Geraniums need to be gradually returned to the warm, bright growing conditions in which they thrive after a long winter of low light and chilly temperatures. Moving the pot to the hottest, brightest location indoors in the early spring is the first step in reviving dormant geraniums. The optimal window for breaking the plant’s dormancy is one that faces south or west and is not shaded, but any window that gets 10 to 12 hours of light per day will do. Fill the pot with water until a small amount of it drips into the catch basin. Use sharp pruning shears that have been cleaned with rubbing alcohol to remove any dead leaves or stems.
As soon as the first new leaves show at the tips of the stems, fertilizer should be applied. A balanced 15-15-15 fertilizer or a fertilizer designed for blooming, such as 7-9-5, is advised for feeding, according to Logee’s Plants. Mix one gallon of water and one half teaspoon of fertilizer together. Once nighttime temperatures remain between 55 and 60 degrees Fahrenheit, move the geranium to a warm, sunny, and protected area outside. Grow it in a pot or in the garden, in bright circumstances with midday shade.
What can I do to revive my geraniums?
Geraniums can live for the majority of the winter without soil, which sets them apart from most annual flowers. Due to their thick, succulent-like stems, geraniums may withstand prolonged periods of dryness if they are handled correctly to prevent illness.
How to Store Geraniums
- Before the first harsh cold of the season, remove the plant from its outdoor container and gently shake the soil from the roots.
- Reduce the plant by roughly 50%, taking care to remove any unhealthy-looking growths, flowers, or dead leaves.
- For the winter, pick a cool, dark spot, such as an unheated basement, garage, or shed. It is crucial that the temperature stay above 45 degrees F.
- The plant should be hung or put in paper bags. If you decide on using bags, don’t close them too tightly; you want some air to flow through them. When geraniums are overwintered, mold can grow on them. When hanging plants, The Spruce advises leaving enough space between them so that air can flow around them.
- Put tags (loosely) around the roots of your plants to identify them by color, or group them according to color while storing them.
Care for the Dormant Geraniums
- Take the plants out of the bags and give the roots a 1- to 2-hour soak in warm water. I’ve seen some professionals advise doing this once a month, while others advise doing it a few times during the winter. Before putting the plant back in the paper bag, give it time to completely dry. THIS IS ESSENTIAL.
- Even if the leaves are withering, check the geranium stems every two weeks to make sure they remain firm. You should discard any plants with withered stems right away. Anything with mold on it should be thrown away.
Reviving After Dormancy
- Trim any dead stem tips, and get rid of any roots that are too lengthy.
- Before potting, bare root plants can be given an extended soak in water to rehydrate the roots.
- Six weeks before the last frost, plant geraniums.
- When planting, bury the plant two leaf nodes deep in moist potting soil to encourage root development.
- Give them plenty of water.
- To reintroduce light and encourage fresh growth, place the newly planted geraniums in a sunny window. After inactive storage, it will probably take the plants 2-4 weeks before they begin to grow.
Do geraniums regrow in the spring?
Amazingly, annual geraniums (Pelargonium hybrids) thrive and flower wonderfully from spring till frost with little effort. The next spring, these resilient tiny plants will take off and grow once more if you dig them out in the fall and store them in a cardboard box or paper bag for the winter. Learn how to preserve your geraniums over the winter so you can enjoy them year after year by watching our video and reading the article below.
What should you do with geraniums that overwintered in the spring?
Iowa’s AMES
Beautiful plants like geraniums offer color 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 a 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.
Hardy Geraniums vs. Pelargoniums
Pelargoniums should not be confused with hardy geraniums. You might be wondering what makes a geranium different from a pelargonium. Similar to some siblings, they are both members of the same plant family, but they could not be more unlike.
Pelargoniums cannot withstand frost, while hardy geraniums can. Pelargoniums are usually treated as annuals and replanted each year, but true hardy geraniums are perennials that grow back every year. Pelargoniums die in the winter.
Prune your Hardy Geraniums
Your sturdy geraniums will look their best and promote new growth if you prune them properly. By correctly pruning your hardy geraniums after the blooming season, you can encourage repeat blooming. The majority of geraniums can be cut back twice in a single season, which allows them to bloom at least three times.
When to Prune
Your hardy geraniums should be pruned in accordance with the season you are in. Rozanne will require various cuts in the spring, summer, and fall. To maintain your blooms rich and healthy, mark your calendar and adhere to our seasonal trimming recommendations.
What tools you need
Your geraniums may be pruned fairly easily. All you’ll need is the ability to prune, a pair of sharp pruners, your favorite mulch, and your favorite gardening gloves. Watch this video to learn more about pruning strategies in detail.
How to prune
You shouldn’t be concerned that pruning your flower’s back will harm her. The majority of hardy geraniums require trimming to promote new growth and prevent them from encroaching upon other plants.
Trim the plant back to within a few inches of the ground or to about an inch above the main stem once the flowering is completed or you find old growth. Remove any brown stems or yellow leaves after that by going inside.
Soon after trimming, more leaves will start to appear. Some resilient geraniums even have the ability to blossom again. Maintaining correct pruning on your plants encourages new development and keeps them from spilling out throughout your landscape.

What appearance do overwatered geraniums have?
Having too much moisture or overwatering is one of the most frequent reasons of yellowing leaves. Geraniums typically have yellow leaves at the bottom when they are overwatered. They could also get water patches that appear pale. If so, you should cease watering right away so that the plants can dry off. Remember that geraniums do not like excessive amounts of water and are drought-tolerant plants.
Geranium yellow leaves can also occur when the water or air are too cold. Since geraniums prefer warm climates, they struggle in cool climates. Geraniums with yellow leaves can be caused by prolonged cold weather, particularly cold, wet weather, or by cold snaps in the spring.
