Such a great product

I've always loved Black Cow. I haven't needed it in years, but it's still just as great years later. This year, I needed it to mix with my soil and sand for growing blueberry bushes in grow bags. Beware, it can contain pretty meaty rocks or small bits of plastic. I've been able to pick stuff out when I see it, maybe 2-3 pieces per bag. Despite that, I still highly recommend.

Good for the cost

Compared to other types of composted manure I have used, this was pretty decent. Some brands are full of wood chips and sand, while this was mostly dark, composted material containing only small bits of wood. Keep in mind this is not all manure, but composted with "soil". As such it has very low NPK nutrient content. If you want higher nutrients you will have to pay more for actual manure, not composted manure. I thought this good for the price.

Pleasantly surprising for store bought compost

I was actually pleasantly surprised by this big box store manure compost. I purchased along with a different brand bag of manure compost and it's definitely superior in color, smell, texture, and moisture. The Black Kow is very dark, nearly black, and has no foul odor just a nice earthy smell like healthy compost. Very moist and very few if any larger chunks or sticks. I make my own compost but ran out and needed help filling some new pots in my vegetable garden, this is definitely the brand I'll plan to use in the future if needed.
