The majority of geraniums used in florist arrangements are Martha Washington geraniums (Pelargonium x domesticum), which are stunning but difficult to grow plants with bright green, serrated leaves and impressive blooms in shades of pink, purple, red, white, or yellow, frequently with contrasting markings in the center of the flower. When the blooming ceases, Martha Washington geraniums are typically discarded, but given the appropriate conditions, they can last up to three years. Plant hardiness zones 9 through 10 of the United States Department of Agriculture allow for the perennial growth of Martha Washington geraniums.
Do Martha Washington geraniums survive the winter?
Burpee’s 2014 geranium release, “Angel’s Perfume,” has a pleasant, zesty lemon aroma to it. Backing the crimson flowers are wavy, cool-green foliage. What’s more, this geranium can tolerate both shade and direct sunlight. The plants’ height and width increase by 12 to 14 inches.
Thanks to their hardy nature, wintering geraniums are not difficult to master. You can get a head start on the garden season the following spring and save some money by keeping these plants dormant or treating them like houseplants. Find out how to care for geraniums over the winter.
For overwintering, pick geraniums from the Pelargonium genus. In addition to ivy, scented, or seed geraniums, this also applies to zonal or cutting geraniums. Although they belong to this category, Regal or Martha Washington geraniums typically don’t overwinter well. When the flowering season on these popular cool-season plants comes to an end, treat them as real annuals and compost them.
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.
Can Martha Washington geraniums be planted in the ground?
The Martha Washington geranium is a cool-season geranium that will broaden your geranium horizons (Pelargonium x domesticum). These geraniums, also referred to as regal geraniums, have vibrant flowers with petals that resemble velvet and are noted for their regal appearance. The exquisite ruffled look on the petals adds to the rich appearance of the plants.
The lavender, pink, burgundy, and purple hues of Martha Washington geranium blossoms fall under the reddish-purple color spectrum. Along with a variety of beautifully painted bicolor blooms, white can also be found in the mixture of blossoms. White centers or solid petals with white edges are two prevalent motifs.
The leaves of Martha Washington geraniums are bright green and slightly ruffled. When crushed, the leaves give off a citrus scent and the edges are frequently serrated. The height and width of Martha Washington geraniums range from 12 to 18 inches overall. A Martha Washington geranium frequently appears to be overflowing with flowers due to the flowers’ clustered appearance, which is similar to zonal geraniums but with stems that are typically shorter.
When the air is below 60 degrees Fahrenheit, these lovely bloomers thrive. When the nighttime temperature falls between 50 and 60 degrees, Martha Washington geraniums begin to set their bloom buds. As a result, they are well-liked as springtime plants and are frequently purchased as gifts for springtime occasions like Mother’s Day and Easter. Plants typically stop blossoming once summer temperatures approach. Plan to remove plants from pots or planting beds as the heat builds and replace them with classic garden or zonal geraniums if you like the way Martha Washington geraniums look and live somewhere where summers can get a little hot.
Fertile, well-drained soil is preferred by Martha Washington geraniums. Before planting, enrich the soil in landscape beds with a lot of organic matter. Use a commercial soilless mix made for planters in containers. These mixtures offer the proper drainage for containerized plants to flourish. Because Martha Washington geraniums are prone to root rot, don’t overwater them or place them in planting beds with lots of clay soil.
Put your Martha Washington geraniums in a location with direct sunlight, but keep them away from the hottest afternoon sun in all areas. Plants produce fewer flowers when they receive less sunlight. Remove spent blossoms to promote the development of new flowers. This reduces the growth of fungus on decaying flowers. Remove and kill the affected plant sections if you notice any indications of fuzzy mold-like growth (botrytis) on Martha Washington geraniums or orange or brown stains on leaves.
On Martha Washington geraniums, stay away from high-nitrogen fertilizers. Choose a fertilizer that helps promote blossom production, such as a bloom booster. It also works well to use a high-potassium fertilizer intended for veggies. The first number, which shows the nitrogen content, should not be more than half of the other two numbers on the fertilizer bag. For instance, using fertilizer with the label 10-10-10 is incorrect. Use a product with a label like 4-8-10, which is often a fertilizer for flowers and/or vegetables, or 2-4-1, which is typically a fish-based plant food.
