Understanding Orchids

Orchids are a diverse and widespread family of flowering plants. They are known for their complex flowers and have a reputation for being exotic and challenging to grow.

History and Origin

The Orchidaceae family is ancient and immensely diverse, originating in the late Cretaceous period. They have evolved over 80 million years, resulting in over 25,000 species. These plants are found on every continent except Antarctica, showcasing their adaptability.

Popular Varieties

1. Phalaenopsis: Commonly known as the “Moth Orchid,” it’s well-regarded for its long-lasting flowers and ease of care.
2. Cattleya: Known for large, fragrant blooms, often referred to as the “Queen of Orchids.”
3. Dendrobium: With thousands of species, this variety is diverse, with some types known for their cane-like stems.

Orchid Biology

Orchids have unique biological features that distinguish them from other plants. They possess mycorrhizal relationships—a symbiotic association with fungi that helps them extract nutrients. Many orchids have a single, central root known as a rhizome, and specialized aerial roots. Their flowers are bilaterally symmetrical and often have a specialized lip called a labellum, which is crucial for pollination.

Getting Started with Orchids

Embarking on the orchid-growing journey is exciting for any beginner. One should focus on understanding the specific needs of orchids, from selecting the right type to ensuring the ideal environment for growth.

Selecting Your First Orchid

When choosing their first orchid, beginners should consider the Phalaenopsis or Moth Orchid. It is known for its resilience and ability to thrive in indoor conditions. They should look for a plant with bright green, healthy leaves and a strong root system.

Essential Supplies

Upon selecting an orchid, the following supplies are necessary:

  • Potting mix: Orchids require a well-draining medium, typically a bark-based blend.
  • Pots: Clear pots with drainage holes are preferred to observe root health.
  • Fertilizer: A balanced, water-soluble fertilizer designed for orchids.
  • Humidity tray: To maintain the moisture level around the plants.

Setting Up Your Space

One must set up a space with indirect sunlight and stable temperatures between 65-80°F (18-27°C) for their orchids. A room with eastern or southern exposure often works best. Humidity levels should remain around 40-70%. A regular watering schedule should be established, paying attention not to overwater the plant.

Orchid Care Basics

Proper care is essential for orchids to flourish. They thrive with the right balance of watering, feeding, and ongoing maintenance.

Watering Techniques

Orchids require precise watering—too much or too little can be detrimental. Moth orchids (Phalaenopsis), for example, should be watered once a week. It’s crucial to let the water drain completely to prevent root rot. A good rule of thumb is to water when the top inch of the potting medium is dry.

Feeding and Fertilization

Fertilizing orchids regularly supports their growth. Use a balanced fertilizer, such as a 20-20-20 blend, once a month during the growing season. During winter, feeding can be reduced to once every other month.

Pruning and Maintenance

To keep orchids healthy, remove any dead or dying flowers and leaves. This encourages the plant to focus energy on new growth. When an orchid flower stalk has finished blooming, pruning it close to the base of the plant can potentially stimulate reblooming.

Troubleshooting Common Issues

Caring for orchids can sometimes be challenging, but recognizing common issues early can help maintain your plant’s health and beauty.

Pests and Diseases

Pests: Orchids may be prone to infestations by spider mites, scale, or mealybugs. One can often spot these pests by examining the underside of the leaves or at the base of the plant. To treat, gently wipe the affected areas with a cotton swab dipped in isopropyl alcohol or use insecticidal soap.

Diseases: Watch for signs of fungal or bacterial infections, indicated by black or brown spots on leaves or a mushy base. Fungal infections can be treated with fungicides, while bacterial infections may require removal of the affected parts and application of a bactericide.

Environmental Stress

Lighting: Orchids exhibit leaf discoloration if the lighting is incorrect; leaves turn yellow from too much light, or dark green if lacking sufficient light. Ensure orchids are placed in bright, indirect sunlight.

Watering: If an orchid’s leaves are wrinkled or limp, this is often a sign of underwatering. Conversely, soft, brown spots may suggest overwatering. Establish a watering routine that allows the orchid’s media to dry slightly between waterings.

Temperature and Humidity: Orchids thrive in environments with 40-70% humidity and temperatures between 60-80°F. Use a hygrometer to monitor levels and avoid placing plants near vents or drafts that can cause stress.

Orchid Rehabilitation

An orchid in poor condition may still recover with proper care. If the roots are brown and soft, this signals root rot. Trim the damaged roots and repot the orchid in fresh, sterile media. If an orchid is dehydrated, immerse the pot in water for 5-10 minutes to rehydrate the roots, then drain thoroughly. Always use pots with drainage holes to prevent water accumulation.

Advanced Orchid Care

Successful cultivation of orchids goes beyond basic care, involving intricate techniques like propagation, the artistry of hybridization, and aesthetically pleasing displays.

Propagation Methods

There are several propagation methods experts may use to increase their orchid collection:

  • Keiki Growth: This is a natural form of asexual reproduction where baby plants, known as ‘keikis,’ form on the mother plant. Applying a keiki paste containing cytokinins can encourage this process.
  • Division: A mature orchid can be divided during repotting. Each division must have at least three pseudobulbs to ensure a viable new plant.
  • Stem Cuttings: Certain orchids allow propagation through stem cuttings. Each section, with one or more nodes, can develop into a new plant under optimal conditions.


Hybridization requires a careful approach to produce new orchid varieties:

  • Cross-Pollination: Orchid enthusiasts select two orchids with desirable traits and transfer pollen from one to the stigma of the other.
  • Seed Flasking: The resulting seeds are typically sterile and require a nutrient-rich agar medium to germinate, in a controlled environment known as flasking.

Orchid Display and Arrangement

Orchid enthusiasts take pride in displaying their plants creatively:

  • Grouping: Orchids can be grouped by color, size, or species for visual impact. It’s vital to consider each orchid’s specific light and space needs.
  • Mounting: Epiphytic orchids can be mounted on natural materials such as wood or cork to replicate their natural growing conditions.
  • Containers: The choice of containers, such as clear pots for root photosynthesis or breathable terracotta, can complement the beauty of the orchids.
