Emptying a pot with regrowing flowers
With most of the flowers, once you cut all the flowers in a pot, the pot will become automatically empty. You can also tap on a flower and select the “Trash all” button to empty it.
Some flower types will grow new flowers as older flowers are cut. You can tell this kind of flowers have a green tag instead of the regular yellow one. The only way to empty a pot of flowers with this property is to use the “Trash all” icon.
If all the flowers have been recently cut and they aren’t sprouting out of the ground, tap a few times on the dirt until you hit one of the seedlings under the soil. You’ll get the same menu and you can select “Trash all” to empty the pot.
