When do pomegranate flowers bloom?
As a classic plant cultivated in the courtyard, pomegranate flowers are deeply loved for their fiery red flowers. Its flowering rules and maintenance methods directly affect the viewing effect. Mastering the correct time points and cultivation skills can make this midsummer red glow bloom more brilliantly. Characteristics of pomegranate flower growth cycle Natural flowering rules In temperate climate zones, pomegranate flowers usually bud in early April, enter full flowering in early May, and continue to open until mid-July. Due to the slow rise in temperatures in the northern region, flowering may be delayed by 2-3 weeks. When the temperature difference between day and night is maintained at 8-12℃, it is most conducive to flower bud differentiation. The flower shape evolves into a green-green bud at the beginning of its evolution, and completely unfolds into a bell-shaped flower with a diameter of 3-5 cm after 3-5 days. Single-petal varieties have 5 corrugated petals, and double-petal varieties can have more than 20 petals. The orange-red color gradually deepens with the increase of sunshine, and the pistil stigma presents a unique gold-silk-like structure. Prolonged flowering maintenance techniques Light control methods need to ensure 6 hours of direct light per day, and east-west planting layout can be adopted. Use a sunshade net to filter 30% of the light during strong light periods (11-15 o'clock) to prevent scorched petals. Regularly rotate the potted plant to ensure uniform light reception and avoid off-crown growth. The water management strategy adopts the irrigation principle of "see dry, see wet", and water is poured thoroughly when the topsoil is 2 centimeters dry. During flowering, it is recommended to implement root drip irrigation in the early morning and maintain the air humidity at 40-60%. Drainage ditches need to be set up during the rainy season to prevent stagnant water causing flower drops. The nutrient supply plan applies phosphorus and potassium fertilizers (N-P-K=5-10-10) during the bud stage, and topdressing once every 15 days. Combined with foliar spraying 0.2% boric acid solution, it can enhance the coloring degree of flowers. After flowers fade, timely replenish decomposed cake fertilizer to promote fruit development. Special climate response measures When the spring cold wave hits, temporary insulation sheds are built to maintain temperatures above 15℃. Artificial light is replenished for 4 hours/day in continuous rainy and rainy weather, and full-spectrum plant lights are used to illuminate 50 centimeters away from the canopy. During the dry hot air season, spray in the morning and evening to moisturize the leaves to keep them straight and straight.
By accurately grasping the phenological characteristics of pomegranate flowers and combining scientific maintenance methods, the viewing period can not only be extended to more than 90 days, but also the fruit setting rate can be improved. It is recommended to regularly observe the status of the plants and adjust management measures in a timely manner so that this auspicious flower, which symbolizes prosperity, blooms year after year.
