Purple orchids are among the most striking flowers you can add to your home or garden. Their vibrant hues and elegant petals make them a favourite among plant enthusiasts, but caring for these beautiful plants isn’t always straightforward. Many people, especially those new to orchid care, encounter a variety of challenges that can lead to unhealthy plants or even loss of blooms. To help you succeed, we’ll delve into the top 10 mistakes and problems associated with purple orchids and provide easy solutions to keep them flourishing.

1. Overwatering

Problem: One of the most common mistakes made by orchid owners is overwatering. While it might seem like more water would help your orchid thrive, these plants are actually quite sensitive to excessive moisture. When purple orchids are overwatered, their roots can become waterlogged, leading to root rot—a condition where the roots turn black and mushy, eventually killing the plant. This often happens because the orchid is left sitting in water or the potting medium retains too much moisture.

Solution: The key to preventing overwatering is to water your orchid only when necessary. A good practice is to check the potting medium before each watering. Insert your finger about an inch into the medium—if it feels dry, it’s time to water. Ensure your orchid pot has adequate drainage, allowing excess water to escape. Orchids generally need watering once a week, but this can vary based on factors like climate, season, and the specific type of orchid. After watering, make sure the plant isn’t sitting in water by emptying any excess from the saucer.

2. Underwatering

Problem: While overwatering is a common issue, underwatering can be equally detrimental to your purple orchid’s health. Orchids that don’t receive enough water will develop dry, shrivelled roots, and their leaves may become limp and wrinkled. This often occurs when owners are too cautious about overwatering or when they simply forget to water the plant regularly.

Solution: To avoid underwatering, establish a consistent watering routine. Monitor the moisture levels of the potting medium on a regular basis.

If you notice the roots appearing white or grey and the leaves showing signs of dehydration, it’s a clear indication that your orchid needs water. When watering, it’s beneficial to give the orchid a thorough soak, allowing water to penetrate the potting medium and reach the roots. Let the plant sit in the water for about 10 minutes, then ensure it drains completely before returning it to its usual spot.

3. Improper Light Exposure

Problem: Light is crucial for orchid health, but finding the right balance can be tricky. Orchids require a certain amount of light to photosynthesise and produce the energy needed for growth and flowering. However, too much direct sunlight can scorch the leaves, leading to unsightly burn marks, while too little light will prevent the orchid from blooming and cause the leaves to darken.

Solution: Purple orchids thrive in bright, indirect light. An east-facing window is often the best spot, as it provides the morning sun’s gentle rays without the intense heat of the afternoon. If you notice your orchid’s leaves turning dark green, it might be an indication that the plant isn’t getting enough light. Conversely, yellowing leaves could signal too much direct sunlight. Adjust the orchid’s placement accordingly, and consider using sheer curtains to diffuse harsh sunlight.

4. Wrong Potting Mix

Problem: Using the wrong potting mix is a common mistake that can severely affect your orchid’s health. Unlike other houseplants, orchids do not grow well in standard potting soil. Regular soil tends to retain too much moisture and compacts easily, suffocating the orchid’s roots and leading to root rot.

Solution: Orchids require a potting mix that allows their roots to breathe and drain well. The ideal mix usually contains materials like bark, sphagnum moss, or a special orchid mix available at garden centers. These materials achieve the ideal mix of moisture retention and aeration.

When repotting your orchid, make sure to choose a mix that’s specifically designed for orchids, which will help mimic their natural growing conditions.

5. Inadequate Humidity

Problem: Purple orchids originate from tropical environments where humidity levels are naturally high. Inadequate humidity in your home can lead to various problems, including bud drop—where the buds fall off before they bloom—and wrinkled, unhealthy-looking leaves.

