Holly likes fertile soil, which grows well in humid and well drained acid soil. The requirements for soil are not strict, so it can also grow well in general soil.
Holly likes warm climate and has strong cold resistance. The suitable temperature for the growth of holly is from - 10 ℃ to 30 ℃, which can withstand low temperature in winter. However, in summer, to avoid high temperature, shade measures should be taken, or ventilation should be strengthened, and spray water on the leaves like plants to reduce the temperature. In terms of light, Holly can withstand shade. In summer, when the light is particularly strong, it is necessary to shade to avoid strong light.
The growth of holly needs to ensure sufficient water supply to keep the basin soil moist, especially in spring and autumn when the growth is vigorous, water supply must be appropriate. When the temperature is high in summer, the evaporation is large, and the basin soil will be relatively dry. Water frequently and spray the holly plants to keep the air humidity. Generally, fertilization does not need to be done frequently. In the spring and autumn growing season, appropriate topdressing can be done once or twice, and the main thin liquid fertilizer is nitrogen fertilizer.
The propagation of Ilex is mainly sowing propagation and cutting propagation. Sowing propagation is carried out in March of spring, and germination is required before sowing. Cutting propagation is to cut the tender branches in Meiyu season, and use rooting powder to drive the roots before cutting.
Holly is a more shear resistant plant, and in order to watch, it can often be reshaped and pruned. It can be pruned in summer, or in autumn, according to the needs, Holly can be pruned into various shapes, and appropriately pruned too dense branches to make them grow healthily.
