Geranium pruning can be done in three different ways. Depending on what you want to do, you can choose either one.
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.
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!
How can I spring-prune my geraniums that are getting too lanky?
To let you see what I was removing from the stems, I brought a sample of them out onto the patio.
4. Keep trimming stems to establish the framework for the plant’s growth.
5. While pruning, don’t forget to take a step back and survey the plant. Any stems you don’t like should be cut off (I always end up cutting off a few more after I think I’m finished!). & prune any tips that are needed.
Should leggy geranium plants be pruned?
Not sure what to do with geraniums that are too leggy? Aim to prune. You should prune your spindly geraniums by approximately a third before bringing them inside (often in late November). Make sure to get rid of any stems that are sick or dead as well. Geraniums that are too lanky can be pruned to keep them from overgrowing and looking unattractive.
Another method for tying up lanky plants is pinching. This is typically done to mature plants to encourage bushier growth. Once new growth has reached a couple inches (8 cm) high, pinch out around 1/2 to 1 inch (1-2.5 cm) from the tips. This can be done during active growth or soon after trimming.
How much should geraniums be reduced?
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.
Do I need to remove the dead geranium flowers?
Of course, removing all the dead blooms will immediately improve the appearance of your plants, but there are additional benefits to understanding how to deadhead geraniums.
Your geranium will focus all of its energy on producing seeds if you leave the dead flowers on it rather than producing new blooms. By cutting them off, the plant may focus its efforts on developing new blossoms. Therefore, if you keep up with the deadheading, you’ll have enough of new flowers all summer long for your hanging basket ideas or other displays.
Additionally, keeping them organized in this way enhances the air flow around the plant. This lessens the risk of the widespread fungus illness botrytis blight.
Prune Heavy Once per Year
Hardy geraniums enter a dormant state over the winter every year. Most people can endure colder temperatures. Most of them won’t die, but they don’t grow.
That depends on the local climate. Cut back the geraniums to three to four inches in the fall if the weather is consistently below zero, and then overwinter the plant indoors.
Geraniums may often survive the winter outdoors in mild winters with just a nice, thick covering of mulch.
Spring Prune to Prepare for Blooms
The spring cutback is the first reduction of the year. Check the plant at this point for brown or fading leaves. Since they offer no benefit to the plant, they are the first to perish.
Examine the stems for rigidity. Cut off any stems that feel spongy. When gently squeezed, healthy stems should feel solid.
Summer Prune for More Vibrant Blooms
Deadheading season is during the summer. removing the stems that the flower buds were attached to in order to remove spent and fading flowers.
Geraniums should ideally be clipped three times a year, not including routine deadheading of the season’s wasted flowers. The best seasons to prune geraniums for shape and to promote bushy growth are spring or fall.
Because they are promoted as being simple to grow, geraniums are quite popular. They are that. They are not shrubs, though. They are shrubs that develop tall, slender stems on their own.
Geraniums must be regularly pruned to maintain their shape; otherwise, they will continue to grow straight up.
Why are my geraniums looking unkempt?
Before storing geraniums indoors for the winter on a shelf in the sun, severely prune them back to 6 inches tall. Cut the green branches back to the mature, tan wood when trimming geraniums at the end of the season to encourage additional branching. Pinch branches to keep them short and branching once they start to grow in February. In U.S. Department of Agriculture plant hardiness zones 10 through 11, geraniums can be grown outdoors year-round.
Tip
Geraniums should not be planted in spring until the soil temperature reaches 50 to 60 degrees Fahrenheit and two weeks before you usually switch on the heat in the fall. Extreme temperatures cause plants to grow slowly and become frail. To prevent spreading fungus or germs picked up in the garden when cutting back plants in the fall, clean hand pruners with rubbing alcohol or a 10% solution of household bleach and water after each plant.
Why are the leaves on my geraniums 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.
Can I store my geraniums for the following season?
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 geraniums be used for after flowering?
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. Then, in the fall or spring, these are again pruned.
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.
