Geraniums can be kept at their best through pruning. Geraniums should be pruned to avoid becoming woody and leggy, especially if they have spent the winter dormant. You may learn how to prune geranium plants to keep them looking well in the information provided below.
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.

When and how should I prune geraniums?
Geraniums and pelargoniums are undoubtedly resilient and simple to grow, however they cannot be considered “no maintenance plants.” Giving them a hard prune at the end of the summer, when the flowering is winding down, is an excellent idea to prevent them from getting too leggy. In March or April, Jane advises cutting back geraniums and pelargoniums by a third to a half. The plants will grow quickly in the spring, bush out attractively, and produce a magnificent flush of blooms.
Don’t discard pruning cuttings; they make excellent propagation materials. Trim them to a length of 10 cm, remove all but a few of the lowest leaves, and set them aside so the ends can dry out. The cuttings may be potted up after a couple of days, and you’ll have some lovely new plants for your space come spring!
Pruning Geraniums After Winter Dormancy
The optimum time to prune geraniums is in the early spring if you put them into dormancy for the winter or if you live in a region where they lose some of their leaves over the winter.
Take off all of the geranium’s brown and dead leaves. After that, remove any diseased stems. Squeezing a healthy geranium stem will feel firm. Cut down the geranium plant by one-third, paying particular attention to stems that have begun to turn woody if you want a less woody and lanky plant.
Cutting Back Geraniums That are Wintered Alive
The best time to prune geraniums is in late fall or right before you bring them inside, if you intend to bring them indoors. If you do not put your geraniums into dormancy for the winter and they remain green in the ground or in containers year round.
Trim the geranium plant back by one-third to one-half, paying special attention to lanky or woody stems.
How to Pinch Geraniums
In order to make the plant grow more bushy and compact, geraniums are sometimes pruned. You can pinch either newly purchased bedding geranium plants or geraniums that have been overwintered. Pinching of geraniums begins in the spring.
When a stem on a geranium plant reaches a few inches (7.5–10 cm), cut off 1/4–1/2 inch (0.5–1.5 cm) of the stem with a sharp pair of scissors, or even with your fingers. Repeat over all stems. The geranium will be forced to produce two new stems off of the original stem as a result, which will result in a bushier, fuller plant. If you prefer, you can keep pinching geraniums all throughout spring.
Geranium pruning is simple and improves the appearance of your plant. You may enjoy your geraniums more now that you know how to prune geranium plants.
Do I need to remove the dead geranium flowers?
Without deadheading, the blooms will soon stop blooming and have a propensity to grow sparse. Additionally, this method stops the plant from producing new seeds. When your geranium blooms start to look weak or brown, you should deadhead them.
If you want to deadhead your geraniums, you need to go a bit further into the plant and snap the stem below the node or junction, where new growth starts. You have the option of using shears or only your hands. Healthy, well-watered plants have stems that are simpler to snap.
Deadheading will foster the growth of fresh, full blooms in place of any that appear weak or less full. Work your way through your plant, doing this in all of its parts. Within a few days, new, fresh blossoms will start to appear. The entire procedure just takes a few minutes, but it can extend the life of your plants by many weeks or even months. You can either pick a few stems each day while taking care of your plants, or you can do this every couple of weeks if you have the time.
Where do you cut geraniums off?
A delicate perennial, geraniums are frequently planted outside as annual flowers. There are numerous variations that are offered in a variety of hues. Geraniums thrive and bloom in partial shadow, which makes them a great addition to gardens with little light, in contrast to many other flowering plants. When planted in containers that are carried indoors during the winter, geraniums also flourish all year round. Whether the geranium is placed in a bed or a pot, pinching back the plant promotes full, bushy growth and further blooming.
In the spring, prune back overwintered plants before they resume active growth. Trim all foliage and stems that are dead or damaged, but only by around two-thirds of their previous height. For pruning, use well-kept, razor-sharp scissors.

- Geraniums thrive and bloom in partial shadow, which makes them a great addition to gardens with little light, in contrast to many other flowering plants.
Once the plant is actively growing once more or after relocating fresh plants to a permanent bed or pot, pinch off the top 1/2 inch of each stem. This promotes further branching and results in a fuller plant.
