Orchids, known as "gentlemen among flowers", have won the favor of numerous flower enthusiasts with their elegant posture and fresh fragrance. To grow orchids well, fertilization is one of the key steps. Correct fertilization methods can not only promote orchid growth but also make the flowers more vibrant and attractive. This article will introduce in detail the methods of orchid fertilization to help you cultivate beautiful and healthy orchids.
Basic principles of orchid fertilization1. Moderate fertilization: Excessive fertilization can cause the orchid roots to rot, while insufficient fertilization will affect growth. Fertilization should be moderate, following the principle of "frequent application of thin fertilizer".
2. Choose the right fertilizer: Orchids have high requirements for fertilizer and special fertilizers for orchids, such as orchid-specific compound fertilizers and organic fertilizers, should be chosen.
3. Pay attention to the fertilization time: Orchids have a higher demand for fertilizer during the periods of vigorous growth and flowering, and fertilization should be strengthened during these two stages.
Specific methods of orchid fertilization1. Application of base fertilizer
(1) When planting orchids, an appropriate amount of organic fertilizer such as decomposed chicken manure or cow manure can be added to the bottom of the pot as base fertilizer.
(2) The amount of base fertilizer should not be too much to avoid affecting orchid growth.
2. Application of top dressing
(1) Vigorous growth period: Apply orchid-specific compound fertilizer once every 10-15 days, with a dosage of 10-15 grams per pot.
(2) Flowering period: 15 days before flowering, the dosage can be increased to 20-30 grams per pot.
(3) When fertilizing, sprinkle the fertilizer on the surface of the pot and then water it to dissolve the fertilizer.
3. Foliar application
(1) During the periods of vigorous growth and flowering, foliar application can be carried out using a 0.2% phosphorus potassium acid solution.
(2) When applying, make sure to spray evenly and avoid letting the fertilizer drip on the leaves, causing burns.
Points for attention in fertilization1. After fertilization, observe the growth of the orchid. If there are signs of poor growth or yellowing leaves, stop fertilizing immediately.
2. Keep the soil moist after fertilization to avoid fertilizer clumping.
3. Avoid fertilizing during high temperatures to prevent the orchid from getting heat stress.
