Where To Cut Orchid Stem After Flowers Fall Off

Knowing where to cut an orchid stem after the flowers fall off can help encourage new growth and potentially a new spike of flowers. Here’s a step-by-step guide on where and how to make those cuts:

Types of Orchids

First, determine what type of orchid you have. The common types are Phalaenopsis (moth orchids), Dendrobium, and Oncidium. The advice below primarily applies to Phalaenopsis orchids, which are the most common houseplant orchids.

Phalaenopsis Orchids

Identify the Nodes: Look at the flower spike (stem) after the flowers have dropped. You will see small nodes or bumps along the spike.
Choose a Node: Select a healthy node that is located below the point where the first flower bloomed. Typically, the second or third node from the bottom of the old flower spike is a good choice.
Make the Cut: Using sterilized scissors or pruning shears, make a clean cut about 1 inch above the selected node. Cutting above a node encourages the node to produce either a new flower spike or a ‘keiki’ (a baby plant).
Sterilize the Cutting Tool: This prevents the spread of diseases. You can sterilize the tools by wiping them with rubbing alcohol or a diluted bleach solution.
Monitor the Plant: After cutting, keep an eye on the plant. If the remaining stem begins to turn yellow or brown, the plant might naturally want to abort it. In this case, it’s best to cut the entire flower spike back to the base of the plant.

Other Types of Orchids

Dendrobium Orchids: For these, you usually don’t cut the stem after flowering as they can produce new buds on the old canes.
Oncidium Orchids: These should generally have their spent spikes cut all the way back to the base of the plant.

General Tips

Use Proper Tools: Always use sharp, sterilized scissors or pruning shears.
Seal the Cut: Some gardeners suggest sealing the cut with a little cinnamon powder which has anti-fungal properties to prevent infections.

Remember, the right care, including proper watering, light, and feeding, will also contribute to the health and flowering frequency of your orchid.
