Hardy geraniums are bursting with flowers and have luxuriant foliage that gives the yard a great texture. They give a lot and demand very little since they are incredibly resilient, pest and disease resistant. The majority of hardy geraniums are absurdly simple to grow. They only need a soil that is well-drained and reasonably rich. In typical summer conditions, a few species are even reliably drought tolerant.
Some hardy geraniums have flowering seasons that last from late spring to late fall, which is quite long (if cut back hard after the first flush of blooms starts to fade in early summer). The better types will bloom constantly throughout the summer, bringing cheery color to your garden.
There are many different colors and textures to pick from to enhance the beauty of your landscape. Consider these top-performing types if you’re searching for a stunning, low-maintenance, hardy geranium that can withstand the seasonal difficulties. You’ll see that several of them have won the esteemed Royal Horticultural Society Award of Garden Merit!
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.

Height/Spread:
Depending on the type, they range from 5 to 8 inches in height for dwarf cultivars to 2 to 4 feet tall and wide for ivy varieties.
Exposure:
Most plants thrive in full sun. While zonals can handle moderate shade, regal types do prefer some partial shade. Some afternoon protection should be offered in excessively hot areas.
Bloom time:
Geraniums are prized for having a lengthy blooming period that can extend into the fall and begins in the spring. Plants may also bloom in the winter or the early spring if temperatures are kept above 45 to 50 degrees.
Color:
Flowers appear in a variety of colors, including reddish-black, mauve, orange, pink, purple, and white. The leaves of geraniums can be any color, including green, gold, chartreuse, bronze, red, and many other hues.
Are geraniums toxic?
The ASPCA claims that geraniums are poisonous to both dogs and cats. Vomiting, anorexia, sadness, and dermatitis are clinical indicators of intake or exposure. Plants should be kept out of reach of your pet at all times. view more common plants that are poisonous to dogs and cats.
Will geraniums bloom all summer long?
Geraniums look fantastic planted directly into flowerbeds, in baskets, or on posts. With proper care, they will continue to bloom all summer long and create a sizable bracket of blooms on robust stalks.
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.
Why do geranium blooms stop?
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.
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.
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.
