Orchids are admired for their exotic appearance and delicate blossoms. These stunning plants can be an excellent addition to any home or garden. While most people purchase orchids from a nursery, it is also possible to grow them from roots. In this article, we will discuss three ways to successfully grow orchids from roots: division, cuttings, and aerial roots.

1. Division

Division is the most common way of propagating orchids and is suitable for mature plants with multiple pseudobulbs. The process involves separating the orchid into smaller pieces, each containing at least one healthy pseudobulb and root system.

Step-by-Step Guide:

a) Wait until the orchid has finished blooming to avoid shocking the plant.

b) Remove the plant from its pot gently, exposing the root system.

c) Identify clusters of pseudobulbs connected by a rhizome and carefully cut through the rhizome using a sterile cutting tool.

d) Pot each division into a separate container filled with fresh orchid potting mix.

e) Water the divisions sparingly until new growth appears and then resume regular care.

2. Cuttings

Cuttings are an ideal method if your orchid has long stems or keikis (baby orchids). This technique encourages new plants to sprout directly from the stem of a parent plant.

Step-by-Step Guide:

a) Choose a healthy stem on your orchid that has at least two or three nodes.

b) Using sterilized scissors, cut the stem about 1 inch (2.5 cm) below a node.

c) Allow the cutting to air dry for a day before placing it in moist sphagnum moss or another well-draining growing medium.

d) Place the cutting in a warm and humid environment, maintaining high humidity levels around 70%–80%.

e) Watch for new roots to emerge from the nodes and repot the new orchid once a healthy root system has developed.

3. Aerial Roots

Some orchids, such as Phalaenopsis and Vanda, produce aerial roots which can be used for propagation.

Step-by-Step Guide:

a) Identify a healthy aerial root that has at least 1–2 inches (2.5–5 cm) in length.

b) Carefully cut the root from the parent plant using a sterilized cutting tool.

c) Immediately dip the cut end in a rooting hormone to promote growth.

d) Place the aerial root into a container filled with moist sphagnum moss or another suitable growth medium.

e) Keep the temperature and humidity high to encourage root development, providing support to keep the cutting upright if needed.

f) Once a well-developed root system exists, transfer the cutting to an orchid potting mix and care for it according to its species requirements.

In conclusion, orchids can be propagated in several ways using roots. Utilizing division, cuttings, or aerial roots allows enthusiastic growers to expand their collection while learning more about these fascinating plants. Remember that patience is vital; propagation success may take time and vary depending on factors such as orchid species, environment, and care.
