What should be noted when planting Forsythia suspensa? A full analysis of cultivation key points
Forsythia suspensa is a deciduous shrub of the class Dicotyledoneae, with high ornamental value, and it is also a commonly used Chinese medicinal herb, and it is even 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 food preservation. So do you know what should be noted when planting this plant? Today, the editor will take you to look at the precautions for planting Forsythia suspensa.
1. Planting soil
Forsythia suspensa does not have high requirements for soil, but in order to improve its economic benefits, we usually choose sandy loam with fertile soil, complete soil structure, good drainage and strong permeability, preferably sandy soil; if there is none, an appropriate amount of river sand can be added and mixed evenly during artificial soil 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 methods are also worth our attention. There are four planting methods for Forsythia suspensa, namely seed propagation, layering propagation, cutting propagation and division propagation. Different propagation methods have certain deviations in planting time, but basically the best planting time 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. Secondly, when we adopt different planting methods, we must understand their planting process to avoid errors that affect the survival rate of planting.
3. Shaping and pruning
During the growth of Forsythia suspensa, branch and leaf pruning is needed. Generally, it is carried out only when Forsythia suspensa has grown to about eighty or ninety cm. When pruning, the main focus is pruning the top, which can promote the growth of side branches and improve the yield and quality of Forsythia suspensa. When pruning, it is also necessary to reasonably prune old branches, dead branches, diseased and pest-infested branches, and dense branches to avoid nutrient loss.
4. Water and fertilizer management
The entire growth period of Forsythia suspensa requires sufficient nutrient supply. Generally, at the seedling stage, we apply topdressing according to the principle of frequent application of thin fertilizer, mainly based on decomposed farmyard manure. Later, it needs to be carried out according to the growth needs of Forsythia suspensa. The fertilizer types remain unchanged, but it is necessary to appropriately increase the application of wood ash, phosphate fertilizer, cake fertilizer and urea, etc., so as to promote the growth of Forsythia suspensa and ensure its yield and quality. Of course, during its growth process, we also need to pay attention to water supply, watering timely in dry seasons to keep the soil moist, while in the rainy season drainage is needed to avoid water accumulation, which causes root rot and directly affects the yield of Forsythia suspensa.
5. Light conditions
Forsythia suspensa has a relatively large demand for light. It is a light-loving plant and will grow more vigorously in direct sunlight, but if there is partial shade, it can also grow very well. What we need to note is that Forsythia suspensa must never be allowed to grow in a completely dark environment. If there is insufficient light, it will cause poor growth and even wilting.
Forsythia suspensa still has strong adaptability to the environment, and it also has a certain cold resistance, and can grow normally even at winter temperatures. However, in the planting process, in addition to the above points that need attention, we also need to pay attention to the prevention and control of its diseases and insect pests. We believe that as long as we master these points well, the Forsythia suspensa we plant will certainly satisfy everyone.
