1、 Management of seedling stage

For Forsythia suspensa propagated with seeds, weeding, soil loosening and thinning shall be carried out in time when the seedlings grow to 20 cm. When thinning seedlings, it is required to leave two plants in each hole and water them in time. When the seedlings grow to 30-40 cm, human urine manure should be applied once. During the growth period, fertilizer should be applied once or twice in combination with loose soil. It is best to apply farmyard fertilizer and phosphorus and potassium fertilizer to promote early maturity and more results

2、 Management of adult trees

During the management of adult trees, attention should be paid to pruning in time to cut off part of the bare branches and old branches, so as to facilitate the germination of new branches. After falling leaves every autumn, the over dense and withered branches should be cut off. As a result, the branches for many years should be cut short. At ordinary times, it is found that there are bare branches cut directly from the base to save nutrient consumption

3、 Management of wild trees

We should also pay attention to the management of wild forsythia and often carry out reclamation treatment, so that the yield increase effect will be more obvious. If there are contiguous adult trees, the slope shall be cleared at the end of spring and the beginning of autumn every year. During the growth period, soil loosening and fertilization shall be carried out to ensure better growth, promote multi fruit and improve yield. In addition, pruning should also be carried out after falling leaves at the end of autumn every year
