Acca sellowiana, commonly known as pineapple guava or feijoa, is an evergreen subtropical shrub native to the highlands of South America, belonging to the Myrtaceae family. Seed propagation is straightforward and reliable, though resulting plants may not be true-to-type due to cross-pollination. Seeds are positive photoblastic and require light, consistent moisture, and warm temperatures for optimal germination.
Before sowing
Extract seeds from ripe fruit and ferment in water for 4 days, then rinse and dry before sowing; seeds remain viable for 1+ year if kept dry

What to expect
Tips
Seeds are positive photoblastic; keep under light conditions. Maintain high humidity with a clear plastic bag or covered propagator; open occasionally for air circulation to prevent mold. Keep soil consistently moist but not waterlogged. Use bottom heat (20-25°C) with cooler nights for better results. Avoid over-watering. Prick out seedlings into individual pots when large enough to handle. Grow on in a greenhouse for at least the first winter before hardening off. Seeds retain viability for over a year when dried and stored properly. For specific cultivars and guaranteed fruiting characteristics, use semi-ripe cuttings taken in summer.
