Spring Garden Calendar

Here’s your Spring Garden Calendar to give you a little nudge.   Get out and enjoy the sun, in between storms.  You’ll feel so refreshed once you begin your garden cleanup and start communing with nature again.  Its been a long, cold, wet winter.  The fresh air will change your mindset!

Remember the purpose of a ‘messy’ garden–all those dead leaves that have blown in, all the dead branches and leaves from your perennials are providing protection.  They provide habitat for wildlife, they hold in the moisture and they insulate your plant from the changing weather conditions.  Remember, a messy garden is a sustainable garden!


  • Start outside, all your cold-weather vegetable crops like peas, kale, lettuce, broccoli, onions, radishes and carrots.  And your sweet peas too!
  • All your summer-growing seeds indoors under grow lights at the end of March or outdoors under cold frames. Keep grow lights about 2” from the top of your plants to develop sturdy, thick stems.
    • Put your starter pots on an old electric blanket to provide bottom heat to give your seeds an extra boost and eliminate fungus that often starts on seedlings and kills them when conditions are too moist.
    • (Take a look at the seed starting videos in these posts).

  • Clean out perennial beds. Remove a majority of the dead material, leaving the bottom-most layer to add fresh mulch and nutrients to the soil.  Remember, there will still be hibernating beneficial critters in that mulch, like worms, dragonfly eggs and a drowsy bee or two.
  • Divide any perennials and/or transplant those that have self-sown.  This includes iris, ornamental grasses, and berry plants.  Remember to add a sprinkle of bonemeal and alfalfa pellets to your plants’ new home.


  • All deciduous trees, except maples. First remove water spouts, suckers, crossing, weak and broken branches. Next, remove inside branches—so a bird can fly through. Remove fruit spurs growing on inside branches.  You are opening the center of the tree so the sun can ripen all the fruit.
  • Spring blooming shrubs such as quince, lilac and forsythia immediately AFTER they bloom.  And please, prune for a natural appearance, you’ll be much happier with the beautiful natural fountain shape of these shrubs.
  • Roses after April 15 (tax day).  You know we are still going to get a couple more big freezes.  When you prune, it stimulates the plant to send out new growth.  By pruning too early in the season, all that new growth will get frozen.
  • NOTE: Always prune to a main branch or to a branch (or bud) growing the direction you want the shrub to grow


COMING SOON:  A special premier membership section with new tips from all the gardeners and growers interviewed in the podcasts.  New audio and video accompanying each tip, to make your gardening easier and more productive.
