How on earth should we use quick-acting fertilizer and slow-release fertilizer for rose?

Quick-acting fertilizer contains a lot of salt, and too much salt will actually cause some damage to the plant, so it is not to say that the more the better. Some flower lovers may be eager to dress and think that if I give a lot of fertilizer to the rose at one time, it can bloom a lot of flowers.

Believe me, this is undoubtedly uprooting seedlings to encourage, not only will you not see a large area of flowers blooming, or a wave of buds that have already appeared, but they may wilt off because you have applied a large amount of quick-acting fertilizer, and then it will be too late for you to cry.

No matter how fast the effect is, no matter how good the fertilizer is, we should adhere to the principle of moderate amount, within the range that the plant itself can bear. For example, although a large number of flowers are blooming now, another batch of buds are emerging at the same time. At this time, not only the blooming flowers need nutrition, but also give some stamina to those emerging buds before they can bloom.

In this case, the frequency of fertilization can be slightly diligent and certain, but the amount can still not be excessive each time. In fact, even if you give too much, the absorptive capacity of the root system is certain, which not only wastes fertilizer, but also harms the root system. And do not continuously fertilize many times, at most two times on the line, and then pour clear water, let the water will drain the fertilizer residue.

The time of slow-release fertilizer varies from three months to nine months, which can be selected according to the size of flowerpots and plants. generally speaking, the shorter the time, the faster the effect of slow-release fertilizer. The longer the time, the slower the effect. In other words, the fertilizer effect of three months of slow-release fertilizer is more obvious than that of nine months.

Therefore, the choice can be made according to the actual situation, but it should be noted that fertilization would rather be given less, more diligently, and not excessive at one time. In fact, it is not recommended to slow down the release of fertilizer at the bottom of the flowerpot, because when the temperature rises and the root system is relatively young, it is easy to be overnourished and burn out the root system.
