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.

You can use this in climbing poles for vining plants.

I agree. I've tried to use it as much ground cover. It's one advantage is that it's less bulky to transport over bags however you have to pay back all that convenience in time trying to make it expand on site. Not worth it at all in hindsight.

It's $4/cu ft. Cheap mulch is commonly available for $1/cu ft (the ever-so-prevalent $2/bag mulch deals at big boxes you'll see on SD).

Regular mulch is sourced locally but this is imported. They had to make up for freight cost

Personally, a little pricey for me for larger volume mulch beds, but wondering how this works for pets that use coconut husks at bedding.

I second this. I have a banana ball python and am wondering if this works as bedding

Is this safe for vegetables? Don't use the dyed mulch as I'm worried it'll leach into the veggies

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.

This plus a bag of oats from your farm store and you can grow mushrooms for years.

Excellent deal if you know what you are getting and how to prepare it for specific usages. If you are inexperienced and unwilling to look up information do not buy this. I absolutely love coco my favorite substrate by far.

I've been using reptile substrate in my potting mixes the last couple of years and it's been working well but I'll give this a shot for the price.

I find it so light and when it's windy blows away. How do I do better?

we have a desert tortoise and unfortunately cedar based mulch is not recommended so i had to purchase coconut coir for strawberry plants. it was the only solution i found priced reasonably for pets where standard or unknown mulch is not safe

I wouldnt ever use it as a top cover. Going to have to keep it wet constantly. Best used as a "soilless" hydroponics medium or mixed in an actual potting soil.
