How does Rhododendron spend the summer
The following is an introduction to the topic of Rhododendron summer care and related topics such as the cultivation tips for maintaining Rhododendron during the summer. Let’s get to know more about it together.
Also known as Azalea, the Rhododendron is an evergreen or semi-evergreen shrub. There are single-petal and double-petal varieties of Rhododendron, which are generally divided into three types: spring Rhododendron, summer Rhododendron, and western Rhododendron. Some Rhododendrons grow leaves before blooming, some bloom before growing leaves, and others germinate flowers and leaves simultaneously. The flowers are large, colorful, and beautiful. The maintenance methods for all types of potted Rhododendrons are basically the same.
Five tips for caring for "Rhododendron" in the summer to prevent leaf drop and promote lush growth and abundant blooming
If the potted Rhododendron at home is not doing well, blooms few flowers, or even turns yellow and drops leaves, pay attention to the following reasons and measures:
First, water appropriately
If it is during the spring bud differentiation and flowering period, when water consumption is high, it is necessary to water frequently and promptly to prevent the potting soil from drying out, which can lead to the dropping of flower buds and a shortened flowering period. Keep the potting soil slightly moist, and pay even more attention to watering in the summer when temperatures are high. Water once a day, and the potting soil should not be dry. If the potting soil is too dry, it can cause leaf drop or dried branches.
Second, maintain a semi-shaded, cool environment
Although Rhododendron is a long-day plant, it is susceptible to sunburn and intense sunlight, so it is not suitable for long hours of strong sunlight in the summer. During high summer temperatures, drought, and strong sunlight, it is essential to protect against sun exposure and provide shade to prevent leaf damage, chlorophyll damage, which can cause the leaves to turn brown or even drop.

Third, care during the dormant period
When the temperature exceeds 32 degrees Celsius in the summer, Rhododendron will enter a semi-dormant state and may even stop growing. During this time, it is necessary to maintain a certain level of air humidity by frequently spraying water. It is most afraid of dry air, but the potting soil should not have积水 or be short of water to avoid affecting root growth, as its roots are very delicate.
Fourth, ensure ventilation and air circulation
In the summer, Rhododendron should be placed in a location with good ventilation and light and should not be placed in a completely dark or confined space. It should be placed in a bright and airy area.
Fifth, soil and fertilization
The soil for growing Rhododendron is also very important. Do not use soil that is too compacted and poor in nutrients. It is best to use mostly decomposed leaf soil with a small part of garden soil and sand, and add a small amount of organic fertilizer, such as bone meal or cake fertilizer residue. This mixed soil is acidic and very beneficial for the growth of Rhododendron, promoting continuous germination of new buds, abundant flowering during the blooming period, and full of flowers on each branch.
