Container Toms: Reusing this year's mix?
I'm growing quite a few toms in containers this year for the first time and have put a fair amount of money into the potting mix I use. I'm wondering if up here in Minnesota I could get away with reusing at least some of the mix next year. My thought was to devote one of three sections of my huge composting area to the mix, putting down a layer of landscape cloth at the base. Is it utopian to think our severe cold would help render the mix more acceptable for use next spring? The alternative is to dump it into the compost heap or on the gardens at the end of this season and just start over for the containers next year. But it would be nice to save some money as well. Any advice or experience appreciated. TIA, Gary.
