I recently "planted" two ollas in my vegetable garden. If you are wondering what an olla is, you may need to know that the pronunciation of the word is oy-ya. It is a Spanish word that means pot.
This is a view of the squash bed from the other direction. The plants on this end are not as healthy due to pill bugs munching on the stems. The smaller plants allow you to see how the olla is buried and how the plants are oriented around it.
Ollas are supposed to last several years. Any freezing and thawing during the cold winter months will probably be the hardest on them. As cold temperatures approach, I will stop refilling them and leave them the ground through the winter.
For your viewing pleasure, here is a clip from Central Texas Gardener about ollas.
And here is another clip showing how to make your own olla. If you search the internet, you can find several plans for making your own ollas.
Elsewhere in the vegetable garden, I have a patch of black eyed peas growing on my homemade cattle panel arch. The taller plant among the black eyed peas is my only surviving green bean plant. I planted green beans before I planted black eyed peas and the pill bugs mowed down all of the others within a couple of days. Fortunately, they do not seem to care for black eyed peas. I hope that one bean plant produces a lot of beans. There are a few more squash plants to the right of the beans.
