How tall can French holly grow in a year?
Let's talk about how tall French holly can grow in a year and the experience of maintaining and caring for green plants, including precautions for planting French holly. Next, the editor will introduce these topics.
French holly refers to the Japanese coral tree, not the type of holly we usually understand. Many people may not have much mastery of the planting techniques for French holly. Planting French holly at this time may affect its growth. If you can plant it using 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 planting techniques and maintenance methods for French holly.
【French Holly Planting Techniques】
1. Selection of French holly seeds: Choose seeds collected in the current year and preserved using scientific methods. Immature seeds should be avoided at all costs. Please take the selection of seeds seriously.
2. How to germinate French holly seeds: Without germination treatment, holly seeds often take a year to germinate. Remove the fruit skin, wash clean, and use moist sand at low temperatures for stratification to induce germination.
3. Soil for planting French holly: The soil should be disinfected and treated for pests. It is suitable for planting in moist and semi-shaded areas, preferring fertile soil to grow more vigorously.
4. Sowing method for French holly: French holly can be sown in autumn or winter, with sand storage for the following spring. It can germinate and grow into seedlings within 30~40 days after sowing. Due to different regions and provinces, sowing times vary. For example, in the north, the best sowing period is generally from February to April in spring, while in autumn, it is from July to August. In the south, sowing can be done from January to April and from August to September. Please note that the seeds should not be buried too deep, with the best depth being 2~3 centimeters. More than 3 centimeters will affect the germination rate, so be more careful.
5. Propagation methods for French holly: The main propagation method for French holly is cutting propagation, but it can also be propagated by seeding. Choose a high ground with thick soil layers, loose soil, and good drainage as the base. Remove weeds, level the ground to form high ridges about 1 meter tall, and remove underground pests and harmful bacteria. After the seedbed is leveled, use a spade to press it flat, pour rotten thin human manure, and then spread a layer of sifted cinder ash or yellow soil on the bed surface.
For cutting propagation, cuttings should be shallow rather than deep. For small branches, the cut face should be downward, and for large branches, the depth is 1 centimeter below the next node. The cutting should be倾斜 at about 45 degrees to the ground. After planting, 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 or remove all of them. 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 for shading to reduce transpiration and direct sunlight on the seedbed. In early spring or late autumn, a film should be added to prevent winter damage. After cutting, the seedbed should be watered frequently to keep the soil moist, with the surface soil not showing white as an indicator. Top-dressing for cutting seedlings can be combined with watering or foliar application with a mixture of phosphorus and potassium plus urea. Weeding should be done carefully to avoid bumping into 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 spraying pesticides such as敌敌良 or pyrethrin.
【French Holly Maintenance Methods】
After cutting, a shed is required and proper shading is necessary to reduce direct sunlight. If cutting in early spring or late autumn, a film should be added to prevent winter damage. After cutting, proper watering is necessary to maintain soil moisture in the seedbed, with the surface soil not showing white being a suitable method.
In regular management of French holly, the plant itself has relatively few diseases and pests, but problems can still arise. Therefore, it is necessary to do a good job of pesticide spraying and prevention. After cutting, the roots will start to grow in about 25 days, and new buds will appear in about 40 days, with the seedling period being about three months. Below is a detailed introduction to the pest and disease control methods for French holly.
French holly disease and pest control methods: After 2-3 years of cultivation in the nursery, French holly can be transplanted. Transplanting should be done in spring, ensuring that the roots are not damaged and the plants are transplanted with soil. Initial planting requires attention to weeding, watering during dry periods, and strengthening management. Holly is prone to white wax scale insects and sooty mold in dense branches and leaves, and prompt control measures should be taken.
