Conserving Water by Square Foot Gardening

I received some more counsel from Mel Bartholomew about WHY we use a simple bucket of sun warmed water for the Square Foot Garden. Here's what Mel says-

"Here’s WHY ? The  water right from a house faucet is cold, and filled with chlorine and any other chemicals the town uses to treat and purify home water.  I learned this when raising tropical fish at home.  You never fill a new aquarium tank with tap water and then put the fish right in. They will turn belly up and die from the cold water and 

chlorine.  Best to let the filled tank sit overnight and all the chlorine will evaporate into the air and then the water will be room temp and chemical free for the fish. (See now why we use a bucket of sun-warmed water instead of hosing  down our SFG?) 

 Same thing goes for your precious plants in your SFG. That’s why the official-correct way to water a Square Foot Garden  is from a bucket of sun warmed water.  Besides you are using only 10 % of the water needed to water a traditional row garden and best of all, your hand watering gets you close to your plants, and just like children, you are nurturing your plants.

 In addition, sprinkling the plant  tops  is just wasted, unneeded, and sometime s detrimental   so in SFG, we hand water with a cup of sun warmed water right to that slight saucer shape you created at the base of the plant so all the water goes right to the root structure where it is needed.     Doesn't  all that make sense?

 No other method of gardening tells you that. Stick with SFG and you can’t go wrong."  -Mel
