Castor (ricinus communis) comes from East Africa. It has been acclimatized around the edge of the Mediterranean basin. Its seeds are toxic. They used to be used to make poison. Today, this shrub is appreciated for its ornamental qualities. TheCastor oil (ricinus communis) also has cosmetic properties.
To germinate, the castor bean (ricinus communis) should soak in water for 24 hours. We sow it indoors in April. After a month, the plants are planted out against a south-facing wall. In cold regions, cultivation is possible in a greenhouse. The soil must be well crumbled and enriched with humus to guarantee the growth of the plant.
The castor plant (ricinus communis) is sensitive to cold. To protect it, cut its stems in autumn. Then we cover it with mulch. This thick layer of chips isolates the base, which contains the germ buds. It also lets him breathe, in the event of a sudden change in weather. In spring, pruning is optional. It is used to restore a harmonious shape to this flowering shrub.
Cold pressed seeds give oil and a residue called castor cake (ricinus communis). It contains a lot of nitrogen, which makes it a natural fertilizer. It also fights against insect larvae present in the soil. In cosmetics, the oil strengthens hair and nails. Its antibacterial action is effective in case of skin problems.
