How to care for French holly
The network introduces how to care for French holly and the explanation of the cultivation methods of green plants and flowers. Let's learn about it together below.
French holly refers to the Japanese coral tree, not the kind of holly we understand. Many people may not master the cultivation techniques of French holly. Planting French holly at this time may affect its growth. If you can plant it according to scientific methods, it may reduce various problems, and the survival rate of French holly will be relatively higher. Below, China Landscape Network provides a detailed introduction to the cultivation techniques and maintenance methods of French holly.
【French Holly Planting Techniques】
1. Selection of French holly seeds: Only seeds collected in the same year and preserved using scientific methods are the prerequisite for everything. Do not use unripe seeds, as efforts to plant them later will be futile. Please choose seeds carefully.
2. How to germinate French holly seeds: If the holly seeds are not treated for germination, they often take a year to sprout. Remove the fruit skin, wash clean, and treat the seeds with moist sand and low-temperature stratification to induce germination.
3. French holly planting soil: The soil should be disinfected and pest-eliminated before planting. It is suitable for planting in moist semi-shaded areas and prefers fertile soil to grow more vigorously.
4. French holly sowing method: French holly can be sown in autumn or stored in sand in winter and sown in spring of the following year. The seeds can germinate and grow into seedlings after 30-40 days. The sowing time varies in different regions and provinces. For example, in the north, spring comes later and winter comes earlier, so the best sowing period is generally from February to April. Autumn sowing is from July to August, while in the south, sowing can be done from January to April and from August to September. Be sure not to plant the seeds too deep; the best depth is 2-3 centimeters. More than 3 centimeters will affect the germination rate, so extra attention is needed.
5. French holly propagation method: The main propagation method of French holly is cutting propagation, but it can also be propagated by sowing. Choose an area with high terrain, thick soil layer, loose soil, and good drainage as the base. Remove weeds, level the high ridges to about 1 meter, and get rid of underground pests and harmful bacteria. After the seedbed is leveled, flatten it with a spade, pour rotten thin human waste, and then cover the bed surface with a layer of sifted coke ash or yellow soil.
Cutting propagation should be shallow, not deep. For small branch cuttings, the flat face should be downward, and for large branch cuttings, the depth is 1 centimeter into the upper middle of the next node. The cutting should be tilted at about 45 degrees to the ground. After cutting, press the soil around the cutting and water thoroughly to make the lower part of the cutting stick to the soil. When cutting, do not leave too many leaves on the cutting, nor should they be cut off completely. Depending on the size of the leaves, cut off 1/2 to 2/3 of each leaf to reduce excessive consumption of water and nutrients.
After cutting, a shed should be set up to provide shade, reducing transpiration and direct sunlight on the seedbed. In early spring or late autumn, a film should be added to prevent winter damage. After cutting, it is also necessary to water regularly to keep the seedbed soil moist, with the surface soil not showing white as a suitable method.
After cutting, top-dressing can be combined with watering, or phosphate potassium and urea can be used for foliar application. Weeding should be very careful not to collide with the cuttings. French holly has strong resistance to adversity, fewer diseases and pests, and occasionally infested with刺蛾 or aphids, which can be controlled by applying pesticides such as dichlorvos and pymetrozine.
【French Holly Maintenance Methods】
After cutting, a shed is required, and proper shading can help reduce some direct sunlight. If the season is early spring or late autumn, a film should be added to prevent winter damage. After cutting, it is also necessary to water appropriately to truly maintain the moisture of the seedbed soil, with the surface soil not showing white as a suitable method.
In daily management of French holly, it has relatively few diseases and pests, but there may still be some problems. Therefore, it is necessary to do a good job of applying pesticides and preventing diseases. After cutting, it usually takes about 25 days to start生根, and about 40 days for new buds to grow, with the seedling period being about three months. Below is a specific introduction to the disease and pest control methods of French holly.
French holly disease and pest control methods: After 2-3 years of cultivation in the nursery, French holly can be transplanted. Transplanting is best done in spring, requiring that the roots are not damaged when digging the seedlings and that they are transplanted with soil. When first planted, pay attention to weeding, water when dry, and strengthen management. Holly is prone to white wax scale insect damage, and sooty mold is likely to occur between dense branches and bark, so timely prevention and control are necessary.
