Allow the cuts to dry out (callous) for a few days to avoid rotting. Pot it in its individual pot and place in a cool place. Maintain the soil moist through out until the new plant is well established.
Propagating String of Buttons Plant from leaf cuttings
Take String of Buttons Plant leaf cuttings. Allow the cutting to dry out (callous) for a few days to avoid rotting. Stick the lower cut end in moist free-draining soil. Place in a warm place and maintain the soil moist until there is new growth from the base of the cuttings. Allow substancial growth before transplanting the new plant.
Propagating String of Buttons Plant from stem cuttings
Take 3-5 in. of String of Buttons Plant stem cuttings. Allow the cutting to dry out (callous) for a few days to avoid rotting. Stick the lower cut end in moist free-draining soil. Place in a warm place and maintain the soil moist until they are rooted. Rooting may take about 4 weeks. Allow substancial growth before transplanting the new plant.
Brown leaf tips and edges in String of Buttons Plant are due to sudden drop in temperature from cold draughts. Remove all the damaged leaves and keep the plant away from cold draughts.
There are two causes of sudden loss of leaves in String of Buttons Plant. Either the temperature is too low; move to a warmer spot or the plant has been underwatered causing the leaves to drop.
Exposing String of Buttons to hot direct sunlight will cause the leaves to become dull and lifeless. Protect the plant from hot direct sunlight or move to a shaded spot.
