Delonix Flame Tree Care. Flame trees perform best in large, open spaces and full sunlight.

Give the plant lots of water during the summer, but ensure that the soil dries out between watering

temperature ranging between 10 - 36°C

The flame tree tolerates a pH value between 4.5 and 7.5, so avoid very calcareous water. Fertilizing: Apply solid organic fertilizer every four weeks or use a liquid fertilizer every week during the growing season. Use a fertilizer with a balanced N-P-K ratio to promote healthy growth as well as opulent flowering.
