Keep the seed-starting medium moist but never waterlogged.
-
Give young seedlings partial shade, then gradually introduce more direct sunlight.
-
Choose a permanent location with good drainage and plenty of room for growth.
Seed Storage
Ackee seeds are recalcitrant, meaning they do not tolerate drying and long-term conventional seed storage well. For the best chance of germination, sow fresh seeds as soon as possible after collection. Avoid sealing wet seeds in an airtight container for extended periods, and follow the supplier's instructions for any short-term transport or holding.
