The basal end of the cutting is dipped into the chemical prior to sticking it into the propagation medium. These products come in different strengths and will vary according to the type of plant being propagated. To take a tip cutting, select a section of stem with a healthy crown of leaves at the end. Carefully remove the lower foliage to leave a section of bare stem to insert into the propagation media. Bottom heat, provided by a heating cable, will encourage rooting.
Some plants root so readily from stem or tip cuttings they can be started in plain tap water.
The water must be kept clean and well aerated for best results. A bright location out of direct sunlight is best. After roots are formed plants should be transferred to individual pots, or grouped together in a hanging basket. Many plants with soft, fleshy foliage have developed the ability to reproduce themselves from leaves. Considering that some plants grow hundreds of leaves, you can appreciate the propagation potential for these species.
