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.
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.
How can leggy geraniums be reduced?
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.
How far back should geraniums be clipped for the winter?
Over the winter, I keep my geraniums in the same pot. What time of year is ideal for pruning them back? Will they be ready to bloom when I transfer them outside if I do?
Geraniums should be prepared for the forthcoming season by mid-March. Geraniums stored for the winter in a cool, dark spot should be potted up and pruned back. Start watering the plants after relocating them to a window with natural or artificial light. Once the plants begin to grow, you can fertilise them using any fertiliser designed for flowering houseplants. A spring trim will also be beneficial for geraniums grown as indoor plants. Plants should be pruned back to 4-6 inches to promote thicker, more compact growth. As soon as the plants start growing again, fertilise them. By the start of the growing season, your plants will be fully grown and prepared to blossom.
How are geraniums prepared for 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.
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 organised in this way enhances the air flow around the plant. This lessens the risk of the widespread fungus illness botrytis blight.
When should plants be pruned back during the winter?
When in the fall is the greatest time to cut back? A: “Before the fresh new growth starts and when they start to look too ratty for you,” according to Sarah. Wait until after the plants have had multiple hard frosts to prune frost-sensitive plants to be sure they are dormant.
How are potted geraniums pruned?
Geraniums, a delicate perennial plant, offer colour to beds, borders, and containers. They need to be taken indoors to overwinter since they are fragile and struggle to live in frigid temperatures. Geraniums should be thoroughly pruned back to guarantee abundant and healthy blooming the following spring, regardless of whether you currently have them growing in containers or are potting up the outdoor plants for winter. Geraniums can also be revived by pruning in the middle of the summer when they start to grow lanky and seem ragged and worn.
After the first fall frost, trim geranium to 1/3 of their previous height with clean, sharp scissors. To prevent the plant material from becoming a breeding ground for pests or disease, remove and discard all of the clipped plant material from the container.
After pruning, properly water the plant. Until the plant starts actively growing again in the spring, place it in a bright window or under grow lights.

- After the first fall frost, trim geranium to 1/3 of their previous height with clean, sharp scissors.
Once the plant starts actively developing, pinch off the tip of each stem to promote branching and prevent legginess. Trim the top 1/4 to 1/2 inch with a pin.
Throughout the summer, remove the dead blooms to promote new flowering. Once they start to fade 1/4 inch beneath the bloom head, snip or pinch them off.
If the plant starts to look poor or the blooming stops, cut it back completely in the summer. Reduce it to half to three-quarters of its previous height, then take the plant material out of the pot as usual. After pruning, water thoroughly.

- Once they start to fade 1/4 inch beneath the bloom head, snip or pinch them off.
The geranium recovers to fullness and blooming after summer pruning in a week to ten days.
Large containers should be placed on wheeled carts so they may be readily carried to a warm location in the winter.
Only the healthiest geraniums from your garden beds should be potted up and pruned. Weak or ill ones are likely not to make it through the winter in a pot.
After pruning, always clean your shears to stop the spread of disease. Rinse well with a mixture of 1 part bleach to 10 parts water.
How should geraniums be cared for over the winter?
Geraniums have the advantage of easily entering dormancy, allowing for storage in a manner akin to that of sensitive bulbs. This method of storing geraniums for the winter entails digging the plant up in the fall and carefully removing the soil from the roots. The roots should not be spotless, just clear of dirt clumps.
In a room with a constant temperature of roughly 50 degrees Fahrenheit, such as your garage or basement, hang the plants upside down (10 C.). Rehang the geranium plant after soaking the roots in water for an hour once a month. All of the leaves on the geranium will fall off, but the stems will still be alive. Replant the dormant geraniums in the ground in the spring, and they will come to life.
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 fertiliser (ideally one with micronutrients). Geraniums’ yellow leaves can be avoided using fertiliser, 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 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.
