Propagate your Burle Marx through stem cuttings or air layering. For a stem cutting, cut the stem an inch or two below a leaf node and either place the cutting directly in water or cure the cutting for 7-10 days and then pot in well-draining soil. For air layering, wrap a leaf node in damp moss and cover the moss in plastic. Check the moss weekly, keeping it damp and watching for signs of root growth. Once roots are 2 inches long, cut below the leaf node and plant in well-draining soil.