Additionally, a nutrient deficit could be the reason why the geranium leaves turn more yellow than green. Every third watering or once a month, geranium plants should be treated with a comprehensive, water-soluble fertilizer (ideally one with micronutrients). Geraniums’ yellow leaves can be avoided using fertilizer, and the plant will grow larger and produce more blooms as a result.
A geranium with yellow leaves sporadically indicates the presence of a disease. Verticillium, for instance, is a fungus that can result in stunted growth, withering, and brilliant yellow leaves.
What about the yellow-edged geranium leaves? Dehydration or a lack of water are frequently blamed for geranium leaves that have yellow margins or yellow tips. Geraniums require some water even though they can withstand drought. In these situations, you can use your fingers to feel the soil to gauge how dry the plants may be and water accordingly. Trimming the yellowing growth off might also be beneficial.
You can see that geraniums with yellow leaves often only require a little tender loving care in order to recover. If you provide a geranium with what it need, the leaves won’t turn yellow.
How can I tell if my geraniums are still alive?
How may a plant be identified as dead? Although it can seem like an easy question to answer, it can occasionally be challenging to determine whether a plant is indeed dead. Plants lack vital indicators like a heartbeat or breathing in and out, which would make it simple to determine if they are actually alive or dead. You must instead rely on more nuanced cues.
Do not become alarmed if your plant has lost all of its leaves or if they have all turned brown. The quickest approach to determine whether a plant is dead if you think it could be but aren’t sure is to look at the stems. The plant’s stems should be flexible and firm, and if they are still alive, they will have a green tint on the inside.
Check the roots for the same issues if the stem is soft or brittle. The roots should be flexible but solid as well. The plant is dead and you’ll only need to start over if the stems and roots are brittle or mushy.
When should I trim my geraniums back?
reducing after blossoming After flowering, early-flowering perennials like geraniums and delphiniums are pruned to almost ground level to promote new growth and late-summer blooming. These are then cut back again in autumn or spring.
How are geraniums prepared for spring?
One of the most popular plants for containers and gardens is the geranium. Their vibrant hues and strong, well-shaped foliage are unmatched. Geraniums typically come in larger sizes in the garden center, which raises their price compared to other summer annuals.
Geraniums may be easily kept over the winter and enjoyed again the following year, unlike many of their competitors. Here’s how to overwinter your magnificent geraniums indoors if you don’t want to see them killed by frost this fall.
Methods of Overwintering Geraniums
Geraniums can be preserved in three different ways to endure the winter:
- inside in pots during the winter.
- Keep the naked, dormant roots.
- To create new plants, propagate cuttings.
Fall:
- Carefully dig out your geraniums before the first frost and pot them in 6- to 8-inch-diameter containers with lightweight potting soil. You can skip a step if yours are already in containers! Any that appear sick or diseased should be discarded.
- Reduce each plant by a third to a half. The cuttings should be saved and rooted to produce new geraniums.
- Give the pots plenty of water.
- Put the pots in a cool, well-lit area. Temperatures around 60 F in a sunny window are ideal for geranium overwintering. They struggle in dimly lit or hot environments.
Spring:
- Give your geraniums a mid-spring fertilization.
- When the threat of frost has gone, put them back outside. You have the option of leaving them in their containers or replanting them in your flowerbeds.
Overwintering Bare-Root Geraniums
Geraniums may endure winter dormancy if maintained above freezing since they have great thick roots and stems. Geraniums can also be stored as bare roots after going dormant. Take these actions:
- Carefully pull out your geraniums and shake all the soil off the roots before the first frost.
- To keep them, place them in unsealed paper bags or hang them upside-down in a cool, dry area at roughly 50 degrees Fahrenheit (a garage is perfect).
- Pull out your geraniums every a month or so and give the roots an hour or so in water to soak.
- Then let them dry completely before re-storing.
- The stems should remain solid, but the leaves will eventually all fall off. The plant is probably doomed if the stems start to shrivel as well!
- Check your geraniums in the early spring.
- Eliminate any shriveled areas.
- Lightly prune them, removing any dead tips.
- Put the roots in water that has some plant food mixed in for a few hours.
- Place the roots in potting soil and give them plenty of water.
- Put your potted geraniums in a window that gets plenty of sun or beneath a grow light. It can take them a few weeks to awaken and begin to grow!
- You can bring them outside once all threat of frost has passed.
Propagating Geraniums From Cuttings
The final alternative is to let go of your original geraniums and take care of fresh ones that were propagated from cuttings. This is how:
- Cut off sections of the branches that are three to four inches long with a sharp knife or pair of shears. Instead of a side branch, the terminal end of the stem—the very tip end—produces the best cuttings.
- Remove any flower buds, and pinch off the leaves in the bottom third of the cutting.
- After removing the leaves, sprinkle the wounds where the cuttings were made with rooting hormone by dipping the bottom of each cutting in it.
- Each cutting should be planted with peat moss, sand, or perlite in the bottom third. You can grow them in trays or in individual pots (plastic planting trays are available with a clear cover to hold in moisture).
- Set the pots on a drainage tray and give them a thorough watering, ideally starting at the bottom (fill the tray with water and allow it to soak to keep from washing away the rooting hormone).
- Use the tray’s included cover or cover your pots with clear plastic.
- Place away from the sun in a sunny window. Although they require light, your clippings cannot withstand direct sunlight.
- By wetting the drainage tray, removing the plastic cover, or sprinkling the plants and soil with a fine mist, you may maintain the moisture level of the planting medium.
- In 6 to 8 weeks, your cuttings should begin to root. You can transfer them to their own pots with standard potting soil before the beginning of the next spring.
- Your new plants will branch out if you fertilize them and prune the new stems.
