    Unfortunately, the root system on this tree is considered invasive in most areas, here. I would avoid putting them within 50 feet of anything that you don't want destroyed.

    When you do find a suitable spot, this article will help you to care for the tree:

    Unfortunately, this looks to be more related to overwatering, than underwatering. When moved to a larger pot, much of the soil is uncolonized. This will mean less evaporation.

    I would treat with a fungicide, and be sure to let the soil dry out, thoroughly, down to about 1/3 of the way down into the container, at least, between waterings.

    You can cut the smaller one off at the ground. It may grow back but just keep cutting it off at the ground. They are so close, it may disturb the roots of the larger one if you dig it up, as you say.

    Likely, they will be fine! They may change shape a little as they adjust to the new growth, but they shouldn't suffer too badly.
