Has anyone here used ollas (terracotta irrigation pots) for watering their garden? I’m considering getting a few for a small border (about 2x1 meters) with hydrangeas, but I’m curious about real-life experiences. Do they actually keep the soil consistently moist, especially during warmer days? Also wondering: - How often do you end up refilling them? - Do they make a noticeable difference compared to regular watering? - Any downsides I should know about? Would love to hear your experiences before I buy a couple! submitted by /u/Notsocheeky [link] [comments]
