What fertilizer can orchids use to bloom more
As a representative of elegant flowers, orchids have a direct impact on their ornamental value. Reasonable fertilization is the key to promoting flowering, but commercially available fertilizers are expensive and difficult to control their compositions. This article will systematically analyze the nutritional elements needed for orchids to bloom, and teach you the detailed formulas of three homemade flower fertilizers, so that you can grow pop-pot orchids at the lowest cost. 1. Analysis of key nutrients for orchid flowering 1.1 The core role of phosphorus and potassium potassium dihydrogen phosphate can promote flower bud differentiation, and bean cake fertilizer contains natural auxin. It is recommended to apply 0.1% potassium dihydrogen phosphate solution every month and alternately use it with decomposed soybean cake fertilizer (diluted 10 times). Experimental data shows that this combination can increase the number of flower arrows by 40%. 1.2 Fertilizer use is forbidden to stop when it exceeds 32℃ in summer and 10℃ in winter. Fertilizing during dormant period can easily cause fertilizer damage. Newly placed orchids need to be delayed for 2 months before fertilizing to avoid burning roots. Note that the ratio of nitrogen, phosphorus and potassium is controlled at 1:3:2. Excessive nitrogen supplementation will lead to excessive leaf growth. 2. Three kinds of homemade orchid fertilizer formulas 2.1 Nitrogen fertilizer: Take 500g of fresh vegetable leaves +100g of expired milk powder from vegetable leaf fermentation liquor, crush it, and place it in a transparent container, and add rice washing water until it is 80% full. Open the lid regularly to vent air, and take the supernatant and dilute it at 1:50 after 45 days. This formula is rich in amino acids and is especially suitable for promoting new shoots in spring. 2.2 Phosphate fertilizer: Collect 500g of fish bones, eggshells, etc. from bone meal nutrient solution, boil and disinfect, dry and crush. Add 10ml of EM bacterial agent and 50g of brown sugar, and ferment in a sealed manner for 60 days. When using, take 10ml of the original solution and mix it with 1L of clear water, and water it twice a month before flowering. 2.3 Potassium fertilizer: Pine ash is the best choice for the plant ash extract, and soak it for 24 hours at a ratio of 1:10. After filtration, a weak alkaline solution with a pH of about 8.5 is obtained, which not only supplements potassium, but also prevents root rot. Be careful to use it 7 days apart from acidic fertilizers. 3. The scientific fertilization operation guide recommends adopting the "three-period fertilization method": use nitrogen fertilizer to promote buds in spring (diluted by 2000 times), transfer phosphorus and potassium fertilizer in late summer (diluted by 1500 times), and complete elemental fertilizer after flowering (diluted by 2500 times). Combined with foliar spraying (0.05% potassium dihydrogen phosphate) once a month, the flowering volume of a single plant can be increased by 60%.
Mastering these homemade fertilizer techniques can not only save maintenance costs, but also accurately regulate nutrition according to the growth stage of orchids. Remember the golden rule of "applying thinly and diligently" and with appropriate light and ventilation, your orchids will surely bloom amazing flowers every year.
