If given the right conditions, geraniums may survive the winter indoors. They require cool conditions, ideally in the low 60s (F). The majority of basements provide excellent winter home for geraniums. To give your plants ample light, simply add a fluorescent light fixture or a plant light.
Can geraniums survive the cold indoors?
Pelargonium species, which come in pots, make great indoor plants that may be grown all year round. They normally become available in March through June, and if given enough light inside the house, they will bloom continuously. There are several fresh varieties, like vining and hanging basket cultivars. They are available in many different types of containers and at varying stages of development.
How are geraniums maintained indoors during the winter?
Geraniums are incredibly simple to store for the winter—just place them in a cardboard box or a paper bag and secure the top. The following advice will help them survive:
- Maintain geraniums in a cool, dry area with a temperature of 50 to 60 degrees F.
- Once a month or so, remove dried leaves from the bag or box and check for mould.
- Check the stems quickly at the same time; they should be stiff. Throw away any dried-out, shrivelled stems you uncover.
- If you see that the plants are becoming really dry and crispy, give them a brief soak in water.
- Plants with stems that appear to be blackened or mildewed should be disposed away.
Geraniums are typically kept in a sack upside down. Although the exact cause is unknown, one idea holds that it does so by pushing moisture into the stems. Whatever the cause, storing them in this manner is neither harmful nor necessarily harmful.
Can geraniums survive the cold in pots?
Geraniums can be overwintered inside in three different ways: as a houseplant, as a dormant bare root, or as cuttings. Your decision will be influenced by the amount of room you have indoors and the range of temperatures you can tolerate. Here is a closer examination of each method.
Overwintering geraniums as houseplants
If you want to keep the entire potted plant and have lots of room close to a window that gets bright, direct light, go with this option. A draughty west-facing window would be the ideal place for your potted geranium to spend the winter because geraniums prefer it chilly (55 to 65 F is optimum).
Wash the foliage well with your hose and repot the plant in new potting soil to prevent bringing unwanted pests from outside. You might also use insecticidal soap, which is sold in most garden centres and hardware stores as well as online. Avoid taking the plant indoors if it shows any signs of pests or illness. Only strong plants have a chance of successfully overwintering indoors.
During the winter, keep the soil wet but not damp. No more humidity is required. If the stems begin to sag, pinch them back to keep the plant compact throughout the winter. When springtime comes around, you may start fertilising once more and transfer the plant back outside as soon as the temperature reliably rises above 50 F.
Overwintering geraniums as dormant bare root plants
This is the most typical way to overwinter geraniums, but it won’t work unless you have a dark, dry place that stays around 50 degrees throughout the winter.
First, dig up your geranium before it freezes and shake the dirt off the roots. To stop mould from forming, let the plant sit and dry for a few days before storage. Before moving onto the following phase, the roots must be completely dry.
The roots should be kept in a dark, dry place that doesn’t get colder than 45 degrees throughout the winter. Geranium roots should be kept at a temperature of 50 F. You can keep them by doing:
- It has been customary for generations to hang the plants upside-down from the rafters;
- placing them on a shelf after wrapping them in newspaper or a paper bag;
- they were put in a cardboard box.
Step 3: Every month or so, look for mould, black leaves, or limp stems at the roots. Remove any plant or root components that are harmful. Most of the stems should endure the winter in good shape. Before re-storing them if they become too wilted, give them a good bath in water and let them air dry.
Step 4: Reviving your geraniums involves cleaning them up, pruning the stems back to healthy green growth, and replanting them in new potting soil about six weeks before your final frost date. Where the new roots will grow, bury the stems two nodes deep. When you notice fresh growth in one to two weeks, keep the plants somewhat dry; after that, keep the soil moist until the plants are big enough to replant outside.
Overwintering geraniums as cuttings
If your light windowsill area is limited or you are concerned that bringing in your entire potted plant would also attract unwanted bugs, this is a nice technique to try. Additionally, it’s a fantastic way to multiply your existing geraniums.
To trim plants, you’ll need:
- a cutting edge.
