Geraniums’ cheery pinks, reds, and oranges enliven gardens around the country. However, pelargoniums and geraniums are two distinct species that are frequently referred to as “geraniums.” While true geraniums have divided leaves and smaller, less noticeable blossoms, pelargoniums have broad, rounded leaves with colorful flowers. In reality, garden centers sell pelargoniums under the names Martha Washington, ivy, zonal, and scented geraniums. Any variety of geranium, hardy in Sunset Climate Zones 8, 9, and 12 through 24, thrives in summer gardens. Geraniums can be easily moved from 4-inch grower’s pots into larger flowerpots for your patio when grown as quickly-growing annuals.
In a bucket, combine perlite, compost, and potting soil in equal parts. The potting media has to be moist, so add water and mix. Fill an 8- to 12-inch flower pot to within 4 inches of the top with the damp potting soil.
Take the geranium out of the previous flowerpot. Slide the geranium with the root ball out of the pot by gently tipping the container onto its side. To fit into the new flowerpot, unwind any encircling roots and, if required, cut them.
As you fill the space around the roots with the leftover potting soil, plant the geranium in the new flowerpot while holding it in place. Till the root ball is completely covered, add potting soil. Gently tamp the ground close to the roots.
Water the flowerpot thoroughly until water is dripping from the bottom. When the top of the soil feels dry to the touch, keep watering at regular intervals. In hot or windy conditions, you might need to water the geranium every day if you planted it in a hanging basket.
Pull the mulch back 3 inches from the geranium’s stem and add 2 inches to the flowerpot’s top. On warm or windy days, mulch helps keep the moisture level in a flowerpot steady and reduces excessive evaporation.
Fill the saucer of the flowerpot with one inch of gravel. On top of the gravel, place the flower pot. The geranium should be placed in a protected area with six to eight hours of daily sunlight.
What should you do with potted geraniums over the winter?
Geraniums can be overwintered inside in three different ways: as a houseplant, as a dormant bare root, or as cuttings. Your decision will be influenced by the amount of room you have indoors and the range of temperatures you can tolerate. Here is a closer examination of each method.
Overwintering geraniums as houseplants
If you want to keep the entire potted plant and have lots of room close to a window that gets bright, direct light, go with this option. A drafty west-facing window would be the ideal place for your potted geranium to spend the winter because geraniums prefer it chilly (55 to 65 F is optimum).
Wash the foliage well with your hose and repot the plant in new potting soil to prevent bringing unwanted pests from outside. You might also use insecticidal soap, which is sold in most garden centers and hardware stores as well as online. Avoid taking the plant indoors if it shows any signs of pests or illness. Only strong plants have a chance of successfully overwintering indoors.
During the winter, keep the soil wet but not damp. No more humidity is required. If the stems begin to sag, pinch them back to keep the plant compact throughout the winter. When springtime comes around, you may start fertilizing once more and transfer the plant back outside as soon as the temperature reliably rises above 50 F.
Overwintering geraniums as dormant bare root plants
This is the most typical way to overwinter geraniums, but it won’t work unless you have a dark, dry place that stays around 50 degrees throughout the winter.
First, dig up your geranium before it freezes and shake the dirt off the roots. To stop mold from forming, let the plant sit and dry for a few days before storage. Before moving onto the following phase, the roots must be completely dry.
The roots should be kept in a dark, dry place that doesn’t get colder than 45 degrees throughout the winter. Geranium roots should be kept at a temperature of 50 F. You can keep them by doing:
- It has been customary for generations to hang the plants upside-down from the rafters;
- placing them on a shelf after wrapping them in newspaper or a paper bag;
- they were put in a cardboard box.
Step 3: Every month or so, look for mold, black leaves, or limp stems at the roots. Remove any plant or root components that are harmful. Most of the stems should endure the winter in good shape. Before re-storing them if they become too wilted, give them a good bath in water and let them air dry.
Step 4: Reviving your geraniums involves cleaning them up, pruning the stems back to healthy green growth, and replanting them in new potting soil about six weeks before your final frost date. Where the new roots will grow, bury the stems two nodes deep. When you notice fresh growth in one to two weeks, keep the plants somewhat dry; after that, keep the soil moist until the plants are big enough to replant outside.
Overwintering geraniums as cuttings
If your light windowsill area is limited or you are concerned that bringing in your entire potted plant would also attract unwanted bugs, this is a nice technique to try. Additionally, it’s a fantastic way to multiply your existing geraniums.
To trim plants, you’ll need:
- a cutting edge.
- Most hardware stores and garden centers sell rooting hormone, which is sold online.
- Use little terracotta or plastic pots, or recycle a clear takeaway container for roasted chicken.
- If you don’t eat chicken, use clear plastic bags to cover the pans.
Do geraniums regrow after the winter?
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 for the next year?
Pelargoniums from your garden can be overwintered in a number of methods. You may preserve these delicate perennials over the winter by placing them in some newspaper, a cardboard box, a paper bag, or a sunny windowsill, and they will blossom again the following spring and summer. I’ll go over your options and offer some advice for winter maintenance.

Are geraniums able to survive the winter in the ground?
- 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 should last year’s geraniums be planted?
Many gardeners grow geraniums (Pelargonium spp.) as perennials in frost-free locations like U.S. Department of Agriculture plant hardiness zones 10 through 11, where they are kept from one year to the next. These plants, like other perennial shrubs, can survive the winter with just a trim and some mulch. You can only preserve your geranium for another year if you bring it inside for the winter if you live in a cooler climate.
Prior to the first freeze in the early winter, dig up your geraniums with a shovel. Step on the shovel’s blade after inserting it on the exterior of the geranium root area to force it down. To remove the geranium roots from the earth, pull back the shovel handle. Shake the soil from the roots of the plant by lifting it by its stalks.
Put the geranium stems, roots up and foliage down, in a cardboard box. Place the box in a dry space in your home or garage that is between 50 and 60 degrees Fahrenheit in temperature. Throw away any dead leaves and withered stems, and use scissors to cut off any mold that develops on the plants.
Stems that appear dry should be submerged in water for two minutes. Replace in the exact same spot in the box after patting dry with paper towels. Up until six weeks before to the last frost, keep the geranium stems in their current location.
Fill a planting pot with soil-free potting mix that has enough drainage holes. Each geranium stem should have the top cut off, leaving just strong, green growth. The lowest two leaf nodes must be pressed into the medium until they are covered by the dirt. Put 1 inch of water on the plant. Only apply more water if the soil is dry about an inch below the surface. In two weeks, look for new growth. The geranium is prepared for outdoor replanting one month later.
In a bed with well-drained soil and at least six hours of direct sunlight, plant the geraniums. Put them in place at the same depth as in the pots. Weekly 1 inch waterings with 10-10-10 liquid fertilizer mixed in according to half the label’s instructions. In most cases, 100 square feet of flower beds require 3.35 ounces of liquid fertilizer to be diluted in 20 gallons of water.
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.
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.
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.
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.
