I love used potting mix - it seems to take longer for water to wick up and soak it (I always try to bottom water) but wow - does it do great.

In the Greenhouse, I have several tomato plants growing and I'm using a combo of garden dirt, used potting mix and compost, along with maybe a tablespoon of Vegetable-tone fertilizer (I couldn't find any Tomato-tone handy) in a seven gallon pot. I also try to add about a cup of compost tea every other week.

When you dump the old pots out, take a good deep sniff of the soil that was on the bottom of the pot. If it smells rotten then throw it out but if it has an earthy smell then it's fine to use again. Old hair like roots will just add the the N.

Thanks, all, for the input! I felt a whole lot better after hearing that I hadn't set things up for a horrible, diseased mess.

Just saw my first lettuce and spinach sprouts last night! Thanks again,

It would be best to pasturize used potting mix.
