20 Winter Orchid Care Mistakes (and How to Avoid Them)

Winter Orchid can be a challenging season for orchid care, with lower light levels, dry air, and colder temperatures affecting your plants. Orchids are resilient, but they need special attention during the colder months to thrive. If you’re not careful, it’s easy to make mistakes that can harm your orchids. In this blog post, we’ll discuss 20 common winter orchid care mistakes and how you can avoid them to ensure your plants stay healthy and bloom beautifully year-round.

1. Placing Orchids Near Draughty Windows

Mistake: Exposing orchids to cold drafts from windows or air conditioning can shock the plant, leading to stress or even death.

How to Avoid: Keep your orchids away from windows with cold drafts. Position them in areas with consistent temperatures and indirect light.

2. Overwatering During the Winter

Mistake: Many orchid owners continue to water on a set schedule during winter, despite orchids needing less water in this season.

How to Avoid: Water only when the top of the potting medium feels dry to the touch. Reduce watering frequency as orchids need less moisture in colder months.

3. Watering Orchids with Cold Water

Mistake: Using cold tap water can shock orchids, especially in winter when they are sensitive to temperature changes.

How to Avoid: Always use lukewarm or room-temperature water for your orchids to avoid temperature shock.

4. Ignoring Humidity Needs

Mistake: Winter air tends to be dry, and ignoring the orchid’s need for humidity can cause the leaves to curl or turn yellow.

How to Avoid: Maintain humidity levels around 50-70% by using a humidifier, placing the pot on a humidity tray, or grouping plants together.

5. Placing Orchids in Direct Winter Sun

Mistake: Orchids can burn if exposed to direct sunlight, even in winter, when the sunlight is less intense but still potent.

How to Avoid: Place orchids in bright, indirect light. A sheer curtain or a location that provides filtered light is ideal.

6. Not Adjusting Watering for Shorter Days

Mistake: Orchids still need to be watered based on the time of day, regardless of the shorter winter days.

How to Avoid: Adjust your watering schedule to account for the lack of light. Orchids generally need less water when they are not photosynthesising as much due to reduced daylight.

7. Not Checking for Pests During the Winter

Mistake: People tend to neglect pest control in the winter, but pests like mealybugs, aphids, and spider mites can still thrive in heated indoor spaces.

How to Avoid: Regularly inspect your orchids for pests and treat them with an insecticidal soap or neem oil if necessary.

8. Not Using Proper Potting Medium

Mistake: Orchids need a well-draining potting medium, but many people use too much moisture-retentive soil that can cause root rot in winter.

How to Avoid: Use a well-draining orchid mix made for your specific type of orchid. Consider adding extra perlite or bark to enhance drainage.

9. Using a Regular Fertiliser in Winter

Mistake: Fertilising orchids during their dormant winter period can encourage unhealthy growth and stress the plant.

How to Avoid: Avoid fertilising orchids during winter unless they are actively growing. If you fertilise, do so once a month using a balanced, diluted fertiliser.

10. Not Pruning Dead or Dying Flowers

Mistake: Leaving dead flowers on the orchid plant can attract pests and fungal diseases.

How to Avoid: Regularly remove any spent flowers or yellowing leaves to keep the plant healthy and encourage new growth.

11. Not Adjusting Temperature for Orchids

Mistake: Orchids are sensitive to temperature fluctuations. Placing them in an area that’s too cold or too hot can lead to stress.

How to Avoid: Keep your orchids in an area with stable temperatures, ideally between 60-70°F (15-21°C). Avoid sudden temperature changes near windows, doors, or heaters.

12. Not Providing Adequate Light

Mistake: Orchids can suffer from lack of light during the winter months due to shorter days and limited sunlight.

How to Avoid: Provide supplemental grow lights to make up for the lack of natural light, ensuring your orchids get at least 10-12 hours of light per day.

13. Placing Orchids in Overcrowded Spaces

Mistake: Grouping orchids too closely can hinder airflow, which is essential to prevent fungal and bacterial issues.

How to Avoid: Ensure your orchids are spaced out to allow proper airflow around each plant.This promotes healthy growth and helps ward off illness.

14. Not Checking for Root Health

Mistake: Orchids can develop root rot in winter if they are overwatered or their roots don’t have enough air circulation.

How to Avoid: Periodically check the roots by gently removing the orchid from its pot. Healthy roots should be firm and white. If they are mushy or brown, trim them and repot the orchid.

15. Neglecting to Repot When Necessary

Mistake: Failing to repot orchids when needed can lead to poor growth and root health, especially if the medium has broken down.

How to Avoid: Repot your orchid every 1-2 years or when the potting medium starts to degrade. Use fresh orchid mix and a pot that is only slightly larger than the previous one.

16. Using Too Large of a Pot

Mistake: Using a pot that’s too large for your orchid can cause the roots to become waterlogged, leading to root rot.

How to Avoid: Choose a pot that is only slightly larger than the current root ball. Orchids prefer to be a little root-bound.

17. Placing Orchids Near Heat Sources

Mistake: Placing orchids too close to heaters, radiators, or fireplaces can dry them out and cause the leaves to burn.

How to Avoid: Keep your orchids away from direct heat sources. Instead, place them in areas with indirect warmth and steady air circulation.

18. Over-Pruning or Cutting Flowers Too Early

Mistake: Pruning too much or cutting flower spikes too early can prevent your orchid from blooming again in the future.

How to Avoid: Wait until the flower spike turns yellow and dries out naturally before pruning. This allows the plant to store energy for next season’s bloom.

19. Ignoring Orchid Type Differences

Mistake: Not understanding the specific needs of your orchid species can result in incorrect care during the winter months.

How to Avoid: Research the specific care requirements of your orchid species. Different orchids, like Phalaenopsis, Cattleya, and Dendrobium, have unique winter care needs.

20. Giving Up on Orchids After a Setback

Mistake: When orchids show signs of stress, many people give up, thinking they won’t recover.

How to Avoid: Be patient and observe the orchid carefully. With proper care, most orchids can bounce back from winter setbacks, even if they’ve experienced some issues like yellowing leaves or slowed growth.

Caring for orchids during the winter months requires a little extra attention to detail, but by avoiding these 20 common mistakes, you can ensure that your orchids thrive through the cold season. By providing them with the right temperature, humidity, light, and watering schedule, your orchids will stay healthy and may even reward you with beautiful blooms when spring comes.
