We know about self watering containers, but how about self watering garden beds?
|Ollas before they were buried, placed about 4 or 4-1/2' apart in my beds.|
|Buried up to their chins and filled with water. Now just waiting to see how the plants like it!|
From what I've read, olla irrigation has been traced back as far as 4000 years in China, and is thought to originate in Africa. It is and has been used by cultures all over the world.
Water tends to seep through the wide, bulbous part of the pot which is deeper in the soil, not through the neck, so the surface soil stays on the dry side. The surface soil would act like mulch, reducing evaporation. With the surface soil dry, it is said that fewer weeds will germinate. I will still mulch deeply, to keep as much moisture in the soil as possible, and keep the soil life happy and thriving.
