Fertilizing methods for rose flowers
If roses want to bloom into beautiful flowers, scientific fertilization is the key. As the "queen of flowers", roses have strong but sensitive needs for nutrients, and require precise regulation of fertilization plans at different growth stages. Mastering the correct fertilization method can not only promote the healthy growth of plants, but also prolong the flowering period and colorful colors. Comprehensive strategy for fertilizing roses in four seasons: spring growth and fertilization plan from March to May is the critical period for the germination of new roses. It is recommended to apply organic liquid fertilizer diluted 200 times every week. It is recommended to use decomposed sheep manure and fish protein fertilizer alternately. It can not only supplement nitrogen to promote the growth of branches and leaves, but also supplement trace elements to enhance disease resistance. Before fertilization, loosen the soil to keep the soil breathable to avoid hardening and affecting nutrient absorption. Nutritional management techniques for flowering period use a fertilizer combination based on phosphorus and potassium fertilizers during the bud period, which can be prepared with bone meal + seaweed fertilizer in a ratio of 1:3. When fertilizing, pay attention to avoid the high temperature period at noon and bury it shallowly along the edge of the pot to avoid contact with the root system. Combined with foliar spraying of potassium dihydrogen phosphate (concentration of 0.2%), the flower buds can be increased by more than 20%. Precautions for fertilization operations The principle of matching base fertilizer and top dressing should account for 60% of the total fertilizer during winter dormancy. Rapeseed cake + chicken manure + plant ash is recommended (ratio 2:1:1). When new buds sprout in early spring, add quick-acting fertilizer after the base fertilizer is decomposed. The peak period for topdressing will enter from May. The principle of "applying thin fertilizer frequently" is adopted, and the next day after each fertilization is watered thoroughly to dilute the residue. The special treatment plan will immediately stop fertilizer when the leaves are found to be yellow and wash the basin soil with clean water three times. In the rainy season, it is necessary to reduce the frequency of fertilization and switch to slow-release fertilizer granules. Newly transplanted plants should wait until new roots grow before applying fertilizer to avoid burning roots. It is recommended to use liquid fertilizer for potted roses, which makes it easier to control the concentration.
A scientific fertilization system needs to be flexibly adjusted in conjunction with observation of plant conditions. It is recommended to establish a fertilization log to record the time, type and plant response of each fertilization. Through observation over 3-5 growth cycles, we can gradually grasp the most suitable fertilization plan for our own roses, so that every flower season can harvest surprises.
