Why do rhododendron flower buds wither before they open
Rhododendrons have high ornamental value and many people like to keep them at home. However, some friends find that the rhododendron flower buds they care for fall off before they open. What is the reason? Let's find out below.
Reason for rhododendron flower buds withering before they open: low humidity
Rhododendrons need to grow in a humid environment, especially after the flower buds appear. It is necessary to maintain humidity, preferably keeping the air humidity around 70%. If the environment is too dry, the rhododendron flower buds will dry out before they open. Therefore, we should often spray water to keep them moist.
Improper lighting
Rhododendrons prefer to grow in an environment with scattered light and are sensitive to direct sunlight. Therefore, when caring for rhododendrons, do not place them in environments with direct sunlight, as this will not only burn the leaves but also damage the flower buds, causing them to wither before they open.
High temperature
Rhododendrons prefer a warm growing environment and are sensitive to temperature. They cannot tolerate cold or heat. When the temperature is too high, the rhododendron flower buds will become dry. Therefore, when the weather is hot, we need to strengthen ventilation and spray water appropriately to cool down.
When caring for rhododendrons, we should first maintain the humidity because they like a humid environment. If the care environment is too dry, we should often spray water to maintain humidity, which should not be lower than 50%. Do not place rhododendrons in environments with direct sunlight as they can get sunburned, but they also cannot be without light. It's best to put them in a scattered light environment. Finally, control the temperature, preferably keeping it around 20 degrees. Both too high or too low temperatures will affect the flower buds.
