Planting

Choose a well-drained, sunny location that receives 6 to 8 hours of sunlight per day. Next, dig a hole which is three times the width of the rootball and as deep as the rootball. Then, remove the plant from the container and place it upright in the hole so that the top of the rootball is flush with the ground.

At this point, backfill the hole and tread down lightly. Once the hole is completely filled, water the soil to let it settle and to eliminate air pockets. Finally, spread 3 to 5 inches of mulch around the plant to enrich the soil and help retain moisture and control weeds.

Light

This tree does well in sunlight, so choose a location that receives at least 6 hours per day. However, without sufficient light, you may not be able to see the spectacular red and orange flowers that characterize the himeshara.

Watering

We recommend watering Poinciana once or twice a week. If you are not sure when to water, check to see if the top 2 inches of soil are dry. If the soil is dry, it is time to water.

Fertilizer

Apply a slow-release fertilizer once a year in early spring, before new shoots emerge. Then, water the surrounding soil to allow the fertilizer to penetrate the roots. Follow the directions for use on the packaging.

Soil Requirements

Temperature

The Royal Poinciana Tree is native to tropical forests, which is why it grows well in warm, humid environments. It cannot tolerate temperatures below 45 degrees Fahrenheit. It can easily be grown outdoors in parts of Florida, Texas, and Hawaii. However, it is only suitable for reliably warm climates.

Pruning

Prune back any dead or diseased branches you find. Also note where branches rub against each other and prune them back as well. In early spring, before new shoots emerge, prune large branches that are low on the trunk or high on the trunk.

Pruning may also be done to shape the tree. Branches that are outside the silhouette should be cut off to achieve a fuller, wider silhouette, as they are more likely to break off in windy conditions. Aim to keep all major branches approximately 8 to 12 feet above the ground.

Pests and Diseases

Flame trees do not attract many insect pests, but a type of caterpillar may eat the foliage. However, they do not defoliate the entire tree. Additionally, spider mites can be a problem, especially if the tree is not in a humid environment.

Furthermore, if you find spider mites, increase humidity or take the plant outdoors. Silkworms can also be a problem. They appear under the leaves and can be removed with a cotton swab dipped in alcohol.

Root rot is a type of fungus that can rot the roots. To reduce root rotting, choose a well-drained soil that will reduce the chance of this fungus entering the soil. Another possible disease of Poinciana is stem canker disease, characterized by bark lesions and death. This fungal disease responds well to chemical fungicides.

Poinciana is not often plagued by pests and is a relatively low-maintenance tree. Spider mites and scale insects may be attracted to it, but a healthy flame tree can withstand an infestation. It may also attract termites and borers, but if you suspect an infestation, it is best to contact a professional arborist to take care of it.
