Choosing the Right Geranium

When selecting geraniums, look for healthy, robust plants. The variety you choose, whether it’s the popular zonal geraniums known for their colorful leaf zones or the trailing ivy-leafed geraniums, will dictate your care approach.

Planting Geraniums

The best way to start is with transplants, readily available in garden centers. Plant them in spring, post the last frost, spacing them about 8 to 12 inches apart. Mulching is recommended to retain moisture.

Geranium Light Requirements

Geraniums flourish in full sun but can tolerate partial shade. Aim for 4 to 8 hours of direct sunlight daily. If you’re growing them indoors, ensure they receive ample light for blooming.

Watering Needs

Water your geraniums when the top inch of soil feels dry. They prefer dry soil over wet, so avoid overwatering. In hot weather, outdoor potted plants may need daily watering.

Soil and Fertilization

Geraniums thrive in well-draining soil. A mix of indoor potting soil, peat, and perlite works wonders. Fertilize every four to six weeks during the growing season with a balanced fertilizer.

Pruning and Maintenance

Geraniums require minimal maintenance. Regular deadheading keeps them blooming, and occasional pruning encourages branching. Avoid overwatering to prevent rot and mold, especially in humid conditions.

Common Pests and Diseases

Watch out for aphids, whiteflies, and mites. Maintain good airflow around the plants and keep the foliage dry to prevent infestations.
Geranium Propagation

From Cuttings

Cuttings are the easiest way to propagate geraniums. In warm climates, take cuttings in early summer. In cooler areas, do this in late summer or early fall and root them indoors for spring.

From Seed

Geraniums can also be grown from seed, but they mature slowly. Start them 8 to 10 weeks before the last frost date.

Overwintering Geraniums

To save your geraniums for the next season, overwinter them by taking cuttings or bringing them indoors before the first frost. Reduce watering and place them in a cool spot with bright light.

Types of Geraniums

  • Zonal Geraniums: Known for their leaf color zones and vibrant flowers.
  • Ivy-leafed Geraniums: Characterized by their trailing growth and ivy-like leaves.
  • Scented-leaf Geraniums: Offer a variety of fragrances like rose, apple, and peppermint.
  • Regal Geraniums: Often used as houseplants due to their showy flowers.
