I want to grow herbs on my lanai which is pretty narrow. I was wondering if I can grow herbs successfully in small 5" pots. I wanted to have 2 or 3 of these ikea socker plant stands (each with 13 pots) to have a wall of herbs. These seem really small to me and I'm assuming they would need to be watered daily in the florida summer heat...which I guess I'm ok with. But is this too small for most herbs to grow outside in florida heat?
I didn't really want to have larger planters sitting on the ground due to a lack of space.
