How to keep Indigofera Heterantha.
Light
Himalayan indigo comes from open habitats, such as sunny meadows and forest edges, which supply abundant light. It performs best in Full Sun but can also tolerate Partial Sun, adjusting well to different sunlight levels.
Temperature
Himalayan indigo is highly adaptable to different climate conditions, from very hot summers to cold winters. Still, it has a preferred temperature range for healthy growth. If temperatures get too high, the plant can experience heat and humidity stress that may kill it. In places where temperatures approach the lower limit of its cold tolerance, providing insulation is necessary to protect the plant.
Fertilizer
Timing is essential for fertilizing Himalayan indigo. Start fertilizing in early spring and continue once a month until early summer. Fertilizer encourages attractive blooms and provides energy during both dormant periods and active growth.
