Would you put your used potting soil in your raised beds? pros and cons?
If you have heavy clay or mostly sand, it will help. If you already have a loamy soil with good organic matter content, it will be mildly detrimental. The peat moss in most potting soils crusts up when it's dry, repels water and inhibits germination. It's also a magnet for cats to crap in if you have that issue. I would mix it thoroughly with the native soil.
Sure. Have done it all the time over the years. Several pros and no cons I can think of off hand. It is an issue that often comes up for discussion on various forums here and I can't recall anyone having any real problems with it.
I am basically trying to just get rid of it. Don't really have room for it in the garbage. I do a large number of very large pots. So, when I repot them , I have all this used potting soil. I do mix about 1/3 back into the new stuff.
Thanks for the responses!
Re getting rid of it; I know many say you shouldn't reuse it but I always just use it over again, for years, in outdoor containers both for starting seeds and for perminant containers. I just add fertilizer and perhaps a little new stuff.
I typically throw it in my compost pile.
I have huge pots and lots of them. Before replanting in the spring, I remove about half of the old potting mix and replace with new. Once all the old potting mix is in my wheelbarrow, I start 'broadcasting' it out over the yard and beds by hand. You would be surprised how much potting mix simply disappears when disposed of this way !