Solution: To replicate the orchid’s natural environment, it’s important to maintain a humid atmosphere around the plant. You can increase humidity by placing your orchid on a humidity tray filled with water and pebbles, ensuring the bottom of the pot is not submerged. Misting the orchid daily can also help, but avoid misting late in the day to prevent water from sitting on the leaves overnight. Alternatively, a room humidifier can effectively raise the humidity level in the area where your orchid is kept. Grouping orchids can also generate a microclimate with increased humidity levels.

6. Neglecting fertilisation

Problem: Orchids, like all plants, need nutrients to grow and produce flowers. However, many orchid owners either forget to fertilise or are unsure how to do it properly. Without regular feeding, your purple orchid might struggle to grow and may fail to bloom altogether.

Solution: Fertilising your orchid is essential for its overall health and blooming potential. Use a balanced, water-soluble fertiliser designed for orchids, and apply it every two weeks during the growing season, which is typically spring and summer. In the fall and winter, when the orchid’s growth slows down, you can reduce fertilisation to once a month. Always follow the instructions on the fertiliser package, and be careful not to over-fertilise, as this can damage the roots.

7. Not Pruning Dead Blooms

Problem: Once your orchid’s blooms have faded, it’s important to prune them properly. Failing to remove dead flowers can cause the plant to waste energy on maintaining the old spike, which can hinder new growth and future blooms.

Solution: After your orchid finishes blooming, use a sterilised pair of scissors or pruning shears to trim the flower spike just above a node (the small bump on the spike). This can encourage the orchid to produce new blooms on the same spike. If the spike turns brown and dries up completely, it’s best to cut it back to the base. Pruning on a regular basis allows the plant to preserve energy and focus it towards the production of new leaves, roots, and flowers.

8. Temperature fluctuations

Problem: Orchids are sensitive to changes in temperature, and sudden fluctuations can stress the plant. This stress can lead to issues like bud blast, where the buds drop off before opening, or slow growth during the blooming season.

Solution: To keep your purple orchid healthy, maintain a stable temperature in the room where it’s kept. Orchids generally prefer temperatures between 65-75°F (18-24°C) during the day, with a slight drop at night. Avoid placing your orchid near draughty windows, air conditioners, or heaters, as these can cause sudden temperature changes. Consistency is key—by keeping the temperature steady, you’ll help your orchid thrive.

9. Pests and Diseases

Problem: Orchids can fall victim to a variety of pests and diseases, including aphids, mealybugs, spider mites, and fungal or bacterial infections. These issues can cause significant damage if not addressed promptly, leading to weakened plants and poor blooming.

Solution: Inspect your orchid on a regular basis for pests and diseases.

If you spot pests like aphids or mealybugs, treat them with insecticidal soap or neem oil, applying it according to the instructions. For spider mites, a thorough rinse with water can help dissolve them. Fungal and bacterial infections often manifest as black spots, wilting leaves, or soft, mushy areas on the plant. Remove any affected parts with sterilised tools and apply a fungicide if necessary. Keeping your orchid’s environment clean and well-ventilated can help prevent these problems from occurring in the first place.

10. Not Repotting Regularly

Problem: Over time, orchids outgrow their pots, and the potting mix begins to break down, leading to poor drainage and root rot. If you don’t repot your orchid regularly, the roots can become overcrowded and unhealthy.

Solution: Repot your purple orchid every 1-2 years to provide it with fresh growing conditions. The best time to repot is after the orchid has finished blooming and before new growth begins. Choose a pot that’s slightly larger than the current one, and use a fresh orchid-specific potting mix to ensure good drainage and aeration. Repotting not only gives the roots more room to grow but also prevents the buildup of salts and other residues in the old potting medium that can harm the plant.

Successfully growing and caring for purple orchids requires attention to detail and a willingness to learn from mistakes. By understanding and avoiding these common pitfalls, you can ensure that your orchid thrives, producing beautiful blooms year after year. Remember, orchids are resilient and adaptable, so with the right care, even beginners can enjoy the rewards of these stunning plants. Whether you’re new to orchid care or an experienced grower, following these tips will help you maintain a healthy, vibrant purple orchid that brightens up your space.
