What problems should be paid attention to in Forsythia suspensa planting?

Forsythia suspensa is a deciduous shrub of Gemini class, which has high ornamental value. At the same time, it is also a commonly used traditional Chinese medicine, and it is a kind of plant oil with oil content of more than 25%. Of course, it can also be used to make preservatives, and it has also made a great contribution to food preservation. So do you know what you need to pay attention to when planting this plant? Today, the editor will take you to take a look at the notes for the planting of Forsythia suspensa.

1. Planting soil

The requirement of forsythia planting on soil is not high, but in order to improve the economic benefit of Forsythia suspensa, we usually choose sandy loam with fertile soil, complete soil structure, good drainage and strong permeability, preferably sandy soil. if there is no artificial soil preparation, an appropriate amount of river sand can be added to mix well. Finally, it is rich in water resources near the planting site, and there is a certain shelter around it, preferably a gentle slope of half the sun.

2. Planting method

The method of planting is also worthy of our attention. There are four planting methods of Forsythia suspensa, which are seed propagation, striping propagation, cutting propagation and split propagation. Then there is a certain deviation in the planting time of different breeding methods, but basically the best planting is in spring, but seed propagation is generally sown at the end of May, split is in autumn, winter or early spring, pressing is in spring, and cutting is around the end of April in spring. The second is that when we use different planting methods, we should understand its planting process to avoid errors and affect the survival rate of planting.

3. Shaping and pruning

Pruning branches and leaves is needed in the growth process of Forsythia suspensa. Generally speaking, it is necessary to wait until Forsythia suspensa grows to about 80 or 90 centimeters. Pruning is mainly at the top, which can promote the growth of side branches of Forsythia suspensa and improve the yield and quality of Forsythia suspensa. When pruning, old branches, withered branches, disease and insect branches, dense branches and other reasonable pruning are needed to avoid the loss of nutrients.

4. Water and fertilizer management

Forsythia needs an adequate supply of nutrients throughout its growing period. Generally, in the seedling stage, we apply fertilizer according to the principle of frequently applying thin fertilizer, mainly rotten farm manure. In the later stage, it needs to be carried out according to the growth needs of Forsythia suspensa, the fertilizer species of fertilization remain unchanged, but appropriate application of wood ash, phosphate fertilizer, cake fertilizer and urea is needed to promote the growth of Forsythia suspensa and ensure the yield and quality of Forsythia suspensa. Of course, in the process of its growth, we also need to pay attention to the supply of water, timely watering in the dry season to keep the soil moist, and drainage in the rainy season to avoid stagnant water and cause root rot, which directly affects the yield of Forsythia suspensa.

5. Lighting conditions

Forsythia has a great demand for light, it is a kind of light-loving plant, it will grow more exuberantly in the direct sunlight environment, but if there is a local shade zone, it can also grow well. What we should pay attention to is that Forsythia suspensa must not be allowed to grow in a completely dark environment. If there is not enough light, it will cause Forsythia suspensa to grow poorly or even wither.

Forsythia suspensa has a strong adaptability to the environment, but also has a certain cold resistance, and it can grow normally in winter temperature. However, in the process of planting, in addition to the above points, we should also pay attention to the prevention and control of its diseases and insect pests. I believe that as long as we master these points, the planting of Forsythia suspensa will make everyone very satisfied.
