Alstroemeria longistaminea - Germinating the seeds

 

Germinating the seeds

 

These seeds sprout best if placed in the refrigerator for 4 weeks, after an initial 3 weeks at room temperature. The tips below explain the process.

 First, soak the seeds in a cup of water for 24 hours.

 Use small pots or cups that have drainage holes.  Fill with a well-draining soil mix.  A typical mix is 2 parts potting soil to 1 part perlite.  An alternate mix is 3 parts perlite to 2 parts coir fiber. 

 Plant 1-2 seeds in each pot, about 1/4 inch (6 mm) deep.  Add water until the soil is evenly moist (but not saturated).

For the next 3 weeks, ensure that the soil stays moist.  Keep the pots between about 68 and 84 degrees F (20-29C). 

 After 3 weeks, enclose the pots in an airtight plastic container or bag and place in the refrigerator.  Ensure that the temperature stays above 35F (2C).

 After 4 weeks (mark your calendar) remove the pots from the container/bag, and keep them in an area that stays between about 65 and 85F (18-29C).

 Germination can occur over a long period, beginning any time after 4 weeks and continuing for up to 6 months.  Occasionally, some may take over 6 months, but most should sprout within 1 to 4 months.

 Once they sprout, give them bright light, with protection from strong afternoon sun.  Keep the soil evenly moist, and feed every 8-10 weeks months with a general-purpose fertilizer.

 You may transplant them to larger containers when the plants are 3 months old. Repot gently to avoid breaking apart the soil ball.  Water before transplanting, to keep the soil ball together.

Good luck!
