I have built a wooden box for planting, but currently it still sits empty in the middle of all potted plants. It is currently an empty space in my patio garden.
On the other note, since the start of my patio garden, there hasn’t been an increase in water usage in the apartment at all. Between the three roommates, the excess of water at the beginning of each shower (while waiting for warm water) has been collected to water this garden. This is one way that everyone can do in your effort to deal with the drought in California.
