April Lawn & Garden Checklist

Hello, spring! April is the month that makes it all count for a beautiful garden. Start preparing your lawn and garden for a beautiful growing season.


  • Thatch and/or aerate your lawn (this must be done before applying your preemergent weed control).
  • Apply Fertilome For All Seasons preemergent weed control with fertilizer for crabgrass control and other weeds. The ground should be warming when you apply the preemergent. It may be mid to late April before you get it on your lawn.
  • Plant grass seed (do not use For All Seasons when seeding, use Fertilome New Lawn Starter in those areas).
  • If you have brown spots from your pets apply Lime or Gypsum to neutralize the soil and replant the grass seed.


  • Till your garden and apply either Milorganite, Hi-Yield Garden Fertilizer, or Espoma Garden Food as a broadcast.
  • Plant your seed potatoes and onions from early April to mid-April. Apply Hi-Yield Super Phosphate to crops that are harvested for their roots or are produced underground (also carrots, beets, parsnips etc).
  • Mid-April plant earlier season vegetables such as radishes, carrots and beets.
  • Late April and early May plant cabbage and other cole crops.

Trees and Shrubs

  • Start your fungicide applications when buds start breaking. Use Fertilome Broad Spectrum fungicide for leaf disease prevention such as anthracnose and leaf spot. On fruit trees use Fertilome Fruit Tree spray for blight or Immunox to control Cedar Apple Rust and many other diseases. See our staff on frequency of applications.
  • Fertilize with Fertilome Tree Food in mid to late April.
  • Use Hi-Yield Iron with Soil Acidifier or Iron + for any trees showing iron deficiency last year.
  • In mid-April start planting bareroot trees from Parkview Nursery.


  • Cut down any perennials not cut down last fall, including grasses.
  • Fertilize with Fertilome Garden Cote, Osmocote or Fertilome Rose and Flower Food for slow-release fertilization.
  • In late April check out our selection of new varieties and oldies but goodies to add to your current gardens or start a new one!
  • Apply Hi-Yield Herbicide Granules to all of your flower beds for protection against weeds germinating.


  • Start raking back leaves and mulch that were protecting your roses through the winter.
  • Cut back to the point where new growth has started (you will see where the winter climate had killed the branches and turned them purple/brown and the new growth has a green tint to them).
  • Apply Fertilome Rose and Flower Food every 6-8 weeks.
