How should the fertilizing schedule be arranged? A detailed explanation of key fertilizing points

After the potted orchids are brought out of their winter quarters in early spring, around the time of "Qingming" (Tomb-Sweeping Day), choose a day with clear and mild weather, and first, for those without flower buds,orchidsapply fertilizer once, mainly a dilute one. After an interval of more than half a month, apply it once again. For any that haveflowered, wait more than ten days before fertilizing. If repotting and changing the soil, place some decomposed sediment at the bottom of the pot, then add a layer of soil and plant the root system seated on it, so that no further fertilizing is needed that year. During the period when young shoots and new roots are sprouting, more nutrients are required; if appropriate fertilizing is not given, the shoots that later break through the soil and the newly unfurled leaves will become thin and weak, and it will be hard for them to bloom, or the growth and flower size of the following year will be affected. Entering the plum rain season, the daughter plants grow very fast, breaking through the soil one after another, new roots multiply, and flower buds germinate along with them; at this time, fertilize once or twice on clear days, with more than ten days between each application. At Minor Heat, if theorchid plantsare thin and weak, apply one more dose of dilute fertilizer. During the period from White Dew to the Autumn Equinox, since the new leaves have mostly grown and the flower buds have all their layers of sheaths complete, a final dose of dilute fertilizer may be applied at this time, but it must be more dilute and smaller in amount than before. Fertilizing should be done in the morning or evening. If the surface soil in the pot is slightly compact, first use a blunt-edged bamboo strip to carefully and gently loosen it along the rim of the pot, and by no means injure the orchid roots. If the leaves are thin in texture and pale in color, this is a sign of fertilizer deficiency, and the number of supplemental fertilizings or the concentration may be appropriately increased. When fertilizing, the principles are small amounts, dilution, frequent application, and doing it at the right time.
