How to water peony flowers in spring
As a classic flower with national beauty, watering management during spring maintenance of peony flowers directly affects the flowering quality. Mastering scientific water control can not only avoid the risk of root rot, but also promote flower bud differentiation. This article will systematically analyze the core points of spring watering of peony flowers from dimensions such as watering amount and water quality selection to time control. Spring watering amount control, drought tolerance characteristics and watering cycle, peony flowers have natural water storage capacity, and spring and autumn follow the principle of "seeing dry, seeing wet". During the spring germination period, water is watered every 10-15 days, and water is replenished when the soil layer is 3 cm dry. It is recommended to use the "weighing method" for potted peonies: record the weight of the pot after watering, and replenish water again when the weight is reduced by 30%. Soil moisture detection method Bamboo stick insertion method: Insert the dry bamboo stick into the soil for 5 minutes and then pull it out. If only the tip is wet, water is needed; infrared hygrometer detection: It is best to keep the soil moisture in the range of 40-50%. Key points for peony flower water quality treatment Water purification treatment uses tap water that is dried for 3 days to volatilize chlorine and the water temperature is consistent with the ambient temperature. The rainwater collection system has better effects, with the pH value controlled between 6.5 and 7.0, and the EC value <0.5ms/cm to avoid salt accumulation. Water quality improvement plans add citric acid to adjust alkaline water quality (0.5g per liter of water), or use a magnetized water treatment device. Be careful to avoid using cold boiled water that is boiled repeatedly because it contains too low oxygen. The best watering time window for peony flower watering period management is completed within 2 hours after sunrise (8-10 o'clock), when the temperature difference between ground temperature and water temperature is the smallest. Under special circumstances, water can be replenished 3 hours before sunset (15-17 o'clock), but it is necessary to ensure that the leaves are completely dry before nightfall. In special weather, watering should be postponed in late spring weather, and the dipping basin method should be used when the air humidity is greater than 80%. Build temporary rainproof canopies on continuous rainy days to avoid excessive soil moisture. Water control techniques during peony flower flowering period Water regulation during flower bud period Reduce watering amount by 30% after buds appear, and maintain moderate drought to promote flower bud differentiation. Use foliar spray instead of watering the roots, and maintain the air humidity at 60-65%. Rewatering management after flowers die, resume normal watering immediately after flowers die, and cooperate with the application of phosphorus and potassium fertilizers. The "small amount and multiple times" method is adopted in high temperature weather, and the amount of watering each time does not exceed 1/5 of the pot volume.
Scientific and systematic watering management can increase the flower diameter of peony by 15-20%, and extend the flowering period by 5-7 days. It is recommended to establish a watering log to record soil moisture, temperature and other parameters based on the specific growth status of the plant to form a personalized maintenance plan. Regularly observing the condition of the leaves (dew condensation on the leaves in the morning) can adjust the watering strategy in time, so that the peony flowers bloom with a more beautiful national color.
