• Plant seeds that like warm soil. Sow corn, squash, cucumbers and melon seeds or seedlings when the soil has warmed to at least 65° F, usually two weeks after the last frost date.
• Finish planting annuals in containers and in bare spots in your garden. Large greenhouses will still have lots of selection at the beginning of the month.
• Divide and transplant most late-summer and fall-blooming perennials now. Wait to divide spring bloomers until fall.
• Continue planting trees, shrubs and roses. But don't plant bare-root types. They need cool, wet weather to take off.
• In the northern Midwest, continue to plant gladiolus corms, canna rhizomes, begonia tubers, and other summer bulbs.
