Snow – should it stay or should it go?

It’s snowing here in Seattle – always a fun event, especially when we’re expecting up to 10 or more inches. I know…many of you laugh at our “big” snow, but the hilliness of Seattle makes driving in snow an adventure. (In fact, I’m supposed to be flying out tomorrow for a Connecticut presentation, and my flight’s already been cancelled and rebooked. Sigh.)

But what about the plants? This time of year people often ask whether they should leave the snow on their trees and shrubs. I covered this in December 2010 (and in a podcast in December 2011), but now I’ve come up with easily memorized advice:

If it’s light, leave it – if it’s heavy, heave it.

Light snow helps insulate trees and shrubs from winter dehydration, but heavy snow can permanently bend or worse, break, tree and shrub branches. Use a broom or rake to knock heavy snow off branches.

Bending is bad…

…but breaking is worse.

  1. Linda–

    I feel for you. We had only a couple of inches here in Portland, but it was so wet and heavy that almost all the evergreen trees and shrubs in our garden were bent double–not a pretty sight. And I learned one painful lesson: If you have a loquat covered with snow, DO NOT TOUCH IT! The branches are unbelievably brittle, and you will only do more damage if you try to knock the snow off.

  2. I thought about knocking the snow off my shrubs, but by the time I got out there, the rain had already done most of the work.

    In Raymond, we have had cold icy rain for over 24 hours now. Which means we also have about 6 inches of slush. Ugh!
