What is the cultivation method for roses in summer?
The most important aspects of cultivating roses in summer are appropriate shading and reducing temperature. The high summer temperatures can cause excessive evaporation and water loss, so it is necessary to supplement water in time, usually twice a day, maintaining humidity at around 80%. As summer enters a dormant period, fertilization should also be reduced, and light pruning should be performed.
1. -- Appropriate Shading --
Roses are plants that love sunlight and require ample light for growth and flowering. However, the intense sunlight in summer, especially for extended periods under high temperatures, can lead to leaf and petal burn due to water loss. In summer, roses should be placed in diffused light and not continuously kept outdoors, especially during the afternoon, when appropriate shading is necessary.
2. -- Sufficient Watering --
With higher temperatures in summer and intense transpiration, water loss is greater than at other times. Therefore, watering should be frequent. Typically, water in the morning and evening, and avoid watering at noon, as this can cause a sudden drop in soil temperature, harming the plant. If the plant shows signs of wilting,喷 water on the branches and leaves to maintain humidity at around 80%.
3. -- Reasonable Fertilization --
When the temperature exceeds 35 degrees Celsius, roses enter a semi-dormant state and do not absorb fertilizer well, so fertilization should be reduced. In summer, use dilute, light fertilizer solutions, combining fertilization with watering to reduce fertilizer concentration. When the leaves are growing well, you can spray a diluted potassium dihydrogen phosphate solution on the leaf surface to maintain a green leaf color.
4. -- Pruning Method --
Roses grow slowly in summer and should be pruned lightly, removing excess spent flowers and buds promptly to avoid nutrient consumption and to accumulate nutrients for the next flowering. If there are long, unnecessary branches or overlapping branches, they should be thinned, cutting off about one-third to create a reasonable spatial structure and pruning about one centimeter above the leaves.
