As we know, coconuts use water to spread seeds. Coconut fruit is a kind of stone fruit, the outer skin is thick and loose wood, and the middle is made of solid brown fiber. When it falls into the water after ripening, it will float on the water like a ball and will not rot. Sometimes it will drift with the sea for several Qian Qian meters. Once it hits a shoal or is washed to the shore by the tide, it meets a suitable environment, where it will germinate and grow and resettle. This is the secret of coconut trees growing around tropical coasts and islands. In addition, although the requirements of coconut trees on soil are not very strict, the soil with sufficient water is the most suitable, and the water around coastal islands is the most abundant. Moreover, seawater often washes the coast, leaving rich nutrients in the soil, but also bringing a lot of salt. Coconut trees especially like saline soil, growing in such water and soil, with the right temperature and sufficient sunshine, their leaves grow very fast and well. Coconut trees can grow as high as seven or eight stories! Coconut trees bloom all year round, but coconuts only mature in the hottest time of the year. Coconut's special temperament makes it particularly attached to high temperature, so coconuts are the most common in tropical coastal areas. Coconut trees always travel around the sea along the current to find a suitable place to grow.
