Orchids are beautiful flowers that are great for growing indoors. While these little plants are fairly easy to look after, special care must be taken when pruning orchids. Follow these steps to properly prune off old wood to make room for new blooms.
How to Prune an Orchid
Different types of orchids require different pruning methods. Use the orchid pruning tips below to keep your orchids looking good and healthy.
Make sure you have super sharp pruning shears to use on your orchid. The sharper the shears, the cleaner the cut will be. A clean cut makes for a healthier orchid.
While the orchid is still blooming, cut back the flowers that are fading. Removing the orchid blooms that have finished will not only keep your plant looking neat but will increase its vitality.
Make a clean even cut directly back to the main branch. Keep this up while the plant is blooming.
When the Phalaenopsis orchid is completely done blooming and all the flowers have faded, you can do the major pruning. Most orchids will go dormant in the fall, so plan on doing your pruning then.
Trim the stem that had the blooms on it off about an inch away from the main stalk. Make the cut clean and even. If there are any places on the stalk that have turned yellow or brown, cut them back completely so that the plant will grow back healthier.
Remove the orchid from its pot. Prune away any dead or damaged roots.
Replant the orchid in a bigger pot each year so that it has more room to grow.
If your orchid is fairly young, you want to encourage it to grow bigger roots and blooms. The best way to cut orchid plants when they are young is to trim the stalk all the way back to one inch from the base of the plant. As it grows back, it will have stronger roots, bigger leaves and larger blooms.
If your orchid is a Dendrobium type, trimming is a little different. Trim the flowers off as they fade but leave the stem. Next year it will flower on the same stalk. Trim roots and re-pot as normal.
More Orchid Pruning Tips
Make sure your plant is near a window for the best lighting. Plants that do not receive enough light will not be as healthy as those that receive sufficient light. The most common problem with not enough light is lack of blooming or quality blooms.
Water your plant carefully. Try to never wet the leaves of an orchid when you water it. If you do, dry the leaves with a paper towel so that no water is left sitting on them.
Don’t allow excess water to sit at the base of the plant. Water that is not allowed to drain away from the pot will cause the roots to rot and possibly kill the plant. Watering too frequently will also cause this. In the summer, water orchids once a week. In the winter, once every 2 weeks is sufficient.
