April Gardening Checklist

April Gardening Checklist

Vegetables

  • Enjoy herbs in pots in a windowsill. Plant them outside in May.
  • Remove any spent vines and corn stalks from garden spot if not completed last fall.
  • Add Soil Enhancer or compost as well as sulfur, and rototil into soil to prepare seed bed.
  • Cool weather crops (lettuce, spinach, peas, broccoli, root crops) can be planted in late April.
  • Tomatoes may be planted in late April in a hoop house or in insulated plant protectors.
  • Place a floating row cover over your crops so your seeds will germinate quicker, and the birds won’t make a meal of them. Floating row covers also eliminate cabbage worms and root maggots on cabbage and root crops.

Fruit

  • Prune and thin raspberry plants to clean up last year’s dead canes.
  • Apply manure and soil sulfur to berry patches if not done last fall.
  • Apply Casoron granules to raspberries before new canes emerge to prevent weeds.
  • Plant bare root or potted raspberries, strawberries, and fruit trees.
  • Spray mature fruit trees with Dormant Spray to kill overwintering insects and eggs.
  • Spray pear and apple trees with Fertilome Fire Blight Spray twice during blossom period.

Lawns

  • Rake matted grass as snow recedes to prevent snow mold from damaging your lawn.
  • Turn on sprinkler system and make repairs as needed.
  • Apply T&C Humates (Step-1) to your lawn to help decompose lawn thatch and green up your lawn. This can be done anytime in March or April.
  • Ask about our 4-Step Lawn Program for the greenest, healthiest lawn in the neighborhood.
  • Seed new lawns using our Premium Lawn Seed. Apply T&C Seed & Sod Starter at time of planting. Ask for our free Lawn Planting Guide for complete details.
  • Spray dandelions with Fertilome Weed Free Zone before they bloom.

Roses

  • Remove winter protection from roses when new shoots are just beginning to emerge.
  • Prune canes to 8” on hybrid teas. Remove dead canes.
  • Plant dormant roses. They love getting started in the cooler weather.
  • Apply Fertilome Rose Food w/Systemic to feed and protect roses from insect damage.

Flowers

  • Plant Sweet Pea seed and wildflower seed now.
  • Plant perennial flowers (the ones that come back each year). Frost won’t bother them.
  • Hardy annuals such as pansies, petunias, alyssum, snapdragons can be planted in late April.
  • Plant summer bulbs like gladiolas, lilies, and dahlias for beautiful summer color.
  • Plant up your porch pots with cold hardy flowers. Ask for our tip sheet on hardy annuals.
  • Prune back dead stalks on perennial flowers and ornamental grasses to the ground.
  • Transplant, divide, and relocate perennials as needed. Share some with a neighbor.
  • Fertilize established bulbs and perennials with T&C Fruit & Flower Food.

Trees & Shrubs

  • Plant potted and bare root trees and shrubs. Use Root Stimulator and Soil Enhancer.
  • Prune most trees now. Skip maples and birches until summer to avoid excessive bleeding.
  • Cut back butterfly bushes, blue mist spirea, Russian sage, potentilla, spirea, and other summer-blooming shrubs now.
  • Fertilize trees and shrubs with Save-A-Tree or T&C Tree & Shrub Food.
  • Apply Fertilome Systemic Insect Drench or Acecap Systemic Implants to prevent insect damage to your trees and shrubs for the entire growing season.
  • Spray dormant trees with Dormant Spray to kill overwintering insects and eggs.
  • Spray quaking aspen with Fertilome Systemic Fungicide to prevent fungal leaf spot.
  • Examine staked trees and loosen or remove ties around trees if necessary to prevent injury.
  • Check for evidence of borers in your aspen, ash, and other trees. Small holes, possibly with leaking sap and/or sawdust are signs of problems. See our Garden Advisor for solutions.

Birds and Wildlife

  • Clean and fill your bird baths for arriving robins and songbirds.
  • Clean your bird houses before the new birds arrive.
  • Continue to feed birds with suet, black oil sunflower, and high quality wild bird seed.
  • Plant shrubs and flowers to attract, feed, and provide cover for birds and hummingbirds.

Always read and follow label directions when using any garden chemical or fertilizer.
