Geraniums are incredibly simple to store for the winter—just place them in a cardboard box or a paper bag and secure the top. The following advice will help them survive:
- Maintain geraniums in a cool, dry area with a temperature of 50 to 60 degrees F.
- Once a month or so, remove dried leaves from the bag or box and check for mold.
- Check the stems quickly at the same time; they should be stiff. Throw away any dried-out, shriveled stems you uncover.
- If you see that the plants are becoming really dry and crispy, give them a brief soak in water.
- Plants with stems that appear to be blackened or mildewed should be disposed away.
Geraniums are typically kept in a sack upside down. Although the exact cause is unknown, one idea holds that it does so by pushing moisture into the stems. Whatever the cause, storing them in this manner is neither harmful nor necessarily harmful.
Do you prune geraniums before the winter season?
Maintain their growth in containers. When given the right care and climatic circumstances, geraniums thrive readily indoors in containers. Reduce plants to half their original size before the first frost, then check them for pest or disease symptoms.
When should I cover my geraniums for the winter?
- 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.

How can you grow geraniums in a cold frame over the winter?
A cold frame offers a straightforward answer if you enjoy using delicate or tropical plants in your garden but are unsure of what to do with them in the fall.
Simply said, it’s not a greenhouse, so you won’t be able to keep your plants looking lush and beautiful throughout the winter. However, you can provide them the ideal circumstances throughout their dormant season so that, come spring, they’ll be ready to spring back into action and restart healthy growth.
Although alternative insulation materials, such as horticultural fleece, can also be useful, a sunken cold frame will prove to be the most effectively insulated because the ground will naturally offer the most constant temperature.
Before the first frosts, prune your delicate perennials as much as you can without harming the plant in order to put them in a cold frame. Move the plant, if it isn’t already in a container, into a sizable pot with room for the roots and a good layer of compost around them to protect them. Be very cautious to maintain the rootball intact.
Fill up any holes left by your pots in the cold frame with mulch or other insulation materials, such as shredded paper or polystyrene, or dried leaves. To assist prevent drying out and preserve moisture around the roots, water the pots, and then cover the tops. Although it’s important to take care not to overheat the cold frame as this would force your plants into growth far too early and may result in irreparable damage, composts, especially farmyard manure, emit heat as they degrade and can provide highly effective insulation. Always err on the side of caution.
You are responsible for managing the climate within the cold frame once all of the plants have been stored there. Never allow the pots to go dry, but be careful not to overwater as this could destroy the roots. Since they won’t be able to grow, the plants won’t be able to absorb very much water at this time. Keep the light levels low but not completely dark; covering the plants with a thin layer of fleece will assist to reduce the amount of light they receive and delay their premature growth.
Temperature swings can also be detrimental to dormant plants, therefore they should be avoided if feasible. A small opening in the lid will allow any surplus heat to escape if the outside temperature is between 25 and 30 degrees Celsius. For bigger temperature rises, you may need to further open the lid—just remember to close it before nightfall! Visit the website to view our complete selection of cold frames.
Your indoor plants will receive even better protection if you use a recessed cold frame or place it close to a windbreak; this is crucial if you have plants that keep their leaves throughout the winter.
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.
How much should I prune my geraniums back?
You should prune a perennial geranium after it has bloomed all season and starts to wither. This helps the plant store energy for the spring while simultaneously keeping it dormant for the winter. This could need to happen any time between August and late October, depending on your zone. Cut perennial geraniums down to 2 or 3 inches above the soil with a pair of trustworthy shears, ideally at nodes or new growth points. Take out any more flowers or foliage. You’ll have a collection of thick stems that is really ugly. But don’t panic, your blooms will return in full bloom the following spring.
Geraniums should be brought inside when?
Bring geraniums indoors before the first frost to overwinter them. Drag the entire pot indoors where they should stay for a few weeks while you take care of other more urgent garden tasks if you are growing them in a tub or container and have limited time (as it generally is in the fall). If they were grown in beds, simply remove them with a little dirt, place them in a pot, and water them sparingly. They will survive for a few weeks until you can deal with them.
Can geraniums be brought inside during the winter?
Pelargonium species, which come in pots, make great indoor plants that may be grown all year round. They normally become available in March through June, and if given enough light inside the house, they will bloom continuously. There are several fresh varieties, like vining and hanging basket cultivars. They are available in many different types of containers and at varying stages of development.
Will geraniums in pots reseed?
Geraniums have the advantage of easily entering dormancy, allowing for storage in a manner akin to that of sensitive bulbs. This method of storing geraniums for the winter entails digging the plant up in the fall and carefully removing the soil from the roots. The roots should not be spotless, just clear of dirt clumps.
In a room with a constant temperature of roughly 50 degrees Fahrenheit, such as your garage or basement, hang the plants upside down (10 C.). Rehang the geranium plant after soaking the roots in water for an hour once a month. All of the leaves on the geranium will fall off, but the stems will still be alive. Replant the dormant geraniums in the ground in the spring, and they will come to life.
How can I tell if my geranium is a perennial or annual plant?
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.
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.
