The Erythrina crista galli prefers fresh soils, well drained, rich in organic matter. The erythrin is however a rather rustic shrub and can also adapt in soils with different characteristics. During the cold season, when temperatures are very cold, it may be advisable to protect the base of the plant with mulch, dry leaves or straw, so as to prevent the erythrin from being damaged by excessive frost.
The multiplication of Erythrina crista galli is done by seed, using in spring the seeds of the previous year; often it is better to wet the seeds in warm water for a few hours before sowing them.
In spring or autumn, cuttings can also be made, which are to be rooted in a mixture of peat and sand in equal parts. It is good to protect the youngest plants from the climatic changes and especially in the coldest periods, at least for the first 2 or 3 years of life.
