Yes, that stuff is very heavy ...a friend who has a garden center asks his customers what soil they used when they complain about a plant that died, and it is almost always M.G. He uses Promix blended with soil conditioner.

Hi
Always a lot of controversy about potting soils . Since I grow most of my potted plants outdoors I suppose it makes a lot of difference. Works great for me though I usually add pine bark fines or coconut chips for the palms.
In the shadehouse I grow mostly epiphytes so no potting soil. Terrestrials are grown in the ground.
Interesting about "Cannas" I grow most of them in standing water in a pond.
I would imagine your much cooler temps make a lot of difference. gary

Moisture Control soil? Does that have water-retaining granules in it? For my hanging plants, I add a few granules to my potting mix and it works pretty good.

Thanks for the warning on not using it for starts or overwintering.

I normally use Black Gold which is a local product but I wanted to try the MG MC for fuchsias in hanging planters since they dry out easily in our brief summers. I lost two out of three fuchsias that I put in the greenhouse for winter.....rotted right off and so did my Gardenia radicans and Canna 'Stuttgart' and multiple others.....

I don't know if it has moisture gel in it or cocoa fibre or both.

Hi
Wouldn't it be wonderful if a list of ingredients was required right on the package?? Then you'd be able to make informed choices . Oh wait then you might buy another product.or worse make your own .lol

I HATE the fact that they add stuff to all their mixes. They have so many different mixes now it's ridiculous. I don't even bother buying anything but their potting soil and I even add a generous amount of perlite (NOT theirs!) to it. They even add fertilizer to their PERLITE which is ridiculous too.

They saturate the market with a LOT of stuff you just do not need IMHO.

Hi
Wild guess but I'll bet they're making what sells. The local box stores here carry almost nothing else. according to a clerk it sells 10 to one over other brands.
Only thing you can do is experiment with what works for you. Some interesting formula on the "Container " forum. Generally I use 5 parts pine bark fines 2 canadian peat 1 perlite throw in some builders sand for succulents. Again all mu pots are outdoors not in a GH gary

Most people don't have greenhouses so it is probably fine for them.

The moisture control is great for the summer outdoors but really is too heavy for a greenhouse. I've used the standard MG potting mix and it works fine in the greenhouse, Promix also. But MGMC is reserved for the outdoors.
