How to care for四季海棠 in summer
This article introduces how to care for 四季海棠 in summer and teaches you the related knowledge of green plant maintenance, including key points for summer care. Here is a detailed introduction.
Four-season begonias often experience curling, yellowing, and falling leaves in summer, which is caused by the rise in temperature and strong sunlight. As 四季海棠 is not tolerant of high temperatures, when the ambient temperature exceeds 30°C, the plant stops growing and enters a dormant state. At this time, if exposed to direct sunlight, its leaves tend to curl and scorch, turning purple-red in color.
In fact, if 四季海棠 is well-maintained, providing a good growing environment in summer, the plant will grow and bloom normally. Let's find out how to care for 四季海棠 in summer.
I. Pay attention to shading
Four-season begonias enjoy light but also tolerate shade. During the vigorous growth period, it is beneficial to move the plant to a sunny location to receive more sunlight, which helps with growth and blooming. However, as summer approaches, with the increase in temperature and stronger sunlight, 四季海棠 that is still being maintained outdoors should be moved to a well-ventilated indoor area. 四季海棠 exposed to strong sunlight in summer can easily develop curled and scorched leaves, or even yellowing and falling leaves.
If maintained in a cooler environment in summer and with enhanced water and fertilizer management, many plants can continue to bloom.
II. Avoid overly damp potting soil
Many flower enthusiasts, worried about rapid water evaporation in summer, water their plants frequently, leading to consistently moist potting soil. Over time, this can damage the roots and cause stem rot and yellowing of the leaves.
How to care for 四季海棠 in summer
Although water evaporates quickly in summer, it is important to control the watering frequency appropriately. First, check the moisture level of the potting soil. If it is slightly moist, avoid watering again. Watering should follow the principle of "water when dry, and keep slightly moist." If concerned about rapid evaporation, you can spray water on the leaves to increase humidity.
Watering during the high temperatures of summer should be done before 8 a.m., avoiding the hot midday period to prevent damage to the plant and possible wilt.
III. Can you fertilize in summer?
Many enthusiasts ask whether they can fertilize 四季海棠 in summer. This depends on the situation. If the maintenance environment is warm and the plant is in a dormant state, it's best not to fertilize. However, if the environment is cool and the plant is continuously growing, it is possible to continue fertilizing to supplement nutrients and promote early blooming.
If you want 四季海棠 to bloom more, you can supplement it with 1-2 applications of phosphorus and potassium fertilizers before flowering. For example, you can use a 0.1% phosphorus acid monopotassium solution to spray on the plant leaves, which can increase the blooming amount.
IV. Increase environmental ventilation
In summer, 四季海棠 often experiences stem rot and yellowing or falling leaves, which is directly related to sunlight and watering, as well as the ventilation of the maintenance environment. In humid and stuffy conditions, houseplants are more likely to be infected with bacteria, leading to diseases and pests. It is important to enhance environmental ventilation and also consider spraying some fungicides in advance for prevention.
Caring for 四季海棠 in summer is crucial. If exposed to direct sunlight and rain, the leaves can become dry and curled, or even the stems can rot. If proper shading is provided and water and fertilizer care is enhanced, many plants can continue to bloom.
