In fact, it is not impossible to use compound fertilizer when fertilizing rose flowers, but not all compound fertilizers can fertilize rose flowers. Generally, the compound fertilizer suitable for rose flower is n, P, K compound fertilizer.
Generally, the concentration of compound fertilizer is very high. If you are not careful when using it, it will easily lead to burning roots. This is also the case when applying compound fertilizer to rose flowers. The disadvantages of concentration and elements are very important. Generally, the ratio of nitrogen, phosphorus and potassium should be the same
When using compound fertilizer for rose flowers, people always worry that too much concentration will hurt the roots. In fact, this is mainly caused by excessive use, or when fertilization is directly buried in the soil, but also very shallow.
In fact, adding water is a good way. For example, with a 500ml plastic bottle, it can be mixed with half a bottle cap as much compound fertilizer.
However, because when we raise flowers, our conditions and cultivation forms are different, and the nutrients we need are different, so we should make changes according to the actual situation when we apply fertilizer.
Note that when spraying wet compound fertilizer on rose flowers, do not spray it on plants and leaves.
