What are the ways to fertilize roses? What are the precautions when fertilizing? Today, our Nanyang Rose Planting Base will explain these to everyone. Please refer to the detailed introduction below:
The rose planting base points out that there are two types of rose fertilization: root fertilization and foliar topdressing. When preparing the bed, make sure to apply enough base fertilizer, and little or no fertilizer is needed in the early stage. Roses require a nitrogen:phosphorus:potassium ratio of 1:1:2 or 1:1:3. Fertilization should follow the principle of applying thin fertilizers frequently. The concentration of foliar topdressing should not exceed 0.3%. The following situations should be noted when fertilizing: fertilize after flowering to ensure the nutrients needed for the next bloom; apply more phosphorus and potassium fertilizers and less nitrogen fertilizers after autumn; fertilize before and after pruning; when applying foliar topdressing, the spray should be even and thorough, avoiding rainy or cloudy days, and applying in the morning on a sunny, windless day.
Common chemical fertilizer formulas include: mixing 1kg of urea, 2kg of superphosphate, and 2kg of potassium sulfate and applying it promptly, with 40g per plant. Or mix 1.1kg of urea, 3.17kg of common superphosphate, 3.17kg of potassium sulfate, and 0.45kg of magnesium sulfate, apply immediately, do not store for long, and use 28g per plant.
Fertilization time and method: Fertilization is usually carried out a few days after irrigation when the soil is not too dry or too wet, spreading the fertilizer evenly around the plant, 20-25cm away from the stem. If the plant density is high, strip fertilization can be adopted, i.e., spreading the fertilizer between the rows of plants and then shallowly cultivating the soil, followed by watering to help dissolve and渗透 the fertilizer.
Supplementary chemical fertilizers are often applied after the previous crop flowers to promote new buds. Or when the soil temperature is low in early spring, microbial activity is poor, and organic fertilizers release slowly, to promote early spring flowering. Also, apply after pruning or when the plant is deficient in fertilizer.
Chemical fertilizers can also be dissolved in water to form liquid fertilizers, but be sure to pay attention to the application concentration, with the total amount of fertilizer to water ratio being one or two thousandths, as too high a concentration can damage the roots and cause adverse consequences.
Foliar fertilization: Foliar fertilization is a supplementary measure for fertilization and cannot completely replace soil fertilization. Since foliar fertilization uses less fertilizer and has quick results, with the fertilizer entering the sap flow within a few hours of application, it is especially suitable for targeted application when roses lack certain elements, and has been accepted by most producers.
Fertilizer mixing: It can be mixed according to the needs of roses or used alone. Common combinations include: 1.25g of urea, 1.25g of potassium dihydrogen phosphate, and water, forming a complete nitrogen-phosphorus-potassium fertilizer with a concentration of one thousandth of 2.5. Another formula is: 112.7g of urea, 112.7g of potassium sulfate, 56.3g of magnesium sulfate, 28.2g of ferrous sulfate, and 284.3L of water, with a concentration of one thousandth of 1.25. Formulas to correct micronutrient deficiencies: 15g of manganese sulfate, 20g of magnesium sulfate, 10g of chelated iron, 5g of boric acid, and 25L of water, with a concentration of two thousandths.
