When to use potassium dihydrogen phosphate to promote flowering in Cymbidium
foliar application of potassium dihydrogen phosphate foliage fertilizer to Cymbidium is generally done on sunny evenings when the sun's rays cannot reach the leaves of the orchid. After spraying, attention should be paid to strengthening ventilation to keep the leaves dry within 1 hour. This is not only conducive to the absorption of (S-Y) components by the orchid plant at night but also avoids local fertilization damage caused by sunlight shining on the leaves. The interval for foliage fertilizer should be about 10-15 days to prevent excessive nutrition.
Actually, the main components of potassium dihydrogen phosphate are phosphorus and potassium elements, which are often used as flowering fertilizers for foliar application on orchids. The commonly used inorganic fertilizers for growing orchids mainly include potassium dihydrogen phosphate and urea.
Inorganic fertilizers contain different nutrients and have different effects on orchids, so it is necessary to pay attention to the combined application, especially the concentration should be light during application.
Cymbidium blooms in the summer and autumn seasons. After the Qingming Festival in April, it should be sprayed with foliage fertilizer to promote its bud differentiation.

When applying foliage fertilizer to Cymbidium, the spray head should be facing up, and the mist should be fine enough to ensure that both the front and back of the leaves can be sprayed.
Moreover, since the fertilizer is absorbed through the stomata on the leaves, and most of the stomata are distributed on the back of the leaves, more emphasis should be placed on spraying the back of the leaves, and it is best not to let the leaves drip to prevent fertilizer solution from accumulating at the leaf tips and causing tip burn.
In summary, foliar application of potassium dihydrogen phosphate fertilizer to Cymbidium should be done during the bud differentiation stage of the orchid. It is mainly suitable to spray in a mist form, and it is important not to let too much fertilizer accumulate at the leaf tips to avoid fertilizer burn and tip damage.
In addition, the next morning after fertilizing in the evening, the orchid should be sprayed with clean water once to wash away the remaining fertilizer on the leaves to prevent fertilizer damage caused by sunlight.
The introduction above about when to use potassium dihydrogen phosphate to promote flowering in Cymbidium is for everyone to learn and understand!
