Update: This was my first olla experiment. The seedlings did great without any surface watering (except from the rain, which we haven’t had enough of—we’re in a drought.) I’ve filled the ollas with #rainwater about once every 14 days. Our temperatures have ranged between a low of 50°F at night to 78°F during the day. My #zinnias are usually are either too dry or develop powdery mildew when I hose water. So far, I’ve had neither problem. #gardening #OllasByOsa
