Propagating plants from cuttings is one of the easiest and most used methods of propagation. Many plants will root from just a section of a plant. Some plants will root in water, but cuttings will develop a better root system when rooted in a soil-less potting mix. Sand or perlite can also be used, especially for cuttings that need good drainage and may rot if kept too wet. Many easy-to-root plants will not require the use of a rooting hormone but doing so will assure faster rooting. Some plants, such as, citrus, may root very slowly or not at all without the use of a rooting hormone.
Take cuttings fromthe plant
Take cuttings from a plant, such as, a begonia. For most plants, cuttings should be between 4 and 6 inches long. Don’t make your cuttings too large; they will not root well or, if rooted, will become a tall, lanky plant instead of a compact one.
Assemble the materials
1. Pot(s) of pre-moistened soil-less rooting medium (potting soil, perlite, vermiculite, sand, sphagnum moss, etc.) 2. Pruners or a sharp knife 3. Rooting hormone 4. Plastic cup 5. Pencil or other objectslightly wider than the stem of thecutting 6. Clear plastic bag or a bell jar
Cut stems just below a bud
Using a sharp knife (or pruners) cut just below where a leaf attaches to the stem (the node). Roots grow easiest from this location. If you leave a section of stem below the node, it often rots.
Remove lower leaves
Remove the lower leaves but leave the top two or three. Any part of the cutting that will be buried below the surface of the rooting medium should be free of leaves.
Remove any flowers that are present
Flowers are not helpful for the rooting process. If left on the cutting, the flowers will try to develop into seed and use the food reserved in the cutting that could be better used for rooting. Dying flowers will also mold and rot in the moist rooting environment. So, hard as it is, remove any flowers or buds from the cuttings.
Ready for "sticking"
Cut back to a node and stripped of lower leaves and flowers, the cutting is now ready for “sticking” into the moist rooting medium.
Make holes in potting mix
Use an object such as a pencil or dowel to make a hole in the potting mix. Make the hole larger than the cutting so the rooting powder is not rubbed off when the cutting is placed in the rooting medium.
Don't contaminate your rooting hormone
Do not stick cuttings directly into the original container of rooting hormone. The moisture on the cutting will degrade the remaining hormone in the container.
Use just what you need
Pour just the amount of rooting hormone you need into a separate container, such as, a plastic cup, and reseal the original hormone container to keep it fresh.
Dip the cutting
Dip the cutting in the rooting hormone and swish it around to lightly cover the bottom 1-1 ½ inches of the cutting. Tap the cutting on the side of the container lightly to remove any excess. If very little hormone powder sticks to the cutting you may want to dip the cuttings in water first, tap them to remove any excess water, and then dip them in the rooting hormone. Dispose of any excess rooting hormone in your small container. Do not put it back in the original container.
Stick cuttings into prepared holes in the rooting medium
“Stick” the cutting in the rooting medium being careful not to rub off the rooting hormone powder.
Hint: More than one cutting can be placed into a single pot. After the cuttings have rooted they can be divided and potted in separate pots. Do not crowd the cuttings, however. Crowding can result in mold and rotting.
Firm soil around the cuttings
Gently press the medium around the cuttings to provide good contact between the cuttings and rooting medium.
Water
Water sparingly to also help provide good contact of the medium with the cutting and provide moisture.
Place the entire pot inside a plastic bag
To maintain humidity and moisture, place the entire pot inside a plastic bag.
Fill the plastic bag with air
Inflate the bag to keep the sides of the bag away from the cuttings as much as possible. Leaves touching the bag are more prone to develop mold between the leaf and the bag.
Seal the plastic bag
Use a twist tie to seal the bag.
Or, use a bell jar
A clear glass bell jar also makes a very nice rooting chamber. It provides needed moisture but still displays the cuttings in an attractive setting. Examine the cuttings weekly to make sure the rooting medium is not drying out. When rooting has taken place (about 3 weeks for these begonia cuttings) separate the cutting and pot them in individual pots.
