1、 Do you like water

Petunia likes water. Its underground roots are very developed and there are many leaves on the ground. Therefore, when the light is good, the transpiration effect is obvious and the water demand is very large. Be sure to ensure good water. When you need water during the growth period, you should water more. If you lack water, the old leaves below will be short of water and yellow

2、 Watering frequency

In the spring and Autumn period when the climate is more suitable, water can be poured every 3-5 days. At this time, in order to meet the needs of growth, there can be no lack of water. The evaporation increases in summer and needs to be watered twice a day, sooner or later. With the arrival of winter, the temperature gradually decreases and the growth rate slows down. You can water it every 7 days or so. If the basin soil is not dry, you don't need to water it

3、 Proper water control

Not all periods need sufficient water, and some periods need proper water control. For example, watering should not be too much at the beginning of planting. Water control is also needed about 7 days before leaving the nursery to keep it dry

4、 Watering principle

Although Petunia likes water, it should not be watered too much every time. It can not produce ponding. It can be watered thoroughly. At this time, if you can't master the watering amount, you can observe a little water flowing out of the basin bottom, or weigh the weight of the flowerpot to feel the water content in the soil
