Here are the 35 tomatoes in wall of waters. You can buy them at your local nursery or order them through the internet. They are an invaluable tool for Spring as they act like little greenhouses or cloches to help protect your tender plants from cold nights and the wind.Be sure you fill them up in the morning so they have all day to heat up. Then they will give off the heat at night and keep the plant warm.
To set them up, put a 5 gallon bucket over the tomato (the tomato must fit inside the bucket) then slide the wall of water over the bucket and take a hose and fill up each cell in the wall of waters. When done slide the bucket out and the wall of waters support themselves. If your plant is taller than the wall of water, you can still use it but will need a friend to hold the wall of water as you fill up each cell. Sometimes the wall of water (WOW) can partially collapse under heavy wind. In that case put some bamboo posts inside the edges of WOW to help support it. In a few years, you might get some leaky cells. I take one of my leaky WOW and cut off a good cell and insert it into the leaky cell and fill it up and it works. I only use wall of waters in early spring when it is still cold at night. Be sure to take them off when the plant starts to get crowded inside of the wall of waters, usually in late May or early June.
