Method of Cultivating Large Flowering Roses
With both ornamental and medicinal values, large flowering roses are a distinctive member of the rose family, known for their plump flower buds and robust vitality, making them a popular choice for courtyard greening. However, to make this unique plant bloom magnificent flowers, it is necessary to master scientific cultivation techniques. This article will systematically analyze the six core points of home cultivation, from environmental control to pest and disease prevention.
Create an Ideal Growing Environment
Temperature and Light Management
Large flowering roses thrive best in a warm and humid environment with temperatures between 15-28°C. Full sunlight can be provided during spring and autumn to promote bud differentiation. In summer, a shade net should be set up to filter 40% of the sunlight, and in winter, when temperatures drop below 5°C, it is recommended to move the plant to an indoor greenhouse with at least 4 hours of scattered light daily.
Humidity and Ventilation Adjustment
Use a soil moisture meter to monitor the water content, maintaining 60% humidity during the growing season, and spray the leaves in the morning and evening to maintain air humidity. Ensure a pot spacing of more than 50cm and use a ceiling fan to promote air circulation, preventing the growth of mold.
Scientific Water and Fertilizer Management
Accurate Irrigation Plan
Adopt the "moist when dry" watering principle, watering thoroughly every 3 days during spring and autumn, twice a day in summer (avoiding the midday high temperatures), and controlling water to once a week in winter. It is recommended to use rainwater or tap water that has been standing for 2 days, with the water temperature matching the ambient temperature.
Nutrition Supply Strategy
Apply a balanced liquid fertilizer (diluted 1000 times) every 15 days during the growing season, and add phosphorus and potassium fertilizers during the bud formation stage. It is recommended to use decomposed sheep manure as a base fertilizer, applying 200g along the pot edge every early spring, combined with EM bacterial agents to enhance fertilizer efficiency.
Comprehensive Pest and Disease Control
Disease Prevention System
During the high-incidence period of (T-J) disease (plum rain season), spray mancozeb 800 times liquid in advance, once every 10 days. Remove diseased leaves immediately and spray with benz醚甲环唑, and simultaneously supplement potassium dihydrogen phosphate to enhance disease resistance.
