Geraniums are a wonderfully traditional plant that have been a gardening staple for well over a century. Geraniums are still one of the most widely used plants since they are the traditional choice for beds, borders, and containers. Traditional bedding is comfortable in warm weather and resilient in arid environments. In Zones 1011, geraniums are perennials even though they are often planted as annuals. If you’d like, bring them inside to overwinter, and then replant them outside in the spring. (Alternatively, if they receive enough light, they can bloom all year long inside.)
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 distinguishes my geraniums as perennial or annual?
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.
Do geraniums live forever?
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.
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.
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 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 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.
What kind of plant is a perennial geranium?
Perennial geraniums come in a variety of hues for both the foliage and the flowers. Cranesbill is one of its common names, derived from the way these plants’ seedpods look like a crane’s beak. The flowers have pink, purple, and even blue hues. A few also provide white flowers with stars. The flowers’ numerous hues are accompanied by darker hued veins that protrude from the center of several of them, resembling hand-painted whiskers. Early to late spring is when perennial geraniums bloom, and they continue to flower into mid-summer. A few types, nevertheless, continue to bloom into the fall.
Do I need to trim back my perennial geraniums?
reducing after blossoming After flowering, early-flowering perennials like geraniums and delphiniums are pruned to almost ground level to promote new growth and late-summer blooming. Then, in the fall or spring, these are again pruned.
What two varieties of geraniums are there?
Based on the size and characteristics of its flowers and leaves, geraniums can be broadly divided into four categories. These include regal geraniums, ivy-leaved geraniums, scented geraniums, and garden or zonal geraniums. There are distinctive qualities for each variety.
The mourning widow geranium, angel geraniums, wood geraniums, and meadow geraniums are a few further popular varieties. Below, a thorough description of each sort is provided.