Can I store my geraniums for the following season?
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.
Can geraniums be kept in pots during the winter?
Geraniums are frequently planted in containers, which is a fantastic option if you want to overwinter them.
In the fall, before the first frost, if your geraniums are already in pots, you can simply relocate the pots under cover into a sunny, airy, and frost-free location, such a greenhouse or conservatory.
According to David Taylor, vice chairman of the UK Pelargonium and Geranium Society, “the best area would be a greenhouse and the ideal climate would be to have a heater in place to preserve temperatures above freezing when frost does threaten.” (new tab opens) (PAGS).
You can dig up, repot, and move the pots under cover if your geraniums were grown in a border.
Geraniums should always be pruned back before being brought indoors, whether they are already potted or have been removed from the border and repotted, according to David Taylor of PAGS.
“First, you should prune your plants back by roughly two-thirds; if lifting from outside beds, they could need to be pruned down by three-quarters or perhaps more. Do this pruning only while the roots are dry; otherwise, the remaining stems will wither.”
‘Also, get rid of any diseased, damaged, or dead sections you see. Make sure they are bug-free before bringing them inside for the winter,’ adds Emily Fernandes, a Californian small-space gardener and HouseGrail expert (opens in new tab).
Geraniums are best kept in a semi-dormant state while enclosed, as this means they won’t need as much water or food. “Place them in a partially sunny area, water them every two to three weeks, and maintain a humidity level of about 50%.” According to Emily Fernandes, a consultant at HouseGrail, “they go dormant over the winter like most other plants to store their energy for the growing season” (opens in new tab).
How can winter geraniums be kept alive?
Geraniums can live for the majority of the winter without soil, which sets them apart from most annual flowers. Due to their thick, succulent-like stems, geraniums may withstand prolonged periods of dryness if they are handled correctly to prevent illness.
How to Store Geraniums
- Before the first harsh cold of the season, remove the plant from its outdoor container and gently shake the soil from the roots.
- Reduce the plant by roughly 50%, taking care to remove any unhealthy-looking growths, flowers, or dead leaves.
- For the winter, pick a cool, dark spot, such as an unheated basement, garage, or shed. It is crucial that the temperature stay above 45 degrees F.
- The plant should be hung or put in paper bags. If you decide on using bags, don’t close them too tightly; you want some air to flow through them. When geraniums are overwintered, mold can grow on them. When hanging plants, The Spruce advises leaving enough space between them so that air can flow around them.
- Put tags (loosely) around the roots of your plants to identify them by color, or group them according to color while storing them.
Care for the Dormant Geraniums
- Take the plants out of the bags and give the roots a 1- to 2-hour soak in warm water. I’ve seen some professionals advise doing this once a month, while others advise doing it a few times during the winter. Before putting the plant back in the paper bag, give it time to completely dry. THIS IS ESSENTIAL.
- Even if the leaves are withering, check the geranium stems every two weeks to make sure they remain firm. You should discard any plants with withered stems right away. Anything with mold on it should be thrown away.
Reviving After Dormancy
- Trim any dead stem tips, and get rid of any roots that are too lengthy.
- Before potting, bare root plants can be given an extended soak in water to rehydrate the roots.
- Six weeks before the last frost, plant geraniums.
- When planting, bury the plant two leaf nodes deep in moist potting soil to encourage root development.
- Give them plenty of water.
- To reintroduce light and encourage fresh growth, place the newly planted geraniums in a sunny window. After inactive storage, it will probably take the plants 2-4 weeks before they begin to grow.
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.
A perennial geranium is what kind?
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.
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.
What are geraniums of Martha Washington?
A Martha Washington geranium: what is it? These lovely, trailing plants, often known as regal geraniums, have ruffled, bright green leaves. Bright pink, burgundy, lavender, and bicolors are just a few of the many red and purple hues that may be found in blooms. Growing Martha Washington geraniums is simple, but the plants need a little more attention and have different requirements than regular geraniums. For instance, Martha Washington regal geraniums require nocturnal temperatures of 50 to 60 degrees F in order to bloom (10-16 C.). Learn how to grow this type of geranium by reading on.
