Thoughts on reusing soil?

What do you guys think about re-using your soil? Good idea or no? I was thinking about it, and it seems like it could be done, and i wouldnt spend all that money on soil, the current soil im using is FF Ocean Forest.

I have heaps of used dirt in my garden, I use if for my garden plants every year, works great. If you've had any insect problems I would sift threw and spray with an organic pesticide a couple times. Probably should do that anyways if its sitting outside to cook. Add some organic fertilizers into your mix to amend

I've had great results reusing soil.
I add a small bag of 'fresh' soil to the old (probably just for my own comfort)
and treat with an enzyme(recently switched to growmore's bio cozyme) to break down any root merial that remains.
Adding some organic powder ferts/amendments and glacial rock dust or azomite to replace some micro elements is never a bad idea

My soil mix started life as 50% Ocean Forest, 25% happy frog, 25% perlite. I now compost it and add a little of this and that here and there. Works better than it ever did new.

I think it depends on the amount of soil you need. If it's a smaller grow or you don't have to room or the time to composit I'd just buy new soil. Find a wherehouse type of gardening store. I can get FFOF for about $8 a bag. If I had the time and space I would rather mix my own though.

Do you do that as you re-pot, or do you have a holding bin where this breakdown occurs? (Do you have to let your old soil "compost" before using it?).

The only thing I would add is that you probably won't have the best results by going straight into the same exact soil. Other than that, I say go for it. I'm talking living organic soil by the way. I add compost and other very much living amendments to all my mixes anyway, my compost always has creepy crawlies living in it when I add it, same with my homegrown castings, and no negative infestations....ever so I don't really worry about that, but please don't take my situation as rule on that. I'd say preferably though the way to go is to compost your old soil for 6 mo. to a year then add it back in with freshy.

I like to cook my soil after adding the goodies for a minumum of 4-5 months with the lid closed in one of these. 64 gallon from Wallyworld.

Haha that's nearly exactly how my back yard looks!, but I use them to store scrap wire. I Actually have a 4x8x4ish hovel style compost and that holds about 14 garbage cans haha. The thing is when you up your compost to a decent size it'll be cooking at freezing air temps. We spent nearly a month at below zero F and my compost never froze inside.

There is bark mulch plants around, and they put out spontaneous combustion fires out on the inside of there mulch pile in winter. Microbiology rules.

I prefer one or two 'enzyme treatments' throughout the course of the plants life cycle, then I add the old dirt to a compost bin (spare trash barrels work nice) with an enzyme treatment and some mycos. Yes you should then let it compost, or 'cook' in the holding barrel for at least 4 weeks. Some guys like to go months (especially when they add a slew of amendments and grass clippings and leaf matter to their compost)

The enzymes will catalyze food production for your micro life, and your microlife will go into overdrive. Similar to the way mycos catalyze food production for your plants.

That is all good if you do organic! I do the same as GWN does.

If you use synthetic nutrition,,,,,,I wouldn't even try it.

Dr. Who is absolutely right.

I use Roots Organic and Nectar for the Gods nutrients, but I do have 3 or 4 synthetics that I run (soul synthetics peak, infinity, swell, and amino aid).

Those 4 particular synthetics don't give me any problems in my recycled compost, BUT they are derived from almost entirely natural sources. Plus I only use small amounts in moderation.

If you're feeding your plants an abundance of chemical ferts, then be careful trying to reuse it.. or if you're using a soil thats got synthetic time release fertilizers, DON'T re-use it.

Great point, I think I may have write it up there somewhere, but everything I said pertained to living organics
