The weatherman in our area is calling for a hard frost tonight and it will take these great blue morning glories. They grow just down the street from me every year and I marvel at how they trained them to shoot skyward.
I have brought in my cactus and a few other plants and will nurse them through the winter. I pull my geraniums every years and shake off the dirt and put them in a brown paper bag and place in basement until spring, when I bring them out and plant them again. Few know that you can do this.
