How to sanitize pots between growing seasons?
Scrub empty pots with a brush to remove old soil. Soak in a 10% bleach solution (1 part bleach, 9 parts water) for 30 minutes. Rinse thoroughly and dry in full sun for 2 days. Alternatively, soak in a neem cake solution for 24 hours. Refill with fresh potting mix before replanting to eliminate Fusarium and nematodes.
