'''Layering''' is a technique for [[plant propagation]] in which a portion of an aerial [[stem]] is encouraged to grow [[root]]s while still attached to the parent plant, and then removed and planted as a new plant.

The process typically involves wounding the target region and optionally applying [[auxin|rooting compound]]s.  In '''ground layering''', the stem is bent down and the target region buried in the soil.  In '''air layering''', the target region is surrounded in a moisture-retaining wrapper such as [[sphagnum moss]], which is further surrounded in a moisture barrier such as [[polyethylene]] film.  In either case, the rooting process may take from several weeks to a year.

Layering is more complicated than taking [[cuttings]], but has the advantage that the propagated portion can continue to receive [[water]] and [[nutrient]]s from the parent plant while it is forming roots.  This is important for plants that form roots slowly, or for propagating large pieces.

1. Name at least five house plants raised for their foliage.

2. Name three house plants raised for their flowers.

3. Name three house plants adapted to direct sunlight, dry soils, and very moist soils.

4.Most house plants like a 65-to 75-degree (18 C - 22 C) temperature. Name one that requires a cool room (45 to 55 degrees F.) (7 C - 13 C).

5.Prepare a special potting mix soil including at least 3 different ingredients. Select two house plants from requirement two and grow them in this soil for three weeks.
