It’s presumably a plant that rises one foot from a clay container and has large globes of lipstick-red flowers and green leaves with scalloped edges. A geranium, that is.
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.
The plant in the garden is known as cranesbill and has the formal name of geranium. It has a brief blooming period in late spring or summer but can withstand extremely harsh winters. It is an evergreen.
These flowers are only related by name, and they differ greatly in terms of growth, beauty, and function. Although they are both members of the geranium plant family, they are not extremely similar to one another. The name “geranium,” which changed over time, serves as the link that unites them.
Annual geraniums need full sun from April through fall, as well as well-drained soil.
They appear best to me when grown by themselves or with a simple dusty miller border for contrast. Don’t transfer geraniums up to larger containers very frequently because they thrive in pots where the roots occupy the majority of the space.
Despite the fact that this plant is an annual, people frequently save their plants by putting the pots in a frost-free sun porch.
Native to a variety of climates, perennial geranium plants can be found in the Pyrenees highlands of Europe, Eastern and Midwestern North America, and Western Asia.
They should be placed permanently in the flower garden in full sun or very light shade, not in pots. They seem to benefit from protection from the summer’s intense afternoon heat, in my experience as a Piedmont gardener. Before you plant, give this some thought.
Provide moist, well-drained soil for these geraniums. Most cultivars reach a height of 18 to 24 inches. They are among the least fussy perennials because they don’t attract any pests or illnesses. They don’t need a lot of fertilizer.
As opposed to the annual geranium, expect a shorter flowering season. However, the foliage, which is typically notched, is lovely.
When planted close to tulips or daffodils, the foliage can spread out attractively and fill in some of the gaps as the foliage on the bulbs finally turns brown and vanishes.
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 can I tell if my geranium is a perennial or annual plant?
Are geraniums perennial or annual plants? Are you one of those customers at the garden center who has to pause and clarify the difference between an annual and a perennial? Unless gardening is our one and only true love, the truth is that we have all likely experienced it at some point.
A seasonal plant dies after going through one life cycle. A perennial plant endures for at least two years. Depending on where and how they are grown, geraniums can be either annuals or perennials.
The Latin term for geranium is pelargonium. These plants are typically grown as annuals since they cannot endure cold. However, they can be grown as perennials with a few simple techniques. In the following sections of this post, let us share a few of those tips with you.
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 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.
We hope that we have provided you with enough of tips so that you can continue to enjoy your geraniums year after year.

Can geraniums be kept in pots during the winter?
Geraniums are frequently planted in containers, which is a fantastic option if you want to overwinter them.
In the fall, before the first frost, if your geraniums are already in pots, you can simply relocate the pots under cover into a sunny, airy, and frost-free location, such a greenhouse or conservatory.
According to David Taylor, vice chairman of the UK Pelargonium and Geranium Society, “the best area would be a greenhouse and the ideal climate would be to have a heater in place to preserve temperatures above freezing when frost does threaten.” (new tab opens) (PAGS).
You can dig up, repot, and move the pots under cover if your geraniums were grown in a border.
Geraniums should always be pruned back before being brought indoors, whether they are already potted or have been removed from the border and repotted, according to David Taylor of PAGS.
“First, you should prune your plants back by roughly two-thirds; if lifting from outside beds, they could need to be pruned down by three-quarters or perhaps more. Do this pruning only while the roots are dry; otherwise, the remaining stems will wither.”
‘Also, get rid of any diseased, damaged, or dead sections you see. Make sure they are bug-free before bringing them inside for the winter,’ adds Emily Fernandes, a Californian small-space gardener and HouseGrail expert (opens in new tab).
Geraniums are best kept in a semi-dormant state while enclosed, as this means they won’t need as much water or food. “Place them in a partially sunny area, water them every two to three weeks, and maintain a humidity level of about 50%.” According to Emily Fernandes, a consultant at HouseGrail, “they go dormant over the winter like most other plants to store their energy for the growing season” (opens in new tab).
Do geraniums in pots reseed annually?
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.
A. Too little light or too much fertilizer are the two most typical causes of geraniums not blooming profusely. Geraniums are a sun-loving flower that require four to six hours of direct sunlight each day, or possibly longer in slightly filtered light. Typically, south and west exposures are ideal. The plant will frequently flourish in an environment with insufficient sunlight, but it will almost always grow taller or leggier as it strives for the light, and it won’t blossom as much. The amount of sun the plant receives has a significant impact on how many flowers it produces. In terms of fertilization, geraniums, like the majority of annuals, will grow enormous, lush green plants instead of a lot of blooms because the plant will be in a more vegetative state. Geraniums do well in containers if you feed them every three to five weeks. Use any of the water soluble fertilizers that are available, but make sure the mixture is balanced (10-10-10 or 20-20-20). Your geraniums will need to be fed less often in the ground; every 4 to 6 weeks should be adequate. It is much preferable to underfeed than overfeed if you are going to fertilize incorrectly.
