This plant grows like a tree, only A LOT faster. There are soft thorns or hairs all over the trunk and branches. As the trunk gets thicker, the hairs begin to fade away. It has beautiful pink fragrant flowers from early summer until fall. The flowers grow in bunches on the branches. It grows throughout my yard, popping up all over. I have tried to dig it up, but it all has the same root system and does not live once removed.
Perhaps a Mimosa tree?
I have a Mimosa tree with a split in the main trunk at a Y. Is the proper fix a brace, or bolt the Y in place? Do I need to cut the bark at the split to help the bark to mend back together? I would like to save the tree from splitting the rest of the way and losing half or all of the tree. Plus, is there a disease going around for Mimosa that causes the sap to boil out and the tree to curl up and die? This happened to 2 of my mother's trees.
You can either bolt or tie the split together. It does not always work, but there is a chance it will. If you bolt it back together, avoid putting the bolt through the heart wood.
It sounds like the tree may be getting wilt. This article will help you with that:
I have a Mimosa approximately 10' tall, which has 2 branches and the fork has a small crack in the middle. I have already lost one tree to the winter and I want to protect this one. Should I try to seal the cut, and if so, what with?
No, sealing the crack can trap disease against the wound and will make it worse. Instead, try treating the wound with a fungicide, which will help keep pests away. If the crack is bad enough that you worry the tree may fully split, you can use bolts to hold the two side together and provide additional support to the crotch of the branches.
What do you do with the pods that hang on the mimosa and the wisteria trees? Can they be used for anything?
The only thing to do with wisteria pods is grow more wisteria, as they are poisonous, you cannot do much else with them. Here is an article that you may find helpful: https://www.gardeningknowhow.com/ornamental/vines/wisteria/grow-wisteria-seeds.htm
As for mimosa pods, make sure the pods are completely dry, like paper. They germinate easily without stratification (cold treatment). Plant the seeds in a pot of moist potting soil about 1/2 inch deep. Germination occurs in 10 days. As with wisteria, All parts of this plant can be toxic and should not be ingested.
I love the bloom of a mimosa tree but it seems to leave a lot of debris on the ground. Is the tree worth the mess?
NO, this tree is not worth the trouble! While mimosa trees have a pretty bloom, they are very brittle and very messy. Most people consider mimosa trees to be a weed. You probably will not find a mimosa for sale If you have access to one in the wild, tag it and dig after all the leaves have fallen. Dig a 10" rootball for each 1" in tree diameter.
We have several Mimosa trees growing at the side of our house, in an old untended flower bed, that need to be killed and removed. We recently purchased the home and would like to reclaim the flower bed, but would also like to remove the Mimosas in the mean time. Any help would be greatly appreciated!! =)
This article should help with that problem: https://www.gardeningknowhow.com/ornamental/trees/tgen/weed-trees.htm
Should we cut very low branches near the ground? Will that help the top grow better?
Yes, pruning off the branches close to the ground should encourage more growth higher in the tree. For more information on the silk mimosa, here's an article; https://www.gardeningknowhow.com/ornamental/trees/mimosa/growing-silk-trees.htm
