Petunia water requirements

1. Do you like water?

Petunia is relatively water-loving. Its underground roots are very developed and there are many leaves on the ground. Therefore, when the light is good, the transpiration is very obvious and the water demand is very large. Be sure to ensure sufficient moisture and water more frequently when the plant needs water during the growing season. If there is a lack of water, the old leaves underneath will become dehydrated and turn yellow.

2. Watering frequency

During the spring and autumn when the climate is more suitable, you can water it every 3-5 days. At this time, water is indispensable for growth needs. In summer, evaporation increases and watering is required twice a day, once in the morning and once in the evening. With the arrival of winter, the temperature gradually drops and the growth rate slows down. You can water the plant every 7 days or so, and do not water it unless the soil in the pot is dry.

3. Proper water control

Not all periods require sufficient water. Some periods require appropriate water control. For example, do not water too much when the plants are first planted. Water control is also needed about 7 days before transplanting to maintain a certain degree of dryness.

4. Watering principles

Although petunias like water, you should not water them too much each time and do not allow water to accumulate. Just make sure they are watered thoroughly. If you cannot control the amount of watering at this time, you can observe a little water flowing out from the bottom of the pot, or weigh the pot to feel the water content in the soil.
