Orchids: How to Grow and Care with Success

Types of Orchids

There are many different types of orchids, but some of the most popular and widely cultivated include:

Phalaenopsis orchids – also known as moth orchids, these are one of the most popular types of orchids due to their long-lasting blooms and easy care.

Cattleya orchids – known for their large, showy flowers and sweet fragrance, these are often used in corsages and cut flower arrangements.

Dendrobium orchids – these orchids have a wide range of colors and patterns and can produce large sprays of flowers.

Oncidium orchids – commonly referred to as “dancing lady” orchids, these have a distinctive appearance with small, round flowers arranged in clusters.

Vanda orchids – these orchids have striking, colorful blooms and are often grown in hanging baskets to showcase their unique appearance.

Miltoniopsis orchids – also known as “pansy orchids,” these have large, flat flowers that resemble pansies.

Paphiopedilum orchids – known for their distinctive, slipper-shaped blooms, these orchids are often grown for their unique appearance.

How to care for Orchids

While they can be a bit more challenging to care for than other common houseplants, with the right care and attention, orchids can thrive and produce stunning flowers. Here are some details on how to care for them:

Light: Orchids need bright, indirect light to grow and flower. Direct sunlight can burn their leaves, so it’s best to place them near a window with filtered light.

Potting mix: Orchid plants need a well-draining potting mix that allows air to circulate around their roots. You can use a specialized orchid mix or create your own by combining bark, perlite, and sphagnum moss.

Water: Orchids prefer to be watered sparingly but regularly. Wait until the potting mix is almost completely dry before watering, and then water thoroughly until water drains from the bottom of the pot. Avoid getting water on the leaves or in the crown of the plant, as this can lead to rot.

During the warmer months, orchid plants should be watered more frequently, typically once a week. In the colder months, when the orchid is not actively growing, it should be watered less frequently, perhaps every two to three weeks. However, it’s important to always check the moisture level of the potting mix before watering rather than relying solely on a schedule, as the frequency of watering can vary depending on the humidity and temperature of the environment.

Temperature: Most orchids prefer temperatures between 60-85°F during the day and 55-65°F at night. Avoid exposing them to extreme temperatures or drafts.

Humidity: Orchid plants thrive in high humidity, so it’s important to provide them with a humid environment. They require a humidity level of around 40-60%. This can be achieved by placing a tray of water near the orchid or by using a humidifier. It is important not to let the orchid sit in standing water as this can lead to root rot. Regular misting can also help to increase humidity levels around the orchid.

Fertilizer: Orchids benefit from regular feeding with a balanced fertilizer during the growing season. Fertilize them with a balanced, water-soluble fertilizer that is specifically formulated for orchids. Fertilize weekly during the growing season. It is important to dilute the fertilizer to half or quarter strength to avoid over-fertilizing, which can damage the orchid. During the dormant season, they require less fertilizer or no fertilizer at all.

How to Prune Orchids

Pruning and deadheading are important parts of their care routine and can help to promote healthy growth and flowering. Here are some tips:

• Pruning: Remove any dead, damaged, or yellow leaves or stems as soon as you notice them, using a clean and sharp pair of scissors or pruning shears. This will prevent any pests or diseases from spreading to healthy parts of the plant.
• Deadheading: When the flower spike is finished blooming, you can cut it off at the base where it emerges from the foliage. This will help to redirect the plant’s energy towards new growth and flowering. Make sure to use clean, sharp scissors or pruning shears to avoid damaging the plant. Alternatively, you can leave the spike on the plant, but it may become unsightly, and the flowers produced may be smaller. If you choose to leave the spike, cut the stem leaving two nodes on the stem (below where the flowers were). One of these nodes will generally produce flowers within eight to 12 weeks.
• Timing: It’s best to prune and deadhead orchids during the dormant period, which is usually after flowering. Avoid pruning or deadheading during active growth periods, as this can cause stress to the plant.
• Disinfect: Always sterilize your pruning shears or scissors with rubbing alcohol or hydrogen peroxide before and after use. This will help to prevent the spread of any bacteria or fungus.
• Leaves: Avoid cutting the leaves as they are important for photosynthesis and the overall health of the plant. If you do need to trim a leaf, only remove the tip or a small portion of the leaf.

How to Repot Orchids

Repotting orchids is an essential task for their healthy growth. Here are the steps for repotting them:

• Select a new pot: Choose a pot that is one size larger than the current pot. Orchids prefer a snug fit, so don’t choose a pot that is too large.
• Prepare potting mix: Orchids need a well-draining mix that allows air to circulate around the roots. You can use a commercial orchid mix or make your own by combining bark, sphagnum moss, and perlite.
• Remove the plant from its current pot: Be careful not to damage the roots.
• Remove old potting mix: Remove any old potting mix that is still attached to the roots.
• Trim roots: Trim any dead or damaged roots using a sterile pair of scissors.
• Repot: Place the orchid in the new pot and fill in the gaps with the potting mix.
• Water: Water thoroughly and allow it to drain.
• Stake: If your plant is top-heavy, you may need to stake it to provide support.
• Care: Place the orchid in a well-lit area but out of direct sunlight. Water when the potting mix is dry to the touch.

It is recommended to repot orchids every 1-2 years or when the potting mix has broken down, or the roots have outgrown the pot.

How to Get Orchids to Bloom

Some orchids bloom once a year, while others bloom several times a year. It is not uncommon for an orchid to take a break from blooming for a few months before producing new flowers. If an orchid is not blooming, it could be due to several factors, including:

• Lack of proper light: The flowers need the right amount and quality of light to bloom. If they are not getting enough light, they may not bloom.
• Incorrect temperature: Orchids require specific temperature ranges to bloom. If the temperature is too hot or too cold, it can affect blooming.
• Improper watering: Over or under-watering can affect orchid blooming. These plants need to be watered appropriately for their specific type and environment.
• Lack of nutrients: Orchids need the right balance of nutrients to bloom. If they are not getting the right nutrients, they may not bloom.
• Not enough rest time: Orchid plants need a period of rest to bloom properly. If they do not get enough rest, they may not bloom.
• Repotting at the wrong time: Repotting orchids at the wrong time can shock the plant and affect blooming.

Pests and Diseases

Orchids are susceptible to a variety of pests and diseases, including:

Aphids: They can cause damage by sucking the sap from the leaves, causing yellowing and stunted growth. To control aphids, spray the plant with a solution of water and mild soap or neem oil, making sure to cover the undersides of the leaves where aphids tend to congregate.

Mealybugs: White, cotton-like insects that cluster at the base of leaves or along the stem. They can be removed with rubbing alcohol.

Scale: Small, hard, and waxy bumps on the leaves or stems. These can be removed with rubbing alcohol.

Spider mites: Tiny insects that spin webs on the leaves. They can be treated with insecticidal soap.

Fungal and bacterial diseases: Symptoms include spots on leaves, wilting, and rotting. Prevent these by avoiding over-watering and providing proper air circulation.

Regular inspection of the orchids can help catch pest and disease problems early, allowing for effective treatment and prevention of further spread.
