Dealing with spring snows

I’ve often been asked whether or not emerging bulbs or other plants should be covered up when temperatures are dropping and snow is coming to town.  In many cases, such as the storm we just had in the Denver area, the snow itself is your best insulation for your plants.  As the snow covers the plants, it helps maintain a steady temperature near the freezing point at ground level.  If the air temperature drops further, the snow should help protect your plants from these lower temps.  You might want to consider covering plants when a cold spell is coming without snow.  Additionally, it’s good to watch for damage the build up of snow may be causing to shrubs and ornamental trees.  Gently knocking the snow off with a broom may help prevent damage.  Just don’t stand under the branches you strike!
