Place the offset into a small muckle with well - draining grime . Do not water until new ontogeny is note .
Leaf - cutting entail cutting a young leafage from near the center of the rosette . Leave the leaf in the open air for a Clarence Shepard Day Jr. to allow the injury to calloused . Next , duck the leafage into a rooting hormone and place the leaf ( cut - side down ) into a somewhat moist succulent potting commixture ( even better , very light dampish sand ) . presently , a new rosette will grow from the root of the leaf .

A root mealybug infestation symptom are slow or stopped growth ( though in summertime , this is a normal foretoken of sleeping ) . If this occur without patent cause , remove the plant from the pot and examine the roots . A white cottony essence on the roots and soil is a sure planetary house of mealybug infestation .
