How to Care for Multiflora Roses
As a popular variety in the floral art world, multiflora roses are beloved for their dense buds and ultra-long blooming period. However, to make these delicate buds bloom perfectly, professional techniques are required from pruning to maintenance. This article will systematically explain the complete care process of hydroponic multiflora roses through four dimensions.
Ⅰ. Key Steps in Plant Preprocessing
Techniques for Pruning Multiflora Roses
After unpacking the bouquet, immediately handle with a special flower剪 that has been disinfected with alcohol: ① Remove all side branches and unopened small buds to prevent nutrient diversion; ② Retain robust leaves 5-10 cm below the flower head, and cut off all other leaves; ③ Peel off the outer damaged petals layer by layer until the complete flower shape appears. Note that a cotton pad should be used to wipe the scissors after each cut to prevent cross-contamination.
Standard for Cut Surface Treatment
Use a 45-degree diagonal cut 3 cm from the base, with the cut area reaching 2/3 of the diameter of the stem. If the stem is thick, a cruciform cut can be used, with a needle puncturing three small holes 1 cm above the cut to enhance water absorption efficiency.
Ⅱ. Hydroponic Environment Setup Plan
Requirements for Container and Water Quality
Choose a transparent glass bottle 25-30 cm high and fill it with 20-25℃ pure water to 2/3. Add a professional preservative (a triple composite formula containing disinfectant, sugar, and ethylene inhibitor) to each liter of water, which can extend the blooming period by 5-7 days.
Light and Temperature Control
Place in a well-lit area with scattered light, avoiding direct sunlight. Maintain a constant temperature of 18-22℃, with a day-night temperature difference not exceeding 5℃. Use a thermometer and hygrometer to monitor, and keep the relative humidity between 65%-75%.
Ⅲ. Key Points of Daily Maintenance
Water Change and Cleaning Specifications
Change the water daily if no preservative is added, or extend to every 3 days with preservative. Thoroughly clean the inside of the vase each time you change the water, using a soft brush to remove slime biofilm. Re-cut the roots 1-2 cm to keep the cut fresh, and消毒 tools before and after cutting.
Preventive Measures for Diseases
When seeing絮状物 in the water or transparent mucilage on the stem, immediately soak the base in 0.1% sodium hypochlorite solution for 10 minutes. Use a cotton swab dipped in diluted white vinegar to wipe the stem above the water surface once a week, which can effectively prevent gray mold disease.
Ⅳ. Strategies for Dealing with Special Issues
If the flower head droops, try the deep water emergency method: Soak the whole branch, including the flower head, in 30℃ water for 2 hours, then prune it after recovery. When the petal edges become crispy, maintain local humidity with a humidifier and add 0.5g/L of calcium and magnesium nutrient solution to the water to enhance cell wall strength.
Through scientific pruning techniques, precise environmental control, and standardized maintenance processes, multiflora roses can maintain a 15-20 day viewing period. It is recommended to establish a maintenance log, recording temperature, water change cycles, and preservative dosage, to gradually optimize the maintenance plan and ensure that each rose can bloom in the most beautiful way.
