Biodegradable Seed Starting Containers – CowPots® #4 Square

Eco-friendly seed pots for healthy transplants and sustainable gardening.

The CowPots® #4 Square Seed Starting Containers are the ideal choice for gardeners who want to nurture strong seedlings while reducing plastic waste. Made from 100% renewable cow manure fibers, these biodegradable pots provide ample room for root growth and naturally enrich the soil as they break down after transplanting.

Designed with a taller profile, these pots are perfect for crops like tomatoes, peppers, and eggplants that need extended greenhouse time before moving outdoors. Simply plant the entire pot directly into the ground—roots grow through the decomposing fibers, minimizing transplant shock and promoting healthier growth.