When the blossoms start to wilt, pinch them off. Pinch off the top of each blossom stem just above the nearby leaf cluster. As a result, no seeds are produced, and more buds are set.
Geraniums should be revived in the middle of the summer if they start to seem lanky or worn out. In order to give the plant a rounded appearance, pinch off the top 3 to 5 inches of each stem. Each stem should have a leaf or leaf node directly above it. The geraniums will immediately become bushier and start blooming once more.
- Once the plant is actively growing once more or after relocating fresh plants to a permanent bed or pot, pinch off the top 1/2 inch of each stem.
Even while pinching with your fingers works well for most trimming, shears can be used if the entire plant needs to be rejuvenated.
After significant cutting, fertilize the plants. This promotes the plant’s rapid growth of foliage.
Following pinching, plants may stop blooming for one to three weeks. If you keep giving them regular water, they will soon start blooming again.
How can I encourage my geraniums to bloom more?
How to Increase Hardy Geranium Blooms
- Give the Right Lighting. Make sure your blooms are receiving enough sunlight.
- Maintain Soil Moistness. Keep the soil damp but not soggy.
- Detach any leggy growth. Midsummer is the time to prune the plants.
- Give Your Plants Food. To promote blooming, apply a fertilizer strong in potash.
Why are my geraniums’ leaves going yellow?
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 are geraniums prepared for winter storage?
Your geraniums should be potted six to eight weeks before the final average frost date in your region. Clean up the plants by removing any extra-long roots and trimming the stems back to healthy green growth, as shown in the inset. Take the geraniums out of the bag or box they have been sitting in for the past several months. By the time it was cleaned up, this one was only a little over 4 inches long.
Then, put potting soil in a container that has already been wet, and tuck the stem down so that two leaf nodes are below the soil—this is where new roots will grow.
How are geraniums cared for outside?
Geranium plants have a variety of requirements that will vary depending on where and how they are grown. Geraniums will withstand moderate light levels but require lots of light to bloom indoors. They also require indoor temperatures of roughly 65–70°F (18–21°C) during the day and 55°F (13°C) at night.
Additionally, these plants need to be planted in potting soil that drains properly. Geraniums need a soil mix with equal parts soil, peat, and perlite when grown outdoors. The soil should be wet and well-draining.
Place your geraniums in a location that receives six to eight hours of direct sunlight per day. Wait to plant these plants until the risk of frost has passed because they need to be shielded from the cold.
Plants should be placed 8 to 12 inches (20–30 cm) apart and at roughly the same depth as the pots they were originally planted in. To help plants retain moisture, mulching is also advised.
Do geraniums survive the cold outside?
- Make sure you thoroughly inspect your geranium plants before bringing them inside for the winter. Look for symptoms of pests and illnesses like rust and remove any dead leaves or wilting blossoms. Only zonal pelargoniums are impacted by this, but it is becoming more widespread. It arrived in the nation for the first time in 1968, and it does best in the moist summer or fall months. Fortunately, it doesn’t seem to spread to the plants quickly and is simple to treat, so merely plucking the afflicted leaves is an effective management. You might also consider using the fungicide Dithane 945 as a spray.
- Placing your overwintering plants somewhere bright and sunny will help them retain their need for light throughout the winter. Your plants will receive 50% less light if they are placed more than three feet from a window!
- Because your plants continue to thrive throughout the winter, keep the roots moist. While geraniums frequently survive droughts, they rarely flourish. Show plant growers take special care to keep the roots of their plants damp but never soggy during the winter.
- Ventilate as frequently as you can to maintain a dry environment surrounding your plants. Your plants will turn into a moldy, rotting heap if you don’t allow the air to circulate. The greatest electric fan heaters are those that operate automatically since they circulate air while simultaneously raising air temperature.
- Geraniums are fairly inexpensive to overwinter in the greenhouse because they only need to be kept frost-free. To keep temperatures above freezing, however, we do advise utilizing a heater. Set the thermostat on your heater to 5C, which is 41F. The plant will not survive if the stems become frosty! The winter months are a great time to store your delicate pelargoniums in porches, sunrooms, or conservatories.
