How To Grow Orchid: Potting and Blooming

The best time to plant orchids depends on the type of orchid and your local climate. However, most orchids are not planted in the traditional sense as they are typically grown in pots with special orchid medium rather than in the ground.

Here are some general guidelines:

• Indoors: Orchids can be started indoors at any time of the year if you can control their environment, especially temperature and humidity. The key is to mimic the natural conditions of your specific orchid species as closely as possible.

• Outdoors: If you live in a climate similar to the orchid's natural habitat, you can move them outdoors or plant them when temperatures are suitable for the specific type of orchid. This is usually done after the danger of frost has passed in spring and when temperatures do not drop below the orchid’s tolerance at night.

• Seasonal Growth Cycles: Many orchids have a specific growth cycle, with a period of active growth followed by a period of dormancy. It's best to repot or divide orchids during their dormant phase, which often falls after they bloom. This timing can vary widely among orchid species.

• Specific Orchid Types: Phalaenopsis orchids (often called moth orchids) can be bought and started indoors at any time of the year. This variety tends to flower regardless of the season, as long as its environmental needs are met.

Growing orchids can seem daunting due to their exotic appearance, but many types are quite forgiving and can thrive with the right orchid care. Here's how to grow orchids in seven basic steps.

Focus on the commonly available types, such as Phalaenopsis (moth orchids), which are a good starting point for beginners.

1. Choose the Right Orchid

Start with a beginner-friendly orchid, like a Phalaenopsis, which is adaptable to indoor conditions. Look for an orchid with bright, firm leaves and, if possible, roots that are green or white and appear healthy.

2. Use the Proper Potting Medium

Orchids generally don't grow in regular potting soil but in a special orchid mix designed to drain quickly and provide air to the roots. This mix often contains bark, sphagnum moss, and perlite.

3. Select an Appropriate Pot

Use a pot with good drainage to prevent water from pooling at the bottom, which can cause root rot. Many orchids benefit from clear pots that allow light to reach the roots.

4. Provide Adequate Light

Most orchids thrive in bright, indirect light. A window facing east or west is often ideal. Direct sunlight can burn the leaves, while too little light can prevent flowering.

5. Water Properly

Overwatering is a common mistake. Water your orchid only when the potting mix has dried out, usually every 5 to 7 days, depending on conditions like humidity and temperature.

Water thoroughly, allowing water to run freely through the potting mix and out the drainage holes.

6. Maintain Humidity and Temperature

Orchids enjoy a humidity level of about 40-70%. Use a humidity tray or a room humidifier if your home is dry.

Moreover, keep temperatures between 60-75°F (15-24°C) during the day and slightly cooler at night, which many orchids prefer.

7. Fertilize Regularly

Use a balanced, water-soluble fertilizer diluted to half-strength, typically every other week during the growing season. In the dormant season, reduce fertilization.

Potting and repotting orchids are crucial aspects of their care, helping to ensure they have the appropriate environment to thrive, grow, and bloom.

Orchids require a different approach compared to most houseplants due to their unique root systems and growth patterns. Here's how to pot and repot orchids effectively:

When to Repot

• Repot orchids every 2-3 years, or when the potting medium has broken down and no longer drains well. After blooming is an ideal time, as the orchid is entering a new growth cycle.
• Other signs that an orchid needs repotting include roots growing over the edge of the pot, through drainage holes, or if the plant is unstable in its pot.

Choosing the Right Potting Medium

• Select a potting mix designed for orchids. These mixes often include bark, perlite, and sphagnum moss, providing the drainage and aeration orchid roots need.
• The choice of medium can depend on the orchid type. For example, Phalaenopsis orchids generally do well in a bark mix, while some other species might prefer more moss.

Selecting a Pot

• Plastic pots are lightweight and retain moisture longer, while clay or terracotta pots offer better air circulation and dry out more quickly.
• Choose a pot that is just large enough to accommodate the root system. Orchids prefer snug quarters, and a too-large pot can lead to moisture-related issues.
• Ensure the pot has adequate drainage holes. Clear pots are beneficial for orchids, allowing light to reach the roots and letting you see when to water.

