Things to do this month
  • Plant trees, shrubs, vines, ground covers, perennials, and fruit plants of all types.
  • Plant vegetable plants and seeds, annuals, herbs and tender bulbs.
  • Prune flowering plants and shrubs as they are done flowering. Remove spent blooms or developed seed pods from tulips, daffodils, hyacinths, etc. Do not remove or tie up the green leaves. They are replenishing the bulb for next year's blooms.
  • Fertilize as needed.
  • Use a time-release fertilizer when planting annuals for lots and lots of blooms! (You can do this in addition to liquid "bloom" food feedings for fabulous results.)
  • Watch vegetable garden for developing insect or disease problems.
  • Mow grass to a height of 2.5"-3" to maintain good vigor and health. Healthy grass will have fewer weed and insect problems. Apply a "lawn specific" herbicide to kill existing broadleaf weeds. (Make sure it is for use on lawns or you can kill your grass, too!)
  • The generally accepted frost-free date in North Idaho is May 31st.
  • There is still plenty of time to plant. Just about everything can (or should be) planted now. (If you dream it, you can do it!)
  • Mulch everything; mulches help maintain a more uniform soil temperature, retain moisture, and reduce weeds.
  • Cabbage, green onions, leaf lettuce, rhubarb, asparagus, broccoli and strawberries can be harvested this month.
  • Protect developing fruit from birds by using vinyl netting.
  • Protect yourself and your loved ones from serious sun damage by covering up, or wearing hats and using a sunscreen. Remember, skin cancer is a reality, and we need to protect ourselves!
  • Remind yourself, as you are working hard in the garden, that weight-bearing exercise keeps your bones strong!
  • Enjoy this wonderful season, as it is short-lived in our area.
  • The time is now to make your garden dreams come true!
