In North China and other areas, the summer weather is hot and the rainfall increases, which is the peak period for the growth and development of most flowers, and also a good time for cutting propagation of flowering trees. However, it is also a period of mass occurrence of diseases and pests, so it is necessary to strengthen management and pay attention to the following tasks:
(1) Lighting and shading
During the severe heat of summer, the scorching sun is not conducive to the growth and development of many potted plants. Therefore, it is necessary to treat them differently according to the living habits of various flowers. Flowers that enjoy sunlight, such as poinsettia, croton, pomegranate, hibiscus, fig, rose,米兰, and white orchid, should be placed in a sunny location for maintenance. During the heat of summer, it is necessary to provide some shading for flowers like米兰, white orchid, hibiscus, and chrysanthemum. Flowers like camellia, azalea, gardenia, kaffir lily, and nandina should be placed in a well-ventilated and shaded area after entering summer. Orchids, daylilies, and nandina should be placed under weak or scattered light. At the same time, measures such as shading, sprinkling water, and covering the pots should be taken to lower the temperature and prevent heatstroke.
(2) Watering and fertilizing
The temperature in summer is high, and water evaporates quickly, so potted plants should be watered in time. However, different flower varieties have different requirements for water. Flowers that enjoy moisture, such as narcissus, monstera, and calla lilies, require sufficient water. Flowers that enjoy humidity, such as米兰, jasmine, oleander, and hibiscus, should be watered once in the morning and once in the late afternoon or evening. The amount of watering depends on the size of the plant, weather changes, and the actual dryness or wetness of the potting soil. Flowers grow quickly in summer and should be supplied with adequate fertilizer in time. Fertilizing also needs to be treated differently; for general potted plants, a thin liquid fertilizer can be applied every 7 to 10 days; for flowers that prefer acidic soil, iron sulfate fertilizer can be applied every 10 days or so. When fertilizing, avoid splashing fertilizer on the leaves, as it can damage the leaf surface. Fertilizing in summer should be done in the evening. Before fertilizing, pay attention to loosening the soil, which is beneficial for root absorption of fertilizer and water, as well as for the reproduction and growth of microorganisms, promoting the acceleration of the decomposition of organic matter in the soil, and providing a variety of nutrients for the growth and development of potted plants. After fertilizing, be sure to water the next day.
(3) Pruning and ventilation
Pruning of potted plants in summer mainly involves pinching, removing buds, removing leaves, thinning flowers, and thinning fruits. For some annual herbs, pinching is necessary when they reach a certain height to promote branching and flowering. For some woody flowers, such as kumquat, it is also necessary to pinch when the branches grow to 15-20 centimeters long to concentrate nutrients and benefit flowering and fruiting. In summer, adventitious buds often occur at the base of the stems or trunks of some flowers, which consume nutrients and disrupt the plant shape, so they should be removed in time. For some ornamental flowers, such as chrysanthemum, camellia, and rose, some excess flower buds should be removed to make the flowers larger and more colorful. For some ornamental fruit flowers, such as pomegranate, kumquat, and fingered citron, some young fruits should also be removed in time, usually leaving only one fruit on short fruiting branches for better size and color. Additionally, when finding luxuriant branches, they should be pruned promptly. During pruning, the shaping can be done according to the morphological characteristics of the flowers and personal preferences.
(4) Cutting and sowing
Summer is a suitable time for cutting some evergreen flowering trees, such as cutting米兰, jasmine, azalea, and hibiscus, which are easy to survive. The dog days are also a good time for budding and grafting, such as budding plum and peach, and grafting white orchid. Summer is also a suitable period for sowing some potted flowers, such as sowing three-color sage in July, which can bloom around the National Day. Sowing chrysanthemum in July and August can bloom during the winter season with few flowers. Sowing cyclamen and carnation in August and September can bloom the following summer.
