Anyone using glass mulch ? aquaculture filter ?

The local recycling centers are giving it away.

Looks like it would work great mixed in with wood in wood pits, for water storage.

Also looks like a good filter for aqua, could sift out well, and easy to flush for microbial cleaning.

when seeing borken beer bottles in the hills when out shooting, ive though about how glass might affect the soil as a mulch, i would obviously retain moisture in the soil, in fact it does where ive seen glass and pulled a piece up, but it wouldnt really protect the soil from sun exposure, and it may even make it worse and kill more soil surface microbials and mychorizzials, that beign said i havent seen the exact mulch youre talking about but to me personally it seems as if it wouldnt quite help as much as other things, now mixed with woodchips i dont knwo what it'd do, though i do wonder how long it might take to break from shard to dust in the soil and am curious if it would eventually get grown into a potato or carrot or something... which would hurt really bad to bite into lol

It is almost tumbled, so edges are broken down.

In the ancient ag thread , the natives here always plant in sand.
Seems it works as a canteen. The aerial photos plainly show they avoided the dirt overburden, and planted in drift and washes.
So, seems like a good thing to mix into buried wood to keep water pockets and air spaces.

Don't think i would use it on surface, standard rocks would work better as they can grow lichen, and break down.

But the glass buried would work fab, and would prob be good as a wick pocket/channel to suck moisture down deep to root area.

I'm thinking there are alot of better unused free resources to have in your soil. But it's your call, maybe Paul or one of the gurus can weigh in on this.

If the glass is tumbled, it makes a beautiful mulch for a small accent area of for a focal point. It is very expensive to buy bagged tumbled glass so if someone is giving it away, I would take it!
When installing it, use a landscape fabric so that the glass does not become buried in the soil after watering.

I used colored, tumbled glass in a school "literacy garden" that I designed as well as for some clients (I'm a landscape designer) and for some TV garden makeovers I've done.

Glass also works well in a fire pit and in outdoor fireplaces.
