If you want indoor plants that practically care for themselves, succulents and cactus plants are the ideal choice.
As detailed here, stem or leaf cuttings can be used to readily propagate the majority of cacti and succulents. Always remove entire segments from cacti with segmented stems (such as Christmas cacti and prickly pears), as cuttings don’t divide segments in half.
Aloes, haworthias, and agaves are clump-forming succulents that can be divided by simply removing the plant from its container and slicing the rootball. Numerous Mammillaria and Echinopsis cacti can be separated, or individual heads can be removed and used as cuttings.
In our No Fuss video guide, Kevin Smith of Gardeners’ World Magazine demonstrates how to use cactus plants to make a visually appealing display. Kevin discusses the benefits of using salad tongs to handle cacti, the best compost to use, and how to make attractive mulch.
Step 1
Select a healthy stem that is at least 10 cm long and use snips to cleanly cut it off. When handling spiky cacti, use tongs. Remove entire leaves from plants without stems by hand; don’t chop them off. Until the cut surfaces have healed over, leave cuttings on a window sill.
Step 3
After heavily watering, set the pot on a warm ledge that’s preferable out of the sun. Cuttings of succulents or cacti shouldn’t be put in propagators or covered with plastic bags.
Step 4
Watch the cutting and moisten the compost when it feels dry. The majority of cactus and succulent cuttings take a month or less to root, although new growth could take longer.
Can cactus be chopped and then regrown?
Probably the most frequent and straightforward method of propagation is stem cuttings. Stem cuttings are an effective method for multiplying many cacti. Stem cuttings from an existing plant are removed, then left to calluse and dry out. Eventually, the cuttings will begin to take root from the cut end and grow into a new plant.
Some cacti that are frequently multiplied via stem cuttings include:
- Prickly pears or opuntia
- Collapsed cactus
- Globular and pincushion cacti
Can a cactus cutting be rooted in water?
It’s time to get your cutting ready for planting in a pot once it has dried! Cactus propagation can potentially be done in water, just like with other houseplants, but it’s not a very usual procedure because they thrive in soil.
Your brand-new cutting will require excellent drainage to survive, much like other cacti (unless it’s a jungle cactus like the Christmas cactus). The roots of cacti have not developed to become used to extended wet periods. They enjoy a cool splash, but the soil shouldn’t be prone to being wet or humid afterward; instead, it should immediately dry out again.
It’s not too difficult to spot an excellent cactus soil because it will be grippy and contain little to no potting soil at all. You can either purchase a prepared cactus soil combination or create your own by mixing 1 part potting soil, 1 part perlite, and 1 part orchid bark (not too gritty) for your cutting.
As far as planters go, as long as they have proper drainage, you should be set to go. Standard plastic nursery containers are excellent, but some cactus growers like to use clay planters to provide even more drainage. Water can really evaporate through the walls of this substance since it is porous.

How long does a cactus cutting take to take root?
It’s time to pot up offsets from cacti after removing them and letting them callus. The ideal medium is grippy and well-draining. You can buy cactus mixes or make your own by mixing 50 percent peat or compost with 50 percent pumice or perlite.
Cuttings only require a pot that is slightly larger than their base diameter. In order to prevent the offset from toppling over, cover one-third to one-half of the base with the medium. Keep the medium mildly moist and place the pup in indirect but bright sunlight.
Although some cacti can take months to root, most do so in four to six weeks. By observing any fresh green growth, which shows that the roots have taken hold and the plantlet is receiving nutrients and water, you may determine when it has rooted.
How do you re-root a cactus fragment?
Large desert cactus, such as the prickly pear (Opuntia spp. ), can be rooted either indoors or outdoors in U.S. Department of Agriculture plant hardiness zones 3b through 11. Usually, smaller desert plants are rooted in flower pots. One-third to one-half of the pad or stem should be buried, bottom end down, in the potting media after making a small hole in it. Place in a warm environment with filtered light that is bright. Wait to water the plant until the roots start to form.
How frequently do cacti need to be watered?
The most frequent reason for cacti failure is improper watering, whether it is done too much or too little. Cacti have evolved to store water for extended periods of time and can maintain moisture through droughts because they are endemic to arid regions and dry temperatures. They have a limited capacity, which is why over-watering can result in a variety of issues.
When it comes to regularity, watering your cacti will largely depend on the season but also on the variety. Checking the soil is the easiest technique to determine whether your cactus needs water: It’s time for a drink if the top inch is dry. That entails applying the “soak and dry procedure” on cactus.
What is the soak and dry method?
The soak and dry technique is thoroughly wetting the soil until part of it begins to flow out the drainage hole, then waiting until the mixture is nearly dry before wetting it once more. If done properly, this strategy will help them endure a period of under-watering should you need to travel or leave the house because it takes use of their natural tendency to store water (or if you just get busy and watering falls to the wayside, as happens to all of us now and again).
Watering during the growing season versus the inactive season
Like with many houseplants, the season affects how frequently you need water. It becomes more crucial that you get in the habit of examining the soil to determine whether your cacti are thirsty. A healthy cactus needs watering every one to two weeks during the growing season, according to general wisdom. The frequency changes to once every three to four weeks during the off-season.
Even then, it’s crucial to examine the soil. The same way that not all interior spaces and not all cacti are alike. The only way to be certain that your cactus require watering is to carefully examine the soil to determine how dry it is because there are so many different factors.
Can cactus roots grow back?
Wild cacti with paddles and branches often drop them to the ground during the rainy season, where they take root. An example of vegetative self-propagation is this. Even a broken cactus will make an effort to establish roots in the areas of its body that come into touch with the soil. The paddle-like branches of the prickly pear cactus (Opuntia compressa), which thrives in USDA plant hardiness zones 4 through 9, are used to produce colonies. If extracted from a healthy cactus, it is possible to create a new cactus from an arm.
