## 4. Fertilization Techniques
### 4.1 Nutrient Needs
Dancing Lady Orchids require specific nutrients to thrive, but their nutritional needs may vary during colder days.
– **Fertilizer Schedule**: During the growing season, typically spring and summer, orchids benefit from regular feeding every two weeks. In the fall and winter, reduce feeding to once a month or less, as the plant’s metabolic activity decreases.
– **Type of Fertilizer**: Use a balanced orchid fertilizer, such as a 30-10-10 formulation, to provide essential macronutrients. A fertilizer high in nitrogen supports leaf growth, while a higher phosphorus content encourages blooming.
### 4.2 Application Methods
Applying fertilizer correctly is essential to avoid harming the roots or over-fertilizing the plant.
– **Dilution**: Always dilute fertilizers to half or quarter strength, especially during the winter months, to prevent nutrient burn.
– **Soil Application**: Apply fertilizer when the growing medium is slightly moist. This practice helps the plant absorb nutrients without stressing the roots.
## 5. Pest Management
### 5.1 Common Pests
Cold weather can drive pests indoors, increasing the risk of infestations. *Oncidium* orchids are susceptible to several common pests, including:
– **Spider Mites**: These pests thrive in dry conditions and can cause damage to leaves, leading to discoloration and webbing.
