Pinpoint chalky soil by its larger, rocky pieces and its tendency to drain well, like sand. Like some places in East Tennessee, you find this soil type over limestone bedrock and chalk deposits. These minerals cause the soil to be alkaline, and you can lower the pH by adding composted materials and sulfur, for example.
Pros: Chalky soil drains water freely. Cons: It’s alkaline and can stunt growth or yellow leaves. Balance pH and workability with organic humus. Vegetables: Lilac, Weigela, Madonna lily, Pinks, Mock Orange Ornamental: Spinach, Beets, Sweet Corn, Cabbage
