Plant Propagation by Plant Rooting and Cuttings
A common way to grow new plants from existing ones, is by taking cuttings
and rooting them, most often in water. It is generally known as plant "rooting"
or "growing cuttings". Rooting new plants from cuttings is possible on a
wide range of houseplants, bushes and shrubs. For bushes and shrubs, if the
stems are soft wooded, chances are they can be rooted to grow new plants.
The list is long, and includes popular plants like Roses, Lilacs, Pussy Willows,
Rose of Sharon, and many more. I always tell growers when in doubt, give
it a try.
Did You Know? Some plants, like African Violets, work well with leaf
cuttings. The leaf is either placed in water to root, or placed directly
into moist soil. Some leaf cuttings will grow pinned to the surface of the
soil. The new plants will root from the veins where they contact the moist
Rooting new plants is easy. Most plant rootings are done in water. The most
notable exception is roses, which are rooted in moist soil. Here is how most
plants are rooted:
Select new, young sections of stems that are growing well.
Do not select old wood, unhealthy stems, or stems with flowers on them.
Cut the end section of the stem off with a clean pair of shears or
Remove leaves at the bottom of the stem that might be under water.
Immediately (and quickly) place the stems in water. An inch or two of water
is all that most plants will need.
Watch the water level to assure it doesn't dry up. Add water as needed.
After the cuttings have developed some roots, transplant them into their
new home in an indoor container, or outdoors in the garden or yard.
Note: Garden stores carry rooting compound. It aids root growth and development.
It is useful with older plants, and hard to root plants.
Did you know? Propagation by cuttings in a sense is "cloning". It
results in a genetic match with one mother (or donor) plant.
Seaweed fertilizer is beneficial for your young plants. It helps to promote
a healthy root system. More

Root separation, or division of roots, is a similar, yet different
way to propagate plants. This is commonly practiced with perennial flower
plants. Many perennial flowers spread by it's root system. They get over
crowded, and need thinning from time to time. Often, a friend seeds
the perennials expresses interest in some of the beautiful plants eager
to oblige a friend, gardeners will dig up and separate the roots, then replant
them, or give them to their friends.
