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 do you keep geraniums over 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 mold.
- Check the stems quickly at the same time; they should be stiff. Throw away any dried-out, shriveled 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.
Are geraniums evergreen?
Common kinds of perennial geraniums are hardy geraniums and cranesbill geraniums. Seasonal growth occurs in perennial plants. While they normally maintain their leaves all year in Mediterranean conditions, colder climates see them die back in the winter and bloom anew in the spring. Aggressive pruning should be done in the winter to stop woody spread and vigor loss. In USDA zones 1 to 9, most perennial geraniums thrive.
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 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.
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.
For the winter, should geraniums be pruned back?
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.
Can geraniums be grown 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.
Are geraniums seasonal or evergreen?
Geraniums actually belong to two different botanical subgroups. The perennial varieties are the real geraniums. The geraniums that most people envision when they go plant shopping are the annual bedding varieties with flowers that resemble lollipops and are mounted on stick stems. The plant genus Pelargonium includes several bedding plants. Ivy geraniums, aromatic geraniums, and Martha Washington geraniums are just a few of the numerous additional geraniums that belong in the Pelargonium genus.
Provide Full Sun
Make sure to give geraniums a lot of sunlight to encourage blossoming. A full day of four to six hours of sun will work wonders! Give your potted plants exposure to the south and west for profusion of blossoms.
Deadheading
Geraniums must be deadheaded in order to bloom all summer. To encourage the plant to produce new blooms, remove the spent flowers. To concentrate the plant’s energy on growing new flowers, cut off fading blooms and stems.
Don’t Grow in Large Pots
When growing geraniums, be careful not to choose pots that are wider than 7-8 inches. With enough soil held in place and a healthy plant that will continue to bloom, this size is ideal.
Remove Sick and Yellow leaves Regularly
Regularly remove the dead and yellow foliage to keep the plant looking tidy and to direct its energy toward growing new blossoms.
Apply High Potash Fertilizer
Feed geraniums a 9-6-12 mix to keep them blooming more. The high potassium concentration aids in photosynthesis by supplying nutrients evenly to every area of the plant. Dosage and directions should be found on the label.
Apply all-purpose liquid fertilizer that has been diluted to a fourth of its strength every 4-5 weeks while the plant is growing as well.
Water Only When the Soil is Dry
Keep the soil dry; geraniums are more susceptible to damage from overwatering than from underwatering. Remember to water when the topsoil feels a little dry to the touch. Ensure the container includes drainage holes as well.
How are geraniums maintained year-round?
The optimal conditions for geranium growth are full, straight morning sunlight and moderate shade from the scorching afternoon sun. Geraniums bloom profusely outside all year long in frost-free regions thanks to dry, warm days and temperate nights. Provide soil that drains quickly, has a pH range of 6.0 to 7.5, and is rich in organic matter. In order to prevent stem and root rot, good drainage is essential. In an underground garden, geraniums only require minimum fertilizer. Three applications of water-soluble 20-20-20 fertilizer during the summer are all that are required. Instead of watering the geraniums regularly, use a solution made by combining 1 tablespoon of that fertilizer with 1 gallon of water. Feed outdoor container geraniums every two weeks from spring through fall with the same fertilizer solution used for inground-garden geraniums since soil nutrients leak faster in pots than in the ground. Reduce fertilizing and watering when the light level drops.
