Burpee SuperSeed Windowsill Seed Starting Tray – 8 XL Cells, Reusable & Dishwasher Safe

A compact seed starter for windowsill gardens

The Burpee SuperSeed Windowsill Seed Starting Tray brings the joy of seed propagation to a sunny corner of your home. With eight extra‑large, flexible cells, it provides generous space for developing roots while staying slim enough for a bright windowsill. The design supports vegetables, herbs, and flowers, offering a practical, space‑savvy solution for indoor germination that adapts to your growing space.

Smart design that supports healthier seedlings

Soft food‑grade silicone cradles each seedling and flexes slightly to pop out with minimal root disturbance when it’s time to transplant. This gentleness helps reduce stress on young plants as they move to pots or outdoor beds. Corner drainage slots promote soil aeration, while the deep channels in the watering tray pull excess moisture away from the roots. A raised perimeter edge keeps water contained in the tray, helping minimize spills during daily care.

Convenient, reusable, and easy to maintain

Thoughtful touches make everyday use easier: side handles for lifting, a Plant‑o‑Gram diagram for quick seed tracking, and alphanumeric row labels to identify each tabulation at a glance. After transplanting, the tray cleans up quickly and can be reused for the next season. It is top‑shelf dishwasher safe, turning cleanup into a simple step rather than a chore.

Seasonal timing and practical tips

Many favorite vegetables begin indoors before outdoor warmth arrives. Start pepper seeds 8–10 weeks before your area’s average last frost and tomato seeds 6–8 weeks prior. Check each Burpee seed packet for variety‑specific timing and planting instructions to align with your climate and schedule.
