Don't do this. It's a natural sponge. This will rot the roots. Adding perlite helps but these are large chunks. The roots will grow into the chunks and within each chunk there will be no perlite or air. Just wet sponge. The roots will hate it. I speak from experience after trying this.

It is a good mulch but not a good soil. Use the nonchunk version of Coco coir for soil.
In store price is $14.99
Used this a few years ago. Lasts about the same as regular bags of mulch and more of an effort to use, as well as more expensive. I would not really recommend, and will not be using again.

My method is free and is a lot easier.
I save the leaves from the previous fall, and store them in refuse bags.
Come spring time I spread them on top of my garden bed.
This will be my second year doing this, and it seems to work perfectly fine.
Shred them with a lawnmower before you spread them, that'll keep them from matting up and causing water issues. Shredded leaves are great mulch though, I'm doing the same thing for my veggie plants this year.

Why does this have so many TUs? Seems it is only a good deal for niche situations, but way too expensive for typical mulch applications, especially when even bagged wood chips can be had for much cheaper?

Wow...thanks for commenting this. Is it okay to use on top of soil? Like around a small tree? That's what I did and now I'm afraid it will die.

By refuse do you mean large black plastic bags? I want to try this but don't want to mess up

As long as you don't bury things into the roots, it won't cause root rot. When people say they bury fish, apples and stuff into the soil, stuff like this has potential to cause root rot IF the roots contact the stuff before it has time to break down. If you want to put chunks of this stuff into the soil, make sure to mix with dirt in the hope that water will be absorbed and dried in between rain and watering.

Ah okay cool. It seems spreading some of this stuff on top of soil is helping not dry out so quickly

Yeah, it's a good mulch, it does take some time to break down since it says it is chunky.

I once kept leaves in a plastic trash can a bit too long. they started to warm up and compost and smell a bit, but I spread them out anyway - big mistake. I think they let off spores that tended to land on painted wood and leave black spots. I think leaves on the ground as cover is fine, but I won't ever keep them enclosed for any duration anymore.

I got this at Costco a couple of years ago. It's a waste of money. In fact such a bad product I had them refund my money. It doesn't expand, it is difficult to break apart even following their directions, just buy regular bagged mulch.

Haven't been to Costco this spring. Anyone know if they have the big bags of potting soil in stock?
Edit: looks like it's available online via instacart so probably in stock in the stores. But thereviews [costco.com]? Yikes!

Been looking for this. Use it every year to mulch my organic garden pots. Other mulches have coloring / chemicals etc that I don't want in my veggies.
For first use you have to soak it, read the instructions. I also mix it into the soil the next year. If it gets too dry it can blow off.

Is this the same stuff they use in composting toilets?

That's artillery fungus. I had it at my last house probably from a load of mulch. Those black spots are REALLY stuck on, too. Even a pressure washer wouldn't scrape them off.

I meant those large, brown paper bags they sell at places like home depot and lowes. No plastic.
