We have a lot of sumac in our yard. Can we feed them? Miracle grow hose application?

Thank you for writing.
First, I am going to assume that you can tell the difference between sumac and poison sumac. Here is a refresher. https://www.thespruce.com/poison-sumac-vs-staghorn-sumac-4772349
Sumac spreads quite aggressively underground. It is well adapted to Minnesota. Your patch is thriving. There is no need to provide further nutrients.
