@LibraryFinch I originally used terracotta pots, which seal from soil and roots pretty quickly, but now I just use plastic 1 gallon pots because they're free and the threat of plastic is smaller than the threat of drought. I've found that if I start watering the pots early, the plants' roots train down deeper and they're set for much less watering, come drought-time. They don't sleep out slowly like a terracotta olla, but they deliver water down deep where it can't evaporate. No plugging needed.
