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
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.
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 do you begin raising cacti?
To thrive, cacti need a sunny location in a compost that is very well-drained, like cactus compost.
Select a windowsill facing south or east for the greatest effects. If the windowsill gets too chilly in the winter, you might need to find them another position.
How to plant cacti
Plant cactus carefully at all times. Your skin may sting and bleed from the spines. To avoid harming yourself while planting your cactus, it is a good idea to use everyday kitchen tools like a fork, spoon, and thick tea towel.
Cactus should be planted in a compost that drains very well, such as cactus compost. Alternately, use a multipurpose compost devoid of peat that has been enriched with horticultural grit or vermiculite to improve drainage.
To finish the aesthetic of the pot display, add a layer of horticultural grit or pebbles. Additionally, this stops water from re-splashing on the cactus.
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 how to make a decorative mulch, which compost to use, and why salad tongs are the best tool for handling cacti:
Caring for cactus plants
Water cacti in the summer only once a week at most. A decent watering less frequently is preferable to a little-and-often strategy. In the coldest months, you shouldn’t need to water cacti at all.
Cacti should be repotted every two years to receive fresh compost; larger pots aren’t always necessary.
Stan Griffin of Craig House Cacti shares his three best growing advice for cactus plants in this Golden Rules video, including when to water, feed, and when not to. He also offers guidance on how to take cactus cuttings.
Growing cactus plants: problem solving
Cactus plants often pose no problems. Overwatering or inadequate lighting might cause them to decay at the base. The plants frequently die as a result of this.
Spindly growth is possible in cactus plants, although it is simple to fix. In our Quick Tips video, Emma Crawforth from BBC Gardeners’ World Magazine explains everything.
Cactus varieties to grow
- Golden barrel cactus, Echinocactus grusonii, is initially globular but later becomes tall. It has brilliant green stems with spiky ribs that are native to Mexico. In the summer, flowers that are bright yellow bloom.
- The varied cactus Gymnocalycium paraguayense has flattened spines. In spring and summer, it blooms a creamy white color.
- A globe-shaped cactus with brilliant pink, funnel-shaped blossoms is called Mammillaria spinosissima. It has reddish-brown or yellow center spines.
- Rebutia krainziana is a clump-forming barrel cactus that grows little, white areoles and spines in contrast to its dark green, up to 7 cm in diameter stems. Large, yellow or red flowers grow in a dense clump around the main stem in late spring.
You Will Need
- Cacique seed
- clay and plastic miniature pots
- Cactus compost or free-draining compost
- fine grit or vermiculite
- glass sheet
- spoon or fork
- Tweezers
- Gravel
Step 1
A pot should be filled with a loose-draining, moist compost. Firm the surface down gently and level it. Spread your mixture of cactus seeds evenly around the area, being careful not to sow them too densely.
Step 2
Over the seeds, evenly cover the surface of the compost with a thin layer of vermiculite or fine grit. To keep the soil moist, leave the pot wrapped in a clear plastic bag in a greenhouse or on a warm windowsill.
Step 4
Your seedlings should be ready for transplantation the following spring. To gently pry out individual cactus, use a fork or spoon, being careful not to get the spines on your skin.
Step 6
Add compost all around the seedling and give it plenty of water. If more compost is required, add it after placing the gravel around the seedling with the spoon. Keep in a bright area, like a windowsill, and turn on the pot as necessary.
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.
Can you replace a cactus that has been broken?
As long as the damaged component is otherwise healthy, a broken cactus arm or stem segment can be used to grow a new cactus. If your cactus has spikes, never forget to wear protective gloves. Until the ends of the plant piece harden and start to callus, allow it to sit in a cool, shaded area for about a week.
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.
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.
Can succulents establish roots in liquids?
In water, most succulents can be multiplied. If you have a succulent that is stretched out, you can take stem cuttings and root those, or you can create roots from healthy single leaves.
The most successful succulents are those with thick, meaty leaves, like the Echeveria plant. So when you first try your hand at succulent propagation, these are an excellent option.
It makes sense to multiply a few leaves at once. By doing this, you increase the likelihood that there will be survivors. While others may decay or just wilt and wither away, certain succulent leaves will only produce roots and no new plant.
How do you grow small cactus indoors?
As long as they are placed in an area that receives at least 4 to 6 hours of sunshine every day, cacti can be cultivated indoors. To ensure they are etiolated, we advise rotating them daily in your brightest windowsill, which is typically a southeast-facing window.
