A Detailed Guide to the Propagation Methods and Precautions for Coral Tree (Erythrina crista-galli)

The coral tree (see details) is not difficult to cultivate. Although it likes high temperatures, it still has fairly strong cold tolerance and is robust by nature, making it an excellent ornamental and street tree. It is now cultivated in South China and the Taiwan region of China. So how should the coral tree be propagated?

Coral Tree

I. Propagation by Seed

It is best to sow the seeds as soon as they are collected. Do this in early summer. Soak the seeds appropriately before sowing, then sow them directly in a seedbed. The seedbed soil should preferably be loose sandy loam. After sowing, cover with soil to about twice the height of the seeds, and take care to spray water to keep it moist. Seedlings will emerge in about 10 days, and after 1 month, when the seedlings have grown to 20 cm, transplant them.

II. Propagation by Cuttings

Cut semi-lignified branches about 20-40 cm long and insert them into a sand bed or loose seedbed, keeping it moist. They will take root and sprout in about 15 days, and become established seedlings in 1-2 months. In the coastal areas of South China, long-branch cuttings are commonly used, and they will take root after 1-2 months.

How to Grow Coral Tree - Propagation Methods for Coral Tree

The coral tree is a deciduous shrub or small tree, with stems and leaf stalks bearing slight prickles. Today we will share with you knowledge on how to grow the coral tree and how to propagate it.

How to Grow Coral Tree

The coral tree gets its name "coral tree" because its flowers resemble a rooster's comb. It is a deciduous shrub or small tree. For coral trees growing in China, the flowering period is about April to July. The flowers are red when they bloom, and the flowering period is long, so it is suitable for courtyard viewing and also for central road landscaping. Its trunk can reach 50 cm in diameter, and the tree height is about 5-8 m, and it can even grow to around 10 m.

It likes light and also tolerates mild shade. It likes high temperatures but has fairly strong cold tolerance. It is highly adaptable, robust by nature, drought-tolerant and tolerant of poor soil, and can also resist salinity and alkalinity, but it does not tolerate waterlogging. It is not demanding about soil, but grows best in well-drained fertile loam or sandy loam. When grown in pots in the north, the suitable temperature in winter should be kept above 4°C. It is not particular about soil when cultivated, and planted in full sun or partial sun it can grow rapidly. The tree form is relatively small, suitable as a street tree or background tree.

How Long Is the Flowering Period of Coral Tree - What Propagation Methods Does Coral Tree Have

The coral tree looks like a rooster's comb, hence the name "coral tree". Because its flowering period is relatively long, it is quite suitable for central road landscaping. So when is the flowering period of the coral tree? What propagation methods does the coral tree have? Let's find out together.

I. Flowering Period of Coral Tree

Flowering period of coral tree: April to October.

The coral tree has papilionaceous (butterfly-shaped) corollas and racemose inflorescences. But unlike the native Erythrina of China, it does not bloom in radially symmetrical tiers like a pagoda; instead, it is bilaterally symmetrical, with branches blooming upward and forward. Its fruit is a pod only a few centimeters long. The pod usually contains 4-5 seeds, which are chestnut brown, round and bean-shaped, sparsely distributed within the pod.
