Some people are using tap water to spray their gardens, but this can become expensive after a while and for those participants with a well it is unsustainable simply because with no rain the well of course gets low to and can deplete the family’s source of water for their home. A few of our participants have been packing or pumping water from a near by stream. Although very labor intensive, this is the most sustainable and practical way (other than a rain barrel) or if a rain rain barrel is unavailable or has been emptied .
We have suggested using a rain barrel to catch the run off from the roof of their houses. It is important to try and get these set up in the early spring when the rain is more plentiful. A rain barrel can be constructed fairly simply and at a reasonable cost. I have added a link that teaches 3 ways to make a rain barrel for less than $10.
So until mother nature decides to give us a hand and provide us with some much needed rain try and keep your plants watered with what ever method you have available.
