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.)
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
To keep geraniums flowering more, feed them with a 9-6-12 combination 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 often do geraniums bloom each year?
The numerous Geranium species may have slightly variable bloom times, but they all tend to bloom in the spring. For instance, the wild geranium (Geranium maculatum), which thrives in USDA zones 3 to 8, blooms between April and May, according to the Missouri Botanical Garden. The bloody geranium (Geranium sanguineum), which thrives in USDA zones 3 to 9, blooms between May and June, according to the Missouri Botanical Garden. According to Missouri Botanical Garden, the zonal geranium (Pelargoniumhortorum), which thrives in zones 10 to 11, blooms freely.
Numerous varieties of geraniums are kept indoors during the winter months before being moved outside during the warm months. Geraniums can bloom all year long if kept indoors and given ample light. To get the most flowers and to promote bloom production, situate them ideally where they may receive four to six hours of daily sunlight and deadhead the plants on a regular basis.
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.

Do geraniums flower throughout the winter?
I DON’T WANT TO BE BURDENED WITH TIRED, OLD, MONSTER-SIZE PLANTS WHEN IT COMES TO OVERWINTERING GERANIUMS. Fresh, young, eager-to-grow geraniums that are manageable in size for the window garden’s ornamental purposes are what I’m after. Do you share my desire? Then allow me to precisely demonstrate how to prepare these common summer plants for interior winter splendor.
A suitable time to restore and propagate zonal and scented-leaved geraniums is in the middle of August or at least six weeks before the first anticipated frost. This provides the plants plenty of time to heal from root stress and for cut stems to develop roots before the major shift from the outside to the inside.
I’ve never had a problem with the restoration and propagation techniques listed below:
Cut the plant back to within an inch of its life, or to the point where the lowest leaves may be discovered, when working with a zonal geranium that has grown all summer (like “Puritan White” above). Be harsh here.
Your plant should resemble this once virtually all of the top growth has been removed.
Pull the geranium out of its pot next. Place one hand over the plant’s top, where it may support the soil and top growth, to do this in a “professional manner”. Invert the pot next, and while keeping the base in place with your other hand, strike the rim of the pot against a hard surface.
It’s likely that you’ll find the plant to be extremely root-bound. We’ll take care of this.
Slice the roots in thirds using a sharp knife. You should cut away roots in direct proportion to the amount of foliage that has vanished.
After that, cut vertically to cut through the dirt and roots as shown above. The objective is to be able to center the plant in its previous pot with a one-half to one-inch space between the dirt now present and the pot’s walls.
Now carefully examine your geranium. Do you notice any rotten or dead stems? Cut off these. Only three or four stems that exhibit signs of vitality are required.
Then fill the pot with additional potting soil until it reaches about halfway up the edges.
Put the plant in the pot’s center now. If centering appears to be unattainable, then remove more soil and roots to produce a rounded form.
Afterwards, secure it with a paintbrush, a Popsicle stick, or a plant label (as above).
When planted correctly, there should be a one-inch space for watering between the soil’s surface and the pot’s top.
Thoroughly soak the plant until extra moisture drains out of the drainage hole. Remove any soil that is adhering to the leaves by rinsing them.
That’s all, then! You now possess a freshly restored geranium that will bring you joy during the rest of the winter.
What should we deal with all the stems that we cut now? All right, each of these can develop into a new plant.
The stems should then be left alone for a few hours (or perhaps a few days) to allow the cut end to “callus,” or dry out. It is unlikely that a callused cut will decay.
Stipules, or the little flaps along the stem, should also be removed. These could decay in soggy ground.
There isn’t a picture for the following three steps because I don’t believe you need it: Take a 4-inch clay pot, and cover the drainage hole with a piece of shattered pottery. Then add a new mixture to the saucepan.
To a depth that roughly corresponds to the length of your cutting, press a pencil into the earth in the center.
And then, use your thumbs to firmly press the earth down. Or “thumb,” if you are working while holding a camera.
Just add a little more mixture and adjust the stem if, after pressing down, the soil level lowers more than an inch below the top of the pot.
Give the plant plenty of water (until excess drips through the drainage hole). Simply spray the leaves once or twice daily until roots grow if wilting symptoms appear. When new growth is visible, your cuttings will have taken root.
Place the plant outside in a well-lit but dim area. After the young plants have developed roots, you can move them to a location that gets half-day sun (or full-day sun in a window garden).
By the way, perfumed leafed geraniums can be propagated and restored using the same techniques. Unfortunately, they are becoming rarer by the day, therefore the only way to ensure that you will have them from year to year is to propagate them. My rose-scented “Lady Plymouth” is shown above. This variety’s leaves can be crushed and added to your bathwater. You can also prepare scented icing for cakes and cupcakes by steeping the leaves in full-fat milk.
You can view images of the scented-leaved and large-flowered geraniums I’ve used in my many winter window gardens throughout the years by visiting the houseplants category on this website. The lavender-pink “Americana” made a lovely sight in my music room window in December 2011.
America appears beautiful in my herb garden as well. It recently drew a hummingbird moth here.
Indoor Culture: Give your geraniums as much direct sunlight as an east or south window will allow for indoor success. While plants grown from cuttings often don’t set buds until the days become longer in February or March, restored plants can bloom as early as December. In February 2008, I grew zonal, scented-leaved, and fancy-leaved geraniums in the window of my library/den.
You don’t have an east or south window? Put the plants in front of some fluorescent lights. I can tell you that zonal geraniums will bloom in January virtually as well as they do in summer if they are illuminated for 16 hours each day.
Once the plants are established, I use a high-phosphorus, low-nitrogen plant food to promote flowering. One and a quarter teaspoons of formula per gallon of water are fed to the window garden test subjects. Due to their prolonged exposure to light, I raise the food for the window garden plants to one and a half teaspoons.
Well. I sincerely hope that this tutorial was at least somewhat helpful to you. Maybe you’ll tell me by posting a remark. Your words are the light of my life as always.
Do you need to remove the dead geranium flowers?
Of course, removing all the dead blooms will immediately improve the appearance of your plants, but there are additional benefits to understanding how to deadhead geraniums.
Your geranium will focus all of its energy on producing seeds if you leave the dead flowers on it rather than producing new blooms. By cutting them off, the plant may focus its efforts on developing new blossoms. Therefore, if you keep up with the deadheading, you’ll have enough of new flowers all summer long for your hanging basket ideas or other displays.
Additionally, keeping them organized in this way enhances the air flow around the plant. This lessens the risk of the widespread fungus illness botrytis blight.
