Transplant seedlings outdoors after all danger of frost has passed
Space plants 18 to 36 inches apart depending on variety
Plant seedlings deeply, burying part of the stem to encourage strong roots

Apply mulch around plants to retain moisture and suppress weeds
Provide support with stakes, cages, or trellises
