So I will start by saying that in the last 2 years I acquired a number of pots...small to very large. I also state here that The large containers are HEAVY even those that I have not yet filled with soil. I do not have the space to move them indoors for the winter, nor the inclination to move all of them a couple if times a year. In my experience, many of the plants described as being suitable for containers are not. Additionally, given heat and direct sun, pot soils dry quickly and pots heat up roots. This requires a LOT of watering. In the winter, they are above ground and will freeze straight through. So, with temp & mosture extremes, I am looking for some discussion on what might live through all of that. I thought about just planting purple okra in several on the front porch as they could tolerate heat and dry. But that would treat them as annuals and leave the containers open in the winter.
On the other hand, a few other trees that seem to tolerate extremes come to mind. These are trees like siberian almond, yellowhorn, etc. Siberian almond is a looker, but the nuts can be bitter to toxic.
Anyway, I would love to hear from those in temp/ moisture regimes similar to mine who grow in large pots. Thoughts?
