Alameda County Water District

California is experiencing drought following two critically dry years locally and statewide. A few tips to save gallons of water per day include: shorten your shower by two minutes, turn off water while brushing teeth, wash only full loads of laundry and dishes, cut back by one load per week, replace your lawn with water-efficient landscape, and install a ”smart” irrigation controller. Some of these tips save more than five gallons per day!

When to Harvest Garlic
Grow Organic

After your garlic has produced scapes (hardneck varieties), your bulbs are really starting to size up. You can start cutting back on the amount of water they are getting, but you don’t want your garlic to dry out. Once your garlic has a couple of dead bottom leaves you will want to stop watering. You can dig your garlic in a couple of weeks. Read more.
