The act of separating a houseplant into two or more halves is precisely what it sounds like. The spring season is the ideal time to divide indoor plants since they have emerged from dormancy and are prepared to begin growing once more. Plants that naturally generate offsets, such as Spider Plants and Sansevierias, are the simplest to divide.
- To begin, take the plant out of the pot and look at the root system. Choose the most appropriate division points. These are typically places where the roots are strong.
- Cut the plant into portions using a sharp knife, being careful to leave the roots in tact.
- The divisions should be immediately replanted in fresh potting soil at the same depth as before. Place the divisions in a warm area with bright, indirect light, and water them. Once established, fresh growth ought to begin to appear.
Can indoor plants be multiplied at any time of year?
Stem or cane cuttings can be used to multiply many houseplants. Pick non-flowering stems if you’re planning to utilize a stem cutting, and do it in the spring or summer.
After being removed from the main plant, the bulk of cuttings should be gently placed into the compost. If you’re using cuttings from cactus or succulent plants, allow them to dry out for at least a few hours to a day. This helps to seal the raw “cut” and lowers the risk of rot developing.
Cane cuttings are a wonderful option when you want to stimulate new shoots to emerge lower down but the cane has lost its upper leaves, the crown is dying, or the plant has a tall but unattractive “leggy” appearance.
You must make sure the cane is still pointing upwards to mirror the direction it was growing when it was attached to the main plant. To remove the cane, simply cut it into pieces that are at least 2 to 3 inches long (how many cuttings you get per cane will therefore depend on how long it is to begin with).
When should plant propagation begin?

A superior matrix of decomposed organic material held together by plant-derived polymers can be found in General Hydroponics Rapid Rooter. Ideal for ALL applications involving soil and hydroponics.
Use a blend of 80% organic potting soil and 20% perlite to transplant your little young shrubs into larger pots. A liquid organic fertilizer made of kelp or seaweed that is mixed with water. Before relocating plants outside, gradually “harden off plants. Find out here how to harden off plants.
Hardwood stem cuttings are collected when the plant is dormant and the tissue has become woody. The optimal time to harvest hardwood cuttings is in the late fall or anytime following a killing frost.
Look for stock plants that are thriving, healthy, and growing in direct sunshine. Again, the ideal stems are those that are neither too thin nor too thick. It is advised to have a minimum girth of 1/4 to 1/2 inch and a length of 4 to 8 inches. A few inches below the terminal bud is the ideal location for cuttings. Use a straight cut just above a bud on the top end of the stem and an angled cut just below a bud on the bottom end of the stem. Throw out the shoot’s tip. Always take more cuttings than you anticipate needing because some of them might not take root.
The straight cut, the heel cut, and the mallet cut are the three different kinds of hardwood cuts. (See Plant Propagation by Stem CuttingsFigure 3 for a diagram of each.) Most frequently, a straight or basic cut is employed. A small portion of earlier wood is present in the heel cut, while an entire older stem section is present in the mallet cutting.
Place the stems 2 to 6 inches apart in a container filled with a damp soilless potting mix after dipping the cut ends in rooting powder. So that just the top one or two buds are visible above the mix, bury the stems deeply.
Tip: Bury the angled cut into the pot to ensure that the stems are planted upward (the straight cut should be on top).
The cuttings should be watered, covered with a plastic bag, and placed in indirect sunlight. If they are regularly misted, rooting will happen faster. Remove the plastic covering from the young plants and move them into a larger pot or a covered bed once they have produced a good number of roots and some top growth. Wait until the beginning of the following season, when your plants will be much bigger and stronger, before planting directly in the landscape.
Leaf Cuttings
Leaf cuttings can be used to grow a variety of herbaceous or woody plants, including many indoor houseplants. By using a leaf and its stem (petiole), or occasionally just a portion of the leaf, one can start a brand-new plant. The procedures for propagation by leaf cuttings can be carried out at any time of year and are essentially the same as for softwood or hardwood stem cuttings.
Can indoor plants be propagated throughout the winter?
Have you ever wondered if you may reproduce plants in the winter when performing a winter dormancy pruning? It is possible to propagate in the winter. Try reproducing plants from the cuttings in the winter instead of throwing them in the compost or yard trash bin.
