RAISED BED GARDENING - How to Grow a Raised Bed Vegetable Garden!

The main components of the Mace garden mix are compost, coconut coir (or coconut pith), worm castings, and rock dust minerals including trace elements.

Coconut coir is used instead of peat moss because it is more sustainable and renewable. Although it does not contain much nutrition, it helps retain moisture in the soil.

Worm castings are essentially worm poop that looks like black coffee grounds. They are considered "gardeners' gold" due to their high nutrition content for plants and are an important component for a healthy garden.

Adding rock dust minerals to the garden mix helps remineralize the soil, providing essential minerals and trace elements that are often lacking in the food due to depleted soils. It supports healthier plant growth and nutrition-rich produce.

The garden mix should be replenished after each growing season by adding more worm castings, compost, and rock dust minerals.

Adding a thin layer of coconut coir on top of the soil provides a spongy, moist environment that aids in seed germination, allowing the seeds to sprout easily and their roots to grow down into the nutrient-rich mix below.
