The key to the maintenance of potted flowers in plum rain season

The climate phenomenon of continuous overcast and rain occurs in the south of China in June and July every year, because it is the mature period of Jiangnan plum, so it is called "Meiyu", this period is called Meiyu season. In the Meiyu season, Rain Water has many, high humidity, high temperature, and is prone to stagnant water, and plants in this Meiyu climate are easy to breed molds and harmful insects, although this is the rapid growth period of plants. however, with the change of temperature, most plants will appear dormant or semi-dormant state, which is not only a "challenge" for plants, but also a great test for the flower cultivation level of flower growers.

In such a bad Meiyu climate, how can we get through our love flowers safely?

The key to the conservation of potted flowers lies in rational watering, fertilization, ventilation, lighting, drainage and prevention of diseases and insect pests.

1. Watering

The best watering time is before 10:00 and after 4pm every day. If the temperature is above 30 ℃, water the plants as little as possible. If it is placed on the outdoor platform or hard ground, it is usually watered once a day, according to the actual situation, appropriately increase the watering times and water quantity, or spray water on the foliage surface to achieve the effect of humidification; if it is an indoor foliage plant, it does not need to be watered every day, see the basin soil dry and then water through, and pay attention to foliar spraying.

2. Fertilization

Fertilization should not be too much, especially unfermented human feces and urine, chicken manure, milk, soybean milk, fish offal and chemical fertilizer. For example, if the concentration of urea is not better than the concentration is too high, the roots will be cauterized, causing leaves and flowers to wither and blacken rapidly. Because the air is humid and microbes thrive during the rainy season, if you apply fertilizer indiscriminately at this time, it will cause the roots of the plant to rot because of too many microbes.

3. Ventilation

If you encounter a sudden rainstorm followed by a clear day after the rain, it is best to move the potted flowers to the ventilation place for shelter from the rain. if it is not easy to move, you can put up the bottom of the basin to remove the stagnant water plate and create drainage and ventilation conditions.

4. Lighting

After continuous rainy weather. In a sudden high temperature, avoid direct exposure after rain. As the branches of flowers are relatively tender, it is necessary to avoid sudden direct sunlight so as not to burn tender leaves and buds. Grass flowers such as Milan, Magnolia, rose and jasmine enjoy light, while indoor foliage plants such as rich trees, green pineapple, rattletail sunflower, zebra and evergreen can keep weak light. Shading should also be done for negative plants.

5. Drainage

Rain Water is continuous in the rainy season, and it is easy to breed mold, which is the "first enemy" of plants in the rainy season. For open-field plants, we should pay attention to strengthen inspection, whether open-field planting or potted plants should be timely drainage. See if there is poor drainage or local stagnant water. Lest the root of the plant suffocate and lead to rotten leaf root yellow. Once there is stagnant water in the flowerpot, you can use slender hard objects such as bamboo sticks to stick into the flowerpot several times. If the stagnant water is not removed in time, the plant may have rotten roots and suddenly "die" when summer comes.

6. Diseases and insect pests

Plum rain season is a frequent season of potted flower diseases and insect pests, the emergence of diseases and insect pests should distinguish between different situations of symptomatic application of drugs, which requires everyone to prescribe the right medicine, can not be used indiscriminately. The most common pests are red spiders, aphids, shell insects, etc., which can be sprayed with omethoate. Affected by high temperature and heavy rain, flowers and trees are most vulnerable to fungal infection, rose is also prone to black spot, powdery mildew and so on. Carbendazim is a general control agent. In addition, the concentration of pesticides used should not be too high so as not to burn the plants.

Of course, Meiyu is not necessarily harmful to plants, such as abundant Rain Water and suitable temperature will promote the growth of new leaves, conducive to plant cutting propagation, the survival rate will be higher and so on. For example, some potted rose, triangular plum, five-colored plum, green apple, tortoise back bamboo and so on are suitable for cutting culture at this time.
