### 4. Temperature Regulation

Temperature fluctuations can also contribute to plant stress. Dendrobium anosmum prefers specific temperature ranges for optimal growth.

#### Best Practices for Temperature

– **Ideal Temperature Range**: Aim for daytime temperatures between 20°C to 30°C (68°F to 86°F) and slightly cooler at night (around 15°C to 20°C or 59°F to 68°F).
– **Avoid Sudden Changes**: Protect your orchids from sudden temperature changes caused by drafts, air conditioning, or heating vents.

## Nutritional Support

### 5. Balanced Fertilization

Nutritional stress can arise from deficiencies in essential nutrients. A balanced fertilization regimen can help alleviate this stress.

#### Best Practices for Fertilization

– **Use Orchid-Specific Fertilizers**: Choose a balanced fertilizer formulated specifically for orchids, such as a 30-10-10 or 20-20-20 blend.
– **Fertilizing Schedule**: During the growing season (spring and summer), fertilize every two weeks. In the dormant season (fall and winter), reduce fertilization to once a month or as needed.
– **Dilution**: Always dilute the fertilizer to half the recommended strength to avoid over-fertilizing, which can stress the plant.

### 6. Soil and Potting Medium

The right potting medium is essential for healthy root development and stress reduction.

#### Best Practices for Potting

– **Choose a Well-Draining Medium**: Dendrobium anosmum prefers a potting mix that allows for excellent drainage, such as a combination of bark, sphagnum moss, and perlite.
– **Repotting**: Repot your orchids every 1-2 years or when the potting medium breaks down. This helps ensure healthy root growth and prevents root rot.

## Pest and Disease Management

### 7. Regular Inspections

Pest infestations and diseases can cause significant stress to Dendrobium anosmum. Regular inspections are key to early detection and management.

#### Best Practices for Pest Management
