You need to know how to care for mini succulent gardens. Check for dry, yellow or falling leaves to see if the plants are not getting enough moisture. Make sure the plant is mature enough to bloom. Drenched soil leads to plant rot; make sure to use a pot with at least one draining hole and a saucer underneath. Succulents need soil with good drainage. After the plant has been in the same potting mix and pot for more than a year, I start fertilizing it. The plant isn't thriving as well. The roots are only 1.5 cm deep. Therefore, the rainwater doesn't take too long to reach them.
