Fertilizing


  • fertilize your shrubs if you didn’t in the fall

Planting


  • The average last spring frost date in Alexander County is April 6, +/- 11 days.
  • Summer bulbs
  • Warm season veggies! (Green beans, Cucumber, Squash, Pumpkins, Tomatoes, Peppers, Melons, Eggplant, Corn)
  • Replace your cool season annual flowers with summer annuals
  • Perennial flower seeds (Hollyhock, Coreopsis, Daisy, Phlox, Sweet William)
  • Small fruits (like those from our fruit sale that you haven’t got in the ground yet…) (Strawberry, Blueberry, Blackberry)

Pruning


lady pruning bushes
  • Prune spring flowering shrubs after their flowers fade
  • WAIT for herbaceous spring flowering perennials turn brown on their own before cutting them back (they need their leaves to make energy to store for next year)
  • Prune berry producing shrubs like holly and pyracantha while in flower to prevent complete removal of all of this season’s berries
  • Trim out any winter/cold damage that’s occurred this season
  • Cut back butterfly bushes (if you haven’t already) to approx. 3ft or as desired
  • Trim back ornamental grasses (if you haven’t already)

Lawn Care


  • Maintain mowing height of fescue and bluegrass at 3 inches.
  • Do NOT fertilize cool season lawns such as tall fescue or Kentucky bluegrass anymore this spring.

Spraying


  • Insect oil on fruit trees
  • Check azaleas, rhododendron, and pyracantha for lace bugs and treat if needed
  • Spray roses before buds open
  • Control poison ivy, honeysuckle, and kudzu while new growth is young

Propagation


  • Good time to layer plants by lowering a branch of your favorite shrubs and covering it with soil and a stone

simple layering and mound layering

Specific Chores


  • Visit local garden centers and nurseries!
  • Mulch landscape beds (if you haven’t already)
  • Make sure water features and gardens are clean and unclogged (we don’t want any ‘skitters!)
