How to Grow Geraniums Over the Winter

By: Julie Day

Geraniums are one of the most popular container and garden plants. You just can’t beat their bright colors and sturdy, well-shaped foliage. At the garden center, geraniums tend to come in larger sizes, which make them more expensive than other summer annuals.

Unlike many of their peers, geraniums can easily be stored over the winter and enjoyed again next year. So if you hate to see your lovely geraniums killed by frost this fall, here’s how to go about overwintering them indoors.

Methods of Overwintering Geraniums

There are three ways to make geraniums last through the winter:

  1. Overwinter inside as potted plants.
  2. Store the dormant, bare roots.
  3. Propagate cuttings to make new plants.

Geraniums as Indoor Potted Plants

The easiest way to keep your geraniums over the winter is simply to bring them inside. Here’s how to go about it:


  • Before the first frost, carefully dig up your geraniums and pot them in 6”- 8” diameter containers, with lightweight potting soil. If yours are already in containers, you get to save a step! Don’t bother keeping any that look unhealthy or diseased.
  • Cut the plants back by a third to a half. Save the cuttings and root them to make more geraniums!
  • Water the pots thoroughly.
  • Place the pots in a bright, cool spot. Geraniums overwinter best in a sunny window with temperatures around 60° F. They don’t do well in dark or overheated rooms.


  • Over the winter, pinch back the tips of new shoots to help them branch out.
  • Water the cuttings whenever the soil becomes dry.


  • Fertilize your geraniums in mid-spring.
  • Move them back outdoors after all danger of frost has passed. You can keep them in their containers, or plant them back in your flower beds.

Geraniums are perfect for window boxes, but can’t survive freezing weather.

Overwintering Bare-Root Geraniums

Geraniums have nice thick roots and stems that allow them to survive winter dormancy if kept above freezing. You can also allow geraniums to go dormant and store them as bare roots. Follow these steps:


  • Before the first frost, carefully dig up your geraniums, and shake all the dirt off the roots.
  • Put them in unsealed paper bags, or hang them upside down, and store in a cool, dry place around 50° F (a garage is perfect).


  • Every month or so, pull your geraniums out and soak the roots in water for a couple of hours.
  • Allow them to dry before storing again.
  • The leaves will eventually all fall off, but the stems should stay firm. If the stems shrivel up too, the plant is likely a goner!


  • Inspect your geraniums early in the spring.
  • Remove any shriveled sections.
  • prune them lightly, cutting off any dead tips.
  • Soak the roots for a few hours in water mixed with a little plant food.
  • Plant the roots in potting soil and water thoroughly.
  • Place your potted geraniums in a sunny window, or under a grow light. They might take a few weeks to wake up and start growing!
  • After all danger of frost has passed, you can move them outdoors.

Geraniums can also be rooted from cutting using rooting hormone.

Propagating Geraniums From Cuttings

The last option is to say goodbye to your original geraniums and nurture new ones grown from cuttings. Here’s how:


  • Using a sharp knife or shears, cut pieces about 3”- 4” long from the ends of the branches. The best cuttings come from the terminal end (the very tip end of the stem), rather than a side branch.
  • Pinch off the leaves from the bottom third of the cutting, and remove any flower buds.
  • Dip the bottom of each cutting in rooting hormone, making sure to dust the wounds where you removed the leaves.
  • Plant the bottom third of each cutting in peat moss, sand, or perlite. You can use individual pots or plant them together in a tray (plastic planting trays are available with a clear cover to hold in moisture).
  • Place the pots on a drainage tray and water thoroughly, ideally from the bottom up (fill the tray with water and allow it to soak to keep from washing away the rooting hormone).
  • Cover your pots with clear plastic, or use the cover that came with the tray.
  • Place in a bright window out of direct sun. Your cuttings need light, but they can’t handle the direct sunshine.


  • Keep the planting medium moist by soaking in the drainage tray, or removing the plastic cover and lightly misting the plants and soil.


  • Your cuttings should root in 6 to 8 weeks. By early next spring, you can to move them to their own pots with regular potting soil.
  • Fertilize your new plants, and pinch back the new stems in order to make them branch out.
  • Move the pots to a sunny window until time to plant them outdoors.

