The Ultimate Gardening Guide for April:

ANNUALS:

  • Plant cool season flowers into containers, these include: alyssum, nasturtium, pansies, Violas, annual lobelia, geraniums and calendula. If temperatures fall and frost is predicted, bring them indoors for the night.
  • Get on top of any weeds in the garden. Once the warm weather hits they will spread like wildfire.
  • Start warm weather annual seeds indoors, these include: zinnias, melampodium, blue sage and spider flower.
  • Sow the cold weather annual seeds outside directly in the garden.

BULBS:

  • Fertilize bulbs as soon as they are done flowering. Cut back flower stalks. This will allow leaves to grow hence storing energy in the bulb for next year.
  • Water bulbs that have not yet bloomed.
  • Remove accumulated mulch from around and above flowering bulbs.
  • Use natural (our recommendation whenever possible) or chemical deer repellent on emerging tulips, hastas, or lilies.
  • Apply natural (again our preference) or chemical insecticides to control iris borers.

PERENNIALS + ORNAMENTAL GRASSES:

  • Enjoy and deadhead early-blooming perennials, this will tidy up the plants appearance and encourage new growth, as well as a healthy root system.
  • Clear any remaining debris or leaves from garden beds to allow emerging perennials to grow.
  • Transplant perennial seedlings that you started indoors into larger pots so that they can get bigger before moving out into the garden
  • Plant bare-root perennials.

GROUNDCOVERS:

  • Plant new groundcover beds in Zones 7-8. Mulch to suppress weeds.
  • Remove any winter debris from groundcover area.

SHRUBS:

  • Order shrubs and keep them in a cool dry place while it is still too cold to plant them outdoors. If any break dormancy and begin to sprout before the last frost , pot them and keep in the garage or basement. When the time comes to plant them outdoors, soak the roots in water overnight before planting.
  • Be on the lookout for spring pests. If you think you have an infestation, take a sample or photo and take it to your local nursery for diagnosis and treatment options.
  • Trim/prune evergreen hedges.

TREES:

  • Fertilize: April is a good time to fertilize hollies in particular.
  • Check trees for pests. Eastern tent caterpillars, leaf miners, stem cankers, and apple scab symptoms typically show up during April. Again if you notice an issue or are unsure we once again recommend taking a picture or sample to your local nursery for diagnosis and treatment.
  • Plant bare-root and container-grown trees into the ground. Soak the roots in water the night before planting.
  • Stake newly planted trees and check on last years planted trees (if any). For trees staked the previous year, the straps can most likely be removed, if the tree doesn’t show too much movement.

TURFGRASS:

  • Repair any damaged parts of the lawn. Overseed where needed or use cut sod patches if necessary.
  • Overseed thinning area where the lawn is looking barren.
  • Install a new lawn from seed or sod if you have not yet done so in the fall.
  • Fertilize!

VEGETABLES + HERBS:

VINES:

  • Start annual vines from seed indoors. Vines don’t like to be disturbed, so start them in containers that are large enough to allow for enough growth until the time comes to plant them outdoors.
