Should you prune the flower spike of Phalaenopsis after it fades? Master these practical tips to help your orchid recover faster and even rebloom!


### I. Methods to Determine Pruning Timing
#### When the spike is withered and yellow:
If the flower spike becomes shriveled, yellow, or feels brittle when touched, it indicates the plant has reabsorbed all nutrients. Cut it off 1-2 cm from the base to prevent nutrient loss from the remaining stub and reduce bacterial risk, allowing the plant to focus on new leaf and root growth.

#### When the spike remains green:
1. **Retain for observation**: Wait 1-2 weeks—some varieties may grow new flower branches or plantlets from the spike nodes.
2. **Prune to promote strength**: Cut diagonally 15-20 cm above the base, leaving 1-2 nodes to encourage leaf and root development.


### II. Post-Pruning Care Guidelines
#### Watering:
Reduce frequency—water only when the surface of sphagnum moss or bark substrate feels dry. After thorough watering, empty the tray immediately to prevent root suffocation.

#### Light:
Move the orchid to a bright, diffused light spot indoors (e.g., 1 meter from a window). It can tolerate more sunlight in spring/autumn, but shade it at noon in summer to avoid leaf burns.

#### Fertilization:
Wait 1 month until the plant stabilizes before fertilizing. Use high-nitrogen fertilizer for rapid leaf growth or balanced orchid fertilizer for overall development, diluted 1000x and applied every 10 days.

#### Growth signs:
New aerial roots at the base or tender green leaves at the top indicate the plant has recovered—resume normal care.


### III. Important Precautions
1. **Use sharp pruning shears disinfected with alcohol or carbendazim solution to prevent wound infection and rot.**
2. **If the plant has sparse leaves and shriveled roots, cut the spike at the base to reduce stress. Focus on strengthening the plant before expecting reblooming.**
3. **Maintain 18-28°C temperature and 50%-70% humidity during the critical 1-2 week recovery period. Ventilate regularly or use a fan on low speed to prevent pests and diseases.**


Following these steps, most Phalaenopsis will rebloom within 6 months to a year.
