I recently set up automated watering in our backyard. The gutters on our garage fill a rain barrel that has a timer attached to a soaker hose that runs through the garden. This is especially nice solution because (1) there’s no running water on that side of the house, (2) the rain water is free, (3) I can spend gardening time on other tasks, and (4) the chipmunks that used to love to hide in that downspout have to find another home now. It’s not fertilizing like in this article, but it wouldn’t be hard to add if we wanted to.
If there’s any interest, I might make a video of this. Please let me know in the comments.
Update: I posted a video on YouTube.
