They are beautiful but not practical for succulent planters. Aloe Cilicaria is a tall, sprawling succulent that can climb palm trees trunks. Tree aloes may look less attractive in winter because they are slow to grow. While leaves can become yellowed or have black spots, they will turn greener with the help of summer warmth and food. Take a pair or sterile knife and remove any stems from the main plant. After allowing it to become callus for several days, place it in well-draining soil. A few easy steps can be taken to propagate your existing succulent collection.
