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.
How are indoor geraniums cared for?
when taking care:
- Light Place your geranium houseplants where they will get at least six to eight hours of direct sunlight per day in order for them to grow strong plants indoors and bloom. In order to maintain the plants healthy if you don’t have windows that receive enough sunlight, you can supplement with artificial grow lights for roughly 14 hours each day.
- soil and irrigation
- For your geraniums, use a soilless potting mixture. A light, loamy, well-drained potting soil is preferred by geraniums. In between heavy waterings, let the soil of your geraniums dry out quite well. These plants are highly susceptible to diseases including rust, blossom blight, and gray mold if the soil is kept excessively moist.
- Geraniums typically favor cooler temps. The ideal temperatures are between 55 and 70 degrees F (13 and 18 degrees C) during the day and 65 to 70 degrees F (18 and 21 degrees C) at night.
- FertilizerDuring the growing season, you should fertilize your indoor geraniums for healthy growth and blossoming. Use time-release fertilizers or an all-purpose liquid fertilizer once a month at about half intensity.
- Pruning and Pot Size
- Avoid overpotting geraniums because they want to be somewhat potbound. In order to promote a bushier plant, you should also cut back any lanky canes and pinch back the growth points.
How long can geraniums be grown indoors?
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.
A geranium grows outdoors or indoors.
Gardeners have traditionally favored geraniums. They smell wonderful, are colorful, and are simple to grow. How to cultivate geraniums in your house and garden is provided here!
(Note: This page is about Pelargonium plants, sometimes known as geraniums or storksbills. This is not a page about “hardy geraniums, also referred to as cranesbills.
Geraniums are normally kept indoors to overwinter, even if they may be kept outside throughout the warmer months of the year. In contrast, if given enough light, they can bloom all year long indoors.
Geranium or Pelargonium? A Case of Mistaken Identity
Early in the 18th century, Dutch traders who were traveling through South Africa brought the plants that we now refer to as “geraniums” to Europe. Botanists misclassified these new plants into the same genus because they resembled the hardy wild geraniums that are already present throughout Europe.
Botanist Carl Linnaeus of Sweden included them in the genus Geranium in 1753. Pelargonium, which refers to the long, sharply pointed shape of their seedpod, was used to reclassify these new “geraniums when it was later revealed that they differed from European geraniums in the shape of their petals, the number of stamens, and other features.
However, people still refer to them by their old common name, “geranium,” even if we really mean “pelargonium.”
- You can grow geraniums as annual blooms or as indoor plants. They can be kept outside in a sunny area throughout the warmer months of the year (between your local frost dates).
- If keeping geraniums as indoor plants, make sure to do so in the late summer or early fall when overnight lows begin to consistently fall below 55F. (13C).
- Pay great attention to the size and color of geraniums when purchasing them. Healthy stems and leaves will not be straggly or discolored on top of them or underneath them. A plant with evident insect indications should also be avoided. Mealybugs, whiteflies, and spider mites are typical indoor plant pests.
- To prevent root rot, put plants in containers with drainage holes.
- When planting in pots, use a well-draining potting mixture rather than heavy, clayey soil. Geraniums dislike being planted in mucky, compacted soil.
- Place the plants where they will receive 4-6 hours of sunlight per day for the best bloom.
How to Care for Geraniums
- After letting the soil somewhat dry between waterings, water it again well.
- Water plants significantly less throughout the winter, but make sure the roots are not completely dried up. Given a time of hibernation throughout the winter, when they consume less water and don’t grow as much, geraniums thrive. For additional overwintering tips, see the section below.
- Regularly deadhead spent flowers to promote blooming.
- Pinch back the stems to encourage bushiness and prevent legginess.
- Fertilize approximately every two weeks throughout the active growing months. Half-strength a fertilizer that is water soluble When the plant should be dormant in the winter, avoid fertilizing.
- Repotting geraniums can be done in the spring to promote new growth or if they appear to need revitalization.
Overwintering Geraniums
- If they receive plenty of sunlight, geraniums that have spent the summer outdoors can be kept indoors. The sun may not be strong enough in northern regions in late winter to promote buds on some cultivars.
- Lift the plants before the first fall frost (you can find your local frost dates here), and use a sharp, clean knife to shapely prune the stems back to about 6 to 8 inches. In the low-sunlight environment they are about to enter, they shouldn’t have to maintain substantial amounts of leaves. A simple technique to increase the number of your plants is to save a few stems for rooting.