What time of year is ideal for cutting propagation?
In general, cuttings should be made from the most recent or current season’s growth. If at all possible, stay away from items containing flower buds. When preparing cuttings, remove any flowers and flower buds so that the energy of the cutting can be used to produce new roots rather than blossoms. Take cuttings, ideally from the top of the plant, from healthy, disease-free plants.
Rooting may be influenced by the stock plant’s (parent) reproductive state. Avoid taking cuttings from plants that exhibit signs of nutritional deficit in minerals. On the other hand, plants that have received a lot of fertilizer, especially nitrogen, might not root properly. There shouldn’t be any moisture stress on the stock plant. Cuttings from young plants typically root more frequently than cuttings from older, more mature plants. Often, lateral shoot cuttings take root more readily than terminal shoot cuttings.
Because the plant is fully turgid in the morning, this is the ideal time to take cuttings. The cuttings must be kept cool and moist until they are adhered. Cuttings can be kept in an ice chest or a dark plastic bag with moist paper towels. If attaching cuttings will take some time, put them in a plastic bag and put the bag in the fridge.
Even though the tastiest parts of the stem are the terminal ones, a long shoot can be cut into many cuttings. Typically, cuttings are 4 to 6 inches long. Use pruning shears or a pocket knife with a thin, sharp blade. To avoid spreading infections from diseased plant parts to healthy ones, immerse the cutting tool in rubbing alcohol or a solution of 1 part bleach to 9 parts water, if necessary.
Leaves should be taken off of the lower third to half of the cutting (Figure 4). To save space and lessen water waste on large-leafed plants, the remaining leaves may be chopped in half. Species that are challenging to root should be hurt.
Some plants that could be hard to root without assistance can benefit from root-promoting treatments applied to cuttings. Before handling cuttings, place some rooting hormone in a different container to prevent any contamination of the entire supply. Any substance that is still present after treatment ought to be thrown away rather than put back in its original container. When using a powder formulation, be sure to tap the cuttings to eliminate extra hormone.
To ensure adequate aeration, the rooting medium must be sterile, low in fertility, and well-drained. Additionally, it need to retain adequate moisture to prevent excessive watering requirements. Commonly utilized materials include coarse sand, peat and sand, or a mixture of one part peat and one part perlite (by volume) (by volume). Vermiculite should not be used on its own since it tends to compress and retain too much moisture. While being utilized, media should be hydrated.
Insert the cuttings into the medium between one-third and one-half of their length. Keep the stem’s vertical orientation (do not insert the cuttings upside down). Ensure that the buds are pointing upward. Just enough space should be left between cuttings for all of the leaves to receive sunlight. If the containers or frames are 3 inches or deeper, water them once more after inserting the cuttings. Place the cuttings in indirect light and cover with plastic. Stay out of the sun. To ensure that the cuttings take root, keep the medium wet. Regular misting of the cuttings will help them root better.
The type of cutting, the species being rooted, and the environmental factors all affect how long it takes to establish roots. Broadleaf plants need less time than conifers. Conifers can be rooted well in the late autumn or early winter. They can stay in the rooting structure until spring if they have rooted.
Cuttings that have just taken root shouldn’t be placed outside right away. Transplant them into a bed or into pots as an alternative. Before relocating them permanently, growing them to a larger size will improve their chances of surviving.

Is it ok to spread throughout the winter?
Many plants can be multiplied over the winter. Since the nursery is more peaceful in the winter, we frequently take cuttings then. Most people may believe that it’s too cold to take cuttings during the winter, however there are many plant species for which winter is the ideal time to propagate.
We always use a perlite and peat moss mixture when harvesting plant cuttings. Many of the wintertime cuttings might be directly planted in soil or a mixture of soil and sand. We specialize in plant propagation, thus we can confidently state that cuttings inserted into perlite and peat moss will yield better results.
You might as well use what the experts use since perlite and peat moss are so cheap. We combine 1 component peat moss with 9 parts perlite. We prefer to place the mixture onto a seedling tray, but you could also use a pot or any other well-draining container.
