How to fertilize Phalaenopsis orchids
A little knowledge to share with you on how to fertilize Phalaenopsis orchids in green plant flower planting. Let's learn about it together next.
Fertilizing Phalaenopsis orchids, fertilizers are generally divided into two major categories: solid fertilizers and liquid fertilizers. Currently, the solid fertilizers used are mostly directly applied to the pot after the fermentation of farmyard manure, slowly absorbed by the roots, with long-term fertilizer effect, and less likely to cause fertilizer damage as long as the amount applied is not too large. The most commonly used and convenient to use is liquid fertilizer combined with watering. Common ones include chemical fertilizers and fertilizer water fermented with farmyard manure.
Phalaenopsis orchids grow rapidly, and their fertilizer requirement is slightly higher than that of general orchids, but the principle should still be to apply less fertilizer and use diluted fertilizers.
In spring, only a small amount of fertilizer can be applied. Fertilization is completely stopped during the flowering period. After the flowering period, when new roots and buds start to grow, liquid fertilizer is applied once a week, sprayed on the leaves and potting medium. The application concentration is 1,000 to 2,000 times liquid. When new leaves have grown and entered the vigorous growth stage, a small amount of solid farmyard manure can be applied on the pot surface to provide sufficient nutrients. No fertilizer should be applied when new roots have not grown after potting, and only after about one month can some diluted liquid fertilizers be applied.
Summer is the season of vigorous growth for Phalaenopsis orchids, and continuous fertilization should be carried out, applying liquid fertilizer once a week. In the hot and humid summer nights in the south, it is not conducive to the growth of Phalaenopsis orchids, and the plant growth momentum weakens. Fertilization is not beneficial to the plant, so it is best to stop fertilizing for a period of time. In the late autumn, plant growth slows down, and fertilization should be reduced. Too much fertilization often causes excessive plant growth, affecting the formation of flower buds, and resulting in the inability to bloom later. Fertilization can be stopped by the end of October, and in winter, plants basically stop growing. Fertilizing a plant that has stopped growing can cause root rot.
Additionally, in terms of the proportion of nitrogen, phosphorus, and potassium in fertilizers, high-nitrogen fertilizers should be applied during the seedling stage and the period of vigorous growth; during the flower bud formation stage to the flowering period, fertilizers with a high proportion of phosphorus and potassium should be applied. That is all the introduction on how to fertilize Phalaenopsis orchids.
The specific introduction shared above on how to fertilize Phalaenopsis orchids is hoped to bring some floral knowledge to orchid enthusiasts.
