I Planted a Mimosa/Silk Tree 4 Years ago in NE Ohio Help!!!
Hello, I planted a Mimosa tree in a city enviorment in NE Ohio 4 years ago. I knew it was not good for our zone 5b, but I saw one in someone elses yard growing up and was still there to this day and is beautiful!
I was a little more naive 4 years ago as I am now. I planted it on the south side of my home just a couple feet away from my foundation in something close to a 12 gallon pot with four nice size holes in the bottom. I also put a thin layer of gravel in the bottom of the pot. It's first year in the ground from a seedling it grew to about 2 feet tall and died to the ground after the first winter. The second year it grew 6 feet tall single trunked lead and only died about about 6 inches after the winter. Then the third year the new growth incased the 6 inches of dead and split into 3 different branches right above the 6 foot mark. The branches all grew as wide as the tree is tall. So now this year at the 4 year mark I see the tree coming back to life with NO dieback at all. I have today a little taller than 6 foot tall Mimosa with a 12 foot spread! The Mimosa I am scared laughed at my pot and probably grew out of it? I thought back then I could keep it under control and maybe have an ornamental tree that would make the neighbors jealous.
They sound so scary now since I have read up on them more. I am scared it could damage my foundation. Also does anyone think since it has split that it will not get any taller? My overhangs are about 4 foot away from it's top. It has never flowered but I think it is going to this year. If I should get rid of it I am thinking maybe I should before then so I do not fall in love with it! It's a shame it has grown into a perfect height for the spot and could even get a little taller and wider and be no problem, but I am worried that it will get huge or cause damage. I will try to take some pictures shortly of it and add them on here, but the next few days call for rain.
Any advice from northern gardners would be very much appreciated on what I should do!!! Is there any way of pruning it correctly to keep it under control if it gets out of control???
