How to judge how much chrysanthemum to water
As a famous traditional flower in China, the most critical one of its maintenance points is water management. Many flower lovers often cause their plants to wither or rot due to improper watering during the maintenance process. Only by mastering scientific judgment methods can the chrysanthemums bloom more brightly. The four golden rules for watering chrysanthemums are related to the amount of water. The soil needs to be kept moist during the spring and summer growing periods. It is recommended to water every morning and combine it with foliar spray. The autumn bud pregnancy period is adjusted to the "see dry and see wet" mode, and the surface soil is watered thoroughly after it turns white. During the winter hibernation period, water needs to be strictly controlled, and a small amount of water can be replenished along the edge of the basin every 15-20 days. Differences in plant growth stages During the seedling period, the dipping pot method is used to ensure that the roots absorb water uniformly, and each soaking shall not exceed 3 minutes. During the strong seedling period, use the "three-three system" watering method: 3 times a week, 3 days apart each time, and 3 rounds each time. Water control and flower promotion techniques were implemented 10 days before flowering, and the flowering period could be prolonged by reducing watering amount by 30%. The soil condition diagnosis method adopts the method of "one look, two knocks and three tests": observe the color change of the surface layer 2 cm soil, knock the pot body to listen to the sound to distinguish the humidity (dull sound indicates humidity), and use the bamboo stick insertion method to detect the deep water content. It is suggested that the permeable matrix of 40% pearlite +60% moldy soil can effectively prevent ponding. Meteorological factors control high temperature season (>28℃) to implement the morning and dusk double watering strategy, combined with the use of sunshade net. The "funnel type" drainage method is used in the rainy season: a 3cm ceramsite layer is placed on the bottom of the basin, and a diversion groove is opened around the basin. When the air humidity is greater than 70%, the tray water supply method is used to maintain moderate humidity through evaporation.
After mastering these four dimensions, you can combine the "Chrysanthemum Intelligent Watering Formula": single watering volume (ml)= pot diameter (cm) × plant height (cm) ×0.8. Regularly observe the leaf status. Healthy chrysanthemum leaves should stretch naturally at 45°. If droop or curl occurs, the plan needs to be adjusted in time.
