I love my mimosa tree. I pulled out of my mother-in-law's hedge row about 10 years ago and planted it over my children's swingset. It grew quickly and provided shade and beauty to my backyard. It has thrived until the last few years when the longer limbs have started to break off from the weight of the foliage and flowers. This has rarely been associated with high winds. I am afraid that it will die from all of this breakage. It has already become slightly one-sided, but the limbs continue to grow longer and longer!
Not only does this tree remind me of my children's younger days, but also mine. There was a mimosa tree in my yard which was just perfect for a little girl to climb and perch to read. I seem to remember my dad pruning that tree. When and how should I do that? Is the pruning for the purpose of preventing the limbs from breaking?
As for it being messy or a pest, all it takes is planting it where it won't shed on patios, porches, driveways, and mowing under it regularly. Just pull up the babies as soon as you see them from flower beds, etc.
BTW, I live in middle TN which until this year with our outrageous amounts of rain (and floods) has had some severely dry summers. Could the lack of rain have caused th breaks? I haven't had any broken limbs this year!
Mimosa is a fast-growing tree and that worked out well for you for shading of the swing. But often, fast growing trees like mimosa have brittle wood and the branches of mimosa break easily. I can imagine the rain contributing to breakage by encouraging rapid growth or weighing down branches.
Mimosas are somewhat short-lived (10-20 years) by nature so, if your kids are grown, the tree may be reaching the end of it's natural life span.
Your tree certainly looks lovely in the photos so I hope that it rebounds. Best - Sarah
Mimosas in OKC are weeds.
They don't mind heavy clay, high winds, drought, rain, snow, or being cussed at.
They are, like the Oklahoma Redbud, fast growing and relatively short lived.
However, once pruned back, both small trees usually sprout new limbs and do fine.
