3. Gather Your Soil Enhancers
Typically, the most important additive for your soil is decomposing animal or plant matter, such as compost, peat moss and well-rotted manure. You can make your own compost year-round with a hot compost bin or worm compost farm. Be warned that neither method may produce enough compost over the winter to enrich a large garden. Because I clean and freeze so many fresh vegetables in the late summer and fall, I don't end up with many vegetable scraps to feed my worms in the winter. Not to worry: plenty of good organic compost and other organic enhancements are available for purchase.
Also pick up organic fertilizers based on the recommendations in your soil test. For highly acidic soil, add lime. To balance out alkaline soils, add small amounts of pelleted sulfur.
