When is Chinese rose suitable for fertilization?

There are different opinions about the fertilization of Chinese rose. There are several principles to judge right and wrong: apply fertilizer in early spring and save fertilizer in winter. Some people think that the biological fertilizer for winter festival, that is, farm poultry fertilizer, can be beneficial to the overall nutritional supplement of rose in the next year after being sterilized at low temperature in winter. Of course, many flower friends have their own profiles on what fertilizers to apply, such as high phosphate fertilizer, such as potassium dihydrogen phosphate and other targeted fertilizers. This article is only aimed at novice flower lovers, because novice flower lovers have a natural fear of overly complicated plans.

Generally, deep digging and fertilization should be carried out around the rose seedlings, and it is best to ferment biological fertilizer to avoid damaging the root system. Shrub roses can choose fertilization distance according to crown width. Generally, it is enough to fertilize in the same place as the crown width of roses, but it is not easy to choose vines. When the general biological fertilizer is effective, it is enough to fertilize about 25 minutes from the plant10-0.

As for spring fertilizers, most of them are chemical fertilizers and compound fertilizers, which have quick results. Some flower lovers use urea mainly for the rapid growth of Chinese rose plants, but more flower lovers use compound fertilizer. The special controlled release fertilizer for flowers contains three elements: nitrogen, phosphorus and potassium, and the total amount can be determined according to the plant size.

Controlled release fertilizer is not easy to damage roots, and topdressing also has a slow effect. When the Chinese rose seedlings are strong enough, irrigate the roots with potassium dihydrogen phosphate or apply it to the leaves. Potassium dihydrogen phosphate itself belongs to foliar fertilizer, but it can also be used to irrigate roots, which can promote flower bud differentiation and supplement the nutrition of blooming rose.

Fertilization, and after autumn pruning, spring pruning can be supplemented by fertilization, which can make the pruned roses quickly return to lush. If the roses are not fertilized regularly, it is easy to cause fertilizer damage and affect the normal growth of roses. Fertilize twice a year and you can't be greedy. Summer is in the high temperature period, so it is forbidden to fertilize the dormant rose to avoid plant death.

I hope my answer can help all flower friends.
