hey Jack - is this to replace what is in the containers or just to add to it? Need to get that "top soil" out of there as much as possible.

First question - is this for spring planting or for planting in now? If for spring why not wait and do it then so as to best benefit the spring plantings?

I wouldn't add the gypsum to potting mix. Don't know of any real benefit from it in containers. Works great on heavy clay soil in the garden but others may know of some benefits. I also wouldn't add the blood meal now as it breaks down readily and would mostly leach out by spring planting. I don't see any problems with the rest of your list since you already have the stuff anyway.

Was the MG the potting mix kind or the so-called Garden Soil? Do you compost? Got any of it you can add?

Dave (Digdirt),

The gypsum is to add calcium, not to improve texture.

Dawg,

I think your mix will be fine for cole crops as long as your growing season cooperates.

I can't even think about starting anything here in zone 5 as the first killing frost has already struck way early and the regular killing frost is just a couple weeks away.

Plenty that will survive the frost and nothing that will grow well in the cold temps without supplemental heat.

I am stuck hoping that my brussel sprouts started in August will mature before the cold stops their growth. My extra slow carrots started in spring are now mostly edible size and I will probably just leave them and harvest as needed.

What a year.

Thanks Dave and Guy,

This is an "add to" what I already have. I am planting NOW in hopes to get it at least to the baby stage.
The gypsum is like Guy says.

It was the MG potting mix and another brand.

There is not a lot of "Dirt" in it and I will, of course not be adding more.

THanks again
