

💧 Watering

Keep the soil consistently slightly moist. Use soft water (rainwater or filtered water). Sensitive to limescale.

🌡️ Temperature

Ideal: 20-27°C. Minimum: 15°C. Prefers high humidity (60-70%). Houseplant in Quebec.

🌱 Fertilization

Fertilize acid-loving plants (like azaleas) every 3-4 weeks in spring and summer. Avoid lime-based fertilizers.

🪴 Repotting

Every 2 years in spring. Acidic potting soil (pH 4.5-5.8), such as ericaceous compost. Excellent drainage is essential.

✂️ Size

Prune lightly to maintain a compact shape. Pinch back young shoots to encourage branching.

🐛 Common problems

  • Yellow leaves: Hard water or pH too high
  • Slow growth: Normal, slow-growing plant
  • Scale insects: Treat with insecticidal soap

✨ Fruiting

Can produce from 2-3 years old. Small, oblong red berries. Chew the pulp for 30 seconds, then taste a lemon: it will be sweet!


Tropico-Québec tip: Use only non-calcareous water and acidic potting soil. The miracle fruit is very sensitive to lime.
