Pelargoniums die in the winter and are frequently treated with a fungicide, but true hardy geraniums come back each year. The best way to tell if a plant is a perennial is to look at its leaves. If the leaves are green, it’s a perennial. The leaves will turn brown if the plant has not been watered for a long period of time, or if it has been exposed to extreme heat or cold.

Do potted geraniums come back every year?
Geraniums will take off in the spring if you save them for next year and store them in a cardboard box or a paper bag during the winter. If you don’t have a box, you can use a plastic bag with a hole cut in it.
You can also cut a piece of cardboard and put it over the top of the box. This will make it easier for you to dig up the plants.
What kind of geraniums are perennial?
Perennial geraniums comprise a large collection of more than 300 species and varieties that go by a number of names, including hardy, wild, and cranesbill. States, the most common species is Geranium officinalis, which is native to North America. It is also found in Europe, Asia, Africa, and South America, as well as parts of Australia and New Zealand.
U.S., it is most commonly grown as an ornamental plant, but it can also be used as a ground cover, a drought-tolerant shrub, or a houseplant. Geraniol, an oil extracted from the seeds, is used to treat a variety of skin conditions, such as eczema and psoriasis. The seeds are also used in traditional Chinese medicine for the treatment of rheumatism and arthritis.
What do I do with my potted geraniums over winter?
Geraniums are very economical to keep frost free, so they can be kept in the greenhouse. To make sure temperatures stay above freezing, we recommend using a heater. If the stems get frosted then the plant will die and you will have to start over with a new plant.
If you want to keep your plants in a greenhouse, you can use the same method as above, but instead of using an air conditioner, use a fan to circulate the air around the plants. This will help keep the temperature of your greenhouse at a comfortable level.
How do I save my geraniums plants for next year?
Place one or two plants in a large paper sack and store them in a dry location. The plants can be hung upside down in a dark place. The seeds will germinate in two to three weeks, depending on the type of germination medium you use. If you are using a soil-less medium, you will need to wait until the next spring to plant the seedlings.
How many years do geraniums last?
The average life expectancy of a geranium is about two years and although they will last much longer than that, they tend to get woody and diminish in bloom. Simply take four-inch stem tip cuttings with at least two pairs of leaves and place them in a warm, dark, well-ventilated area. They will germinate within a few weeks.
Geranium seeds are available at most garden centers and nurseries. Geranium seedlings can be grown in containers, but they are best grown outdoors in full sun. If you want to grow them indoors, you will need to provide them with plenty of light and water.
Can geraniums survive outside in winter?
While they can survive light frosts (temperatures just below freezing), they will die if exposed to prolonged temperatures below freezing so need to be stored in a cool, dry place away from direct sunlight.
How many years do geraniums flower?
As long as it’s well cared for, the true lifespan of the geranium can be many years. They can be left outside for a while. Geranium maderense is a biennial that has a lifespan of only two to three years, but will survive most winters. Geraniums are often used as ornamental plants in homes and gardens, but they are also a great addition to the landscape.
Should I cut back my potted geraniums?
If you keep your geraniums year-round, whether indoors or out, you’ll want to trim them in the spring and fall. Perennial types tend to become leggy over time, so they need the most pruning. To keep them looking their best, you need to provide them with some shaping. The best way to do this is to prune the stems at the base of the plant.
This will help to keep the stem from getting too long and will also keep it from growing out of control. It’s also a good idea to remove any dead or diseased stems that may be growing in your garden. If you don’t have the time or patience to take care of them yourself, a friend or family member can do it for you.