- Most hardware stores and garden centres sell rooting hormone, which is sold online.
- Use little terracotta or plastic pots, or recycle a clear takeaway container for roasted chicken.
- If you don’t eat chicken, use clear plastic bags to cover the pans.
How are geraniums maintained indoors?
Once the roots have established, new top growth appears. Rooting might take one to four weeks, depending on the type of plant, light, and temperature. To keep the pots from drying out if you set them in a south window with direct sunlight, you might wish to loosely cover them in a clear plastic bag. Yellowing leaves typically result from overwatering or too cold of a climate.
The plants in their original containers or the ones you brought inside from your outside beds will be substantially smaller once you have taken cuttings from them. Take out any dead branches, brown or yellow leaves, flowers, or flower buds. Place them in a warm, well-lit area with modest water. You might want to take another round of cuttings in late winter or early spring depending on your needs and those of your friends.
For them to grow and bloom indoors, they require at least four hours of daily direct sunlight at regular room temperature. While they are actively growing, water them sparingly, making sure the potting mix is moist but never waterlogged. Between waterings, let the top half inch of the soil dry out. When there are signs of growth, apply a diluted 20-20-20 soluble fertiliser every three to four weeks.
For many years, I’ve kept ‘Shone Helena,’ a magnificent salmon-pink geranium, in my sunroom, where it blooms for most of the winter.
How long do indoor geraniums survive?
One of the most dependable types of garden flowers is the geranium (Pelargonium spp.). Around the world, they are grown as indoor plants, as garden annuals in USDA plant hardiness zones 2 through 8, and as perennials in zones 9 through 11. If given the right care, a common geranium can live for 40 years or longer. The most frequent causes of geranium death are overwatering or underwatering, insects or illness, and cold snaps. They might eventually grow long and unsightly, at which point they should either be replaced or removed.
How long do geraniums in pots last?
My geraniums are no longer blooming. I fed them, but it was ineffective. What’s the issue?
You might be feeding them too much. Pelargoniums, a genus of geraniums native to the Mediterranean, flourish in full sunlight and relatively infertile soil. Overfeeding can be the issue if you have a lot of foliage growth and the plants appear healthy. For a while, stop giving them food. But if your plants are becoming older and their stems are getting lanky, it might be time to propagate. Although they can live much longer, geraniums typically only bloom for two years on average before becoming woody and losing their blooming ability. Thankfully, geranium propagation is simple. Simply cut stem tips with at least two pairs of healthy leaves from a four-inch stem. Cut the stem at the lowest point, dunk it in hormone rooting powder, and then plant it in a mixture of half sand and half peat moss. In around three weeks, repot in ordinary soil after providing adequate watering and covering with plastic to assist preserve moisture. Sticking the cutting in water and letting it grow roots before potting is a simpler method.
Can I store my geraniums for the following season?
Pelargoniums from your garden can be overwintered in a number of methods. You may preserve these delicate perennials over the winter by placing them in some newspaper, a cardboard box, a paper bag, or a sunny windowsill, and they will blossom again the following spring and summer. I’ll go over your options and offer some advice for winter maintenance.

What should you do with geraniums that overwintered in the spring?
Iowa’s AMES
Beautiful plants like geraniums offer colour and life to any landscape. They are not prepared to endure the hard winter weather, though. Geraniums can be brought indoors to overwinter and then replanted in the spring.
Horticulturists at ISU Extension and Outreach can assist with your inquiries regarding overwintering geraniums and how to keep them healthy during winter weather.
How can I overwinter geraniums indoors?
By obtaining cuttings, potting up individual plants, or preserving bare-root plants in a cool, dry place, geraniums can be overwintered indoors. Before the first fall frost, remove plants from the garden (or take cuttings).
How do you take geranium cuttings?
Take three- to four-inch stem cuttings from the terminal ends of the shoots using a sharp knife. Pinch the bottom leaves off each cutting before dipping the base in a rooting hormone. Insert the cuttings into vermiculite or a mix of perlite and sphagnum peat moss as a rooting media. Rooting containers that have drainage holes on the bottom are pots and flats. Just enough to allow the cuttings to support themselves should be inserted into the media. Water the rooting media once all of the cuttings have been placed.
