Watering bonsai is very important, especially in winter. Not only must pay attention to the way of watering, the amount of watering but also pay attention to the time of watering.
1. Water the bonsai in a sunny morning
After the weather turns cold, you should water your bonsai in a sunny morning. The reason for not watering at night is because the night temperature is low, leaves, branches and soil easily retain water after watering.
Thus, the soil that remains wet will not be good for the growth of the plant’s roots. Water-soaked roots can easily lead to root suffocation, which can easily lead to yellowing of leaves and root rot.
After watering at night, if the amount of water left on the leaves and branches is not evaporated in time, it will also easily lead to the proliferation of germs and insects, such as black spot disease, gray mold that often reproduces. in a humid environment.
And if the leaves regularly retain water, it is also susceptible to pests and diseases, such as common aphids, whiteflies and scaly insects.
2. Avoid using cold water to water bonsai
Watering at low temperature will make the bonsai fall into more severe frostbite. That’s why we insist that when watering, we should use clean water at room temperature instead of cold water.
Especially for indoor bonsai pots , the water temperature from the faucet is relatively low, the temperature of the potted soil will definitely be higher than that of tap water.
Therefore, watering during the day, the temperature of the tap water will be slightly higher. If you can get water into the pot first, let it dry in the sun (so that the water temperature is at room temperature) and then water the bonsai, it will be more beneficial for the growth of the plant.
3. Make sure that the potting soil of the bonsai is dry before adding water
This ensures that the potting soil dries below 5 cm before adding water to the bonsai. You should also not just water lightly with a little water, but have to water it thoroughly, making sure the whole pot is completely wet.
To do this, before watering indoor plants, check the dryness and wetness of the soil in the pot. At the same time, be knowledgeable about the water needs of the ornamental plants you grow.
4. Control water for bonsai when the temperature is low
After the temperature gradually decreases, the frequency of watering bonsai should be gradually reduced, especially after the growth of the plants slows down. The reason is, when the temperature is too low, bonsai gradually enter a state of hibernation that needs less water, especially tubers, so they should gradually stop watering.
Of course, potted plants in greenhouses, with high temperatures, will still grow normally and have normal water needs, you still have to regularly water them.
If the room is relatively dry, you should also find ways to increase the humidity of the environment such as spraying water around the plant or placing a pot of clean water next to the plant.
