Sterilize Containers for Planting Seeds

Head Start
When reusing containers be sure to properly sterilize them first.

Whether you recycle nursery containers or reuse those from last year’s garden, make sure all are properly sterilized before planting seeds. Containers for planting seeds must always be clean as can be before planting!

Wash out all remnants of soil or organic matter sticking to the sides. Then dip each clean container into a bucket containing a 10% bleach solution to kill any remnants of prior diseases that could attack your seedlings. Wait until your clean, sterilized pots dry before adding OMRI Listed Black Gold Seedling Mix for a safe, sterile germination bed for your seeds. Not only does it do a great job, but this mix is approved for organic gardening!