Place a clear plastic bag or dome over the cuttings to stop the plant foliage from wilting after allowing the medium to drain for a few minutes. The cuttings should then be placed under bright light—not direct sunshine. In six to eight weeks, the cuttings should begin to root. Remove the cuttings from the rooting media after they have healthy root systems and plant each rooted cutting in a separate pot. Until spring, keep the potted plants in a window with natural light or under artificial lighting.
How do you overwinter geraniums as potted plants?
Each plant should be dug up carefully and put in a big pot. After giving each plant plenty of water, set the geraniums in a window with natural or artificial light. Geraniums prefer a cool environment indoors. The ideal temperature range is between 60 and 65 degrees Fahrenheit during the day and a little bit lower at night. Plants need watering around every two weeks. By the end of winter, geraniums are likely to grow tall and lanky. Trim the plants back in March. Reduce the geraniums by a third to a half. Within a few days, the geraniums will start to grow once more, and by May, they should be beautiful specimens.
How do you overwinter geraniums as bare-root plants?
The geraniums should be carefully dug out before the first fall frost. Remove the plant’s roots’ soil by shaking them. After that, put one or two plants in a sizable paper bag and keep it dry and cool (45 to 50 degrees Fahrenheit). It might be appropriate to use an indoor porch or an unheated bedroom. Hanging the plants upside-down in a cool, dry area is an another (somewhat messier) option. Eventually, the leaves and the shoot tips will wither away.
Trim or prune each plant in March. Get rid of all the dried-out, lifeless stuff. Return to firm, green, living stem tissue through pruning. After pruning, pot the plants and give them plenty of water. Put the potted geraniums in a window with natural light or next to a light source. March pruning and potting of geraniums should result in lovely plants that may be put outside in May.
In the winter, should geraniums be pruned back?
You should prune a perennial geranium after it has bloomed all season and starts to wither. This helps the plant store energy for the spring while simultaneously keeping it dormant for the winter. This could need to happen any time between August and late October, depending on your zone. Cut perennial geraniums down to 2 or 3 inches above the soil with a pair of trustworthy shears, ideally at nodes or new growth points. Take out any more flowers or foliage. You’ll have a collection of thick stems that is really ugly. But don’t panic, your blooms will return in full bloom the following spring.
How frequently should indoor geraniums be watered?
Geraniums don’t need daily watering unless the soil where they are planted is evaporating that quickly. When the soil is left to dry out between waterings, geraniums flourish at their best. Overwatering can happen if the soil is kept damp at all times. If you don’t allow the soil dry completely, it can be challenging to determine when it’s time to add extra water.
- Typically, geraniums don’t need daily watering.
- Between waterings, let your geraniums’ soil dry out.
- Delay watering your geraniums if the soil is still wet from a recent downpour or precious watering.
- The soil may dry out in a day of intense heat. In this situation, daily geranium watering is OK.
Ensure that geraniums in pots or other bigger containers are properly drying out in between waterings. If the soil is still wet from the last watering, avoid watering. Several geranium diseases can be brought on by not allowing the soil to dry out between waterings.
Location
Geraniums enjoy the sun and don’t mind being drenched in it over extended periods of time. Put them there if your room has a window that faces south or west. Geraniums need exposure to direct sunlight to develop and bloom, even when cultivated indoors.
Soil
Remember that the correct soil is essential! Be careful not to fill the drainage holes with earth. Use potting soilless. Use soil that is loamy and well-drained instead of garden dirt.
Watering
The most crucial step is now, and it determines whether your geranium plant will live or die. Geranium doesn’t need routine watering because it is a drought-tolerant plant. Only water the soil when it feels dry. Do not overwater!
Temperature
Don’t put your geranium plants in places that are too hot, too cold, or draughty. If a room is warm, geranium adapts to it effectively. But the ideal temperatures are between 65 and 70 degrees Fahrenheit during the day and 55 degrees Fahrenheit at night.
