But so is this: a low-growing, sprawling plant blooming in a flower garden with tiny, five-petaled flowers that are either white, pink, blue, or purple. The potted plant’s common name is geranium but its legal name is pelargonium. Although it blooms all summer, it typically does not endure the winter. It’s a yearly.
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.

How long do geraniums 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.
Do geraniums continue to bloom each year?
Geraniums are profuse bloomers that require little maintenance and provide colorful flowers from spring till fall. In most zones, geranium plants are planted as annuals, however in zones 10 and 11, they are regarded as evergreen perennials. This well-known potted plant, which is native to South Africa and is frequently called a geranium, is actually a pelargonium. (For further information on the variations between geraniums and pelargoniums, see below.)
Are geraniums perennial plants?
Despite being perennials, geraniums (Pelargonium spp.) are delicate plants that can only endure year-round in the temperate climes of U.S. Department of Agriculture plant hardiness zones 9 through 11. Geraniums are frequently maintained as annuals in milder climates.
How can I save my geraniums for the following season?
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.
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.

What should you do with geraniums in pots throughout the winter?
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 drafty 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 centers 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 fertilizing 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 mold 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 mold, 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 centers 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.
Are geraniums deadheaded?
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.
How do you keep geraniums in pots from blooming?
Deadhead faded flowers on your geraniums by cutting off the entire flower stalk all the way to the point where it connects to the main stem.
Use a pair of sharp scissors, or even your fingers, to trim or pinch off approximately a half-inch of growth from the end of each stem to keep plants bushy, full, and jam-packed with flowers. This gives the plant a larger appearance and the potential for more flowers while also causing the plant to sprout two new stems.
Repotting your geraniums into a larger container only when necessary, and use a container that is just one size bigger than the previous one, as geraniums bloom best when they are relatively root-bound.
Geraniums are heavy feeders, so treat your plants with a balanced fertilizer as directed on the product label every few weeks during the spring and summer. At the conclusion of the summer, stop feeding.
Is it possible to keep geraniums 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.
Bring Inside as Houseplants
You can bring your potted geraniums (Pelargoniums) indoors for the winter if you have space for them in a sunny place.
While they require sunlight, they thrive in temperatures between 55 and 65 °F (12-18C). I have tremendous luck keeping the air around them a touch colder than the rest of the home with a west-facing window that is slightly drafty.
Dig Up and Repot if Desired
To make sure they are content, healthy, and bug-free, some preparation is needed.
- Before the first frost, dig up and container your geraniums if they are in the ground.
- If they are already in pots, you can repot them if you want, but first perform a rigorous pruning and a bug inspection (see below).
- Trim any extremely long roots or any unkempt root balls before potting.
- Put flowering plants in containers using potting soil made for them.
Hard Prune
- Cutting back the entire plant by between one-third and half is an usual recommendation.
- Any dead, broken, moldy, sick, or diseased pieces should also be taken out.
- If the plant is otherwise good and healthy, you can try keeping any buds or blossoms even though this harsh pruning is ultimately ideal.
