Raised bed gardening article - current issue CSMgreenspun.com : LUSENET : Countryside : One Thread
Reading in the current issue, there is an article by Richard Rock about raised bed gardening. I am having difficulty with the second paragraph on page 53 where he is preparing the bed for early tomatoes: "dig a trench eight inches long and five inches deep. Put a "wall-of-water" over the trench with its cells full of water. My question is: What is a what is a wall-of-water and what are the cells I am filling full of water? I like the square foot gardening method, but I'm a little lost on the issue of this entire paragraph.

A "wall-o-water" is a commercially made collapsible plastic ring with cells that you fill with water. You put it around a plant to keep it warm.
They can be seen in many seed catalogs for sale.

Wall-O-Water is a plastic flexible thing that stands about 2 feet and has channels or cells that run vertically on the wall. It is used to start and keep young plants warm in cooler climates. Personally, I like to use plastic milk jugs and cut the bottoms off. I leave the top (cap) off the jug too so it doesn't get too hot in the little green house.
