Watering formula of elm bonsai

Watering elm bonsai should follow the formula of "seeing dry and seeing wet" Generally speaking, water until the soil is completely dry. If the soil is still wet, don't water it at this time to judge whether the elm bonsai is dry. You can observe the soil surface. If it is found that the soil surface is white and dry, and the soil is slightly hardened, it means that the elm is short of water and can be watered normally. Dry-through watering: When watering elms, you should follow the formula of dry-through watering. When watering, water thoroughly until the bottom of the flowerpot can flow out, which will promote the infiltration of water in the soil and make the roots fully absorb water. Elm can't be watered only half, otherwise the roots at the bottom can't get water, and they are still in a state of water shortage and drought. At the same time, elm trees should not be watered too much, otherwise a lot of watering at the roots will lead to stuffy roots and rotten roots.
