When you point to a geranium in a garden center, you are likely pointing to a Pelargonium, a type of plant that is frequently referred to as a “geranium.” According to botany, the genus Geranium, which includes real geraniums, is a related one of hardy flowering perennial shrubs. They are also referred to as cranesbills. The Geraniaceae family includes both geraniums and pelargoniums. In any event, we’ll continue to refer to the well-known flowering plant by its widely recognized common names, “geranium” and “pelargonium.”
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.

What makes geraniums unique?
Geraniums Can Survive Drought As long as they are placed in well-draining soil, these plants thrive in warm, sunny environments and require only moderate to frequent watering. They are great choices for container gardening because they require little maintenance.
A geranium is a type of flower, right?
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 in bloom all year long?
- Wet shoes are not good for geraniums. Do not place them in excessively wet soils or environments. The best benefits come from letting the soil get completely dry in between waterings.
- Avoid watering from above. Fungal illnesses will become less likely as a result.
- They may tolerate slight frosts in cool temperate regions. After each flowering cycle, lightly trim the plant to promote further blooms.
- When flowering is finished in the fall, harder pruning (one to two thirds of the plant) can be done.
- Cuttings from geraniums can be easily multiplied.
- Due to the intense oil content in the leaves, Ivy Leaf Pelargoniums are well recognized for deterring cats from gardens.
- There are numerous varieties of geraniums and pelargoniums. A few of these are: Common Geranium the market’s most popular variant. Large, green, hairy leaves with gorgeous flower flushes appear from spring to late summer, however they may bloom all year in some regions.
Pelargonium with Ivy Leaf Pelargonium with trailing growth, fragrant, ivy-shaped leaves, and tiny blooms. Excellent for use as a ground cover in hot, dry locations and in containers.
Aromatic Geraniums More so than their blooms, scented geraniums are grown for their leaves. Their leaves have a tiny furrow at the edge, which sets them apart from regular Geranium varieties and gives them a ruffled appearance. To release the oils and make a pleasant perfumed area in the garden, crush the leaves. Rose (P. graveolens), Apple (P. ordoratissimum), Peppermint (P. tomentosum), and even Lemon are among the many diverse smells and variations that can be found (P. citronellum). Some of them are even edible, so read the labels carefully before eating.
Pelargonium Zonal (P. hororum) This cultivar not only features attractive blooms, but also unusually shaped leaves. These set themselves apart from the other kinds by having zones or leaf outlines. These zones produce a distinctive feature plant for the garden or pots and can be simple (just two color forms) or complicated (three or more color forms).
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.

How long do geraniums in pots 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.
Where should geraniums be planted?
To cultivate geraniums, you don’t have to be an expert gardener. Geraniums don’t require much in the way of particular care and don’t care much for expensive fertilizers or niche soils.
For geraniums, soil
A loose soil with lots of organic materials is ideal for geraniums. Add peat, compost, or perlite if your soil is on the heavier side. Vermiculite and manure are not advised.
Geranium Planting Locations
Nearly all gardening zones are suitable for geranium planting. Even after understanding this, you might still wonder if geraniums require full sun. Geraniums need a lot of light to bloom, although in regions with hot summers, some shade is advised. The answer to the question of how much sunlight geraniums require varies on the particular geranium and your gardening zone. The optimum position has well-draining soil, morning sun, and afternoon shade. Pick a spot that is the right size for your geranium flower beds. The risk of illness is decreased by maintaining the proper distance between plants.
Geranium Planting Season
Planting season shouldn’t be rushed because geraniums aren’t cold resistant. If you hold off too long, though, you run the risk of missing the low nighttime temperatures that promote budding. Planting at the right time is the first step in understanding how to cultivate geraniums outdoors. Wait till your soil reaches 60 degrees F and the threat of the last frost has passed.
Geranium-specific fertilizer
Light fertilizing is required for geraniums. If you overfeed them, the blossoms will suffer while the foliage thrives. You don’t need to buy a specialized geranium fertilizer, despite the fact that you may notice it in your local garden center. Combine 2 teaspoons of a water-soluble 20-20-20 fertilizer with 1 gallon of water for a mild fertilization. Every three weeks during the growing season, apply this solution.
Geraniums in Containers
You may be wondering how to pot-plant geraniums. Actually, it’s as simple as putting them in the ground. You require a soil that is loose and well-draining, regular watering, and minimal fertilizing. As long as the container has drainage holes, geraniums thrive in various sizes and shapes of containers. The secret to growing geraniums in pots is to put them in sunny spots away from windy areas.
Geraniums grown in pots have the extra advantage that you may easily bring them indoors for the winter. Geraniums will flourish as a houseplant even in the coldest months if they are put in a sunny window. After the last frost, gently reintroduce them to the outside in the spring.
giving geraniums water
Take the time to leave an irrigation furrow around each plant to act as a watering reservoir since geraniums require deep, thorough watering. As a result, water can collect and then slowly percolate through the soil. Allow the soil to dry out in between waterings to prevent root rot. Using a soaker hose to water at ground level keeps water off the leaves and guards against illness. Geraniums need to be watered frequently because the soil in pots likes to get heated. You can water plants without waiting for the soil to dry up between applications since the drainage holes assist prevent root rot.
