My Mexican oregano has been happily growing outside in a pot all summer. I've even managed to harvest and dry some leaves. It has grown to about a foot tall and I've moved it inside already. I did put it in a small pot when I first received it and I know it will grow into a small shrub. It's probably about the size to now require a bigger pot. Should I transplant it now or wait until spring? It probably will drop some leaves over winter due to reduced sunlight.
