How tall can French holly grow in a year
A comprehensive explanation of how tall French holly can grow in a year and knowledge about the cultivation and maintenance techniques of French holly in the field of flowers. Let's get to know together.
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. The following is an introduction to the planting and maintenance methods of French holly by the 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. Only this is the premise. Do not use unripe 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 holly seeds are not germinated, they often take a year to germinate. Remove the fruit skin, wash clean, and use wet sand and low-temperature stratification to treat the seeds for germination.
3. Soil for planting French holly: The soil should be disinfected and pest-eliminated first. It is suitable for planting in moist and semi-shady places and prefers fertile soil to grow more vigorously.
4. French holly sowing method: French holly can be sown in autumn or winter sand storage for the following spring. After sowing, seeds 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, with the best sowing period generally from February to April in spring, and from July to August in autumn. In the south, sowing can be done from January to April or from August to September. Be sure not to bury the seeds too deep, with the best depth being 2-3 centimeters. More than 3 centimeters will affect the germination rate and require attention.
5. French holly propagation methods: Propagation of French holly mainly involves cutting, but it can also be propagated by sowing. Choose a high and fertile area with 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, level the seedbed, flatten it with a spade, apply dilute human manure urine, and then cover the bed surface with a layer of sifted cinder ash or yellow soil.
For cutting propagation, it is better to cut shallow rather than deep. Small branches are cut with the flat side down, and large branches are inserted 1 centimeter into the upper middle of the next internode, with the cutting slope about 45 degrees. 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 them all. Depending on the size of the leaves, cut off 1/2 to 2/3 to reduce excessive consumption of water and nutrients.
After cutting, a shed should be set up to provide shade and 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, the seedbed should be watered regularly to keep the soil moist, with the surface soil not showing white being suitable. Fertilization of cutting seedlings can be combined with watering, or foliar application of phosphorus and potassium mixed with urea can be used. Weeding should be very careful not to bump into the cuttings. French holly has strong stress resistance and few diseases and pests. Occasionally, there may be caterpillar or aphid infestations, which can be controlled by spraying pesticides such as diafenthiuron or pymetrozine.
【French Holly Maintenance Methods】
After cutting, a shed should be set up and appropriate shading should be provided 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 should be carried out to keep the seedbed soil moist, 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 issues. Therefore, everyone needs to do a good job of pesticide spraying and prevention. After cutting, it usually takes about 25 days for the roots to start growing, about 40 days for new buds to grow, and the seedling period is about three months. The following are the specific methods for controlling diseases and pests of French holly.
French holly disease and pest control methods: After 2-3 years of cultivation in the nursery, French holly can be transplanted and planted. Transplanting should be done in spring, and care should be taken not to damage the roots when digging the seedlings and to transplant them with soil. Attention should be paid to weeding and watering when dry, and management should be strengthened. French holly is susceptible to white wax scale insect damage, and sooty mold can easily occur between dense branches and charred skin, so timely prevention and control should be carried out.
The above is the specific content of how tall French holly can grow in a year and the planting and maintenance techniques of French holly for everyone's reference and operation.
