Many different fertilization methods for orchids
The editor will tell you about some knowledge of orchids and other flowers. The varieties of orchids are diverse and require different fertilization methods. Please see the detailed introduction below.
Orchids belong to tropical and subtropical epiphytic plants and are currently popular indoor high-grade ornamental flowers worldwide. They have large, colorful flowers with unique shapes, bloom for several months, and do not require soil or organic fertilizers (only need to spray chemical fertilizer solutions). They are clean and hygienic, with many varieties (divided into 7 major categories with over 500 varieties), suitable for indoor planting, and both flowers and leaves have high ornamental value. In recent years, various regions in our country have introduced orchid cultivation and propagation (G-Y) into the market, and the market prospects for orchids are very promising. There are many types of orchids with different fertilization methods. The following is an introduction to the fertilization techniques of orchids:
Cypripedium: Cypripedium requires less fertilizer, generally fertilizing only during the growing period. After new buds sprout in the growing season, a thin cake fertilizer water can be applied every 3 to 4 weeks, or a small amount of flower fairy granular fertilizer can be evenly applied around the pot, which can make the leaves lush and flowers beautiful. Fertilization should be stopped during the dormant period to allow for full dormancy.
Cymbidium: Cymbidium fertilization can be done in three ways: one is to mix the fertilizer in proportion with the planting material; the second is to pour the prepared fertilizer solution into the planting material in several applications; and the third is to make the prepared fertilizer into solid granules or blocks and apply them to the surface of the pot. More fertilization is needed during sunny seasons to ensure the plant's vigorous growth, while fertilization should be reduced or even stopped during dark, cold, or rainy days.
Phalaenopsis: Phalaenopsis requires less fertilizer and should generally follow the principle of "thin fertilizer, small amount, frequent application." The main points are as follows: Spring and summer are the peak growing seasons, and a thin liquid fertilizer with a high nitrogen content can be applied once a week. Autumn and winter are the flower stalk growth seasons, and a thin liquid fertilizer with a high phosphorus and potassium content should be applied every 10-14 days. A 0.5% solution of calcium superphosphate can also be used. Fertilization should be stopped after the buds appear, as it may cause early bud drop.
Dendrobium: Dendrobium likes fertilizer but should be fertilized thinly and frequently. In the seedling stage, a thin fertilizer solution with a higher nitrogen content should be applied, with a concentration of 20% and once a week. After the seedling stage, the plant grows faster, and a thin liquid fertilizer with a complete nutrient profile of nitrogen, phosphorus, and potassium can be applied every 2 weeks, with a concentration of 20%. Be careful not to splash fertilizer on the leaves during application.
Cattleya: Cattleya needs moderate and timely fertilization to make the seedlings grow strong and the flowers colorful. Methods are as follows: 1. Apply light fertilizer, with a concentration of 50%-80% of the flower fertilizer. Fertilization can start one week after the new buds emerge, and the principle of "small amount, frequent application" should be followed for young seedlings. 2. During the growing period, apply a very thin cake fertilizer water once every 10-15 days. When fertilizing, be careful not to apply it on the leaves and tender buds. A small number of thin cake fertilizers that have been fermented can also be placed evenly around the pot every month for absorption. 3. For plants that have reached flowering age, more phosphorus and potassium fertilizers should be applied during the bud differentiation period to nourish the roots and flowers, improve photosynthesis efficiency, and make the leaves tough.
The above () introduces you to the comprehensive introduction of various orchids with different fertilization methods, hoping to bring some knowledge of green plants to green plant enthusiasts.
