Gardener's Calendar

MARCH

  • Finish dormant pruning of ornamental trees.
  • Remove black-knot swellings on plum, chokecherry, and cherry trees.

APRIL

  • Remove Tree wrap from trees.
  • As weather allows, remove winter mulch from roses, perennials and bulbs.
  • Divide and replant overgrown perennials.
  • Prune hedges and summer flowering shrubs, i.e., Annabella Hydrangea, Currant and Potentilla. Check for winter snow damage and prune out broken branches.
  • Till flower and vegetable garden soil and add composted cow manure, peat moss or composted leaves.
  • Fertilize spring bulbs when foliage emerges.
  • Plant frost-tolerant pansies and Johnny-jump-ups for early spring color.
  • Apply fresh mulch around trees and shrubs for weed control.
  • Fertilize trees and shrubs with osmocote. We recommend slow release fertilizer.
  • Wait until the ground is frost free before removing mulch. If temperatures rise early in the season remove part of the mulch, but leave 2-3 inches.
  • Till or spade the soil deeply; if desired add a slow-release flower garden fertilizer.
  • Cut back ornamental grasses.
  • Remove rose cones.

MAY

  • Plant trees and shrubs as soon as the ground is dry enough for digging; late frost and snow will not hurt newly planted trees.
  • Apply crabgrass preventer to established lawns when night time temperature is 50 degrees 3 nights in a row.
  • Work fertilizer into vegetable and flower gardens before they are planted.
  • Mulch flower gardens to conserve moisture and reduce weed growth. Landsburg’s carries 10 different choices.
  • Install peony hoops. They can also be used on Annabelle Hydrangea.
  • Fertilize roses and begin weekly maintenance against blackspot and mildew.
  • Seed new lawns while nights are still cool and spring rains are on their way.
  • Protect gardens from deer browsing.
  • Control dandelions and creeping charlie by applying herbicide before seed heads are formed.
  • Plant tender bedding plants, geraniums, vegetables and bulbs after danger of frost is over.
  • Plant summer-blooming bulbs such as Dinnerplate Dahlias, Calla Lilies, Cannas and Gladiolas.
  • Apply pre-emergent weed control in shrub and planting beds. We recommend Treflan.
  • Remove accumulated leaves and debris from underneath evergreens and shrubs.
  • Prune forsythia, azaleas, and lilacs after they have flowered; all spring-flowering shrubs should be pruned right after flowering.
  • Begin apple-tree spray programs after blossoms drop. Stop in to Landsburg’s garden center for a free spray schedule.
  • Make sure freshly planted trees and shrubs are watered weekly, especially during dry periods. Continue to water through the season.
  • Prune mugho pines when new growth is fully grown and soft.
  • Fertilize established trees, evergreens, and shrubs. Start a fertilizer program.
  • Rake, overseed, and fertilize the lawn. Avoid applying crabgrass preventer to newly seeded areas. Seed new lawns while nights are still cool and the weather is wet.

JUNE

  • Stake larger varieties of perennials such as delphiniums and lilies.
  • Begin leaf-spot control on tomato plants and stake young tomato plants; late-staking contributes to blossom end rot.
  • Tie climbing roses to trellises.
  • Perform last pinching of chrysanthemums to promote compact, bushy plants.
  • Do last picking of rhubarb at month’s end to allow roots to store energy for next season.
  • Mulch your garden after the soil has warmed up later in the month.
  • Fertilize lawns, flowers, and gardens, and continue weeding. Re-apply Treflan to perennial beds.
  • Prune and shape new growth on arborvitae, junipers, and yews.
  • Trim evergreens including junipers.
  • Prune pines, spruce, and fir trees mid month to 4th of July.