Can a cactus grow in water?
Fans of cacti and succulents are aware that properly watering these plants is difficult because it’s easy to over or underwater them. That’s no longer a concern thanks to your germination plate. To ensure that your cactus always receive the proper amount of moisture, you can convert them to hydroponic growth.
Can succulent cuttings be planted directly in the ground?
What is there to love other than a succulent? Obviously, a full garden of succulents! Fortunately for us, it’s simple to propagate a variety of these resilient, vibrant plants at home. We can’t wait to see succulents growing all year long in containers around the house and garden; there are various easy ways to reproduce them.
Propagating by Division: Plants that have gotten too leggy perform best with this method, which produces new succulents from cuttings. Start by delicately removing any leaves that may be attached to the stem below the rosette; be sure to preserve the leaf’s base while you do so. After all the leaves have been eliminated, cut the rosette with shears, leaving a brief stem intact. The cuttings should be let to dry in an empty tray for a few days until the raw ends have calloused. The cuttings can then be rooted in either water or soil.
Soil: After the stems have calloused, set the cuttings on top of a shallow tray filled with well-draining cactus/succulent soil. From the base of the cuttings, roots and little plants will start to emerge in a few weeks. Once the roots start to show, water sparingly once a week; take care not to overwater. The parent leaf will eventually wither; carefully remove it while taking care not to harm the young roots. Your propagated succulents can be replanted once they have established roots. As soon as the plants are established, keep them out of direct sunlight.
Water: After the stem has calloused, place a cutting with the end barely visible above the water’s surface on the lip of a glass or jar filled with water. Pick a sunny location for your glass. The incision will eventually produce roots that extend toward the water. Once roots have sprouted, your new succulent can either be replanted in succulent potting soil or allowed to remain submerged in water as illustrated above.
Offsets are little plants that develop at the base of the main specimen, and many species of succulents, such as aloe, hens and chicks, and some cacti, will generate them. Check for root growth after an offset has developed for two to three weeks before carefully twisting, cutting, or using a sharp knife to separate it from the main stem. Be cautious to prevent destroying any already-formed roots. Follow the directions above for propagating in soil or water, letting the offsets dry, establish roots, and then repot when they have had time to callus any exposed regions. Removing offsets has the added benefit of enhancing the health of your current succulents and redirecting energy into the growth of the primary plant.
Which cactus parts can be multiplied?
The majority of cacti are simple to grow from stem cuttings, particularly those with segmented stems like blue candles, prickly pears, and Christmas cacti.
How can I tell whether my cuttings have taken root?
When cuttings are kept warm, at a temperature of about 70 degrees Fahrenheit, roots develop on them the fastest. By setting the container of cuttings on a heat mat made for roots, which is readily available at most nurseries or garden centers, you can maintain this temperature. Anti-desiccant spray, which helps stop water loss from stems and leaves, can be sprayed over the section of the cuttings that reaches above the medium to speed up roots. In a ready-to-use form, anti-desiccant sprays are sold in garden supply stores. When the top seems dry to the touch, moisten the medium and keep the cuttings in bright, indirect light. When you gently tug on a stem and feel a little resistance, or when you notice fresh growth, the cutting has rooted.
Removing cactus pups from the parent plant
You must first learn how to separate the offsets from the parent plant. A 10 percent bleach solution or some alcohol should be used to clean a sharp kitchen knife. By doing this, you may sterilize it and stop diseases from getting into your cactus through the cut places.
Find a decent pup, then carefully cut it off at a 45-degree angle. To prevent the cut area from rotting before it forms a callus, make sure the cut is angled to deflect water. Some gardeners enjoy sprinkling sulfur powder on the pup’s cut end to stave off decay and fungus.
However, if you let the cut end fully callus before roots, sulfur powder might not be required. Depending on the circumstances in your home, this can take a few weeks or a month. The cut end of the offset will be dry, stiffened, slightly shriveled, and yellowish when it is prepared for rooting.
To view the junction between the parent plant and the offset when getting the offset, make sure the top of the pup is free of soil. You might find that disconnecting the pup manually is considerably simpler if the joint is clear.
Make sure to clip off any parent plant material that may be present on the offset. If not, it will begin to deteriorate, which could have a negative impact on your pooch.
Rooting the pup
The next step is to root the puppy after you’ve acquired it. Only if your dog lacks roots is this procedure required. Consider putting your puppy in dry soil with some gravel for a few days or up to a week to help it root. When it starts to develop a few roots, watch it carefully and remove it right away.
The offset can also be planted in a small pot with perlite, charcoal powder, and sand to help it establish roots. All puppies with short roots should skip this phase.
Growing the offset
It’s time to pot your pups once they have a few roots established. Prepare the container and potting mixture for your offsets first. Make sure the container is the appropriate size and has lots of drainage holes. A pot that is just slightly bigger than the diameter of the cactus puppies’ base is required.
Additionally, the soil should be grippy and have sufficient drainage. You can either buy commercial soil or manufacture your own by mixing peat, pumice, and perlite in equal parts.
Place your dog in the soil with caution, but avoid pushing too deeply. The pup’s stem should only be partially buried. Make sure your dog is sturdy enough to prevent falls. Keep the soil moist and place the pot in an area that receives bright but indirect sunshine.
However, wait a few days before watering your offsets after planting. Before watering, wait at least five days or a week. By doing this, the likelihood of root rot and fungus diseases is reduced.
It’s also important to keep in mind that some cacti have a propensity to develop tiny pups beneath their stems. Because they receive less sunlight, these offsets are frequently too tiny.
Such puppies should be separated from the parent plant and allowed to dry out for a few days before planting. After planting, keep them there for a few days before transferring them gradually to a sunny area.
