Beware of fertilizer damage of granular plant materials

It was thought that the granular plant material was hydrophobic and could be applied boldly and relieved. The author used to apply thin chemical fertilizer solution once a week. The effect was quite good in the first year, but then it became more and more wrong, and in the end, a large number of people died. Trace the cause of death, begin to suspect what orchid disease, and finally know that the culprit is granular plant material.

Although the granular plant does not accumulate water, part of the fertilizer and water is absorbed by the particles in fertilization, and the drier the particles are, the more they are absorbed. After the fertilizer and water is absorbed by the particles, as the water evaporates, the fertilizer and water is reduced to fertilizer and stored in the particles. Fertilize again and again, accumulate again and again. As a result, the granular plant is almost turned into granular fertilizer, resulting in the death of a large number of bluegrass.

This kind of situation mostly occurs in the balcony orchid cultivation and indoor orchid cultivation, the number of pots is less, watering with sprayers, the particles will stop when they are wet, and the remaining fertilizer in the basin can not be eliminated. This rarely happens in large area orchid cultivation, because the method of flooding orchid is used to wash away the remaining fertilizer in the basin. In spite of this, it is hard to avoid the disadvantages of accumulation. Therefore, the granule old material can not be reused immediately. It should be soaked in clean water for a week and changed several times in the middle. The old material that has been treated in this way will be safe.
