Helpful Information

Determine plant quantity by knowing recommended spacing. We offer three ranges; adjust if mixing ranges. Seed packets, labels, and nurseries also provide spacing. Space for growth but avoid large gaps for weeds. Grouped plants share spacing needs, but varieties of the same species may differ. Find plants for your hardiness zone.

Before planting, till 6 inches deep, add fertilizer/organic matter if needed.