- Place the “mother plant” in the smallest pot you can find—just big enough to hold the roots—and fill it with ordinary potting soil.
- The plants should be kept in the shadow for a week before being moved to a sunny location and kept cool.
- Geraniums thrive in temperatures between 50 and 60 degrees Fahrenheit (10 and 16 degrees Celsius) at night during the winter, but they can also withstand lows of 32 degrees Fahrenheit (0 degrees Celsius) and highs of 80 degrees Fahrenheit (27 degrees Celsius), provided they are kept relatively dry.
- Cut off all the old leaves when the spring growth begins.
Keeping the new growth alive is the only challenge that can compare to getting it to appear. Here is some assistance with that:
- Only offer tiny quantities of water when the leaves begin to droop. Don’t feed or fertilize the plants. These plants must have some downtime.
- Pinch back your overwintered geraniums in February if you want them to bloom by Memorial Day. Take the plants outside and move them to beds or pots, as you like, once warm weather returns and all threat of frost has passed.
- Containers are ideal for growing the Common or Zonal Geraniums (Pelargonium x hortorum) (as well as outdoors).
- Hanging baskets, window boxes, and containers are all extremely popular places to use Ivy-Leaf Geraniums (Pelargonium peltatum).
How to Root Stem Cuttings
The majority of geraniums readily take root from stem cuttings when placed in soil, sand, water, perlite, or another rooting medium.
- Make a slanted incision 4 inches below the tip of the stem, above the node where the leaves emerge, with a clean, sharp knife. Cut the grass immediately below a node. Remove all except two or three leaves, any buds, and the stipules that resemble leaves at the base of leaf stalks.
- To ensure that the cut end of the stem will seal and not rot, roll the stem cutting in newspaper or place it in the shade for 24 hours.
- Place the stem in a wet rooting media container and keep it there for two days in a warm, shaded area. Give the cutting indirect sun after that. Just as needed, moisten the medium.
- Apply crushed geranium leaves to small cuts to halt the bleeding.
- Scarlet geranium is the flower that speaks of foolishness. More floral meanings can be found here.
- You won’t have to worry about those bothersome bugs because geraniums are known to be harmful to Japanese beetles.
- Keep geraniums out of the reach of curious youngsters and animals (cats, dogs) as they might cause indigestion or vomiting.
Low light, overexposure, and underwatering are common issues. Yellowing leaves are a sign that you are watering your plants either too little or too much. Try to water the geraniums evenly in this situation, and transfer them to a more sunny location.
Can geraniums survive the cold inside?
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 are geraniums maintained indoors during the winter?
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.
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 frequently should indoor geraniums be watered?
Geraniums don’t need daily watering unless the soil where they are planted is evaporating that quickly. When the soil is left to dry out between waterings, geraniums flourish at their best. Overwatering can happen if the soil is kept damp at all times. If you don’t allow the soil dry completely, it can be challenging to determine when it’s time to add extra water.
- Typically, geraniums don’t need daily watering.
- Between waterings, let your geraniums’ soil dry out.
- Delay watering your geraniums if the soil is still wet from a recent downpour or precious watering.
- The soil may dry out in a day of intense heat. In this situation, daily geranium watering is OK.
Ensure that geraniums in pots or other bigger containers are properly drying out in between waterings. If the soil is still wet from the last watering, avoid watering. Several geranium diseases can be brought on by not allowing the soil to dry out between waterings.
Bring Inside as Houseplants
You can bring your potted geraniums (Pelargoniums) indoors for the winter if you have space for them in a sunny place.
While they require sunlight, they thrive in temperatures between 55 and 65 °F (12-18C). I have tremendous luck keeping the air around them a touch colder than the rest of the home with a west-facing window that is slightly drafty.
Dig Up and Repot if Desired
To make sure they are content, healthy, and bug-free, some preparation is needed.
- Before the first frost, dig up and container your geraniums if they are in the ground.
- If they are already in pots, you can repot them if you want, but first perform a rigorous pruning and a bug inspection (see below).
- Trim any extremely long roots or any unkempt root balls before potting.
- Put flowering plants in containers using potting soil made for them.
Hard Prune
- Cutting back the entire plant by between one-third and half is an usual recommendation.
- Any dead, broken, moldy, sick, or diseased pieces should also be taken out.
- If the plant is otherwise good and healthy, you can try keeping any buds or blossoms even though this harsh pruning is ultimately ideal.
