Its demand for fertilizer is relatively large. Moreover, different kinds need to be used in different periods of time. To fertilize it correctly and scientifically can promote its healthy and healthy growth.
(1) first, introduce some basic fertilizers. At the beginning of spring, when the soil is just thawing, and at the beginning of autumn, the base fertilizer should be applied. The organic flower fertilizer is mixed with the fertilizer containing N, P and K, and is applied in one piece.
(2) the use of chemical fertilizer. This aspect mainly concentrates in three periods, namely the plant's budding period (generally at the beginning of March), the sclerotic period (probably in the middle of May) and the fruit expanding period.
(3) in addition, if the early defoliation of the previous year is serious, or the load of the plant is particularly large, then it is necessary to apply fertilizer outside the root. The main application is urea and so on.
(4) in another case, many leaves of the previous year have turned white, or many branches have dried up, then some (CuSO4) solution can be used to remedy it. However, if the organic fertilizer used is animal manure, then the solution can also be used
(1) different varieties have different fertilization time. So precocious topdressing time should also be earlier; those who mature later naturally should be later.
(2) like many other plants, the amount of fertilizer should not be too much, which can be determined by the size of the plant.
