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. The following is a detailed introduction of the planting techniques and maintenance methods of French holly by China Landscape Network.
【French Holly Planting Techniques】
1. Selection of French holly seeds: Choose seeds collected in the current year and preserved with scientific methods. Immature seeds should not be used, or else no matter how hard you try to plant them later, please select seeds carefully.
2. How to germinate French holly seeds: If the holly seeds are not germinated, they often take a year to germinate. Remove the fruit skin, wash clean, and use wet sand at low temperature for stratification to germinate the seeds.
3. Soil for planting French holly: The soil should be disinfected and treated for pest control, suitable for planting in moist semi-shaded areas, and prefers fertile soil to grow more vigorously.
4. Sowing method of French holly: French holly can be sown in autumn or winter sand storage the following spring. After sowing, it can germinate and grow into seedlings within 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. In autumn, it is from July to August, while in the south, it can be sown from January to April or from August to September. Be sure not to bury the seeds too deep, the best depth is 2-3 centimeters, and more than 3 centimeters will affect the germination rate, so be more careful.
5. Propagation methods of French holly: The main propagation method of French holly is cutting propagation, but it can also be propagated by seeds. Choose a high ground with deep soil layer, loose soil, and good drainage as the base. Remove weeds, level the ground to form high ridges of about 1 meter, remove underground pests and harmful bacteria, level the seedbed, flatten it with a spade, pour diluted human manure, and then cover the bed surface with a layer of sifted coke ash or yellow soil.
For cutting propagation, the cuttings should be shallow rather than deep. The cutting face of small branch cuttings should be downward, and the depth of large branch cuttings should be the next internode inserted into the upper middle by 1 centimeter. The cutting should be倾斜 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, the leaves on the cutting should not be left too many, 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, it is necessary to set up a shed for shading to reduce evaporation 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 frequently to keep the seedbed soil moist, with the surface soil not showing white as the appropriate method. Topdressing for cutting seedlings can be combined with watering or foliar application with phosphorus acid potassium and urea. Weeding should be very careful not to collide with the cuttings. French holly has strong resistance to adversity, few diseases and pests, and occasional occurrences of刺蛾 or aphids can be controlled by喷洒 pesticides such as敌敌畏 or pymetrozine.
【French Holly Maintenance Methods】
After cutting, a shed should be set up and properly shaded to 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 more suitable method.
In daily management of French holly, the plants have relatively few diseases and pests, but problems can still occur. Therefore, it is necessary to do a good job of pesticide spraying and prevention. Usually, about 25 days after cutting, the roots will start to grow, and new buds will grow in about 40 days, with the seedling period being about three months. The following 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, it can be transplanted. Transplantation should be carried out in spring, requiring the roots not to be damaged when digging and移植 with soil. At the beginning, pay attention to weeding and watering 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 should be carried out.
The above introduction on how to make French holly grow fast and the comprehensive methods of understanding the planting and maintenance techniques of holly, I hope it can solve your problems with green plants.
