Garden Winterizing Checklist

Garden Winterizing Checklist

By Shannon McGloin

It’s hard to believe that it’s this time of year again – November. The leaves have fallen, Halloween has passed, and the holidays are in our reach. Wasn’t it just Canada Day? Weren’t we just starting to get our hands dirty in the soil, planting fresh begonias, callies, and petunias? Unfortunately, we can’t change the inevitable, and it’s time to clean up your garden for the winter. We’ve put together a list of things to take care of before the snow flies.



It’s advisable to apply a thick layer of straw or mulch around the root system of newly planted trees, shrubs, and perennials. This will insulate the plants’ root system and increase survival rate


  • Apply tree guards – this is important in the prevention of bark splitting from freezing and thawing, and also protects against animal damage.
  • Rake leaves, and dispose of those that have any fungus problems


Burlap any new cedars – we did a demonstration on our Facebook page, check it out here:


Most pruning is best done after a plant has flowered, but light pruning of Hydrangeas may be necessary to prevent breakage of heavy limbs from the snow.


  • Apply fall fertilizer
  • Top-dress and dormant seed


Annuals & Perennials

  • Remove all annuals
  • Cut back any perennials that:
    1. Have no winter ornamental value
    2. Have any disease problems (i.e. powdery mildew)
  • Remove any weeds so they don’t have the chance to overwinter



Plant spring and summer-flowering bulbs, as well as garlic for next year’s harvest.


You can find all the products needed to put your garden to bed at the greenhouse, located at 2500 Southview Drive in Sudbury, Ontario.
