We recommend using the following to sow the seeds:
Plant these seeds on the surface of well draining planting medium consisting of peat, perlite, and sand. Place them in a bright and warm spot(at least 70F). Placing a plastic covering over the seeds until they sprout helps maintain a good humidity and warmth level- it can be removed once the sprouts start to show up.
Most seeds will germinate within a week, but wait some time for all the seeds to germinate- there may be some stragglers! Make sure the sprouts don’t receive much direct sunlight for the first couple of months, after which they can be exposed gradually to more light.

These seeds are for the 2026 growing season.
