We made some progress on the irrigation for the back planter this weekend.
We were able to replace ten sprinkler heads that spit out 510 gallons per hour ("GPH") (10 heads, .85 gallons per minute) with four drip lines (soon to be five) totaling 30 gallons per hour. I actually had to walk out and count the number of emitters right now, as we have 1 GPH emitters on most plants, with some soaker hoses on others (I guessed 3 GPH on the soaker hoses, they aren't very long). That's a 94% decrease in our water for this area. Granted, it will increase as we put in more plants and they get bigger, but I don't believe we'll surpass 200 GPH for this bed. We plan on packing a lot of plants in there and making them as drought tolerant as possible. This is where we put the Jerusalem Sage and Lion's Tail. That potato vine in the background of the bottom picture doesn't have any irrigation going to it at the moment. I may add an emitter as it gets hotter, but we'll wait and see.
For full disclosure, I went to Toro's website and looked at what they said the output of a 180 degree sprinkler head was, as all 10 of ours were that. I may even be low, as our sprinkler heads were at least 13 years old, and I took the specifications of the latest and greatest.
Running all of the drip line took about three hours. It probably could have taken a little less, but it was hot, so there was beer involved. And, there aren't any leaks, so that shows you how damn easy it must be if a drunk can do it!
Being in Southern California, water is our most precious resource, in my humble opinion. I've even done some research that shows it doesn't pay to recycle paper here, because of the extraordinary amount of water it takes to turn recycled paper into another usable product. Apparently, to remove all of the toxins in the dying, bleaching and whatever else they do to it process. I'm not done with that research, yet. Another post.
In the meantime, I hope you'll be motivated to at least look into drip irrigation. I'll even be happy to come out and help. For a price, of course. Unless you're in London, in which case I may come out for Spurs tickets!!!