The most typical winter cuttings are made from deciduous trees and shrubs. Food crops that fall under this category include blackberries (we prefer the thornless variety), mulberries, blueberries, kiwi fruit, nectarines, peaches, apricots, and a plethora of other varieties.
Then there are well-known deciduous decorative trees and shrubs like maples, roses, hydrangeas, and wisteria. But there are numerous evergreens that can be successfully grown as winter cuttings in addition to deciduous trees and shrubs.
We frequently cut Buxus (box plant), Bay trees, Climbing jasmine, Portugal laurel, and Camellias during the winter. Fast-growing perennial flowers that can be cultivated in the winter include seaside daisies, Bradyscome, Scaevola, violets, and many others.
Protection
Providing protection from the elements will improve the performance of all cuttings. Cuttings are quite susceptible to drying out during the roots process. The cuttings are still fragile even though it is winter.
Even in chilly winter winds, cuttings can be dried very fast by wind. Your cuttings will become dried out by frosts. A little stem, such as a cutting, may shrivel up and die when a frost draws out the moisture from the stem and causes it to freeze.
Some people like to use plastic wrap to protect their cuttings. I believe that doing this on a small scale, such in a pot or even seedling trays, leaves the region too sensitive to extreme temperature swings. There isn’t enough airflow in the small space, which might breed fungus and sickness.
A more open, protected location with good ventilation is what I greatly like. That’s our poly tunnel, however I’ve also used the porch and the windowsill in the kitchen. Cold frames are yet another excellent choice. You’re OK to go as long as the location is sufficiently lit, frost-free, well ventilated, and gives wind protection.
Bottom heat
To encourage rapid root growth, many seasoned gardeners may provide bottom heat to their cuttings. Heat mat utilization is now quite economical for the backyard gardener.
By using bottom heat, we can mimic the warming of the soil that occurs in spring. The plants can be made to believe spring has arrived and it is time to begin growing by applying heat to the bottom of the cutting.
Some plants, like blueberries, actually require that bottom heat in order to make healthy cuttings.
Water
How frequently people should water their cuttings is a common question. There isn’t truly a universal solution. I believe that watering cuttings in the winter is more difficult than watering them in the summer.
The cuttings can essentially be watered every day without any problems throughout the summer. It’s far more difficult to gauge winter. Since the weather is obviously considerably colder, cuttings typically obtained in the winter will establish roots much more slowly.
Overwatering is a danger as a result. Cuttings that are overwatered will start to decay or grow fungus. Maintaining moist (not wet!) perlite, peat moss, or other media is key. Additionally, I advise against misting the cuttings.
Summertime is a good season to mist the cuttings because the water will quickly evaporate and won’t sit on the cutting for very long. Since the water doesn’t evaporate in the winter, fungus outbreaks are once more possible.
Another irrigation advice is to water only on bright, sunny mornings. Once more, this is to prevent the cuttings from being kept damp for too long. They might not dry until the following day if you water them in the afternoon or on cloudy days. It’s been way too long.
Keep in mind to just moisten the mixture the cuttings are placed in, not the cuttings themselves. This will considerably increase the likelihood of success and prevent any illness, rot, or fungus.
Time frame
Winter means that it takes much longer for the cuttings to strike. On a cutting taken during the winter, roots will typically take 2-4 months to form. Temperatures and lighting are to blame for this.
Most plants are able to determine the season based on the light. Most plants will start to produce new growth as the days get longer; at this point, our winter cuttings will also start to move.
With this knowledge, it may be tempting to put off taking cuttings until the end of the winter. However, in my experience, it is preferable to allow the buds to form in the propagation mix rather than on the tree or shrub.
My argument is that because the cutting is aware of its situation, it must first produce roots before it can develop. An early-spring cutting that was once linked to the shrub or tree and had a deep root system is now free of roots because the temperature has warmed up. I worry that this might cause too much shock and a far less successful cutting.
Keep in mind that providing bottom heat might also assist in convincing the cuttings that spring has arrived. Growing lights are another tactic some propagators employ; we don’t personally utilize them. Our winters aren’t too long because our climate is mild enough.
