Growing Conditions

Creating an optimal environment for perennial geraniums is crucial to ensure their health,

longevity, and prolific blooming.

These plants, with their diverse varieties, are generally adaptable, but certain growing conditions

enhance their overall performance.

Here are key factors to consider:


Perennial geraniums thrive in partial to full sunlight.

Provide at least 4-6 hours of direct sunlight daily for optimal flowering.

In warmer climates, some varieties appreciate partial shade during the hottest part of the day.


Choose well-draining soil to prevent waterlogging, as geraniums are susceptible to root rot.

A slightly acidic to neutral pH (around 6.0 to 7.5) is ideal for most varieties.

Incorporate organic matter into the soil to improve its fertility and texture.


Keep the soil consistently moist but not waterlogged.

Water deeply, allowing the soil to dry slightly between watering sessions.

Watering in the morning helps prevent fungal diseases by allowing foliage to dry before evening.


Perennial geraniums are generally hardy and can tolerate a range of temperatures.

Most varieties are well-suited for USDA Hardiness Zones 4-8, but this can vary by


Protect plants from extreme heat or cold, especially during their establishment period.


Space plants according to their mature size, ensure adequate air circulation.

Plant at the same depth as they were in their nursery containers.

Mulch around the base to conserve moisture, suppress weeds, and regulate soil temperature.

Adhering to these growing conditions sets the stage for healthy and vigorous perennial geraniums.

Regular monitoring of the soil moisture, adapting watering schedules to local climate conditions,

Trim spent flowers regularly to encourage continuous blooming.

Cut back the entire plant by one-third to one-half in midsummer to promote a fresh flush of growth

and blooms.

Remove any dead or yellowing leaves to maintain a neat appearance.


Apply a balanced, slow-release fertilizer in the spring as new growth emerges.

Avoid over-fertilizing, as excessive nutrients can lead to leggy growth and reduced


Monitor the plant’s response to fertilization and adjust accordingly.


Apply a layer of organic mulch, such as compost or bark, around the base of the


Mulching helps retain soil moisture, suppress weeds, and regulate soil temperature.

Refresh the mulch layer as needed, particularly in the spring.


Divide overcrowded clumps every three to four years to rejuvenate the plants.

Lift the entire clump, divide it into smaller sections, and replant the divisions.

The division promotes better airflow, prevents overcrowding, and stimulates healthier growth.

Pests and Diseases:

Monitor for common pests such as aphids, caterpillars, and spider mites.

Treat pest infestations promptly using insecticidal soap or neem oil.

Perennial geraniums are generally resistant to diseases but remove any diseased foliage promptly

to prevent spread.

Winter Care:

Frequently Asked Questions

Do perennial geraniums like sun or shade?

Perennial geraniums typically do not demand fertilizer unless the soil is deficient.

Nevertheless, they benefit from an annual application of a well-balanced granular formulation,

like a 10-10-10 product, administered in early spring before the plant begins blooming.

Alternatively, a 2-inch layer of compost serves as a suitable substitute for a

commercially purchased fertilizer.

Can perennial geraniums grow in pots?

Indeed, placing perennial geraniums in pots might yield better results in warmer

regions like the Mid and Lower South.

This is attributed to the fact that maintaining them in containers exposes the root zone to the

essential winter chill hours required for optimal performance.

Do geraniums like eggshells?

The majority of flowers and many succulents can reap the advantages of eggshells,

but it’s crucial not to overwater the succulents.

Curious about which plants aren’t fond of eggshells? It’s advisable to refrain from using them on

species that naturally thrive in more acidic soil, such as azaleas and geraniums.

Geraniums are susceptible to insect attacks from pests such as aphids, cabbage loopers, and fall


Damage can also be caused by the four-lined plant bug, scale, and slugs.

It is essential to accurately identify the specific insect pest and employ the recommended

insecticide for effective control.

Despite these potential challenges, geraniums remain one of the most favored annual plants

among gardeners today.
