I can cover my spring greens but all the trees blooming are going to be gonners. This happened a few years ago and we had a horrible apple harvest.

and we were getting a freeze was 1) cover what could be covered with a sheet or 2) wet all the plants down. That is the best that I know to do.

I just bought 24 hosta plants earlier this week. Thank god I didn't plant them. Into the garage they go.

I'm trying to finish a new set of raised beds and it snows every damn weekend!

this picture shows hoops to support the row covers, but you can also drape them over plants. They are light weight, allow in air and light, but protect down to 20 below.

I've got a lot of seeds in containers (Winter Sowing). I *think* they are ok, even tho freeze is expected tonight, but to be safe, I wrapped the containers in row covers.

Yesterday I bought 6 perennials, and put them in the garden in their pots, and covered with row cover.
but now I have to put them under shelter, bec it is going to rain/snow.
and that will cause the row cover to be pressed down on the plants, which may be ok, or may not.
