The planting and maintenance of French holly
The editor introduces you to the planting and maintenance of French holly and teaches you the correct methods for maintaining French holly in terms of plant knowledge, followed by a comprehensive introduction.
French holly refers to the Japanese coral tree, not the type of holly we understand. Regarding the planting technology of French holly, many people may not have much mastery of the planting technology of French holly. If you start planting French holly at this time, it may affect the growth of French holly. If you can plant it according to scientific methods, it may reduce various problems, and the survival rate of French holly will relatively be higher. Below, China Landscape Network provides a detailed introduction to the planting technology and maintenance methods of French holly.
【French Holly Planting Technology】
1. Selection of French holly seeds: Choose seeds collected in the same year and preserved by scientific methods. Only then can everything else follow. Do not use immature seeds, or no matter how hard you try to plant them later, please choose seeds carefully.
2. How to germinate and awaken French holly seeds: If the seeds of holly are not treated for germination, they often take a year to germinate. Rub off the fruit skin, wash clean, and treat the seeds with moist sand at low temperature for stratification to induce germination.
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 stored in sand in winter and sown in the following spring. After sowing, it can germinate and grow into seedlings within 30-40 days. Due to different regions and provinces, sowing times also vary. For example, in the north, spring comes later and winter comes earlier, with the best sowing period usually from February to April for spring sowing, and from July to August for autumn sowing, while in the south, sowing can be done from January to April or from August to September. Be sure not to plant the seeds too deep, the best depth is 2-3 centimeters, and deeper 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 sowing. Choose a high ground with thick soil layer, loose soil, and good drainage as the base. Remove weeds, level the ground to form high ridges about 1 meter tall, remove underground pests and harmful bacteria. After leveling the seedbed, flatten it with a spade, pour diluted decomposed human waste, and then spread a layer of sieved brick ash or yellow soil on the bed surface.
Cutting propagation should be shallow rather than deep, with small branches cut horizontally facing downward, and the depth of large branch cuttings should be inserted into the upper middle 1 centimeter. The cutting should be tilted at about a 45-degree angle to the ground, and after cutting, press the soil around the cutting and water it 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 you cut off all of them. Depending on the size of the leaves, cut each leaf by 1/2 to 2/3 to reduce excessive consumption of water and nutrients.
After cutting, it is necessary to build a shed 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, it is also necessary to water regularly to keep the soil of the seedbed moist, with the surface soil not showing white as an appropriate method.
Top dressing for cutting seedlings can be combined with watering, or foliar application of phosphorus potassium and urea can be used. Weeding should be very careful not to bump into the cuttings. French holly has strong resistance to adversity, few diseases and pests, and occasionally affected by刺蛾 or aphids, which can be controlled by喷杀 with pesticides such as敌敌良 or 吡虫啉.
【French Holly Maintenance Methods】
After cutting, it is necessary to build a shed and provide appropriate shading 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 properly 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, the plant itself has relatively few diseases and pests, but problems can still occur. Therefore, it is necessary to do a good job of pesticide spraying and prevention. After cutting propagation, it usually takes about 25 days to start rooting and about 40 days for new buds to grow, with the seedling period being about three months. Below is a detailed introduction to the disease and pest control methods of French holly.
Methods for controlling diseases and pests of French holly: After 2-3 years of cultivation in the nursery, French holly can be transplanted. Transplantation should be done in spring, requiring that the roots are not damaged when digging the seedlings, and that they are transplanted with soil. Initially, attention should be paid to weeding, watering when dry, and strengthening management. Holly is easily affected by white wax scale insects, and dense branches and leaves as well as charred skin are prone to sooty mold, so it is important to prevent and treat them in time.