What volume of water do geraniums require? You’ll just need to keep an eye on your plants. Avoid allowing your geraniums to wilt for proper geranium plant care. Poor flower production and leaf shedding occur as a result of withering and revival cycles.
Geranium pruning
Outdoor-planted annual geraniums don’t require pruning, but routine deadheading can help reduce disease and boost growth. After the flowers have faded, simply pinch off the entire flower stalk and pick the plants’ dried leaves. The geranium houseplant frequently develops long, slender legs. Pinching the growth tips on a regular basis will promote branching.
Geranium Common Pests and Diseases
Geraniums are generally free of insects and other pests. Botrytis and other fungus attacks, however, can happen in cooler, rainier climates. Commercial fungicides offer some level of defense. Oedema and root rot are two issues that can result from overwatering.
Rose, The Queen Of Flowers
The “Queen of Flowers” is another name for one of the most well-known flowers of all time. Absolutely not just for girls, English gardens, or romantics! The amazing element rose is sometimes misunderstood. While the adjectives “feminine,” “floral,” and “powdery” have long been associated with roses, they do not exclusively describe their aroma. Some rose species also have “clean,” “masculine,” “woody,” even “fruity” undertones.
Rose in Perfumery
a strong flowery note. In addition to coming in a wide range of colors and sizes, roses are found all over the world. However, hybrid roses have unhappily lost their aroma as a result of the widespread cross-breeding of roses to produce a rainbow of colors. The two species of rose utilized in perfumery are Damascena and Centifolia. In perfumery, there are two different types of extracts for roses: absolute and essential oil (deeper and sweeter than its oil counterpart). Rose has endured because of its exceptional ability to meld with other floral, wood, and citrus notes.
Numerous chemicals are present in rose extracts, which explains why the fragrance is so complex and multifaceted. Citrusy (lemongrass) notes, green, fruity (peach, plum, wine), spicy (clove), amber, and sweet notes are all present in one single aroma of rose perfumery extracts.
Rose Essential Oil and Absolute
The essential oil from roses, especially Rosa centifolia or may rose and Rosa damascena or damask rose, is extracted using steam the same day after they are hand-picked in the early morning when the aroma is strongest. Rose water that hasn’t been utilized in the steaming process is frequently used in desserts, but you may also find it in some perfumes to give them a milder scent.
The most well-known countries for producing roses are probably Turkey, Bulgaria, France, and Morocco, but they aren’t inexpensive! The most expensive rose oil used in perfumery is the pure variety. It’s vital to avoid blending the same type of oil from different geographical places because the quantity of rain and sunshine a rose receives might vary its perfume. Otherwise, you might get something really intriguing.
Rose absolute, which is rose in its purest form, will provide you with the most robust rose profile of all of the varietals.
The Chemistry Of Rose
Each flower species is made up of a variety of components, some of which are in charge of imparting the aroma. Linalool, adlehydes, geraniol, and citronellol are only a few of the 300 compounds found in roses. Roses naturally contain rose oxide, a chemical with a metallic aroma. Watch out for the natural indole component, which can give rose oil a slightly rotting odor and is found in most flowers.
The world of perfumery is so exciting because of these compounds! You may not only duplicate the rose’s fragrance (at a lower cost), but you can also recreate the same rose repeatedly without worrying about its origin or harvest! Additionally, it means that you can generate an infinite number of rose scents that are not present in the actual blooms! The purest form of experimentation.
Geranium, A Masculine Rose
Strong-smelling comes from the Latin Pelargonium graveolens. And it definitely is!
When you think about geranium, images of flower boxes on window sills filled with lovely pink and red flowers sitting beautifully and filling the air with their perfume likely come to mind. The leaves, not the blossoms, are what give off the aroma. A geranium leaf will smell of citrus and fruit with a tinge of spice and, of course, a rose scent when crushed between your fingers.
Geranium is typically confused for “the other” rose because of its perfume, although it has a less powdery and more lemony, herbaceous aroma and a subtle but strong warm green scent.
Geranium in Perfumery
Its widespread use in soaps and lotions gives it a perfume that is thought to be “soapy,” which is why rose is also frequently utilized in fragrances for men.
The flower note geranium is excellent for tying together your top and base base notes and enhancing any other rose-based components in your composition.
Geranium Essential Oil
Geranium oil is made by distilling the leaves and stalks, much like rose oil. The drink smells crisp and vegetal green, with a pleasant undertone of mint and rose. It is far less expensive to obtain than rose!
Geranium, on the other hand, has an aromatic quality (similar to lavender), making it smell more “masculine” to some noses, whereas rose typically has a sweeter scent. Because of this, the extract is employed in numerous manly fragrances, as well as the typically masculine Fougere and Chypre accords, even though everyone seems to like its scent.
Noble geranium absolute, which is a richer, deeper extract than its essential oil equivalent, but also more expensive.
The Chemistry of Geranium
Citronellol, nerol, geraniol, and linalool—all well-known compounds in geranium oil—are among the numerous chemicals they share with rose, which explains why they have comparable fragrance profiles. Nerol, which is present in lemongrass and contributes to the lemony flavor of geraniums, and geraniol, which is one of the main ingredients in rose oil and gives geraniums their rosy aroma.
