First off: what's an olla? (pronounced oh-la)
According to wikipedia, An olla is a ceramic jar, often unglazed, used for cooking stews or soups, for the storage of water or dry foods, or for other purposes. Ollas have a short wide neck and a wider belly, resembling beanpots or handis.
There you go. It's a pot, basically, which in this case is used to water the garden in an efficient and water-saving way. My friend Ken Keppers, a local potter in Turtle Lake, made three of them for me which is so exciting. I took advantage of the cloudy and rainy weather we are having to go out into the hoophouse (which can get up to 150 degrees Farenheit on a sunny day, whoof!) to plant my pots in preparation for tomato planting.
First off, digging the planting hole:
Just a word to the wise: put a cover of some sort over the opening. Otherwise, it becomes an unattractive slurry of slugs and bugs that fall into a watery death trap. I'm sure it's nutritious, but it gets stinky in a hot space.
