Gardening Advice

Sunlight

Prefers full sun. Exposure to direct sunlight ensures healthy growth and vivid flowering.

Watering

Requires moderate watering during the growing season. Water generously when the soil becomes dry, but avoid excessive moisture that could cause root rot.

Soil

Thrives in fertile, well-drained soil. It can adapt to sandy soil, but grows better with nutrient-rich conditions. Mixing compost or leaf mold before planting is recommended.

Fertilizer

Apply a phosphorus-rich fertilizer once a month during the flowering season to enhance blooming. Avoid excessive nitrogen, which encourages leafy growth at the expense of flowers.

Pruning

Prune during the dormant season in winter to encourage flowers in the next cycle. Remove old or unnecessary branches to improve shape and stimulate new growth.

Cold resistance

As a tropical species, it is vulnerable to frost. In colder climates, it is best grown in containers for easy relocation, or protected indoors during winter.

Conclusion

The Erythrina crista-galli is a tree that instantly transforms a garden or park with its radiant red blossoms and tropical atmosphere.

With proper care, it will reward you each year with its spectacular flowers. I recommend adding this magnificent tropical plant to your garden to enjoy its vibrant beauty.
