Alligator Plants should be considered low-maintenance succulents and should be a regular part of any houseplant enthusiast’s collection. It wilted within 24 hours and half of my alligator plants turned black and died. The house has many plants. Outside, there are potted plants. Small succulents can be kept in small pots for as long as a few weeks, months or even years. If you see that your plant has a mealybug infestation, you can clean up your plant using rubbing alcohol.
