Winter 2020 Garden Prep
Use sulfur to lower the soil pH. Spread the sulfur over the surface of the garden bed and work it into the top 12 inches of soil. Sulfur requires about three months to alter the pH, so fall application works best. New Castle Gardens carries sulfur in 4# and 50# bags.
Spread compost over the surface of the bed. Apply it in a 2-4″ thick layer. Compost improves soil moisture retention and drainage, while also improving the texture of sandy or clay soil. Mix the compost into the top 6 to 8 inches of soil with the spade or tiller. New Castle Gardens will be using Black Gold OMRI Garden Compost this year.
