The correct way to water roses
As the most popular ornamental flower in the courtyard, the most critical link in rose maintenance is watering. Scientific and reasonable irrigation methods can not only allow plants to grow healthily, but also promote the development of flower buds, but wrong operations can also easily lead to problems such as rotten roots and yellow leaves. This article will analyze in detail the correct way to open roses through four dimensions. Basic watering rules for roses Roses are typical plants that prefer moisture and avoid stagnant water. During the spring and autumn growth season, the soil moisture content needs to be maintained at 60%-70%. It is recommended to use the "knuckle test method": insert the index finger into the second joint in the soil, and pour it thoroughly if it is dry. Water is poured once in the morning and evening in summer, and extended to 7-10 days per time in winter. Special attention should be paid to the difference between potted plants and ground planting. It is recommended to use red pottery pots with drainage holes for potted plants, and 20-cm-high ridges need to be made for ground planting to prevent water accumulation. Different seasonal watering strategies Water every morning during the spring germination period. In summer, the "day-avoidance irrigation method" is used to replenish water after 18:00. In autumn, it is gradually reduced to 2-3 days per time. In winter, the principle of "slightly moistening" is maintained. In the rainy season, it is necessary to build a rainproof canopy to avoid root rot caused by continuous rain. Dispute over foliar watering of roses Regarding the issue of whether the leaves can be directly watered, it is necessary to distinguish the cultivation environment: When the locally planted roses are at high temperatures above 35 ° C, foliar spraying can be carried out to cool down at 6-8 in the morning, but this operation is strictly prohibited for potted plants. Experimental data shows that if water droplets remain on leaves in a closed environment for more than 4 hours, the mildew rate will increase by 80%. During the flowering period, it is also necessary to avoid splashing water droplets on the petals, otherwise ugly "water stains" will be formed. Treatment plan for special circumstances When insect pests such as red spider appear, a pressurized sprayer can be used to wash the back of the leaves, but the fan needs to be turned on simultaneously to accelerate drying. If liquid stains remain on the leaves after fertilization, they should be sucked off immediately with a soft cotton towel. Advanced Rose Watering Skills Water quality directly affects the acid-base balance of the soil. It is recommended to collect rainwater for irrigation, and tap water needs to be dried for 48 hours to remove chlorine. Citric acid solution (pH 5.5-6.5) is added once a month, combined with pine needle covering, to maintain an acidic environment for a long time. Users of smart irrigation systems can set the EC value between 1.2-1.6mS/cm to prevent salt accumulation. Nutrient water preparation plan Rice-washing water is fermented for 7 days and diluted to 10 times. Beer is watered once a month at a ratio of 1:50. Expired vitamin C tablets can enhance plant resistance after being dissolved. However, all nutrient solutions should be avoided during the high noon hours. Rose watering misunderstandings warning 90% of the deaths of potted roses are caused by "stagnant water in the tray." It is recommended to dump the residue after each watering. Be wary of the "illusion of surface dampness." Drought in deep soil can lead to the "upper dampness and lower drought" syndrome. Do not use ice water for irrigation in winter, and the difference between the water temperature and room temperature should not exceed 5 ° C.
Through scientific watering management, regular loosening of soil and root inspection, roses can be kept in their best condition. Remember the three-step rule of "observation-judgment-action" and flexibly adjust it according to the actual needs of the plants. You will surely be able to harvest a sea of roses blooming all over the garden.
