Understanding the environmental needs of narcissus is essential for successful cultivation. Here are key factors to consider:

1. Narcissus thrives in a warm and humid climate, particularly in regions with mild summers and no extreme heat, as well as rainy springs. This environment helps promote healthy growth and flowering.

2. These plants require plenty of water and nutrients. They prefer loose, nutrient-rich soil that is slightly acidic or neutral, with good drainage. While they can tolerate some drought, they are not very resilient when it comes to poor conditions.

3. Narcissus prefers full sunlight but can also tolerate partial shade. However, too little light may hinder their ability to produce and store nutrients effectively.

4. Adequate daylight is crucial during the flowering period to ensure vibrant blooms.

5. As a short-day plant, narcissus typically requires around 10 hours of light per day to initiate flowering.

6. Different stages of growth demand specific environmental conditions. Proper care at each phase ensures better development and blooming.

7. During the growing season, narcissus prefers cooler temperatures, ideally between 10°C and 20°C. It can tolerate temperatures as low as 0°C.

8. In the later stages, especially when bulbs are developing, warmer temperatures (20–25°C) and higher humidity (70–80%) are ideal for bulb expansion.

9. Compared to many other flowers, narcissus has higher water needs. Ensuring consistent moisture during its active growth phase is important. However, it should be allowed to dry out slightly later on to support proper bud formation.

10. Flower bud differentiation occurs during the hot, dormant summer period. In natural conditions, buds don't form until after harvest, and the process begins once the plant is rested.

11. The development of flower buds is best supported by cooler temperatures, around 9°C, which helps encourage strong and healthy blooms.

12. A sunny environment is necessary for optimal growth. Insufficient light can lead to weak growth and poor nutrient accumulation, which negatively affects the plant’s overall health and flowering potential.
