Growing Aloe from Seed: Collecting, Sowing, and Seedling Care

Collecting Aloe Seeds

Plants must be 4+ years old to produce reliable seed. Seeds are tiny, grayish-brown to black, and flat. Light-colored seeds are immature. Harvest from brownish-green dried pods by splitting the pod over a basin.

Storing Seeds

Store in a paper envelope in a cool, dark place. Use within the harvest year for best results.

Sowing

• Medium: 1:1 peat and horticultural sand (or sand, sterile compost, perlite). Must be well-draining and pathogen-free.
• Container: Flats use less soil and create a controlled environment.
• Sowing: Lightly dampen medium; spread seeds ~1 inch apart; cover with a light dusting of sand.
• Temperature: Ideal 75°F (23°C). Use bottom heat if not in a warm climate.
• Humidity: Many use a plastic lid or bag, but non-sterile organic media can cause fungal issues.

Seedling Care

• Mist surface until sprouts appear (2–4 weeks).
• Keep on heat source for 2 weeks while roots develop.
• Water from below to prevent damping off.
• At 4+ leaves, transplant to 2-inch pots with sterilized mix: 3 parts organic, 3 parts pumice, 1.5 parts coarse sand.
• Grow on as adult plants.
