Can You Grow Hardy Geraniums In Pots

Can hardy geraniums be grown in containers? This query has recently come up from new gardeners.

Without a doubt, the response is YES! You can definitely plant your favorite hardy geraniums—say let’s Geranium Rozanne—in your favorite garden containers. Rozanne enjoys dripping from window boxes and hanging plants. She also enjoys leaning over the edge of large planters. As it turns out, container gardening is a great way to highlight Rozanne’s best qualities. Here are some justifications on why this may be the best option for you.

Are geraniums 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.

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.

How are hardy geraniums cared for?

Hardy geraniums can be grown in the sun or the shade in moist but well-drained soil. After flowering, prune back the plant to promote a second flush of blooms. Hardy geraniums wither in the fall and reappear in the spring. Plants will continue to grow well for several years if they are mulched annually with leaf mold, well-rotted compost, or horse manure.

Are geraniums suitable as pot plants?

Few flowers in a pot look as wonderful as these ones do. Large clusters of magnificent blooms in shades of red, pink, rose, salmon, orange, lavender, violet, or white are mingled with attractive foliage. Although geraniums are frequently used as bedding plants, we believe they thrive in containers.

2 primary plants You can certainly find four or five distinct types of geraniums if you scour enough garden centers. However, two are responsible for practically all of the sales. The common geranium is the first and most widely grown (Pelargonium x hortorum). Because of the burgundy ring that frequently surrounds its rounded, velvety, green leaves, it is also sometimes referred to as a zonal geranium.

Common geraniums are typically treated as annuals, although in parts of the Southern Coastal and Tropical regions where it doesn’t freeze, they are perennials. Age causes succulent stems to turn woody, and plants develop into attractive shrubs. If you want to grow plants this manner outside of these places, you must keep the plants indoors, next to a window, during the winter.

The ivy geranium (P. peltatum), so named for its glossy green, ivy-shaped leaves, is the second most popular variety. This geranium cascades in growth as opposed to growing erect like regular geraniums. Use it to jump from window boxes, hanging baskets, or the edge of a large planter.

How To Grow Geraniums prefer rich, organically-rich soil that is fertile and well-drained. Between waterings, let the soil become just a little bit dry. Avoid overfertilizing: Feed them with liquid 20-20-20 fertilizer three times throughout the growing season or slow-release, granular fertilizer once in the spring. To keep the plants blooming, regularly remove fading blossoms. The ideal exposure is early full sun with afternoon mild shade.

Ideally Known These plants may suffer damage from the intense summer heat. In hot temperatures, many common geraniums stop blooming, a phenomenon known as “heat check.” (When cooler weather hits, they’ll start flowering again.) Grow heat-tolerant varieties like the Americana, Eclipse, Fidelity, Maverick, and Orbit Series to prevent this. Even less tolerant to excessive heat are ivy geraniums, which thrive in the Upper and Middle South. However, across a large portion of the Lower South, the heat-tolerant Blizzard, Cascade, and Summer Showers Series perform well. Likewise, “Sofie Cascade.” Ivy geraniums can be grown as winter annuals in the coastal and tropical South.

What is the lifespan of geraniums in pots?

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.

Can geraniums be kept in pots during 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.
