History and Origin

Early Discovery

Geranium were first discovered in the wild regions of South Africa, where they thrived in the warm and sunny climate. European explorers brought these exotic plants back to their home countries in the 17th century, where they quickly gained popularity in gardens and botanical collections. The unique characteristics of geranium, such as their distinctive leaf shapes and vibrant blooms, caught the attention of botanists and gardeners alike.

Native Regions

While geranium are now cultivated worldwide, their native regions include South Africa, Australia, and the eastern Mediterranean. These areas provide the ideal conditions for geranium to flourish, with plenty of sunlight and well-drained soil. Understanding the native habitats of geraniums can help gardeners recreate these conditions in their own gardens, ensuring healthy and thriving plants.

Historical Uses

Historically, geranium have been used for a variety of purposes. In traditional medicine, different parts of the plant were used to treat ailments such as wounds, infections, and digestive issues. The essential oils extracted from geranium were also used in aromatherapy for their calming and anti-inflammatory properties. Additionally, geranium were often grown for their ornamental value, adorning gardens and homes with their colorful and fragrant flowers.


Types of Geraniums

Types of Geraniums

Zonal Geraniums

Zonal geraniums are perhaps the most well-known type of geranium. They are characterized by the distinct dark bands or zones on their leaves, which give them their name. Zonal geraniums produce clusters of single or double flowers in a wide range of colors, including red, pink, white, and orange. They are popular for their robust nature and long blooming season.

Ivy Geraniums

Ivy geraniums have a trailing growth habit, making them ideal for hanging baskets and window boxes. Their leaves resemble those of ivy plants, and their flowers can be single or double, coming in various colors. Ivy geraniums are particularly well-suited to warmer climates, where they can cascade over edges and create a lush, flowering display.

Regal Geraniums

Also known as Martha Washington geraniums, regal geraniums are prized for their large, showy flowers and deeply lobed leaves. They tend to bloom in cooler temperatures and often have a shorter blooming period compared to other types. Regal geraniums come in a variety of striking colors and patterns, making them a favorite for adding dramatic flair to gardens and containers.

Scented Geraniums

Scented geraniums are grown primarily for their fragrant foliage rather than their flowers. The leaves of scented geraniums release a variety of scents, such as rose, lemon, mint, and even chocolate, when touched or crushed. These plants are often used in potpourri, sachets, and essential oils. While their flowers are typically smaller and less showy, the unique scents of scented geraniums make them a delightful addition to any garden.

Climate and Soil Requirements

Geranium are adaptable plants that can thrive in various climates, but they generally prefer warm and sunny conditions. They grow best in well-drained soil with a slightly acidic to neutral pH. Adding organic matter, such as compost, can improve soil structure and fertility, promoting healthy root development. Gardeners in colder regions can grow geranium as annuals or bring them indoors during the winter months.

Planting Techniques

When planting geranium, it’s essential to choose a location that receives at least six hours of sunlight per day. For container planting, use a high-quality potting mix and ensure that pots have drainage holes to prevent waterlogging. Space the plants adequately to allow for proper air circulation, which helps prevent diseases. Planting should ideally be done in the spring after the last frost.

Watering and Feeding

Geranium require regular watering, but it’s crucial not to overwater them, as this can lead to root rot. Allow the soil to dry out slightly between waterings. During the growing season, feeding geraniums with a balanced fertilizer every four to six weeks can promote vigorous growth and abundant blooms. Reduce feeding in the fall to help plants prepare for the dormant period.

Common Problems and Solutions

Geranium can face several common problems, including pests like aphids, spider mites, and whiteflies. Regularly inspecting plants and using insecticidal soap or neem oil can help manage these pests. Fungal diseases such as botrytis blight and rust can also affect geranium, particularly in humid conditions. Ensuring good air circulation, avoiding overhead watering, and using fungicides when necessary can help control these issues.


Caring for Geraniums

Caring for Geraniums

Pruning and Deadheading

Pruning and deadheading are essential practices for maintaining healthy and attractive geranium. Pruning involves removing leggy or overgrown stems to encourage bushier growth and more flowers. Deadheading, or removing spent flowers, helps direct the plant’s energy towards producing new blooms. Regular pruning and deadheading can also prevent the spread of diseases and improve the plant’s overall appearance.

Pest and Disease Management

Effective pest and disease management is crucial for keeping geranium healthy. In addition to using insecticidal soaps and fungicides, practicing good garden hygiene can help prevent issues. This includes cleaning up fallen leaves and debris, rotating plants to different locations each year, and using sterilized tools when pruning. Encouraging beneficial insects, such as ladybugs and lacewings, can also help control pest populations naturally.

Winter Care

In regions with cold winters, geranium need special care to survive the colder months. Gardeners can either treat them as annuals and replant each year or bring them indoors. If bringing indoors, trim the plants back, repot them if necessary, and place them in a sunny window. Water sparingly during the winter, as growth slows down and the plants require less moisture.

Propagation Methods

Geranium can be propagated through seed, stem cuttings, or division. Stem cuttings are the most common method and can be done by cutting a healthy stem, removing the lower leaves, and placing it in water or soil until roots develop. Seeds can be sown indoors in early spring and transplanted outside after the last frost. Division involves separating a mature plant into smaller sections, each with its own root system, and replanting them.

Geranium are versatile plants that can be used in various garden designs. They can create colorful borders, fill in gaps between shrubs, or add interest to rock gardens. Combining different types of geranium with complementary colors and textures can create a visually appealing and dynamic landscape. Using geranium in mass plantings can also create a striking display of color and fragrance.

Container Gardening

Geranium are ideal for container gardening, offering flexibility in placement and design. They can be grown in pots, hanging baskets, and window boxes, making them suitable for patios, balconies, and small spaces. When planting in containers, use a well-draining potting mix and ensure the containers have drainage holes. Grouping containers with geranium and other compatible plants can create attractive and cohesive displays.

Companion Planting

Companion planting involves growing different plants together to benefit each other. Geraniums can be excellent companions for various vegetables and herbs, helping to repel pests and attract beneficial insects. For example, planting geraniums alongside tomatoes can help deter aphids, while pairing them with basil can enhance the growth and flavor of both plants. Experimenting with different combinations can lead to a healthier and more productive garden.
