What are water walls?
Water walls are a type of plant barrier which is used to protect plants against extreme temperatures. They consist of small holes or channels running through the soil, with one end connected to a larger body of water (or drain). These barriers have been found useful in protecting tomato plants from heat stress during hot summer days. Water walls can be made using various materials such as rock salt, sand, gravel and even concrete.
The purpose of these barriers is not only to keep plants cool but also to prevent root rot and other diseases. Water walls can be used in conjunction with other methods such as irrigation, aeration, and fertilization.
However, they are most effective when combined with these techniques.
How do I make a water wall?
There are several ways to create a water wall including the use of rocks or stones; cement; plastic pipe; or even just plain old dirt!
You will need to choose the material that is best suited for your situation. There are many different types of rocks available, so it’s best if you start out by finding some suitable boulders.
You could also try digging around the area where you live and see what kinds of rocks might be nearby.
You will need to place the rocks in a line so that water can flow through them. Be careful not to create any gaps between the rocks, as these could pose a flood hazard.
The size of the gaps or holes are not really that important, so don’t worry too much about being too fussy. Just make sure you use enough rocks to cover the entire area where your tomato plants will be placed.
