Geraniums don’t care too much about soil types, preferring it to be moist and well-drained like other plants, but once established, they may live in the rain shadow of buildings, shrubs, or trees.
when to plant geraniums
Geraniums can be planted in the spring, from March to May, to establish themselves before the heat of the summer and provide you with blooms all season. In order to give them time to create a strong root system and begin blooming for you in the spring, you may also plant in the autumn between September and October when the soil is still warm.
Height/Spread:
Depending on the type, they range from 5 to 8 inches in height for dwarf cultivars to 2 to 4 feet tall and wide for ivy varieties.
Exposure:
Most plants thrive in full sun. While zonals can handle moderate shade, regal types do prefer some partial shade. Some afternoon protection should be offered in excessively hot areas.
Bloom time:
Geraniums are prized for having a lengthy blooming period that can extend into the fall and begins in the spring. Plants may also bloom in the winter or the early spring if temperatures are kept above 45 to 50 degrees.
Color:
Flowers appear in a variety of colors, including reddish-black, mauve, orange, pink, purple, and white. The leaves of geraniums can be any color, including green, gold, chartreuse, bronze, red, and many other hues.
Are geraniums toxic?
The ASPCA claims that geraniums are poisonous to both dogs and cats. Vomiting, anorexia, sadness, and dermatitis are clinical indicators of intake or exposure. Plants should be kept out of reach of your pet at all times. view more common plants that are poisonous to dogs and cats.
What geraniums work best in pots?
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.
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.

Do geraniums grow better in the ground or in pots?
Geraniums can be planted in any type of garden soil, but they thrive in neutral or alkaline soil. Grow in flower beds, hanging baskets, or containers that receive direct sunlight.
How to plant geraniums
Choose a peat-free multi-purpose compost with extra slow-release fertilizer when growing geraniums in containers. When paired with other summer bedding plants, geraniums look amazing. They may endure being packed closely together with other sensitive plants if planted in a rich compost and kept well-watered.
Here, Monty Don shows how to grow lavender and pelargoniums in pots for a lovely display:
In an apartment, how many geraniums are there?
Depending on the size of the plants or the pots they are put in, the number of flowers or other plants in a flat may change. Most nursery flats, according to the National Gardening Association, hold 50 plants.
Can geraniums be grown in hanging baskets?
Geraniums don’t have to be planted in hanging baskets, but people do like the way they look when they are cascading. Geraniums can actually be hung from baskets and pots to create a full live wall.
When you follow excellent watering practices, hanging geraniums are low-maintenance plants that are quite easy to grow. If you have a place to maintain them, hanging geraniums can be cultivated outside during the summer and brought inside for the winter. Ivy geraniums alone come in over 75 different cultivars (or types), giving you a sizable selection from which to build your garden residence.
Planting in a Hanging Basket
Comparing hanging baskets to pots or garden beds, there are several differences. You must be sure to utilize a light soil. You don’t want anything weighing the plant basket down more than necessary because it will be hanging from a hook. Make sure the container you purchase has at least one drainage hole because geraniums might rot in poorly drained soil.
You should make sure the basket is positioned in a location that receives sunlight for four to six hours every day, whether it is indoors or outside. Ivy geraniums are more delicate than other varieties, therefore if at all possible, place them in the morning rather than the afternoon to avoid sunburning the leaves and petals.
Wait until the temperature is constantly above 40 degrees if you’re planting them outside rather than hanging them indoors. Geraniums require little care, however they are sensitive to cooler temperatures and sunlight. Ivy geraniums, on the other hand, should only be left in places with full sun for as long as the temperature is below 80 degrees. You should try to shift them to regions with some shade if they frequently reach higher elevations (like during the height of summer), in order to prevent them from overheating or becoming damaged.
Growing Conditions
You should be sure to check on your hanging geraniums frequently throughout the hotter months in addition to giving them morning sunlight. They can survive in dry soil if you miss a day or two of watering, but they prefer a little moisture in the soil. To guarantee the optimal growth, maintain a generally consistent moisture level. The prevention of conditions like edema from weakening your plant will depend on maintaining an even moisture level (not too much or too little). These particular geraniums have a limited amount of soil to draw nutrients from because they are being planted in a basket. Ivy geraniums can be grown well without a water-soluble fertilizer, although it is advised that you apply one every ten days to aid in the growth.
Geraniums have a height range of 18 to 36 inches. You may enjoy blossoming flowers throughout the early fall if you take the proper care of them, making sure they receive the right amount of sunlight, temperature, and water. (Better even, you might get to enjoy them over the winter if you decide to bring them indoors.) To promote greater growth, you only need to make sure you prune and deadhead them as necessary. Deadheading is the practice of removing from the plant fading or dead blooms. You may encourage the plant to focus its efforts on producing new flowers by picking off the dead flowers. However, some claim that ivy geranium flowers clean themselves, so you might not need to deadhead them as frequently as you would other species.
A Step-By-Step Guide to Hanging Geraniums
Look no farther if you don’t know where to begin with your hanging geraniums! Below, you’ll find a step-by-step instruction manual. It starts with the basket’s construction and goes on until your porch is covered in lush, flowering geraniums.
- Select a basket. Make sure the basket you select has one or more drainage holes. A coco liner is commonly used in hanging baskets to keep the soil in place and increase drainage effectiveness.
- Identify an ivy geranium. Ensure that you receive the flowing impact that this version may offer. Other geraniums will still look lovely in baskets, but they will expand upward rather than outward.
- Start adding light soil with a high-quality mixture to the basket. You should use a rich soil to plant your ivy geraniums because there isn’t a lot of available soil for nutrients.
- Plant your ivy geranium in the basket once it has enough dirt in it. Make careful to add as much additional dirt as is required to maintain stability.
- Look for a location to hang your basket. It should be in a location with full sun to moderate shade, with morning sun being the most direct source of light. Avoid direct afternoon sunlight if you can to prevent the plant from being harmed. This place may be inside or outside.
- After locating a suitable spot, hang the basket there and water it. You should aim for wet soil. not too wet that you risk plant rot, not too dry that the geranium doesn’t have enough to live. Ivy geraniums should only receive water until it begins to leak through the bottom of the basket, which is a good general rule of thumb.
- To keep the plant happy and healthy, water as needed. Every day, you ought to check on your ivy geranium to see how it’s doing. In hotter temperatures, more water may be required because the soil will dry out more quickly. Note: If temperatures regularly rise to or above 80 degrees, you should shift your geranium from full sun to partial shade.
- Depending on how it grows, you might or might not need to deadhead the plant. Some claim it is unnecessary, but if the flowers begin to wither, make sure to remove them so the plant may focus its resources on flowers that are growing and healthier.
- You might be able to bring your plant inside to overwinter if it grows successfully. However, because geraniums are typically annuals, you’ll probably need to buy a new one the following year.
