what is the best method to overwinter geraniums?

Answer 1

If they are in a pot put the flower pot in a brown paper bag, don't worry about watering it, put the bag in the basement and forget about it until spring after the last frost. Then bring it out and water it, in a short time it's revived and blooming again. I do this with all my geraniums. If you have them planted (not in pots) dig them up dirt and all put them in a brown paper bag, and forget them until spring then replant them and water. By the way if you want more geraniums all you have to do is cut off a branch, put it in a glass of water let it alone (make sure that the cut portion stays in water all the time) it will grow roots and you then can replant it and you have got another plant.
Good Luck

Bringing them inside is the best but if that is not possible, do as I do...I put them under the house, in the crawlspace. It sounds strange, but they go dormant, do not require water or much light.
I have 4 geraniums I have saved for the past 3 years. I admit they
look pathetic when I first take them out in the Spring, but within two weeks they are green and trying to bloom. I also do my mandavillas this way and have had great success.

Answer 3

I learned this on the t.v. a couple of years ago and did it with this elderly lady's geraniums. They came out great!

Take the geraniums and put them in a styrofoam cooler with a small amount of soil in the bottom that's been lightly watered. Put them in the garage, basement, somewhere cool for the winter. When it starts to warm in the spring, replant and enjoy for another year! You can continue to do this for many years I believe.
