December Tips for nw gardeners



Feed the birds! Our feathered friends are grateful for extra food over the winter. We have several birdseed mixes to attract different species of birds to your yard. Learn more about attracting birds on the blog.

Hellebore, heather, evergreen grasses, and winter pansies add color and interest to the winter garden. Also consider shrubs with winter interest: twisty branches and colorful berries brighten the winter landscape.


Be sure to remove any dead annual vegetables from the garden and dispose of them the in compost bin.

As night temperatures dip toward freezing, set up winter protection like cloches, cold frames, and hoops to extend the growing season, if desired.

Cut back yellowed asparagus fronds to 12 inches and leave until early spring when you can pull the dead stems out.

Stop fertilizing most plants (exceptions include those that are currently flowering or flower in the winter) and cut back on watering, especially for cacti and succulents.

You can remove any wet and moldy leaves from the lawn now with a mover, blower, or rake.

Clean and check your mover to prepare for winter storage.
