There’s no hard and fast rule when it comes to watering plants. Some plants need their soil to stay evenly and consistently moist and will need to be watered more frequently. Others like their soil to dry out completely before being watered again. Always do your research and check the tag that comes with your plant to learn about its specific needs.
A general rule of thumb is that if the soil is dry to the touch when you stick your finger in it an inch deep, it’s time to water again.
