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.
Do geraniums in pots reseed annually?
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 do you keep geraniums in pots from blooming?
Deadhead faded flowers on your geraniums by cutting off the entire flower stalk all the way to the point where it connects to the main stem.
Use a pair of sharp scissors, or even your fingers, to trim or pinch off approximately a half-inch of growth from the end of each stem to keep plants bushy, full, and jam-packed with flowers. This gives the plant a larger appearance and the potential for more flowers while also causing the plant to sprout two new stems.
Repotting your geraniums into a larger container only when necessary, and use a container that is just one size bigger than the previous one, as geraniums bloom best when they are relatively root-bound.
Geraniums are heavy feeders, so treat your plants with a balanced fertilizer as directed on the product label every few weeks during the spring and summer. At the conclusion of the summer, stop feeding.
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 healthy plants have a decent chance of overwintering indoors.
During the winter, keep the soil wet but not damp. No supplementary humidity is needed. If the stems start to stretch, clip them back so the plant stays relatively tiny over the winter. When spring approaches, you can begin to fertilize again and transfer the plant back outside once temperatures are consistently 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.
How long do geraniums last?
One of the most dependable types of garden flowers is the geranium (Pelargonium spp.). Around the world, they are grown as indoor plants, as garden annuals in USDA plant hardiness zones 2 through 8, and as perennials in zones 9 through 11. If given the right care, a common geranium can live for 40 years or longer. The most frequent causes of geranium death are overwatering or underwatering, insects or illness, and cold snaps. They might eventually grow long and unsightly, at which point they should either be replaced or removed.
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).
Do geraniums survive the cold outside?
- 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.

Do I need to remove the dead geranium flowers?
Without deadheading, the blooms will soon stop blooming and have a propensity to grow sparse. Additionally, this method stops the plant from producing new seeds. When your geranium blooms start to look weak or brown, you should deadhead them.
If you want to deadhead your geraniums, you need to go a bit further into the plant and snap the stem below the node or junction, where new growth starts. You have the option of using shears or only your hands. Healthy, well-watered plants have stems that are simpler to snap.
Deadheading will foster the growth of fresh, full blooms in place of any that appear weak or less full. Work your way through your plant, doing this in all of its parts. Within a few days, new, fresh blossoms will start to appear. The entire procedure just takes a few minutes, but it can extend the life of your plants by many weeks or even months. You can either pick a few stems each day while taking care of your plants, or you can do this every couple of weeks if you have the time.
Do geraniums bloom year-round?
Geraniums are profuse bloomers that require little maintenance and provide colorful flowers from spring till fall. In most zones, geranium plants are planted as annuals, however in zones 10 and 11, they are regarded as evergreen perennials. This well-known potted plant, which is native to South Africa and is frequently called a geranium, is actually a pelargonium. (For further information on the variations between geraniums and pelargoniums, see below.)
Provide Full Sun
Make sure to give geraniums a lot of sunlight to encourage blossoming. A full day of four to six hours of sun will work wonders! Give your potted plants exposure to the south and west for profusion of blossoms.
Deadheading
Geraniums must be deadheaded in order to bloom all summer. To encourage the plant to produce new blooms, remove the spent flowers. To concentrate the plant’s energy on growing new flowers, cut off fading blooms and stems.
Don’t Grow in Large Pots
When growing geraniums, be careful not to choose pots that are wider than 7-8 inches. With enough soil held in place and a healthy plant that will continue to bloom, this size is ideal.
Remove Sick and Yellow leaves Regularly
Regularly remove the dead and yellow foliage to keep the plant looking tidy and to direct its energy toward growing new blossoms.
Apply High Potash Fertilizer
Feed geraniums a 9-6-12 mix to keep them blooming more. The high potassium concentration aids in photosynthesis by supplying nutrients evenly to every area of the plant. Dosage and directions should be found on the label.
Apply all-purpose liquid fertilizer that has been diluted to a fourth of its strength every 4-5 weeks while the plant is growing as well.
Water Only When the Soil is Dry
Keep the soil dry; geraniums are more susceptible to damage from overwatering than from underwatering. Remember to water when the topsoil feels a little dry to the touch. Ensure the container includes drainage holes as well.
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.
Geraniums can they survive the winter inside?
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.
