Wen Xinlan's conservation methods

Oncidium, like most orchids, prefers higher air humidity, but because of the large differences in plant species of the different species, the resistance to drought is also different. Without pseudo-bulb varieties, the ability to resist drought is poor, so we must always keep the matrix in the basin moist and add moisture to the substrate.

Decreasing moisture in the winter is beneficial to flowering, and watering should be stopped when the temperature is 10°C. In the hot summer season, water should be sprayed on the ground, pedestals, roads and plants around the plants to increase the air humidity, otherwise it will affect its growth.

At the same time, because of the hot summer weather, the cultivation of Oncidium in the greenhouse in addition to maintaining relatively high humidity, but also to maintain good ventilation, ventilation, or poor growth, but also prone to rot. Appropriate fertilization is an effective measure for the growth of Oncidium robustness. When planting, use a small amount of slow-release fertilizer as the base fertilizer, apply once a month cooked bean cake water, oil moromi, bone meal and so on.

In addition to the low temperature in late autumn and winter, in the spring, summer, early autumn and spring season, a 1500 to 2000 times liquid water-soluble fast-acting fertilizer is applied every 2 to 3 weeks. When the flower is not blooming, the three elements of nitrogen, phosphorus, and potassium are balanced. The compound fertilizer can be foliar sprayed and can also be applied at the root. Phosphorus and potassium fertilizers should be added when near flowering.
