Annona muricata, commonly known as soursop or graviola, is a tropical fruit tree native to the Caribbean and Central America, valued for its creamy, aromatic pulp. Seed propagation is the most common method, though germination can be erratic and slow. Proper pre-treatment with soaking and scarification significantly improves germination success rates.
Before sowing
Soaking in warm water for 24 hours and optional light mechanical scarification recommended to improve germination rates

Tips
Use fresh, plump seeds from ripe fruits for best results. Maintain consistent warmth (75-85°F/24-29°C) and high humidity (70-80%) using a humidity dome or plastic cover. Keep substrate moist like a wrung-out sponge, never waterlogged, to prevent fungal issues. Provide bright indirect light once seedlings emerge; avoid direct sunlight which can scorch tender leaves. Germination is variable, taking 2-8 weeks depending on seed quality and conditions. Change soaking water every 12 hours during pre-treatment to prevent bacterial growth. Transplant to individual containers when seedlings develop true leaves. Acclimate gradually to lower humidity and increased light before moving outdoors.
