How to Care for the Plant

Water
The cultivated plants should undergo at least a two-week period of drought, so that the growth mature and to stimulate flowering. In the period of strong growth, the plants needs abundant watering and the growing medium should be moist. Watering every 2-3 days during the hottest and the brightest period of the year corresponds to the conditions of most natural habitats.
Fertilizer
During the period of strong growth, the plants should be fertilized every week with 1/4-1/2 of the recommended dose of fertilizer for orchids. You can use fertilizer with low nitrogen content and high phosphorus content in autumn. It improves flowering in the next season and strengthens new growth before winter.
Sunlight
Brassavola nodosa needs a light level of 25000-35000 lux. These plants are able to tolerate higher light intensity if they are gradually accustomed to it. When the light intensity is higher, you need to ensure high humidity and significant air movement. To avoid burns, you also need to ensure that water does not remain on the leaves during the strongest sunshine.
