  • April #1
    Look for some of the exciting new cultivars of Hydrangea arborescens, such as Incrediball and Invincibelle Spirit. Invincibelle Spirit is a new pink form that takes a few years to become well-established in the garden, but it will become a showstopper.
  • April #2
    Prune spring-flowering shrubs (azaleas, flowering quince, Forsythia and Loropetalum) soon after they finish flowering, but only if they need it. Selectively cut old or unruly branches by reaching deeply into the shrub leaving no visible stub. making the cut just above a joint. This pruning method will keep them from looking like meatballs.
  • April #3
    A good option for Loropetalums that have outgrown their space is to tree-form them. They can easily be limbed up by removing lower branches.
  • April #4
    Kerria japonica, also known as Japanese kerria or yellow rose of Texas, often has dead branches. Follow them to the base to cut them. Remove older branches the same way to keep the plant looking good. Older, overgrown or neglected plants can be cut to the ground for rejuvenation.
  • April #5
    Azaleas often show symptoms of lace bug and spider mite infestations during the hot months of summer. This damage can be prevented by a onetime early application of the systemic insecticide imidacloprid. This insecticide should be poured in liquid form around the root system as the flowers fade, spreading the active ingredients throughout the plant issue where it remains effective through the growing season. Bayer Advanced Tree and Shrub Insect Control is a common brand that contains this safe and effective insecticide. Always follow label directions when applying any pesticide.
  • April #6
    You can direct seed easy-to-grow flowering annuals and vegetables. Some easy flowers to grow from seed include marigold, zinnia, sunflowers and cosmos. Beans, peas, corn and okra are some easy direct-sow vegetables, while dill, basil and cilantro are some easy direct-sow herbs.
  • April #7
    Try the annual moon vine, Ipomoea alba, this year to attract sphinx moths to your garden. Nick the hard seed coat carefully with nail clippers and soak in water overnight to hasten germination.
