Rose = medicine jar? Learn these 5 skills
As the queen of flowers, although the rose is beautiful and moving, it is often called the "medicine jar." In fact, as long as we master scientific maintenance methods, we can get rid of the troubles of pests and diseases and realize the grand scene of blooming every month. This article focuses on the five common questions and teaches you how to create a healthy rose garden. The three key powdery mildew prevention and control systems for disease prevention and control require special vigilance against white powder on leaf surfaces in spring and autumn. It is recommended to adopt a "three-step prevention and control method": keep the distance between plants>30cm to enhance ventilation; spray atomized water in the morning to maintain 65% humidity; use 1500 times of powder rust gram for prevention every half of the month, and jointly treat infected plants with chlorothalonil. Black Spot Solution Make three preparations before the rainy season comes: pruning branches that are too dense at the bottom to ensure light transmittance; laying a 5-cm-thick pine scale covering to block the spread of bacteria; spraying Amioshou (10ml: 15L) immediately after rain to focus on processing leaf backs. Affected plants need to be removed and burned centrally to block the source of infection. Rhizobium eradication plan rose = medicine jar? Learn these 5 skills
When planting new seedlings, the roots were dipped with 3 times solution of K84 biological agent. In the early stage of the disease, a scalpel can be used to remove the tumor to healthy tissue, apply 0.1% potassium permanganate solution to the wound, and replace the sterile substrate (high-pressure treatment at 121℃ for 30 minutes). For severe infections, it is recommended to destroy the entire strain to avoid cross-infection. Dual strategies for pest management: annihilation of red spiders and implementation of the "three-three system" in the high-temperature and dry season: spray water on the back of the leaves every morning and evening to increase humidity; use abamectin and azifenil in rotation every three days; consolidate control after three consecutive applications. Use it with hanging yellow sticky insect boards to monitor insect population density. Three major lines of defense are arranged for ecological prevention and control of aphids in early spring during the germination period: planting repellent plants (mint/calendula); hanging silver-gray reflective films to interfere with aphids positioning; and artificially releasing ladybugs (5-8 per plant) for biological control. During the outbreak period, a solution of 22% fludinapyr suspension at 3000 times was used to mainly spray young shoots.
Through scientific environmental management (maintaining sun exposure for 6 hours + air circulation)+ precise control strategies, combined with monthly application of seaweed fertilizer to enhance resistance, a rose garden with zero pests and diseases can be created. Remember: Prevention is better than treatment. Regular inspections and early detection will allow your roses to truly achieve healthy and continue to bloom!
