It’s starting to get colder, and soon the snow will start to fall. This is great for the plants, as snow is an excellent insulator. But what if it doesn’t snow? What if it’s just really cold for awhile, first? Straight – up cold can be devastating for perennials, especially tender ones that are at the limit of their cold hardiness, or new ones that got planted late.
What to do? Well, it’s better to hedge your bets and give your most precious plants some protection than just hope that there will be snow. This doesn’t mean anything too complicated – just cover the crowns of the plants with salt-marsh hay, or evergreen tree boughs. (You can supplement these later with boughs cut off your Christmas tree, if you have one.)
Roses can also benefit from a little cover. Plastic fencing or chicken-wire, wrapped around them, and stuffed with leaves works well. You can also buy things made especially for roses, but then you have to figure out where to store them the rest of the year. But in the end, it’s up to you. Anything you can do to help the plants will be greatly appreciated by them, and they will reward you in kind in the summer.
