Starting Seeds Indoors

For indoor seeds, start sowing 4-6 weeks before the last frost date of your area. Soak the seeds overnight to help them germinate faster. Place them in a seed-starting mix soil mixture and keep them in a warm and dark place with sufficient moisture.

Transplanting Seedlings to Outdoor Containers or Garden Beds
