Do any of your reuse your dirt from outside? If so how do you sterilize and recondition it? I see alot of people using pro-mix or sunshine mix + amendments. Do you just buy 20 more pallets every year and throw away the old?

I let the rain do it's thing all winter then add some new soil and nutrients. Some holes are 6 years old. Still produce as well as new holes.

I grow like Below Fridgid. Ive used many of the same holes for 20yrs. Each fall i cut my plant, mix in 1 cup of 10-10-10( no substitute for fall fert apps) . another light dose in the spring and the hairy monsters appear.

I have to add a cup of lime and 5 gallons of new dirt every 4th year.

people have told me to take all my dirt and wrap it in a black tarp in the sun for 2 months to germinate the spores and bugs and let them die. anyone else use this method of sterilization?

My old soil from outdoor/indoor pots goes straight into the compost heap, once the heap gets up to working temp it will sterelize itself.

could i start a compost heap now and have it ready for middle of may planting?

Mid May would be a bit too soon to use compost you start making now, 3 months is usually the minimum.

Content Type - most garden and kitchen waste will break down pretty fast (within three months so long as it isn't too cold, the particles are well mixed and of relatively small size). But certain foodstuffs such as bones and egg-shells are pretty dense. These will take 6 months or more to break down. Manure from people (humanure) or animals from non organic farms may contain veterinary chemical residues. These will be gone in three months. But if you farm organically and sell your produce, you may need to adhere to Soil Association guidelines requiring you not to use such composts (including non-organic pig or poultry manure) for up to six months

The heap wont be ready for planting out time but you can still fork it in as a top dressing/mulch in the first inch or two when it is ready.

great advice bosco. what kind of manure do you use?

The stuff that comes out of the arse end of cows and rabbits :)

Fresh for the compost heap and year old for a mulch.
Bunny poo just gets sun dried n powered then spread on top of the soil.

you can get great compost in 30 days!! you have to turn it like mad though. the Earth Soil Factory in Chico makes theirs in 30 days, and I know of other people who get good, high quality compost in 30 days.


YES YOU CAN REUSE SOIL!!! in fact it get's better over time if you take the biological approach and treat it as a living organism... if you add compost tea to your soil then it will be better each year...

yeah, once you got a hole or strip of amended soil,worms gonna come even, it'll even get better and it'll be fine as long as it stays enriched with nutrients, hah

I amend the native soil with used soil from porch/deck pots every 2 years with worm castings mixed in as well. Sprinkle some 10-10-10 in each worked hole and by the time all 25-40 holes are dug, it is time to start planting the seedlings.

I don't like to use manure. So many folks use wormers on their livestock and that can affect the amended soils we use for our in ground plants. If I don't spot many worms while prepping holes, I'll go to Wal-Mart and buy them from vending machines and give them a new home instead of drowning them.

Spent my St Paddy's Day at primary site doing some prep work. Scouting for new site/s this weekend. Some place to start seeds on site in mid May. Have some corn field dirt to amend those holes.

does anyone water their soil with hygrozyme in the early spring to get rid of all the root mass in the old soil? is there any other alternatives?

Bacillus Thurigensis for fungus gnats (which have come in ever batch of FFOF and Roots Organic soil)... The brand Microbe Lift is cheeeep. Made for ponds.

Spinosad, but not on your buds and only on ce a month. Predator namatodes and predator mites for thrip larva in the soil. Start early as these take time to do their thing.
