Fertilizer is used to raise orchids. Fertilizer is a double-edged sword.

Fei Shaolan is gentle, Fei Duolan is anxious. Less fertilizer, less natural diseases, relatively less germination, but safe, beneficial but harmless to the conservation of rare varieties; more natural diseases, which need to be balanced with antibiotics, sprouting relatively more and growing faster, which is beneficial to the growth of grass to speed up the production cycle.

The timing of fertilization is also an important factor. The safe fertilization method is to start fertilization in late spring or after the Beginning of Summer, which can reduce the frequency of disease and bacteria in the first wave of spring warmth, but the fertility needed for orchid growth is in short supply, and the budding time is relatively late. Fertilization in mid-spring is beneficial to replenish nutrients in time, and budding can be advanced, but it is necessary to prevent the first wave of ferocious bacterial damage in spring, so early fertilization should be applied within one or two days after fertilization to pre-control the occurrence of bacterial damage.

After absorbing fertilizer, bluegrass began to accelerate its growth, and its resistance decreased during the accelerated growth period, so drugs were needed to prevent it. More drugs will also affect the resistance and growth of bluegrass.

The use of fertilizer should prescribe the right medicine to the case, and it needs the accumulated experience to perfect it. Therefore, the novice should be light and fat, the master should be more fat.
