Hypothetical lawn question:

Factual Questions
1

The random things that come to me when I’m driving…

My question is this: <hypothetical situation> Water is being rationed in my city. I have exactly enough to cook/drink/bathe, etc. However, I have none to water my lawn. Hey, looky, I can use the water from my bath/washing machine to water it. However, will it be best to divide my lawn in to a number of equal sized sections, and use all of the day’s water to water that small plot of lawn, then rotate each day? Or would I be better off evenly distributing the day’s water over the whole lawn? Assume that I’m trying to keep the largest possible percentage of my lawn alive for a certain length of time. a month? a year? Would the time matter, as long as I got around my yard with the section method at least once? </situation>

Quick strike on the answer. Depends on the size of your lawn. Safest is to catch the rinse water of the washer from the hose and use that, spread around in cycles. Grass can easily handle up to a week (or 2 depending on species). The saop/detergent may not be healthy from bath water or the actual wash, OTOH I don’t know if it’s harmful.

Yes, go with the cyclical watering-in-sections plan. Frequent waterings using smaller amounts of water are not nearly as beneficial as less frequent but ‘deeper’ watering, which encourages rrot growth.

Make that “root”, not “rrot”.
