Fertilizing orchids is a double-edged sword: only with rational fertilization can they be grown well

With little fertilizer, orchids grow steadily; with much fertilizer, orchids grow impetuously. With little fertilizer there is naturally less disease, and somewhat fewer new shoots, but it is safe, and for preserving rare varieties it is beneficial and harmless; with much fertilizer there is naturally more disease, requiring antibacterial drugs to balance it, and relatively more new shoots, with somewhat faster growth, which is beneficial for bulking up the plants and shortening the production cycle. The timing of fertilization is also an important factor. A safe fertilization method is to begin fertilizing only in late spring or after the Start of Summer, which can reduce the frequency of the first wave of warm-spring disease outbreaks, but the fertilizer supply for the orchids' growth needs falls somewhat short, and the sprouting time is relatively later; fertilizing in mid-spring helps to replenish nutrients in time and can advance sprouting, but it is necessary to prevent the first ferocious wave of spring disease outbreaks, so early fertilization requires applying medicated fertilizer within one or two days after fertilizing to preemptively control the occurrence of disease. After absorbing nutrients, theorchid plantsbegin to accelerate their growth; during the accelerated growth period their resistance is somewhat reduced, so drugs are needed for prevention, yet using too much medication will also affect theorchid plants'resistance and growth. Fertilization must be suited to the specific problem, and it requires experience accumulated in ordinary practice to perfect. Therefore beginners should use light fertilizer, while experts should use more fertilizer.
