The Q&A Archives: Reuse Trays To Start Seeds

Question: I have some old trays that I used to start seeds last year. Can I use them again and if so what would be the best way to disinfect them?

Answer: Cathy,

Yes you can reuse them. First clean off old dried media or soil from the trays with water and a brush. Then dip the clean trays in a 10% bleach water (1part bleach to 9 parts water) solution for about a minute. Allow them to dry and they'll be disinfected and ready for use.

Thanks for the question. Please stop in again soon!
