After September, keep in mind three things you can't do, or you'll have problems.

Now it has entered September, indicating that autumn has gradually come. Although autumn is the peak growing season for flowers, the root system of most plants will become weaker in autumn, and both the growth ability and speed will slow down. Therefore, in order to make flowers grow healthily and safely through the winter, three details must be paid attention to in autumn flower cultivation.

1. Don't apply fertilizer blindly. Because the root system is fragile in autumn, it is not as developed as in spring and summer, so fertilizing flowers should be very cautious. The slightest carelessness will burn the plant roots. However, it is still necessary to apply fertilizer when it is time to apply fertilizer, not to use it blindly. Do not use too much fertilizer, do not use immature fertilizer, and stay away from the root system. If the plant grows well, there is no need to apply fertilizer. For some weak plants and diseased plants, we should not apply fertilizer blindly, otherwise, it is easy to make these plants die.

2. Don't change the basin and soil at will. In autumn, the roots of plants grow slowly and become old, and new roots can not be sent out in time after changing pots, and the ability of old roots to absorb water and nutrients is very weak. At this time, plants can not change seedlings for a long time, especially when changing pots, the roots are most vulnerable to injury, and it is difficult to recover after injury, which is most likely to cause withering, decay or death. Therefore, it is best not to change the soil in autumn, but also wait until spring, when the root system is developed and the growth is exuberant, which is the best season to change the soil.

3. Don't water casually. In autumn, due to the dry climate, the plant grows fast and needs plenty of water. However, at this time, the root system is very sensitive to temperature, and the temperature of the tap water just released is very different from that of the soil. If it is directly poured into the flowerpot, the root system will be affected by the change of hot and cold temperature, which will accelerate its aging and seriously cause root rot. Therefore, it is necessary to put the water for a period of time or dry for a while, and then water the flowers when the temperature of the water is about the same as that of the soil, so that the root system will not be hurt and it can save more nutrients safely through the winter.
