Too often, transplanting seedlings into the garden seriously sets them back. These biodegradable pots help smooth the transition. They're made from wood fiber that's amply sturdy for starting seeds, yet rapidly biodegrades once placed in soil. So you can place plant and pot into the garden without disrupting the plant or damaging tender roots. The pots are made in France from sustainably grown wood without glue or binders, so they're suitable for organic gardening (OMRI-listed). Also eliminates the need to discard plastic pots. Set of eighteen 3-1/2" square pots.
