December Tips for nw gardeners

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.





As night temperatures dip, set up winter protection like cloches, cold frames, and hoops to extend the growing season for lettuces and other hardy greens.

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