Potting Medium

[estación seca]

250 F will kill bacteria, insects, fungi and protozoans, but perhaps not all viruses. Prolonged heating is necessary to ensure heat reaches all the crevices. 500 F is risky; trapped water in crevices will expand to high pressure steam, and some containers will explode in your oven.

Yea, I've heard about the risk of clay exploding in a high heat situation. One more reason I just wouldn't want to mess with all of that. Total PITA, IMO anyway.

10% bleach solution is my choice of cleaning method and with the extra long soak time and then the time out in the sun...well, it's the best I can do and I hope it's enough. I don't clean/reuse pots on plants that tested positive. The few plants that have tested positive for virus...the pots were pitched along with the plants.
