I was just looking for others’ experience with these plants/trees. Like “plant it here, but not there”. “Make sure you do XYZ every season”. “I use X to do A, and it worked really well”.
I was most concerned with planting something that would “take over” and cause problems with other parts of my gardens & pasture, etc.
The mimosa grow very quickly and my honeybees love them. They are semi-difficult to contain and do best on the bank of a pond or a low spot that holds some moisture. They will grow away from water, but a bit more slowly. The wood is very green and flexible, so they tend not to break in storms. I do nothing to care for them except trimming low limbs to encourage them to 'umbrella'.
I have only 1 catalpa tree. It is kind of an oddity, so I keep it. I don't do anything to care for it. It is close to my garden and has never caused a problem that I am aware of.
