  • How much to use

    Starting from seeds:

    • Fill a shallow container with Espoma Organic Seed Starter. Peat pots or special seed starting trays with drainage holes make transplanting easier.
    • Wet seeds and allow to drain.
    • Plant seeds according to package directions.
    • Place container in a warm bright location (avoid direct sunlight).
    • Keep moist by misting with a spray bottle.
    • When the plant develops its first true leaves transplant it into a larger container or outdoors in a prepared bed.

    Note: Dig seedling out of its mix and extend handle with care to avoid damaging the fragile stem and root system.

    Starting from Cuttings:

    • Add seed starter to a clean container and wet the mix.
    • Make a hole with a pencil, gently insert the cutting and pat the soil to close the hole.
    • Keep soil moist until roots are developed and the plant can be transplanted.
