Orchids drop buds due to improper potting soil, so keep the potting soil loose and breathable, which will help the plant roots to fully absorb and grow. The pots can be changed once every breeding period. The soil should be loose, breathable and well-drained sandy loam.
Orchids lose flower buds due to improper lighting. During the spring and autumn growing seasons, they can receive 6-8 hours of light. In summer, they should be placed in a semi-shady and ventilated environment. In winter, they can receive daytime light to allow them to grow more fully.
Orchids require an appropriate amount of fertilizer to grow. If too much fertilizer is applied each time, fertilizer damage will occur and the flower buds will fall off. Therefore, fertilization must be carried out reasonably. Spray decomposed thin cake fertilizer water once every half month during the growth period. During the flower bud period, 0.2% potassium dihydrogen phosphate can be applied 1-2 times.
Long-term severe water accumulation or drought in the pot soil will cause the flower buds to fall off. Therefore, watering must be done reasonably, and the pot soil must be kept moist during the bud stage. Water once every 3-4 days, and be careful not to accumulate water to avoid root rot.
