I have two large planters in my patio garden that have drainage holes in the bottom of the pot. I grow vegetables in them but they they need a little more attention in the watering department than the rest of my container garden that is planted in self watering flower pots.
I tried using these terra cotta watering stakes to get the drainage pots on the same watering schedule as the self watering pots with varying degrees of success. I think the watering stakes work better when I’m going to be away from the house for a bit than as a full time self watering solution.

I’m redesigning and adding more space to grow herbs and vegetables on my patio. Since I am removing and remixing the current potting soil with new in all of my planters, I figure it is a good time to plug the drainage holes in the green planters and convert them into self watering planters.
