Asexual propagation, as mentioned earlier, is the best way to maintain some species, particularly an individual that best represents that species. Clones are groups of plants that are identical to their one parent and that can only be propagated asexually.
Stem Cuttings:
This technique is probably the most versatile of all methods used for vegetative propagation. It can be used for both herbaceous and woody material. Herbaceous stem cuttings can be made from houseplants, annual flowers and bedding plants, ground covers, and some perennials.
Advantages of asexual propagation include: It may be easier and faster than sexual propagation for some species. It may be the only way to perpetuate particular cultivars. It maintains the juvenile or adult characteristics of certain cultivars.
Seed propagation is the most common method of sexual reproduction in plants. It involves planting seeds, which germinate to produce new plants.
Cuttings are the most common and easiest method of propagation. A part of a plant is simply cut off the parent plant and rooted. The rooted plant part then regrows and develops into an entirely new plant. Taking cuttings is easier than growing from seed and cuttings flower and mature faster than seed propagation.
Some plants produce roots super fast, within a week or two, some take 4 to 6 weeks or longer. Heat and light both help with warmth being a key factor (which is why propagating in winter is more difficult), and a rooting hormone like Clonex definitely speeds everything up.
Cuttings. Cuttings can be made using a leaf or stem. This method is the most common and considered the easiest way to propagate plant material.
You can propagate with seeds or roots, but the easiest and most common method is by cutting, or transferring a piece of a mature plant into water or soil and letting it grow a new root system. Propagating with cuttings offers a lesson in plant biology.
Propagating by saving and sowing seed
Growing plants from seed is one of the cheapest and most effective ways of propagating plants.
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.
Propagation for many plants is best done in potting soil, but some plants can be propagated in water. This is because they have evolved in an environment that allows it. Most Aroid plants can be propagated in water, including pothos plants, philodendrons, monsteras, and ZZ plants.
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.
The major methods of asexual propagation are cuttings, layering, division, budding and grafting. Cuttings involve rooting a severed piece of the parent plant; layering involves rooting a part of the parent and then severing it; and budding and grafting is joining two plant parts from different varieties.
The technique you select will depend on the type of plant you wish to propagate and the amount of time and effort you want to put into it. The simplest method is planting seeds; division & stem cuttings are fast; and with layering, there are almost no failures.
The best time to take softwood cuttings is from mid-spring to early summer. Hardwood cuttings are taken later in the year, from mid-autumn to mid-winter.
There are two types of propagation, sexual and asexual. Sexual reproduction is the union of the pollen and egg, drawing from the genes of two parents to create a new, third individual. Sexual propagation involves the floral parts of a plant.
HEARTLEAF PHILODENDRON & GOLDEN POTHOS (Philodendron hederaceum & Epipremnum aureus) When it comes to setting off on your propagation journey there are no better plants, to begin with, than the Heartleaf Philodendron and Golden Pothos. Not only are they fabulously easy to propagate but are highly rewarding too.
Willow is good for rooting cuttings because it contains high concentrations of Indolebutyric acid (IBA), and also salicylic acid, from which aspirin is derived and which protects against fungi and other pathogens. To make willow water, simply gather around 2 cups of fresh willow growth chopped up into short lengths.
The cuttings will begin growing roots from the nodes within a week, and the cuttings will be ready to plant in pots within 3 weeks! Sometimes some cuttings are slower, though, so just keep those in water until the roots are about as long as the cutting itself.
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. This plant has heavy rooting and is ready to be moved to a pot with potting soil.
Water propagation (Most Common)
Short form Summary: Place your new cutting into a jar (preferably a glass jar) filled with cool/tepid water and wait until you notice white roots appearing. When the roots reach around a half-inch long, remove them from the water and plant them in fresh moist potting soil.
Petiole. The petiole attaches the leaf to the stem. Sometimes the petiole can look like a stem, but it is actually part of the leaf. Petioles can be long or short, wide or narrow!
