Four-season Begonia Care
Watering Moderately
Four-season begonia prefers a humid environment, but in the hot summer, slightly moist potting soil is recommended. Do not set a fixed schedule for watering, but always observe the dry and wet conditions of the potting soil. Water the plant when the potting soil turns white, and avoid excessive watering. The best time for watering is around 9 o'clock, preferably not watering until it is completely dry, but also not waiting until it is completely dry before watering.
Applying Fertilizer by Category
Summer fertilization of four-season begonia should be treated differently for new and old plants. For new plants propagated in the previous autumn, apply some well-rotted thin cake fertilizer water after each flowering, with a fertilizer-water ratio of 1:5, once a week, for two consecutive weeks, and the plant can bloom again after two weeks. For perennial old plants or weak plants, fertilization should be stopped when the temperature is above 25℃, and fertilization should be resumed after the dog days are over, to welcome the second flowering peak.
Reducing Temperature and Increasing Humidity
In the summer, high temperatures and dry air require not only shading and ventilation for four-season begonia but also multiple sprinklings of water around the plant's base throughout the day to lower the temperature and increase air humidity. Families with conditions can set up a sand bed in a corner of the balcony or courtyard, place the plant on the sand surface or in the sand bed, and wet the sand while watering the plant, which can help to cool down and increase humidity.
Preventing Diseases and Controlling Pests
Four-season begonia is prone to bacterial leaf spot disease under conditions of high temperature and humidity. Initially, dark brown spots appear on the leaf surface, which gradually spread into blackish-brown ring patterns. Before the disease occurs, an equal amount of Bordeaux mixture can be sprayed for prevention, and attention should be paid to improving cultivation conditions and management methods. Diseased leaves should be removed and destroyed at the initial stage of the disease to prevent further transmission. Summer is the peak season for aphids and red spiders, and it is necessary to control them in time with non-toxic pesticides.
The optimal temperature for the growth and flowering of four-season begonia is about 23℃, and in summer, it prefers a semi-shaded, cool, and well-ventilated environment, avoiding high temperatures, waterlogging, and direct sunlight. In summer care, we should follow its "temperament."
