How to raise five-color plum blossoms in spring
As the temperature rises, five-colored plum ushers in the most important growing season of the year. As a characteristic plant with both ornamental and medicinal value, its spring maintenance directly affects the growth and flowering effect of the whole year. Mastering these three core maintenance points can make your five-color plum burst into vitality in the spring and lay a solid foundation for subsequent growth. The best pruning time for five-color plum pruning is when the temperature stabilizes above 15℃. It is recommended to choose continuous sunny morning operations to avoid incision infection in the rainy season. Focus on pruning cross branches, sick branches and long branches, and keep the main branch length no more than 40 cm. The scientific pruning method uses a 45° oblique trimming method to ensure smooth incisions. The amount of pruning each time does not exceed 1/3 of the total branch quantity, and 3-5 bud points at the base are retained. Apply plant ash to the incision immediately after pruning to both disinfect and promote healing. Light control strategy for five-color plum light intensity requirements In spring, direct light needs to be guaranteed for 5-6 hours a day, and the light intensity is recommended to be controlled at 20,000 - 35,000 lux. The placement position can be adjusted so that the southeastern side of the plant can fully receive morning light. Coordinated temperature management When the night temperature is lower than 10℃, temporary insulation measures need to be taken. A transparent plastic film can be built around the plants to keep the daily temperature difference no more than 12 ° C to avoid falling leaves caused by sudden cold and hot. Water management points for five-colored plum The scientific irrigation cycle adopts the principle of "seeing dry, seeing wet", and water it after the surface soil is 2-3 centimeters dry. Flexible adjustment based on weather conditions, water should be poured once every 5 days on consecutive sunny days, and rainy weather should be extended to 7-10 days. The water quality optimization plan uses tap water that has been dried for 24 hours, or collects rainwater for better irrigation. It is recommended to use fish farming water once a month instead of regular watering. Its rich ammonia nitrogen content can promote the luster of leaves.
Through systematic pruning, light, and water management, and regular observation of plant conditions, the crown width of the five-colored plum can be increased by 30%-50% in spring. It is recommended to apply phosphorus and potassium fertilizers every 15 days to supplement nutrients, and at the same time pay attention to preventing high-incidence spring pests and diseases such as aphids, so that your five-colored plum can welcome the arrival of flowering in the best condition.
