Quick Tips for Success
Use Seed Starting Mix
Opt for a light, moisture-retaining soil mix, such as Burpee Organic Seed Starting Mix. It's designed to hold water without getting too heavy for roots to push through. Plus, it's enriched with plant food to give seedlings the nutrients they need to grow strong!
Water Evenly and Consistently
Your seeds need even moisture to germinate and grow. With too little water, they may not sprout. If oversaturated in soggy soil, they may rot from "damping off" disease. Check soil frequently to make sure it is not too wet and not too dry! Our SuperSeed™ tray is designed to retain water better than standard trays. Molded corner clots in each cell and deep channels in the watering tray also allow for better drainage and airflow, which helps prevent disease.
Transplant at the Right Time
Once you've patiently grown and tended to your seedlings, wait to plant them outdoors until all danger of frost has passed. The SuperSeed™ tray's flexible food-grade silicone cells gently pop out, so you can transplant seedlings without damaging roots. Always acclimate your seedlings to outdoor weather before you transplant. Start by setting plants outside in a protected spot for a few hours at a time, building up their time outdoors over the course of a week.
