What fertilizer does wild rose need?

The fertilizers needed by Rosa davurica are NPK organic fertilizer, compost and cake fertilizer.

The demand for fertilizer in different periods of Rosa davurica is different, so fertilization should be carried out according to the needs of plants. In the spring of March, before the roses begin to sprout and spread their leaves, apply organic fertilizers of nitrogen, phosphorus and potassium to make the branches strong and leafy. Every April-June, September-65438+1October is the vigorous growth period of roses, and nitrogen, phosphorus and potassium organic fertilizers and compost are applied once a week.

From flower bud differentiation to bud pregnancy, cake fertilizer should be applied, and phosphorus and potassium fertilizer can also be applied appropriately, such as spraying 0.2% potassium dihydrogen phosphate on leaves and topdressing outside roots. Rose is afraid of heat, and it is close to semi-dormancy in the high temperature period (the temperature is above 30℃) from July to August every year, so it is not suitable to topdress or apply less fertilizer.

Fertilization should be stopped at the end of autumn, so as not to promote autumn shoots and lead to freezing in winter. In winter, high concentration cake fertilizer can be applied at one time, and no topdressing is needed during the whole winter dormancy period.

Fertilization time:

Generally, Rosa multiflora is planted in autumn from defoliation to freezing. Organic fertilizer and calcium superphosphate should be applied immediately after planting, which can be mixed with soil and applied centrally. At the same time, irrigation should be timely.

Wild roses like big fat, but wild roses need to be fertilized according to the method of "thin fat and diligent application" With the growth of Rosa davurica, more and more flowers bloom and more nutrients are needed. At this time, the frequency and amount of fertilization should be increased to adapt to its growth law.

Every winter, the wild rose should be cultivated and fertilized at least once, so as to ensure that the tender branches and flower buds in the wild rose body have enough nutrition, and the wild rose will have more lush branches and leaves and more gorgeous flowers.

In the flower season, the frequency of fertilization should be changed to once or twice a week, so as to ensure the yield of flowers. At the same time, attention should be paid to cultivating the mother branches of flower picking and cutting off the buds on the twigs.
