Summer temperatures are high and most flowers are poorly grown. Flowers that are not resistant to high temperatures, such as short red, short, gerberas, and kaffir, grow very slowly when the temperature is high in summer, and the requirements for fertilizer are not high . At this time , fertilization should be stopped. If the cooling conditions are good , the flowers can be fertilized normally when the flowers can grow normally.
   Flowers that are in a semi-dormant state due to high summer temperatures, such as the rose, cyclamen, etc., should stop fertilizing, and start fertilizing after the temperature drops and resumes growth.
Â
For some high temperature resistant flowers such as zinnia, periwinkle, cockscomb, gladiolus, sunflower, etc., summer is the peak season for their growth and flowering. Fertilizer should be selected in the morning or evening, and the concentration of fertilization should be controlled to prevent burning. root. Immediately after fertilization, rinse the leaves of the flowers with water to prevent the leaves from splashing on the leaves.
   Aquatic flowers such as water lilies and bowls can be fertilized normally in summer. Most of them are buried with fertilized fertilizer in the root soil, and there is no burning roots.
