1. Cuttings are pieces of stem, leaf, or route that has been removed
from a plant to produce new roots.
2. Layering means treating a shoot (a branch, stem, or twig) or
forming new roots while still attached to the mother plant.
3. Bulbs and tubers or underground leaf buds or roots. These are
planted by separating or dividing the clamps of bulbs. When leaves of
bulbs turn yellow that is the time to dig and transplant them.
Hope this helps
