When To Plant Perennial Geraniums

In order to give the plant enough time to establish its roots before a frost, divide the geraniums in the early spring to early summer.

where to grow geraniums

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.

How are perennial geraniums planted?

There is no “one size fits all” care for geraniums because there are so many different kinds available in the trade. Perennial geraniums are fortunate to be hardy and versatile. Geraniums may thrive anywhere from full sun to partial shade. Many cultivars can also thrive in greater shade, though they can produce fewer flowers. Additionally, perennial geraniums enjoy well-drained soil and may complain if it is too damp.

Geraniums benefit from having their stems cut back once they’ve finished blooming. Those plants that bloom on longer stems can be pruned back to their basal foliage development. This will prevent them from looking too disorganized and encouraging fresh development. On some species, it could also give you a scattering of rebloom.

Do geraniums grow year-round?

Geraniums actually belong to two different botanical subgroups. The perennial varieties are the real geraniums. The geraniums that most people envision when they go plant shopping are the annual bedding varieties with flowers that resemble lollipops and are mounted on stick stems. The plant genus Pelargonium includes several bedding plants. Ivy geraniums, aromatic geraniums, and Martha Washington geraniums are just a few of the numerous additional geraniums that belong in the Pelargonium genus.

Hardy geraniums should be planted when?

Among the most common garden perennials are hardy geraniums, sometimes known as cranesbills. And it’s clear why. They require little care and maintenance, are hardy, easy to grow, and tolerant of a variety of environmental factors.

The bloom color ranges from vibrant to subdued violet, blue, pink, magenta, and white hues, and many have appealing veining in a stronger, contrasting hue. Throughout the summer and well into autumn, several types flower nonstop for months at a time, and some even begin blooming as early as late April. When in bloom, the flowers, which are typically rather small, are produced in such great quantities that they almost completely cover the plants.

Numerous species’ hand-like foliage, which exhibits varied quilting, veining, and color blotching, is also very appealing in and of itself. Additionally, because many of the popularly cultivated kinds are low-growing, they make wonderful ground cover plants due to their dense, carpet-like leaf.

They should not be mistaken with the very similarly related pelargoniums, which aren’t and are primarily used as summer bedding plants, as they are cold- and frost-hardy.

Cultivation

There are kinds that can thrive in direct sunlight, light shade, and even pretty deep shadow. They generally thrive in early morning and late afternoon sun, while some, like Geranium sanguineum and Geranium pratense and their variants, grow well in full light as long as the soil has enough moisture.

Hardy geranium varieties

There is at least one hardy geranium for every garden, every gardener, and every circumstance as there are about 70 species and 700 types to choose from!

Here are the top 10 items that the Royal Horticultural Society suggests:

  • Ann Folkard, geranium
  • (Cinereum Group) Ballerina named Geranium
  • Clarkei Kashmir White Geranium
  • Red geraniums
  • Theodora Mavis Simpson
  • Ingersoll Orion
  • The Mrs. Kendall Clark geranium
  • Wageningen’s Geranium x oxonianum
  • Renardii geranium
  • Jolly Bee and Geranium Rozanne (Gerwat)

Planting hardy geraniums

Hardy geraniums can be planted at any time of year, but planting in the fall or winter will ensure that the plants take root effectively and provide an abundance of flowers in their first season. For planting from late autumn to late winter, mail-order vendors often offer bare-rooted plants.

Make a hole that is sufficiently large to readily fit the rootball. Fork in a layer of organic material, such as compost or planting compost, at the bottom of the hole.

Place the rootball in the planting hole, adjusting the planting depth until the rootball’s top is level with the soil and the rootball is planted at the same depth as it was growing initially.

Fill the planting hole with the excavated soil after adding more organic matter to it. To maintain soil moisture and aid in weed control, thoroughly water the area around the tree, then sprinkle a granular general feed over the surrounding soil. Finally, put a 5-7.5cm (2-3in) deep mulch of well-rotted garden compost or bark chips around the tree’s root area.

How to care for hardy geraniums

The majority of hardy geraniums are undemanding, low-maintenance plants.

When the weather is dry during the first year, water thoroughly. To maintain healthy plant growth in succeeding years, watering may be required during extended dry spells.

Late spring mulching around the plants will assist retain soil moisture and control weed growth.

Plants may start to seem messy with sloppy growth after the first early flush of blossoms has faded. After the initial flowering, the majority benefit from a trim to freshen the foliage and promote more blooms. To get rid of the outdated, messy growth, just cut the plants with a pair of shears or secateurs, or more forcefully if necessary, to a height of 5-7.5cm (2-3in) above the ground.

Then feed them with a liquid plant food to promote new growth and additional flowering flushes. After each flowering, pruning and fertilizing can be done again to extend the flowering season of many kinds well into the fall.

