Outdoor Management of Rose bushes in Summer
In summer, it is important to shade rose bushes during the hot afternoons to prevent scorching of leaves and petals, and to replenish the moisture lost through transpiration promptly. It's advisable to water them in the morning and evening, and to spray water on the branches and leaves at other times to maintain humidity at around 80%. Reduce the concentration of fertilization appropriately in summer and prune the spent flowers and branches in a timely manner.
1. -- Appropriate Shading --
Although roses are sun-loving plants, they need to be shaded appropriately during the high temperatures of summer, especially during the hot direct sunlight afternoons. Otherwise, it can lead to water loss through transpiration in the leaves, wilting of flowers, and the plant entering a dormant state without flowering. You can move them indoors or under a shady eave or large tree after the sun comes out, and move them to the sun in the morning and evening.
2. -- Sufficient Watering --
With high temperatures in summer, the plant's transpiration rate is fast, and water evaporation accelerates, so it is necessary to replenish the lost water. Watering can be done in the morning and evening, but not at noon, as it can cause a sudden drop in soil temperature and harm the plant. At other times, you can spray water on the branches and leaves to maintain the environmental humidity at around 80%.
3. -- Reasonable Fertilizing --
As temperatures rise in summer, plants may enter a dormant state, so the amount of fertilizer should be reduced compared to the growing period. You can choose dilute nitrogenous fertilizer water, mixed with watering to lower the concentration. Fertilization should stop when temperatures exceed 35 degrees Celsius. When the leaves are growing well, you can spray a solution of potassium dihydrogen phosphate on the leaf surface to keep the leaves green.
4. -- Proper Pruning --
Pruning of rose bushes in summer should be light, mainly to remove excess spent flowers and flower buds to avoid nutrient waste, allowing nutrients to concentrate on the flowers currently in bloom, and to accumulate nutrients for the next flowering. If there are overly long branches, they should be cut by about a third to make the plant look more attractive and prevent them from blocking each other.
