Annona reticulata, commonly known as custard apple or bullock's heart, is a small tropical deciduous or semi-evergreen tree native to the West Indies. Seeds exhibit natural dormancy and low to medium germination rates, requiring proper seed treatment to improve emergence. Consistent warmth, humidity, and light are essential for successful seedling establishment.
Before sowing
Use high-quality, light, porous, well-draining pathogen-free substrate such as perlite, vermiculite, or peat moss mix

What to expect
Tips
Seed scarification is critical—lightly scratch the seed coat or make a small incision at the hilum before soaking. Use warm water (60°C) for faster dormancy breaking. Fresh seeds germinate better than old seeds. Maintain constant moisture without waterlogging. Germination may take 2-7 months, so patience is required. Once seedlings emerge, provide bright, indirect light and acclimate to full sunlight gradually before transplanting. Keep substrate warm (75-85°F) during germination period.
