Learn Why Orchid Buds Drop Before Blooming in Summer and How to Prevent It to enjoy full, healthy blooms all season.
Orchids are beautiful plants, but they can be tricky to grow. One common problem many people face in summer is when orchid buds suddenly fall off before they open. This can be very disappointing, especially after waiting weeks for blooms. In this article, we’ll explain why orchid buds drop before blooming in summer and what you can do to prevent it.
Why Orchid Buds Drop Before Blooming in Summer and How to Prevent It
1. Sudden Temperature Changes
Orchids are sensitive to temperature. If your orchid experiences a quick rise in heat or a big difference between day and night temperatures, it may drop its buds. This often happens when orchids are moved from an air-conditioned room to a hot outdoor space.
2. Too Much Heat
High summer temperatures can stress the plant. Orchids prefer moderate warmth, not extreme heat. If it gets too hot, especially if there’s not enough airflow, the plant may not be able to support bud development.
3. Low Humidity
Summer heat often comes with dry air. Orchids need humidity to thrive. Dry air causes the buds to lose moisture, leading to bud blast (when buds dry out and fall off before blooming).
4. Not Enough Water or Overwatering
In summer, orchids need more water to stay hydrated. If you forget to water or the roots dry out, the plant may drop its buds. On the other hand, too much water can rot the roots, also stressing the plant.
5. Strong Sunlight
Orchids need bright light, but harsh summer sun can burn the plant. Direct sun can cause heat stress and leaf damage, which may also lead to bud loss.
6. Change in Environment
Moving your orchid to a new location in the summer (such as from indoors to outdoors) can shock the plant. Even a small change in light or air can trigger bud drop.
7. Pests and Diseases
Insects like aphids, mealybugs, or spider mites often attack orchids in summer. They feed on the buds and weaken the plant. Fungal infections, often caused by high humidity and poor air circulation, can also lead to bud loss.
How to Prevent Orchid Buds from Dropping in Summer
1. Maintain a Stable Temperature
Keep your orchids in a spot with stable temperatures between 18°C and 27°C (65°F to 80°F). Avoid placing them near air vents, fans, or open windows with hot drafts.
2. Increase Humidity
Use a humidity tray or a room humidifier. You can also mist the plant lightly (but not the buds directly) in the morning. Try to keep humidity between 50% and 70%.
3. Water Carefully
Check the potting mix regularly. Water when the top feels dry, but don’t let the roots sit in water. Use room-temperature water to avoid shocking the roots.
4. Give Gentle Light
Place your orchid in bright, indirect sunlight. Use a sheer curtain if the light is too strong. Avoid direct sunlight, especially in the afternoon.
5. Avoid Moving the Plant
If your orchid has buds, try not to move it around. Sudden environmental changes can confuse the plant and cause bud drop.
6. Watch for Pests
Check the buds and leaves often for bugs or sticky spots. Wipe off pests with a damp cloth or use a safe insecticidal soap if needed.
7. Provide Good Air Circulation
Good airflow helps prevent diseases in humid summer weather. Use a small fan nearby if the room feels stuffy, but avoid blowing directly on the plant.
