Flower summer and autumn fertilization essentials
(1) Summer fertilization prevents "burning". Summer temperatures are high and most flowers have a poor growth potential. Flowers that do not tolerate high temperatures, such as a bunch of red, petunia, gerbera, and clivia, grow extremely slowly during high summer temperatures and require less fertilizer. At this time, fertilization should be stopped. If the cooling bar waits: Well, the flowers can fertilize normally when they grow. In semi-dormancy summer flowers, such as roses and cyclamen, fertilization should be stopped, and fertilization should be started after the temperature drops, and growth resumes. For some heat-resistant flowers such as zinnia, periwinkle, cockscomb, gladiolus, sunflower, etc. Summer is the peak season for their growth and flowering. Fertilizer should be used normally. However, due to the high temperature during the daytime in summer, fertilization should be selected in the early morning or early evening. The concentration of fertilization should also be controlled to prevent root burning. Immediately after fertilization, the leaves of the flowers should be washed with clean water to prevent splashing on the leaves of the leaves. The water-fed flowers such as water lilies and lotus flowers can also be fertilized normally in the summer. The root soil can be buried with decomposed fertilizer without burning. Root burning phenomenon. (B) The use of nitrogen fertilizer in the autumn should be cautious. However, for winter dormant flowers, the application of a large amount of nitrogen fertilizer in autumn will induce the occurrence of autumn shoots. The occurrence of autumn shoots not only consumes nutrients stored in flowers, but also affects the growth and blooming of flowers in the second year of spring. Moreover, because the dormancy time of the flowers will be postponed after the autumn shoots occur, and the cold damage will occur when encountering low temperatures, it is necessary to apply phosphorus and potash fertilizers to the dormant flowers in winter. Phosphorus and potassium fertilizers can promote the accumulation of nutrients in flowers. To lay the foundation for the second year of growth and flowering. It is not possible to use nitrogen fertilizer in the autumn, and it is still possible to apply nitrogen fertilizer to flowers that do not sleep during the winter. In particular, the foliage-based plants should still use nitrogen-based fertilizers. However, in the application of nitrogen fertilizer should pay attention to the combination of phosphorus and potassium fertilizers. Reasonable application of P and K fertilizer can improve the cold resistance of flowers. Winter flowering plants such as cineraria, pueraria, cyclamen, poinsettia and waxberry are vegetative stages in the early autumn. Fertilizers dominated by nitrogenous fertilizers should be applied. Late autumn is mostly during the budding stage. When fertilizing such flowers, it should be Phosphorus and Potassium fertilizers are dominant, and nitrogen fertilizer is the vice. Nitrogen fertilizer is not conducive to flowering in winter. 4G Xylitol Sachet,Plant Sourced Xylitol,Natural Xylitol Sweetener,Xylitol Crystal Powder Soar Biotech Co.,Ltd , https://www.xylitgum.com
