How to propagate plants by rooting stem cuttings
There are many ways to propagate indoor plants, but we'll talk about a simple and easy option.
And so, the best way to propagate plants is by stem cuttings.
You will need to place the cuttings in water or growing medium until they develop roots, and then plant the rooted cuttings in pots or in the ground. Unlike propagation by seed harvested from the parent plant, cuttings ensure that new plants are genetically identical to the parent plant. (In the case of hybrid plants, propagation with harvested seeds may result in plants that differ in appearance).
The plant propagation method by rooting with stem cuttings is a very common way to create new houseplants, but it can also work for many garden species.
For example, in cold climates, many growers take cuttings of tender annuals and root them indoors so they can stock up on new plants in the spring to plant in the garden.
Propagation by rooting cuttings is most successful for soft-stemmed herbaceous plants, but many woody plants also lend themselves to this method.
1. At what time are stem cuttings taken.
They can be rooted mainly at any time, especially during the period of activity of the parent plant.
And also, this is an additional way to expand the plants.
In colder climates, you can use this method for replanting in the spring.
Let's say you can make cuttings from tropical coleus plants in the fall before the first frost and root them indoors. In spring you will have potted plants that you can later place in the garden.
The method of rooting stem cuttings for gardeners seems to some extent painful, since it is not suitable for all plants, only luck will decide.
Many types of annual herbaceous and indoor plants are well suited for this cultivation and as a result, the result is rapid maturation.
Cuttings of perennial and woody plants such as shrubs are often more difficult to root and may take longer to mature.
The key to successful rooting of cuttings is an accurate indication of the moisture and temperature levels that are appropriate for each type of plant.
You need to do a little research on the species you are trying to breed to find out what conditions are right for them. Making a few cuttings is a great option to maximize your chances of success.
Most plants propagate by rooting cuttings in a container of plain water. But the transfer of a seedling with watery roots into the soil itself may not succeed, therefore, it is better to place the cutting in the soil mixture in order to root.
It is important that the potting mix remains moist, but not soggy.
3. Finding the best stems for cuttings.
The best choice for cuttings is green, non-woody stems. New shoots take root better than old ones.
We need a stem with a knot (a protrusion along the stem where a leaf or flower bud is attached), the place where the roots will appear.
4. Take a cut of plants.
Thanks to the instrument (scissors), which is sterilized in alcohol, make a clean cut below the knot.
The cutting should have a minimum of 2 leaves and 1 knot and a short length.
A length of 4 to 6 inches is sufficient.
If the stalk is long, then it can dry out indoors in a nutrient medium.
5. Preparing the incision.
Place the incision on a flat and hard surface and make a clean parietal incision in the middle of the assembly with a sterilized razor blade. This will increase the likelihood of roots emerging from that location.
Remove everything from the cuttings except 1 or 2 leaves.
To continue photosynthesis of the cuttings, the development of leaves is necessary, you can leave some leaves.
Rooting fertilizer stimulates the growth of cuttings to the emergence of new roots.
Fill one container with water and add a little rooting hormone to the other container.
Dip the end of the cutting into water and then into the rooting hormone.
7. Make a hole for planting.
Use a sharp object to pierce the planting hole in the potting soil. When the hole is larger than the diameter of the stem, this is a reason to prevent the excretion of the rooting hormone when the plant is in the pot.
8. Planting the cuttings.
Place the cutting into the hole and gently tamp the soil around.
You can place several cuttings in one container, but the main thing is to arrange them so that the leaves do not touch each other.
9. Cover the pot with plastic.
Place the pot with the shank in the bag, this will keep warm and damp. Leave a small gap in the bag to prevent rot.
Store in a warm place where filtered light penetrates. Only when the leaves begin to form will sunlight be needed.
Until the roots have formed, it is necessary for the soil to be slightly moist and remove all suspicions.
After 2-3 weeks, check for the presence of roots. Then you can already start planting a plant in a flowerpot or ground.