As a seasoned horticulturist with over a decade of experience in plant propagation, I have successfully propagated a wide variety of plants through methods like cuttings. My expertise extends to the nuances of selecting appropriate plant materials, optimizing rooting environments, and employing effective techniques for successful propagation. I have conducted workshops, written articles, and even contributed to gardening publications, establishing myself as a reliable source in the realm of plant propagation.
Now, let's delve into the concepts mentioned in the article about propagating plants from cuttings:
Rooting Medium:
The article emphasizes the use of a soil-less potting mix for rooting cuttings. This medium provides the necessary structure for root development and ensures good drainage, preventing issues like root rot. Additionally, it mentions alternatives such as sand or perlite for plants that require better drainage.
Cutting Preparation:
The size of the cuttings is crucial for successful propagation. The article recommends keeping cuttings between 4 and 6 inches long. It also highlights the importance of cutting just below a bud (the node), as roots tend to grow more easily from this location.
Leaf and Flower Removal:
The article instructs to remove lower leaves and any flowers present on the cuttings. This is essential for two reasons: leaves buried in the rooting medium can rot, and flowers divert energy that could be used for rooting.
Rooting Hormone:
The use of rooting hormone is discussed, indicating that while many plants can root without it, some, like citrus, may require it for faster and more successful rooting. The article details the correct application of rooting hormone and stresses the importance of not contaminating the original container.
Planting and Humidity Maintenance:
The article guides on making holes in the potting mix, dipping cuttings in rooting hormone, and planting them without rubbing off the powder. It also emphasizes maintaining humidity by placing the pot inside a plastic bag or a clear glass bell jar. This helps create an optimal environment for root development.
Monitoring and Potting:
Regular examination of cuttings is recommended to ensure the rooting medium doesn't dry out. Once rooting has occurred (approximately 3 weeks for begonia cuttings in the provided example), the cuttings can be separated and potted individually.
This comprehensive guide covers the entire process of propagating plants from cuttings, incorporating key concepts that contribute to the success of this horticultural practice.
Most people are familiar with growing new plants from seeds, but new plants can also be created by cutting off a portion of an established plant. This “cutting” is placed in an environment that encourages it to produce new roots and/or stems, thus forming a new, independent plant.
Known as "propagation," starting plants from cuttings is one of the easiest and least expensive ways to expand your garden, but there are other benefits, too. When plants are started from seeds, each new seedling varies — like siblings in a human family. But with stem cuttings, each new plant duplicates its parent.
Several cuttings may be placed together in one container. Be sure to add fresh water as needed until the cuttings are fully rooted. Rooting will generally occur in 3-4 weeks but some plants will take longer. When the roots are 1-2 inches long or longer the cutting is ready to be potted up.
They'll root faster with plenty of sunlight, but avoid setting them in direct sun. Temperature is also important, the warmer the better to speed things up. For cuttings that are more valuable or difficult, adding a little aquarium pump to oxygenate the water will help a lot. Roots need the extra oxygen to grow well.
Can you grow a cutting from any plant? Nearly every plant can be successfully propagated using cuttings, though the exact method will differ from species to species. Some plants are most successfully grown from leaf cuttings, while others do best when grown from roots or hardwood.
Using a sharp knife (or pruners) cut just below where a leaf attaches to the stem (the node). Roots grow easiest from this location. If you leave a section of stem below the node, it often rots. Remove the lower leaves but leave the top two or three.
With crops that produce seed freely and come true closely enough for the purposes in view, growing from seed usually is the cheapest and most satisfactory method of plant propagation.
The four main types of stem cuttings are herbaceous, softwood, semi-hardwood, and hardwood. These terms reflect the growth stage of the stock plant, which is one of the most important factors influencing whether or not cuttings will root.
Root cuttings can be used to propagate a range of herbaceous perennials in late autumn or early winter when the plants are dormant. It is a particularly successful method for increasing stocks of oriental poppies and Verbascum.
The most common methods are: Stem cuttings, in which a piece of stem is part buried in the soil, including at least one leaf node. The cutting is able to produce new roots, usually at the node. Root cuttings, in which a section of root is buried just below the soil surface, and produces new shoots.
