Michigan Gardening To-Do List: December

Here’s your garden to-do list for December:

Seed Starting

  • This month is generally when we begin winter sowing, as long as the weather is consistently below freezing. Even if you’re not able to wintersow yet, you can prepare  your containers and make sure you have plenty of seeds and soil.
  • Sow pansies indoors this month so you’ll have nice-sized plants ready to plant out in containers in March.

 

Herb/Vegetable Garden

  • Some years, we are still experiencing mild weather, even in December. If we are, chances are good that you still have a few things, such as kale, chard, mache, and carrots growing happily. Continue to water and harvest as needed.
  • If we’ve had a good freeze already, it’s time to sit back and dream of next year’s garden!

Perennials

  • Once the ground has frozen, use fall leaves or other organic matter to mulch perennials that are prone to frost-heaving.

Bulbs

  • As long as you can still find bulbs in the garden center, you can buy and plant them in containers for a beautiful display next spring. Simply plant the bulbs, then place the pot in a protected location such as an unheated garage, covered porch, or garden shed. This is an excellent way to add color to your garden next spring and take advantage of end-of-season bargains!

Trees and Shrubs

  • If the ground hasn’t frozen yet, make sure that you water if we’ve had a long period of drought.

Houseplants

  • Winter is our houseplants’ time to shine. Make sure yours are watered regularly and are getting the proper amount of light.
  • Watch out for pest problems.
  • Consider misting your plants once or twice a day, since dry, heated air in our homes can stress houseplants.
  • Force some bulbs for the holidays: amaryllis, paperwhites, and  hyacinths are all classic bulbs to force at this time of  year.
  • If you’ve purchased a poinsettia for the holidays, make sure to water when the surface of the soil feels dry and give it a nice, bright location in your home.
