How to Care for Orchids During Summer: Cultivating Techniques and Seasonal Changes

Orchids are exotic and beautiful plants that bring a touch of elegance to any home or garden. While they can be relatively easy to care for once you understand their needs, summer introduces some specific challenges and opportunities for these stunning flowers. Here’s a comprehensive guide on how to care for your orchids during the warmer months, including the essential changes from winter to summer.
Understanding Seasonal Changes: Winter to Summer

Orchids, like all plants, have different needs as the seasons change. During winter, orchids often enter a period of dormancy with lower light levels, cooler temperatures, and less water. As summer approaches, several factors shift, necessitating adjustments in care to ensure your orchids thrive.

1. Light:
    Winter: Orchids typically receive less light in winter, and artificial lighting may be necessary.
    Summer: Increased daylight hours mean more natural light. However, direct sunlight can be too intense and may scorch the leaves. Place orchids in a spot with bright, indirect light.

2. Temperature:
    Winter: Cooler indoor temperatures are suitable, often around 60-70°F (15-21°C).
    Summer: Orchids prefer temperatures between 70-85°F (21-29°C) during the day. Ensure the temperature doesn’t drop below 60°F (15°C) at night.

3. Humidity:
    Winter: Indoor air is often drier due to heating systems, requiring humidifiers or pebble trays.
    Summer: Natural humidity levels are higher, but you might still need to supplement humidity during dry spells.

4. Watering:
    Winter: Water less frequently, about once every 10-14 days.
    Summer: Increased evaporation and growth rates mean more frequent watering, usually every 5-7 days. Ensure good drainage to prevent root rot.

Cultivating Techniques for Summer

1. Light Management: Orchids thrive in bright, indirect light. During summer, move your orchids away from direct sunlight. An east-facing window is ideal, providing morning light that is less intense. If your only option is a south or west-facing window, use sheer curtains to diffuse the light.

2. Temperature Control: Ensure your orchids stay within their preferred temperature range. During heatwaves, move orchids to a cooler area or use fans to circulate air. Avoid placing orchids near air conditioners or vents, as cold drafts can damage the plants.

3. Humidity Maintenance: Orchids prefer humidity levels between 50-70%. Use a humidity tray or room humidifier if natural humidity is insufficient. Misting orchids can help, but avoid doing this late in the day to prevent moisture from sitting on the leaves overnight, which can cause fungal issues.

4. Watering Techniques: Water orchids thoroughly, allowing water to run through the potting medium and out of the drainage holes. Water early in the day to allow the plant and medium to dry out by evening. This practice helps prevent bacterial and fungal problems.

5. Fertilizing: Orchids are actively growing in summer, making it the perfect time to fertilize. Use a balanced orchid fertilizer (20-20-20) diluted to half strength every two weeks. This helps support vigorous growth and blooming.

6. Repotting: Summer is a good time for repotting if your orchid has outgrown its pot or the medium has broken down. Choose a well-draining orchid mix and a pot that allows for adequate air circulation around the roots.

Troubleshooting Common Summer Issues

1. Sunburn: Symptoms: Yellowing or dark, dry spots on leaves. Solution: Move the orchid to a shadier spot and trim damaged leaves if necessary.

2. Heat Stress: Symptoms: Wilting, yellowing leaves, and droopy flowers. Solution: Increase air circulation and ensure the plant isn’t exposed to temperatures above 85°F (29°C) for prolonged periods.

3. Pest Infestation: Symptoms: Presence of insects like aphids, mealybugs, or spider mites. Solution: Regularly inspect your orchids and treat infestations with insecticidal soap or neem oil.

4. Fungal Infections: Symptoms: Black or brown spots on leaves and stems. Solution: Ensure good air circulation, reduce humidity, and use fungicides if necessary.


Caring for orchids during the summer requires a balance of light, temperature, humidity, and proper watering techniques. By making these seasonal adjustments, you can ensure that your orchids remain healthy and vibrant throughout the summer months. Remember, each orchid variety may have specific needs, so always research the particular requirements of your plants. With the right care, your orchids will not only survive the summer but flourish, bringing beauty and elegance to your space year-round.