A. The short answer is no, but some plants will do a little better in a less sunny location. Most Fancy Leaf cultivars with lighter-colored or white-colored leaf can handle a little less light, but they won’t grow in deep shade, and even if they do, they won’t bloom very much.
A. The size of your pots will play a role in this, but it would be greatest if you could alter the soil. Change at least half of larger planters, where that is more difficult, to “freshen” it up. Be sure to choose a soil that contains genuine soil when making your selection. Although a good base, many commercially available mixes that are soil-less require the addition of top soil or black dirt to create a little “heavier” mix that will hold a little bit more water. Due to how quickly smaller pots and containers may dry up in the heat, this is particularly crucial. Because they are so light in weight, the soil-free mixtures are frequently simple to spot in the stores. For the greatest results in your pots and planers, combine some potting soil with one of the soil-less mixtures. Any good potting soil will suffice.
A. Although you are not required to, doing so is unquestionably preferable. Here at the greenhouse, we refer to it as “dead heading,” and you should do it when the blooms are finished and will start to decay at the top, where they also start blooming. Simply take a gentle snap at the point where the blossom stalk joins the plant. This will only encourage the other buds to open up a little earlier because it will come off pretty readily.
A. To begin answering this question, we always mention that all of the geraniums we cultivate are cutting, or vegetative, geraniums. The method by which they are created or spread differs. Cutting geraniums are generated by a cutting, while seed geraniums are formed from a seed. Although it may seem relatively obvious, the differences in performance are likely what matter the most to the gardener. Cutting geraniums often have larger plants and blossoms, but seed geraniums are more slender and have single, more delicate blooms. Both have their functions, so gardeners should merely be aware of them when shopping. In bigger, mass plantings when a lower, extremely even height may be required, seed geraniums are frequently utilized. They are also occasionally used in smaller containers if they won’t significantly outgrow the pot over the course of a season. Cutting geraniums are bigger-growing plants with bigger flower heads that may fill out larger containers and compete with some of the more tenacious plants you might pair them with, like the helichrysum ‘Licorice Plant.
A. There are a number alternative responses to this topic, which is frequently posed. The first rule of gardening still holds true for many of our customers, who have been employing techniques for years that have been passed down through families. If it works, keep doing it. We’ve heard folks doing everything from shaking the soil off the plants to putting them in ice chests in the basement or upside down in brown paper bags in the attic. It was also suggested to look in the garage’s dry cleaning bags and an old dishpan under the ping pong table. As I previously stated, if these work, that is fantastic; nevertheless, geraniums are an annual plant. Geraniums don’t have a dormant season as a result, so people don’t put them to sleep for the winter instead of pulling them back from the brink in the spring. All of these examples show how resilient geraniums really are, but as they are annual plants rather than perennials, they do not die back and sprout new growth every year. Instead, they continue to expand from the same plant structure. So, after being saved for a few years, gardeners will notice that plants start to lose strength and start having smaller leaves and smaller, less frequent blooms. If you want to keep them, your best option is to take a few cuttings in the fall and grow new, fresh plants that you can move indoors for the winter and plant outdoors again in the spring. In essence, that is what we do in our greenhouse, beginning with new plants from cuttings every year in the late summer for the next year. But if it doesn’t work, consider bringing plants indoors and maintaining their growth. Simply cut the plant back by approximately 1/3 to 1/2 and bring it inside. You’ll need a light area, ideally a south or west window. You should water your geranium carefully, just like you would in the summer, and since there is less of a plant and there are less daylight hours, you may only need to do it once per week or once every ten days. Even so, as the plant searches for the light, you might notice some spindly growth; nonetheless, do not be alarmed. To have a bushier plant when it’s time to go back outside, just let the plant grow until the first or second week of March and then chop it down again. In addition, get them outside as soon as you can, even if you have to watch after them at night. Try one or more of these techniques; what have you got to lose? At the very least, it will be a worthwhile gardening experiment.
What are the raised, brownish bumps on the back of my ivy geranium leaves represent?
A. This physiological state is known as oedema (uh-DEEM-a), and it is brought on by cells that burst in the leaves as a result of the plant absorbing excessive amounts of moisture without transpiring. Ivy geraniums typically have a waxy feel, unlike conventional garden geraniums, which have a leaf that is thinner and more permeable. It results from a mix of air humidity, soil moisture, and simply more liquid than the cells can hold. The common misconception among gardeners that it is an insect-caused problem is unfounded. Because it only affects the underside of the leaves, it may only occur once or twice and go undetected. However, in severe situations, when it occurs repeatedly, the spots may pierce the leaf’s surface and eventually cause it to fall off. It most frequently occurs in overcast, rainy conditions. Growing your baskets without saucers will prevent them from sitting in water, and watering early in the day will give the plant time to dry out during the day. Purchasing additional kinds that are less vulnerable to oedema is another option. The Guillou variety, which were developed by the Guillou brothers and are identified as such on the tags, are among the best of them.
