Propagation of Sedopsis sedoides
Sedopsis sedoides or popularly known as Wax Stem Orchid is a tropical plant with interesting characteristics that make it highly infatuating to gardeners. For those who would like to propagate Sedopsis sedoides plant, Here are effective methods to propagate the plant:
Propagation by Division
Division is the most common and easiest method of Sedopsis sedoides propagation. The best time to propagate is when you see new growth, generally during spring or early summer. Here's how to do it:
- Carefully remove the plant from its container or garden bed and clean off any debris attached to the roots.
- Inspect for natural separations and pull them apart gently. Divide the plant into two or more sections, ensuring that each section has its own roots, stem, and leaves.
- Plant the divided sections of the plant into the new soil, water thoroughly, and provide the right environmental conditions for the new plants to thrive.
Propagation by Orchid Cuttings
Another way to propagate Sedopsis sedoides is through stem cuttings. Try to take cuttings when the plant is just starting to grow in the spring or early summer. Here's how to propagate using stem cuttings:
- Using a sharp and clean pair of scissors, cut a 4-inch section of the stem from the mother plant.
- Place the stem cutting in a sterilized pot filled with moistened potting soil. Firm the soil around the stem to keep it in an upright position.
- Place the pot in a warm, humid location with indirect sunlight. Keep the soil moist, but not soggy until the cutting establishes roots and shows new growth.
- Once the cutting starts growing, transplant the young plant to a larger container or outdoor garden.
Propagation by Seed
Propagating Sedopsis sedoides via seeds is possible but can be challenging due to low fertility rates. If you wish to take on this method, follow these steps:
- Collect the fresh seeds and soak them in water for 24 hours before you sow them.
- Prepare a container or garden bed and add the seed-starting potting mix. Make sure the soil is sterile and well-draining.
- Sow the seeds directly on the surface of the soil, and press them gently into the soil without covering them. Spray the soil with water gently.
- Place the container or the bed in a warm, humid location with indirect light.
- Keep the soil moist but not waterlogged until the seeds sprout and establish some new growth. Once the young plants become strong enough, transplant them to a larger container or outdoor garden bed.