With the arrival of colder weather in late autumn, most geraniums’ foliage will start to fade. If you trim the plants’ leftover stems and leaves, they’ll grow new, fresh growth the following spring.

Over time, hardy geranium plants expand, spread, and form enormous clumps. These can be chopped into halves or quarters with a sharp spade. This can be done in the spring when they begin to grow or in the autumn. Every three to five years, divide them to maintain good growth and flowering.

Can geraniums survive the cold outside?

Knowing how to overwinter geraniums is very useful for gardeners since it can help them save money and extend the life of particular varieties they enjoy.

Pelargoniums, sometimes known as geraniums, are mainstays of the summer garden. Geraniums are ideal for adding cheer and long-lasting color to hanging baskets, containers, and borders since they come in a variety of colors and flower continually as long as they are deadheaded.

However, when making your job list, you might consider including them as one of your winter garden ideas.

When growing frost-sensitive plants, planning a winter garden is crucial. Geraniums are perennial plants that put on a long display, but they are frost tender, which means they won’t survive harsh winters. If you are interested in cultivating geraniums, you must learn how to overwinter them.

Geraniums are South African natives that thrive in the heat and can withstand periods of drought with little water.

Pelargoniums, sometimes known as geraniums, may live in USDA zones 7 to temperatures of -12oF (0oC) if they are sheltered. They are hardy in climates between 20oF and 50oF in zones 9 through 12. They need to be sheltered in these conditions because, while they can withstand brief frosts (temperatures slightly below freezing), they cannot withstand prolonged exposure.

The Pelargonium genus contains a wide range of cultivars, all of which are categorized as delicate perennials. According to David Taylor, vice chairman of the UK Pelargonium and Geranium Society, “this means that they are not cold hardy as the majority of the founding species come from the warmer climbs of the Southern Hemisphere.

Perennial plants are able to flourish for a number of years, however in the UK this would mean that they would also need to be sheltered from winter wet and damp in addition to frost.

Geraniums can be cared for like annuals by being dug out in the fall, composted, and then replaced with fresh plants the following year. The appropriate care and attention, however, will enable you to winterize geraniums, keeping them alive throughout the winter so they can bloom once more the following year.

According to David Taylor, vice chairman of the UK Pelargonium and Geranium Society, “Keen enthusiasts keep their pelargoniums in growth during the winter and continue to feed and water but a few key points can be undertaken by anyone to keep your pelargoniums (geraniums) alive throughout the winter” (opens in new tab).

Pelargoniums are known as geraniums, but these plants are not the same as hardy geraniums or cranesbill, which are a different kind of plant and don’t need to be overwintered.

Perennial geraniums live how long?

You may divide geraniums into two primary groups. There are real geraniums, also known as cranesbill and hardy geraniums. They are frequently mistaken for common or scented geraniums, which belong to the related but distinct genus Pelargoniums. Compared to true geraniums, these offer a considerably more impressive flower display, but they are more difficult to maintain over the winter.

Only USDA zones 10 and 11 are suitable for growing pelargoniums, which are native to South Africa. They are typically only grown as annuals in most countries, despite the fact that they can live for many years in warm regions. They may also be raised in containers and brought indoors to overwinter. As long as it doesn’t get too cold, the common geranium can live for many years.

On the other hand, true geraniums can be cultivated as perennials in a considerably wider range of conditions because they are far more cold hardy. For the most part, USDA zones 5 through 8 are winter-hardy. Some types can withstand the hotter summers in zone 9, while others can endure winters that are as chilly as those in zone 3, at least for the roots.

As long as it is properly cared for, geraniums can live for many years. Additionally, they are easily overwintered. Some other kinds, like the biennial Geranium maderense, only live for two years but can withstand most winters.

In order to answer the question “how long do geraniums live,” it is important to consider both your location and the sort of geranium plant you own.

Is it necessary to trim perennial geraniums in the fall?

You should prune a perennial geranium after it has bloomed all season and starts to wither. This helps the plant store energy for the spring while simultaneously keeping it dormant for the winter. This could need to happen any time between August and late October, depending on your zone. Cut perennial geraniums down to 2 or 3 inches above the soil with a pair of trustworthy shears, ideally at nodes or new growth points. Take out any more flowers or foliage. You’ll have a collection of thick stems that is really ugly. But don’t panic, your blooms will return in full bloom the following spring.

What is the lifespan of perennial geraniums?

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.

How do you maintain the flowering of perennial geraniums?

How to Increase Hardy Geranium Blooms

  • Give the Right Lighting. Make sure your blooms are receiving enough sunlight.
  • Maintain Soil Moistness. Keep the soil damp but not soggy.
  • Detach any leggy growth. Midsummer is the time to prune the plants.
  • Give Your Plants Food. To promote blooming, apply a fertilizer strong in potash.

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.
