Five key points of flower cultivation management and maintenance in summer: flood, big fertilizer, seize the opportunity to promote growth

The vigorous growth period of most flowers in summer is also the golden period of flower cutting. However, summer is also a season with hot climate, abundant rainfall and a large number of diseases and insect pests, so we must pay attention to strengthening management.

1. Appropriate cooling

Summer is the midsummer season, the sun is hot, many flowers do not adapt to this high temperature, sunny flowers also need proper shading around noon.

2. Watering in time

Due to the high climate in summer and the rapid evaporation of water, it needs to be watered in time. However, it should not be watered at noon in direct sunlight, preferably once in the morning and evening. It is worth noting that all kinds of flowers have different requirements for water. Large-leaf and thin-leaf flowers can be watered more, while cactus, lobular and coniferous flowers can be watered less because of their small water evaporation. Summer watering should also be flexible according to the weather conditions, hot weather should be watered more, cloudy days should be less watered, rainy days should not be watered. The degree of dryness and wetness of the basin soil should also be observed to determine whether to water more or less or not. In the case of continuous rain in summer, should also be appropriate to cover the rain or tilt the basin, so that stagnant water is discharged in time to prevent rotting roots.

3. Timely fertilization

Flowers grow fast and consume a lot of nutrients in summer, so they need to provide sufficient fertilizer in time. But fertilization in summer should also be treated differently according to different flowers. General potted flowers can be treated with mature dilute liquid fertilizer every other week. For flowers in acidic soil such as camellia, rhododendron and poinsettia, dilute alum can be applied every other week. Fertilizing water should be carried out when the soil is relatively dry, and loosen a basin of soil before fertilization, so that the roots of flowers can be fully absorbed. When fertilizing, you should also avoid touching the leaves with fertilizer and water, so as to prevent damage to the leaves. Remember to water once the next day. Fertilization is best carried out in the evening.

4. Pruning

Flowers grow rapidly in summer, and the overgrown branches and leaves that affect the beauty of the tree shape and blossom and fruit, the cross branches that affect ventilation and light transmission, the overgrown branches, dense branches, and diseased branches need to be cut off in time. When some spring-sown flowers grow to a certain height, they should be coring in order to promote them to have more branches and blossom; for some woody flowers, when their branches grow to nearly 20 centimeters, they also need to pick their hearts, so that they can sprout more new branches and increase the number of flowers. There are some adventitious buds on the branches, which will destroy the flower shape and should be removed in time. For ornamental flowers, such as chrysanthemum, dahlia, peony, etc., part of the excessive buds and lateral buds should be removed to make the flowers large and colorful; for ornamental flowers, such as pomegranate, bergamot, etc., part of the young fruit should be removed in time, so that the fruit can be large and plump.

5. Cutting sowing

Summer is a good time for evergreen flowers and trees to be cut. Some annual herbaceous flowers, such as pansy, melon and leaf chrysanthemum, can also be sowed in summer, sown in July and blossom after National Day.
