You may have noticed that conventional flowerpots, whether made of clay or plastic, always have a projection at the top of the pot (often called a shoulder or collar), but I’ll bet you didn’t know that this collar is not just a decoration, that it is actually designed to show how far to fill the pot with soil when you repot?
If you fill the pot with soil to its collar, but no further, when you water in the future, you can simply fill the empty space on top of the soil with water. It was designed to hold exactly the amount of water required to saturate the soil the pot contains, fully yet without overflowing… a neat little trick that can make watering much easier!
