December 2020

Here are the things that you should have done before we had all the snow! Just in case we get a mild spell and some rain to wash away the snow, here are a few things you still can do.

  • I usually recommend a little last-minute deep watering, but with all the rain this year we should be OK until spring.
  • Loosely wrap evergreens and especially rhododendrons with burlap. It is better to use 3 tomato stakes and make a triangle of burlap 6” away from the plant. The objective is to break the wind and shield it from the winter sun.
  • Protect young trees and shrubs from rodents with spiral plastic wraps. I know they are ugly, but they are white to reflect the sun and minimize sun scalding.
  • Wash all your garden tools. Wipe the metal parts with a cloth soaked in 3-in-1oil. If you really want to be fancy, wipe the wooden handles with boiled linseed oil.
  • Make sure you have stocked up on firewood for the winter.
  • With all the snow cover that just arrived, the ground will not be frozen yet. That means, if we get a break in the weather, you can still plant those spring bulbs that you forgot in your garage or basement.
  • I’ve planted tulips on Christmas Day in my garden by the sidewalk in downtown Toronto. An elderly gentleman passed by and asked me, “Whatever are you doing?” I told him “It’s an old Hethrington tradition. I always plant tulips and daffs on Christmas Day”. He shuffled off shaking his head, but there were blooms in April. So, stick them in the ground before it freezes.
  • Inside, check to see that your house humidifier is maintaining the humidity at over 40% to benefit both house plants and people.
  • Put lots of garden tools and garden books on your Christmas list!
  • Order seed catalogues and start dreaming about SPRING!
