Planting:


  • Plant a tree for Arbor Day! (March 18th)
  • Plant small fruit plants, grape vines and fruit trees before the buds break
  • Transplant or plant new trees, shrubs, and ground covers so their roots can get established before summer comes!
  • Plant seeds of the following perennials: columbine, hollyhock, coreopsis, daisy, phlox, and dianthus (Sweet William)
  • Plants of broccoli, cabbage and cauliflower should be set out in the garden in mid-March
  • Plant seeds of these vegetables: beets, carrots, Chinese cabbage, kale, kohlrabi, lettuce, Swiss chard, turnips, potatoes, cabbage, broccoli, and cauliflower.
  • Start any annual flowers or warm-season vegetables inside your home that are not commercially available in early March

Pruning:


  • Finish pruning fruit trees, blueberries, grapes, blackberries
  • Prune spring flowering plants like winter honeysuckle, flowering quince, and camellias after their flowers fade
  • Prune roses late in March
  • Shrubs like abelia, mahonia and nandina can be pruned this month if needed
  • Dead-head or pick off faded flowers of pansy and daffodil (they will flower longer if old flowers are removed)
  • Overgrown shrubs can be severely pruned (not needled evergreens)
  • Trim ornamental grasses like liriope, Mondo grass, and pampas grass (a weed eater will work perfect!)

Spraying:


  • Spray peach and nectarine trees with a fungicide to prevent leaf curl
  • Spray all fruit trees with dormant oil to help eliminate some insects (after pruning)

Lawn Care:


  • Fertilize with cool-season turf with 10-10-10, but NOT with slow-release fertilizer
  • Apply crabgrass preventer to your lawn to help control crabgrass in the turf
  • Mow tall fescue lawns as needed
  • Seed fescue and bluegrass if not done in September

Propagation:


  • Continue to divide perennials like daylily, shasta daisy, gaillardia and coreopsis

Specific Chores:


  • Restock on garden supplies like fertilizer, insecticides and fungicides if needed
  • Make sure all garden equipment, lawn mowers, tillers, hedge trimmers, tools, hoses and sprayers are ready to go for the season
  • Be certain that old plantings of perennials like peony, hollyhock and phlox are clean of last season’s growth
