Take a look at what to do these upcoming months
Gardener's Calendar
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.
JULY
- Remove spring bulb foliage as it browns.
- If spring-flowering bulbs aren’t doing well, dig up bulbs after the foliage has died and divide.
- Water, weed, fertilize, and harvest vegetables.
- Before late summer, transplant and divide perennials.
- Continue to water young trees and shrubs weekly.
- Complete evergreen pruning before the end of the month to prevent winter injury.
