Spring Garden Calendar

Zones 3-5: May

•Insects: Treat aphid outbreaks with insecticidal soap or horticultural oil. For smaller infestations, a blast of water removes feeding aphids.

•Plantings: Choose annuals that flower all summer, such as angelonia, zinnia, pentas, and trailing petunia. When frost is no longer a threat, plant canna and calla lily outdoors.

•Edibles: Set out warm-season transplants of tomato, okra, and pepper. Sow cucumber, bean, and melon seeds.
