Jasmine fertilization methods
As a famous traditional flower in China, the fragrance of jasmine is deeply loved by people. If jasmine flowers continue to bloom year after year, scientific fertilization is the key link. Reasonable fertilization can not only promote the luxuriant branches and leaves, but also make the flowers have strong aroma and prolong the flowering period. Master fertilization techniques and make your jasmine flowers the most dazzling star in the courtyard. Selection of fertilization timing, growth cycle, fertilization node Jasmine flowers need to go through three important fertilization stages every year: nitrogen and phosphorus compound fertilizers are used to promote the growth of new buds during the spring germination period (March to April); additional phosphorus and potassium fertilizers are applied to improve the quality of flower buds; In full flowering period (July to September), diluted liquid fertilizer is added every 10 days to maintain flowering energy. Apply slow-release fertilizers such as bone meal before winter (late October) to enhance the cold resistance of the plants. Special climate adjustment strategies should delay fertilization in continuous rainy weather to avoid nutrient loss. When the temperature exceeds 35℃, leaf spraying is switched to, and 0.2% potassium dihydrogen phosphate solution is used for mist spraying, which not only supplements nutrients but also reduces leaf temperature. Scientific ratio of fertilizers, base fertilizer selection and application When changing pots, it is recommended to use the formula of decomposed sheep manure (3 parts)+ pine needle soil (5 parts)+ perlite (2 parts), and mix 20g of cake fertilizer per kilogram of substrate. This ratio not only ensures basic nutrients, but also improves soil permeability. Recommended topdressing formula It is recommended to use self-made nutrient solution during the growth period: fish protein (5ml)+ seaweed extract (3ml)+ iron chelate (1g) mixed with 1L water, watered twice a month. Using banana peel fermentation liquor (diluted 1:20) and eggshell powder (5g/pot) during flowering period can extend the flowering period of a single flower by 2-3 days. Correct fertilization techniques The root system maintenance and fertilization method adopts "circular ditch application": dig a circular ditch of 5 cm deep 10cm away from the main stem, apply decomposed soybean cake fertilizer (50g/plant), and then cover it with soil. Combined with root irrigation with EM bacterial solution once a month, the beneficial flora can be increased and the fertilizer utilization rate can be increased by 30%. The key points of foliar fertilizer supplementation should be carried out on sunny days and evenings, with emphasis on spraying the back of the leaves. Using a mixed solution of brassin (0.01ppm)+ urea (0.2%) can not only replenish nitrogen, but also enhance plant stress resistance. Pay attention to stop foliar fertilization during the bud emergence period to avoid flower buds falling off. Precautions and Misunderstandings: Fertilization taboos remind newly planted plants not to apply concentrated fertilizer within 20 days, and start applying thin fertilizer frequently after new roots germinate. Avoid applying undecomposed raw fertilizers, which may cause root rot. Avoid continuous use of ferrous sulfate in acidic soil areas and apply it up to three times a year. When fertilizer damage occurs in handling abnormal situations, immediately wash the basin soil with clean water three times, cut off the charred roots and replace it with new soil. When leaves chlorosis are supplemented with iron chelate (1g/L) once a week, it can recover for 3 consecutive weeks. Fertilizer should be stopped and water should be controlled when buds fall during flowering, and fertilization should be resumed after new buds sprout.
Through scientific and systematic fertilization management, jasmine flowers can bloom 4-5 times a year. Keep in mind the principle of "applying thin fertilizer frequently, applying balanced nutrition" and flexibly adjusting based on the actual condition of the plant, you will be able to cultivate high-quality jasmine with flourishing flowers and luxuriant leaves. Regularly observe plant responses, establish a fertilization log, and gradually form the most suitable fertilization plan for your own jasmine.
