1、 Watering principle

Dahlia is neither drought resistant nor wet resistant. It likes neither dry nor wet. Its root belongs to fleshy root and is sensitive to water. Therefore, it should keep dry and wet when watering at ordinary times. Water cannot be lacked in normal growth. Insufficient watering will lead to water shortage and wilting. Each watering should be thoroughly watered to ensure that the root can absorb water. If there is too little water, the root is still relatively dry. Too much water will make the root unable to fully absorb, and then there will be ponding, and even lead to poor drainage, leading to root rot, and in serious cases, the whole plant will die

2、 Water quality requirements

In terms of water quality, there are not many requirements. General tap water can be used for watering, but it can't be poured out. It needs to be left standing first, so that the chlorine can volatilize and won't harm the root system

3、 Watering method

Prepare water before watering, and then water it slowly along the edge of the flowerpot to make the soil penetrate slowly. Don't splash it on the leaves and flowers, which may cause the flowers and leaves to rot

4、 Ponding treatment

Dahlia cannot be watered more. Once there is ponding after watering too much, it should be treated in time. First stop watering, then loosen the soil properly and put it in a ventilated and cool place
