White Sapote

White Sapote

Casimiroa edulis


These seeds should be planted immediately - do not store them

Getting started -- Brush the seeds under running water to remove any mold that may have formed during shipping.  Next soak the seeds in a cup of water for 2-4 hours, but no more than 6 hours.

Soil -- White Sapote likes well-draining soil.  A good mix would be 2 parts high-quality potting soil, 1 part horticultural sand, and 1 part perlite (or pumice rock).  Do not add lime to the mix, as the plant prefers slightly acid soil. 

Start the seeds in individual containers 8" tall or more (20 cm).  Plant the seeds 1" deep (3 cm) and water the soil until evenly moist.

The best temperature for germination is about 70-80 F (22-27C) day and night.  Ensure that the soil remains evenly moist (but not soggy).

They should begin sprouting after 4 weeks, but allow up to 10 weeks for any slow ones.  Once they sprout, give them filtered sunlight or morning sun.  Avoid strong afternoon sun the first 2 months.

Repotting -- When the plants are almost the height of the pot, it is probably time to repot them to a deeper pot.  When the roots begin circling the bottom of the new pot, repot again to a larger/taller pot, or into the ground, in suitable climates.  If you keep it in a pot, the final pot size will depend on how large you let the plant grow, but a minimum of 15 gallons (60 liters) is recommended.

Climate -- The White Sapote is happiest in slightly cooler conditions than most citrus prefer.  It has been grown successfully in warmer areas like Florida and Arizona, but consider it experimental in areas that regularly get above the low 90s (34C), particularly if nights are warm. Mature trees can take occasional drops to 22 F (-6C), but young trees should be protected from frost the first 3 years.

It likes part sun to full sun. Some afternoon shade might be needed in hotter areas.  It enjoys regular watering and feeding, especially during periods of fast growth.  You may use a citrus fertilizer for this plant.

Pruning --  Seedlings go through a period of fast, tall growth the first few years.  If they grow too tall, simply cut them back and s. 

Pests to watch for -- aphids, scale (brown or black disks on the stems).

By the way, it's normal for the plant to drop it's leaves briefly in late winter.

Good luck!
