Comprehensive Guide on Orchid Pruning: Tips and Techniques

If you’re an orchid enthusiast, you probably like to engage in lively discussions about how and when to prune orchids. While the task may seem daunting, with the right knowledge and tools, it’s actually quite simple.

Before you start pruning, it’s crucial to ensure that your tools are clean. Wipe your clippers or scissors with isopropyl alcohol to prevent the spread of disease. Only remove leaves if they are diseased, dead, or deformed. Here is a breakdown of how to prune different types of orchids:

How to Prune Different Types of Orchids

Table of Contents

Phalaenopsis
Known as the moth orchid, Phalaenopsis is a popular genus due to its vibrant blossoms that last for months. When the flowers fade, prune the flower stem off at the base. Leave about an inch of the stem to reduce the risk of injuring the main stalk. If the stem remains green after the blossoms drop off, new flowers may grow in a few weeks.
Dendrobium
To encourage Dendrobium to keep producing blossoms, snip off drooping flowers at the base. Wait a few weeks after the flower stem is bare, as it may produce a second flush of blossoms.
Brassavola, Cattleya, Cymbidium, and Oncidium
These orchids produce multiple pseudobulbs from which flower spikes emerge. Cut the flower stalks at the base once the blossoms are gone. Remove any dead or diseased leaves to improve air circulation.
Calanthe, Zygopetalum, and Hybrids
After the flowers drop, prune the flower stalk back to the first “notch” to encourage regrowth from that area. Remove dead or damaged leaves and check the roots for any issues.
Cycnoches
During the winter, Cycnoches species go dormant and drop their leaves. Wait until the summer after new growth has developed to prune any bare areas. Trim off any dead roots and pseudobulbs.
Additional Considerations for Sympodial Species
For orchids that produce pseudobulbs from which flowers and leaves sprout, such as Cattleya species, pruning techniques can influence the blooming rate. Encourage multiple flower stalks by pruning regularly.
Trimming Aerial Roots
Aerial roots serve the purpose of anchoring the plant and absorbing nutrients. Remove any roots that are brown, yellow, soft, or shriveled. Cut them back close to the stem using clean pruners.

Understanding how to prune different types of orchids is essential to their overall health and blooming potential. By following proper pruning techniques, you can keep your orchids looking vibrant and thriving.
