cheap, easy, mobile drip irrigation.
Drip irrigation is much more efficient than sprinklers
You need an empty jug and a pointy thing
Step 1: Poke a Small Hole in the Bottom of the Jug
I found that the corner opposite of the handle works best. Start with a small hole; you can always make it larger later.
Step 2: Fill With Water and Set It Next to a Plant
Set the jug on the uphill side of the plant. Loosen the cap.
Pay attention to what time it is (not really necessary)
Step 3: Come Back in a While and See How Much Water Is Left
Make the hole bigger if it's too slow.
I got about a gallon per hour and a half.
