What is Black Kow?

Black Kow is a brand of potting soil and organic soil amendments based out of Oxford, Florida.

The brand is run by a small team that is dedicated to producing quality growth mediums for the home gardener. They have also donated their products to many community gardens in their area to promote the love of gardening and growing your own food.

Black Kow sells four main products:

1.   Black Kow Mature Manure

The Mature Manure is one of the most popular products from Black Kow.

It is made from 100% organic cow manure that has been composted to prevent the unpleasant smell associated with regular manure.

This product has ten times more nutrients than most garden soil, so it is an excellent food source for your plants. The slow-release system means that the roots can comfortably absorb the nutrients without the roots burning.

In sandy soil, the Mature Manure will improve moisture retention, while in clay soil, it will improve aeration and regulate moisture levels. It really is a product that will be beneficial to all soil types.

2.   Mushroom Compost

This is a specialized compost created using the soil from growing mushrooms.

The soil is used to grow mushrooms just once. Then, once the mushrooms have been harvested, their soil is composted, bagged, and sold to home gardeners as a nutrient-rich soil amendment. It is best used when mixed with your soil or as a top dressing for potted plants.

3.   Black Kow Topsoil

This topsoil is an organic material made from the Florida peat deposit.

It works perfectly as a top dressing for lawns or as a fill for any bare spots. It can also be mixed with the Mushroom Compost or Mature Manure to create a rich planting medium with a great texture that can be used in container gardens, pot plants, or raised beds.

4.   Black Velvet Planting Soil

The Black Velvet Planting Soil is Black Kow’s all-purpose soil option that pairs very well with their soil amendment products.

The soil is loose in texture for easy root penetration and provides a long-lasting food source for your container plants. It works very well when combined with the Mature Manure or Mushroom Compost.

The Black Velvet Planting Soil is suitable for pot plants and raised beds.

We prefer to use a combination of manure and potting soil (Black Kow’s Mature Manure and Balck Velvet Planting Soil) to create the perfect blend to grow your plants in.
