Did you know that 40% of the food produced in the US is wasted? Here are some tips to help you reduce this number. Shopping with a list can be useful in reducing impulse purchases or buying more than you need. Shop your fridge first. You may be surprised what you bought last week and forgot about. Freeze foods that may spoil quickly for use in a later meal. Learn how to store fruits and vegetables properly. By following these guidelines you’ll save money (due to less wasted food), reduce your overall waste, and help ensure all of the transportation, fuel, labor, water, and other resources that went into growing that food isn’t wasted either.

What is composting and why should I do it? Composting can be practiced anywhere... in your backyard, at work or school, even in an apartment! Learn more about how and why you should compost!
An easy and fun way to reduce what you throw into the trash is to start composting. Simply take your “green” nitrogen-rich items like fruit and vegetable scraps, eggshells, coffee grounds, and tea bags, mix them with your “Brown” carbon-rich items like dried leaves, wood chips, straw, and/or shredded paper, add water and mix it all together. In as little as a few months, you’ll have a beautiful, rich soil amendment in the form of compost. Compost is able to hold more water, is loaded with beneficial nutrients and microorganisms, and reduces or eliminates the need for chemical fertilizers. The County of San Diego offers discounted compost bins to unincorporated residents year-round. To learn more visit R1Earth.org.

of turf grass. San Diego-appropriate plants can reduce water use by
70-80% compared to turf grass. The County offers educational and
financial support to residents wanting to make this change on their
properties. Check out this video about a large landscape project recently
completed at Rancho San Diego HOA. Then go to our website to learn how you can do this too.
