A potted hydrangea
I live in Southern Indiana. Daytime temps are in the 50s right now. No frost yet?! I have a repotted hydrangea that I got for Mother's Day. Couldn't plant it in the ground as I had siding put on my house. Figured it would be trampled by workers. Flowers were a dusty pink color. It's about 1 foot tall. Not sure what kind it is. Should I transplant it into the ground, leave it in the larger pot over the winter outside or bring it in for the winter? Or do you need more info ?
You have several different options here, but the good news is that it is fairly easy to give these winter protection.
