Orchid Care in November: Preparing for Fall and Colder Temperatures
As the vibrant fall season progresses and the weather grows colder, our orchids enter a period that requires special attention to thrive through winter. November is the perfect time to adjust their care routines and ensure they remain happy and healthy as temperatures dip. Whether you’re growing orchids indoors, in a greenhouse, or on a windowsill, here are some essential tips to help your orchids adapt to the fall season and prepare for the colder months.
1. Adjusting Light and Temperature
During November, natural light starts to diminish, and many orchids will benefit from supplemental lighting. Orchids that require more light, like Cattleyas and Vandas, may need placement under grow lights to meet their light requirements. If you don’t have grow lights, consider placing them near south-facing windows, but be mindful of cold drafts.
Temperature changes can also be tricky for orchids this time of year. As nights grow cooler, try to maintain nighttime temperatures between 55-65°F (12-18°C) for most orchids. Some varieties, like Cymbidiums, can handle cooler nights and may even need the temperature drop to encourage blooms. However, protect tropical orchids from drastic cold temperatures, especially if your home tends to get chilly at night.
2. Watering Wisely
With the change in season, orchids enter a period of slower growth. Orchids in active growth require more frequent watering, but during the fall, they typically slow down, requiring less water. Reduce your watering schedule slightly in November, letting the top layer of the potting medium dry out more than usual. Overwatering in colder months can lead to root rot, so always check the medium before watering.
Humidity is another key element to consider. If you’re growing orchids indoors, you may notice that heating systems dry out the air. Use a humidifier near your orchids or place a humidity tray with pebbles and water to help maintain a humidity level between 40-60%.
3. Fertilizing with Caution
In November, orchids generally require less fertilizer, especially those that enter a rest period, like Dendrobiums. Scale back on fertilizing to every four to six weeks, and use a balanced, diluted orchid fertilizer to avoid burning delicate roots. For orchids still in active growth, apply fertilizer at half the recommended strength.
4. Seasonal Repotting Needs
While fall isn’t the most ideal time to repot most orchids, certain situations may call for repotting even now. If you notice any signs of root rot or if your orchid is outgrowing its pot and appears root-bound, it’s worth repotting. Otherwise, you can wait until spring when most orchids are in active growth.
5. Watch for Pests
As we move orchids indoors to escape the cold, some unwanted pests, like spider mites and aphids, may find their way onto our plants. November is a good time to do a careful inspection of your orchids, checking both the leaves and the undersides. Using an insecticidal soap or rubbing alcohol on a cotton swab can help remove any pests you may find.
6. Preparing for Bloom Season
One of the joys of cooler months is the promise of winter blooms! Many popular orchids, such as Phalaenopsis and some varieties of Cattleyas, start setting their flower spikes in the fall. Ensure these orchids have the right temperature and light conditions, and avoid moving them too much once buds start forming. For Phalaenopsis, exposure to slightly cooler nights can help initiate flower spike development, so this time of year is perfect for encouraging bloom spikes.
7. Enjoying the Beauty of Orchids in Fall
Orchids bring joy all year round, but there’s something particularly magical about their elegant blooms in the midst of autumn's earthy tones. Display your orchids prominently and enjoy their beauty as they add color to the season’s ambiance. Consider arranging blooming orchids with seasonal décor like miniature pumpkins, pinecones, or autumn leaves for a unique and stunning fall display.
Final Thoughts
Orchid care in November is all about balancing the transition between seasons. By adjusting their environment, watering schedule, and light exposure, you can help your orchids stay healthy and vibrant through the fall and winter months. Enjoy this cozy season with your orchids, and look forward to the stunning blooms many of them will soon reveal!