Potting and Repotting Steps

• Gently take the orchid out of its current pot. If the roots stick, you might need to cut the pot away.
• Remove any dead or rotting roots with sterilized scissors or pruners. Healthy orchid roots are firm and green or white.
• Place a layer of orchid potting mix at the bottom of the new pot.
• Set the orchid in the pot so that the base of the plant (where the roots emerge) is just below the rim. This placement ensures that the plant isn't too deep in the medium.
• Gently fill around the roots with the orchid potting mix, tapping the pot to settle the mix without compacting it too tightly.
• Water the orchid thoroughly after repotting to help settle the potting mix around the roots. Then, allow the pot to drain completely.

Aftercare

• Avoid fertilizing for about a month to let the plant recover and adjust to its new pot without burning the roots.
• Keep an eye on the plant for signs of stress and adjust care as needed. It's normal for the orchid to take some time to acclimate to its new pot.

Orchid propagation is a rewarding process for enthusiasts looking to expand their collection or share plants with friends. While orchids can sometimes be more challenging to propagate than other plants, with patience and the right technique, it's certainly achievable. Here are the most common methods for propagating orchids:

1. Division

Division is a straightforward method for propagating sympodial orchids during repotting, ideally in spring when new growth appears. Carefully extract the orchid from its pot, removing the old potting medium. Identify natural divisions, ensuring each section has at least three pseudobulbs.

Use a clean knife to cut through the rhizome, separating divisions, and individually pot them in a suitable orchid mix. This method promotes healthy growth and can be effective in expanding your orchid collection.

2. Keiki (Baby Plant) Propagation

Keiki propagation is a method for reproducing Phalaenopsis orchids. Once a keiki (baby plant) on the flower spike develops several roots, usually a couple of inches long, it is ready for separation. Using a sterilized blade, carefully cut the keiki along with a portion of the attached spike from the mother plant.

Plant it in a small container with orchid potting mix, ensuring roots are buried and leaves remain above the surface for successful growth.

3. Back Bulb Propagation

Back bulb propagation is a technique for rejuvenating or establishing sympodial orchids. Ideally performed during repotting or when back bulbs are accessible, choose those with one or two dormant eyes.

These eyes indicate potential growth points. Pot the back bulb in damp sphagnum moss or a fine orchid bark mix, maintaining high humidity. With patience, a new shoot will emerge, allowing for the revival or initiation of a healthy orchid plant.

4. Seed Propagation

Orchid seed propagation is intricate and generally not recommended for casual home growers due to the minuscule size of orchid seeds and their reliance on a symbiotic fungus for germination.

The process involves sterile lab conditions, with seeds sown in flasks under controlled, sterile environments on a nutrient agar medium. While fascinating, successful orchid seed germination demands specialized equipment and knowledge, making it a technique better suited for experienced orchid enthusiasts or professionals in dedicated facilities.

Orchid bloom times vary by species, with some flowering in winter and others in summer. A typical orchid may bloom once a year, and the flowers can last from a few weeks to several months, depending on the orchid type, environmental conditions, and care provided to the plant.

Appearance and Fragrance While Orchid Blooms

Orchid blooms exhibit a stunning array of colors, shapes, and sizes, captivating with their exquisite beauty. Their diverse appearances range from intricate patterns and vibrant hues to elegant, waxy textures. Orchids often boast symmetrical, three-petaled structures, with a unique lip or labellum, serving as a focal point for pollinators.

While some emit a mild, pleasant fragrance that varies between species, not all orchids are fragrant. Fragrance intensity can differ, with some varieties producing a subtle, sweet scent, enhancing the overall allure of these enchanting flowers during their blooming period.

Bloom Care

After an orchid has finished blooming, proper care is crucial to encourage reblooming. For Phalaenopsis orchids, you can cut the flower spike above the node where the first flower bloomed to potentially encourage a secondary spike.

Continue caring for your orchid with proper light, watering, and temperature conditions to support its overall health and set the stage for the next blooming cycle.

Orchids comprise a vast and diverse family with numerous types, each showcasing unique characteristics. Here are some popular types of orchid plants:
