1. Do a good job of drainage pipeline.
There are many flowers of flower lovers in the yard. When it rains, they will be drenched, and occasionally the flowers will be drenched, and the state will be better. However, the continuous rainy weather will have an impact on the growth of flowers, especially when placed outdoors, flowerpots are easy to accumulate water, which makes the roots of plants unable to breathe normally, and yellow leaves will appear in a few days, which will damage the roots and seriously cause root rot.
On rainy days, it is best to move those flowers that are afraid of rain indoors to shelter from the rain, such as longevity flower, crab claw orchid, cyclamen, golden bell and cactus.
Drain the water in time after every heavy rain, dump the accumulated water in the flowerpot and the water in the tray below. Don't leave this stagnant water in the flowerpot for a long time, otherwise it will do harm to the flowers.
2. Reasonably reduce irrigation
Even in rainy days, potted flowers at home don't need to be watered more. If there is no sunlight, the water loss will be slow, and if it rains outside, the water will be too rich. At this time, it will not be watered again, which is more likely to cause waterlogging and lead to yellowing of potted flowers.
If there are many small dewdrops on the branches of potted plants after rain, shake them off or wipe them off. Because there are water drops on the branches, if the sun shines on them, it will cause condensation, which will easily burn the leaves and leave many embarrassing focal spots.
3. Temporarily suspend fertilization
Continuous rainy days, if potted flowers can't see the sun for a long time, it is also unfavorable for growth. Plants and flowers need photosynthesis to produce nutrients, so potted flowers can't see the sun for many days, and the situation is very poor, so it is easy to grow.
But this time is not suitable for topdressing. The original bonsai soil is too wet, the roots are weak and the absorption is poor. If fertilizing again, it will easily lead to phytotoxicity, burn the roots, and eventually the roots will rot, making the leaves yellow and gradually fall off.
4. Keep good natural ventilation in the natural environment.
On rainy days, potted flowers are in poor condition, grow slowly and their immunity is reduced. At this time, it is easier to feel pests and diseases, especially in the environment with poor natural ventilation. The soil of bonsai is wet and cold, which is very easy to breed bacteria and cause some pests and diseases in potted flowers.
Because at this time, there is moisture everywhere, so it is very important to let the natural environment naturally ventilate. Don't put potted plants in an overly closed environment, but always keep the natural environment naturally ventilated, so as to keep potted flowers in good condition and reduce the occurrence of pests and diseases.
In summer, the temperature is high, the light is high, and there is not much precipitation. When there is continuous rainy weather for a long time, it will also have a great impact on the growth and development of flowers and plants. Be sure to give it four things to reduce the occurrence of yellow root rot and withering of potted flowers.
