10 Garden Questions You're Afraid to Ask
Can I plant as soon as the weather warms up?
You can plant cool-season annuals and vegetables such as peas and lettuce when there's still a threat of frost, says Chip Tynan of the Missouri Botanical Garden. But hold off on warm-season annuals and vegetables, such as tomatoes (left), until your area's frost-free date. (Get the date from a local extension office.)
You can plant most potted perennials, trees and shrubs anytime the soil is workable--even late fall. "As long as the ground isn't frozen and we are not in the grip of a desperate drought, you can plant container plants," Chip says.