    Hi there……saw all of these questions and saw no answers after the comments!! Well say, I had my geranium on the unheated porch all winter..don’t think it froze for long, if at all. Here it is early April in the NE, plant is very green, some “dead leaves and stems” which I have removed. Looking kind of long and leggy!! What shall I do to save this beautiful red geranium? Thanks for sharing a response with all my friends here with questions!!

    We had a very cold night that the weather men completely missed coming, and it froze all of the geranium stalks that were out of the ground and exposed. Some were in pots around the pool and some were in the ground. If I prune off the dead stalks, is there any hope that they will re-leaf from the roots or should they just be dug up and pitched. The several that I have dug up to check, have roots that seem alive and not limp strings. It got down to about 26 when it was not even suppose to freeze. Thank you

    I live in the North of England and the answers/advise I have seen are for America. Winters here in the North are cold. Do I cut them now or in the spring? They will winter in a cold greenhouse.

    Will the blooms be as big next spring if I succeed in over wintering my geraniums? Thanks

    Do geraniums “require” a rest period? We have a beautiful geranium (one plant that I just cut off 24 large blooms). We live in the Midwest but go to the Phoenix area over winter and I’d like to take it with us. What special care is necessary?

    I live in zone 6, and have a potted geranium plant that used to belong to my brother, who died in his mid 30s in 1995. Hard to believe huh? After my brother passed, my father took up stewardship of the plant, keeping it in a sunny basement window all winter, watering it regularly, and bringing it outdoors in the spring. After my father died last year, I took up the care of the plant. Not having a sunny basement window, or warm-enough garage, I keep the geranium in a sunny family room window where it thrives all winter. It begame a little leggy this summer – this fall I will be diligent with pruning & pinching. I have grown 5 young geraniums from this plant by placing a 5″ branch in water in a windowsill. It takes weeks but once the roots mature, I plant in a pot for other members of my family. It’s a very sentimental effort, but very rewarding.

    I held my geraniams over for the winter, and when I took the plant out of the pot, it had tons of tiny white spots on the outside of the dirt ball. What caused this, and should I throw the plant out? Thanks you, Nancy

    I received a large geranium plant this summer. I have never seen one grow so large, all in all I had 49 flowers on it they just keep growing, and still is. I just cut it back about 4 inches for the winter. I thought I would store it in my basement. so can I still keep it growing all winter, or should I let it rest. there are still blooms on it, and many buds yet to come. thank you in advance for any info.

    I have had good luck cutting my geraniams back, storing them in a cool garage cover erred with a paper bag. No watering all winter. They have done well. Is that just luck or a valid way to go?

    Last year I got several geraniums for outside for my birthday in April. Over the winter I kept some…the ones I could carry and a few on the front porch. The only advice I got was not to water them. Well all of them look dead,dead, dead!

    I live in Oregon and this was a cold winter ( live on the coast) I’m not a gardener, in fact when a new plant I look at it and say…”welcome, you have come here to die!!!

    I kept my large plant indoors during the winter. It has some longer limbs and is not a good shape. I want to remove some of the nice ones about a foot long on sides etc. but want to know if I should put in water to root first or can I just plant in pots and they will root that way. I have some I had in the garage in pots during the winter that just needed watered and fed and are in good shape. I am an amateur gardener. Thanks.

    I want to plant geraniums outside. I live in Sacramento, CA and it is almost September. Will they make it thru the winter season? It usually doesnt freeze around here…

    Gerri, the garage might work, depending on how warm it is, or you can bring them into the house. But you can definitely store geraniums in pots over the winter – see instructions above.

    I live in Zone 5 in OHio – I have been told, I can bring my potted geraniums into the garage and they will survive winter. Just cut them back in spring and bring them out again and they will survive. I haven’t been able to find any info on line about doing this. Please advise! Thank you

    I was wondering, do I need to bring my big containers in
    for the winter? They are filled with dirt and I wondered
    if the freeze would ruin them. I live in Ohio and we usually get very cold weather each winter.
    I appreciate finding out how to store them.
