Why add compost to the soil?
Compost enriches the soil by adding nutrients and retaining nutrients in the soil and feeds the soil biology. Compost improves water holding capacity, essential for sandy soils. Compost helps loosen heavy soils thus increasing space for oxygen and water also allows roots to spread easier.
You can make your own compost with the use of compost bins or compost piles, or purchase bagged finished compost, ready for the garden. We have a great video on Hot and Fast Composting.
