It really works!
I have to admit, I was skeptical. I mean, irrigating plants by filling a terra cotta jug buried nearby? But I can't argue with success. The Olla is simplicity itself, and it really works. I use it to water an orange tree in a planter box, checking the water level inside the jug every couple of weeks and topping it off when needed. No hassle. No wasted water. And my orange tree is happy. Olla rocks!
