I'm considering experimenting with an olla irrigation system this year by burying some clay pots in my garden for my tomatoes and peppers. Since I have limited space (16 x 24), part of which is already taken up by perennials like asparagus, garlic, and horseradish, I'm wondering if there's anything specific I should know before getting started. I'd like to group my plants in fours with a pot in the center, but I might have to adjust that plan depending on the size of the pots I use. Also, apart from unglazed clay pots, are there other inexpensive options out there? Has anyone here tried ollas? What are the pros and cons?

I've expanded my olla systems using some bought ones and they've been fantastic! The only time I water directly is during extreme heat, otherwise filling the reservoirs every few days keeps my plants thriving. They really shine in hot conditions. I'd definitely keep experimenting with them!
I've tried using an olla system, and I think it really helps with watering! I found that my plants had roots wrapped around the pots, indicating they're definitely drawing moisture from them. For a budget-friendly option, I've stacked two clay pots and glued them together to create my own ollas. You could also experiment with using wine bottles, either directly or with clay spikes attached.
I set up a simple DIY olla last year and it worked wonders for my young tomato plants. Just a terracotta pot with the bottom sealed and a saucer on top did the trick. I recommend starting this experiment, especially if you're focusing on younger, leafy plants, as they might benefit the most from the additional moisture. Perennials like garlic and asparagus usually have more established roots and may not need the help as much.
