What are the latest points to note when planting Forsythia?
Forsythia is a deciduous shrub of the Dicotyledon class, with high ornamental value; it is also a commonly used Chinese medicinal herb, and moreover it is an oil-bearing plant, with an oil content of more than 25 percent. Of course, it can also be used to make preservatives, making a great contribution to keeping food fresh. So do you know what needs attention when planting this plant? Today, let us take you through the points to note when planting Forsythia.
1. Planting soil
Forsythia planting does not have high requirements for soil, but to improve the economic benefits of Forsythia, we usually choose sandy loam that is fertile, has a complete soil structure, good drainage and strong permeability, preferably soil mixed with sand; if there is none, an appropriate amount of river sand can be added and mixed evenly during artificial land preparation. Finally, the planting site should have abundant water resources nearby and some surrounding shade, preferably a semi-sunny gentle slope.
2. Planting methods
The planting method is also something worth noting. There are four planting methods for Forsythia, namely seed propagation, layering propagation, cutting propagation and division propagation. Different propagation methods have certain deviations in planting time, but basically the best planting is in spring; however, seed propagation is generally sown at the end of May, division is in autumn and winter or early spring, layering is in spring, and cutting is around the end of April in spring. Next, when using different planting methods, we must understand its planting process to avoid errors that affect the survival rate of planting.
3. Shaping and pruning
During the growth of Forsythia, branch and leaf pruning is needed. Generally, it is done only when Forsythia has grown to about 80 to 90 cm. When pruning, the main focus is top pruning, which can promote the growth of lateral branches and improve the yield and quality of Forsythia. When pruning, old branches, dead branches, diseased and pest-infested branches, and dense branches also need to be reasonably pruned to avoid nutrient loss.
4. Water and fertilizer management
The entire growth period of Forsythia requires a sufficient nutrient supply. Generally, at the seedling stage, we topdress according to the principle of frequent application of thin fertilizer, mainly using decomposed farmyard manure. Later, it needs to be done according to the growth needs of Forsythia. The fertilizer types remain unchanged, but appropriate additional application of wood ash, phosphate fertilizer, cake fertilizer and urea, etc., is needed to promote the growth of Forsythia and ensure its yield and quality. Of course, during its growth we also need to pay attention to the water supply, watering promptly in dry seasons to keep the soil moist, while in the rainy season drainage is needed to avoid water accumulation, which can cause root rot and directly affect the yield of Forsythia.
5. Light conditions
Forsythia has a relatively large demand for light. It is a light-loving plant and will grow more vigorously in an environment with direct sunlight, but if there are local shaded areas, it can also grow very well. What we need to note is that Forsythia must never be allowed to grow in a completely dark environment, because if there is insufficient light, it will cause poor growth of Forsythia and even wilting.
Forsythia has relatively strong adaptability to the environment and also has a certain cold tolerance, and can grow normally even at winter temperatures. However, in the process of planting, in addition to the above points to note, we also need to pay attention to the prevention and control of its diseases and pests. We believe that as long as we master these points well, the Forsythia we plant will surely satisfy everyone greatly.
