Orchids are renowned for their intricate, long-lasting blooms and come in a wide array of varieties with different sizes, colors, and aromas. They can thrive in various growing conditions, ranging from low-light indoor areas to tropical outdoor habitats. While some orchids are easy to care for, others may require more attention and effort to maintain. If you find the perfect orchid for your home or garden, you might want to consider propagating more plants.
We spoke with orchid experts who shared three essential propagation methods and some best practices for nurturing these beautiful plants. Meet the Experts:
– Tammy Sons, founder and CEO of TN Nursery
– Matt Ramos, owner of Plant Sensation & Co.
Propagation From Division:
Dividing an orchid involves separating the plant into smaller sections, each with its own growth points and roots. According to Tammy Sons, it’s best to choose a mature plant with established growths for division. Use sterile tools like pruning shears, a knife, or scissors to prevent disease. Remove old soil from the roots when repotting the plant and identify sections with roots, eyes, or leaves. Some species may have pseudobulbs, which store nutrients. Each division should ideally have at least three pseudobulbs. Carefully separate each section with sterilized tools and repot them individually using fresh orchid medium such as sphagnum moss or bark. Newly divided plants require light watering and should be placed in a humid and bright area, away from direct sunlight.
Propagation From Cuttings:
While division is the traditional method for orchid propagation, some species like Dendrobium can be propagated from cuttings. Matt Ramos recommends selecting a stem with a healthy node, cutting it just below the node with sharp scissors, and planting it in an orchid mix, ensuring the node is slightly buried. Keep the cutting in a warm, humid place with indirect light until roots form, which may take a few weeks.
Propagation From Seed:
Propagating orchids from seeds is a more complex process, as orchid seeds lack stored nutrients and rely on fungi for germination. Collect seeds from a mature orchid pod and sterilize them by soaking in a mild bleach solution. Use a clean container or petri dish with a specialized orchid seed mixture or agar-based medium. Sprinkle the seeds onto the surface and follow specific instructions for germination.
Overall, propagating orchids requires careful attention and proper techniques to ensure successful growth and blooming.
“Ensure that the seeds are evenly distributed, not buried, to allow for adequate light for germination,” advises expert Sons. “Maintain the container in a warm and humid environment with temperatures ranging between 70 to 75 degrees Fahrenheit. It may take several months for the seeds to germinate and develop further,” she adds. “Once the plants mature, they can be transferred to individual pots.”
When caring for propagated orchids, Sons recommends transplanting them into small pots with well-draining orchid mix once they have developed roots and leaves. Adequate sunlight is essential for their growth, but direct sunlight should be avoided as it may damage the plants. Sons suggests providing indirect sunlight and maintaining humidity levels between 50 to 70 percent.
To ensure the right humidity levels, Sons recommends using a humidity tray or misting the plants regularly. Placing the orchids in a naturally humid environment, such as a bathroom, can also help retain moisture. Orchids thrive in warmer temperatures, so it is important to avoid exposing them to fluctuating temperatures near sources like air conditioners or heaters.
Proper watering is crucial for the health of propagated orchids. Sons advises keeping the orchids moist but not overwatered, as excess water can cause root rot and insufficient watering can lead to stunted growth. Allowing the potting medium to slightly dry out between waterings and using lukewarm water is recommended.
When it comes to fertilizing propagated orchids, Sons suggests using a diluted and balanced orchid fertilizer once the plants begin to establish roots or show new growth. This should be applied monthly or as per the instructions on the fertilizer packaging. When repotting orchids, make sure to place them in a larger container with fresh, well-draining orchid mix.
