Cultivation methods and matters needing attention of Ilex pubescens
Holly is suitable to grow in acidic soil with good drainage and air permeability, which is loose and fertile. When potted, you can directly buy nutrient soil for planting, or you can mix humus soil, sandy soil and rotten bark according to the ratio of 4: 2: 1, then add a little organic fertilizer and use it after mixing evenly.
Before using the soil dug in the field, spread it out in the air, get more sunshine, and let ultraviolet rays kill bacteria and insects in the soil. When changing pots, it is best to put some large particles such as ceramsite, light stone and broken bricks at the bottom of pots as drainage layers to increase the drainage capacity of pots, so that plants will not rot easily and grow better.
Attention should be paid to the prevention of pests and diseases when cultivating Ilex, and drugs such as chlorothalonil or carbendazim can be used for prevention.
Method for water and fertilizing holly
Holly also has high requirements for watering. Only with sufficient water supply can it flourish. Spring and autumn are the growing seasons of Ilex, so it is necessary to keep the basin moist frequently, but no water can accumulate. Don't water until the soil surface turns white and dry. Don't water the soil if the surface is not dry. In summer, the weather is hot and the water evaporates quickly, so you can water it properly. It is cold in winter, and the water evaporates slowly, so it is necessary to reduce the number of watering.
Holly is a plant that doesn't like fertilizer very much, especially the potted Holly. Excessive fertilization will make it grow in vain and reduce its ornamental value. In addition to applying basic fertilizer to the soil when changing pots, in the vigorous growth period of spring and autumn, the nutrient solution of 1~2 months can be used, which is mainly nitrogen fertilizer. No topdressing is needed in other seasons, so as not to burden plants and cause seedlings to burn to death.
