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 you plant a portion of cactus that has been chopped off?
A loved cactus plant might quickly lose a portion due to overly active kids, scavenging animals, an accidental bump, or an unplanned incident. You need not worry if it occurs to you because you are not required to discard the chopped piece.
Even if the main plant can still survive if a portion of its stem is lost, it may seem wasteful to toss the broken piece and ignore the rest.
Can you then cut a chunk off of a cactus and plant it? Yes is the clear-cut response. Cuttings can be used to grow a sizable number of cacti species. Hedgehog, prickly pear, and branching columnar cacti like the night-blooming cereus are a few of the common cactus species that are typically reproduced via cuttings.
Don’t discard the broken piece if your cactus accidently breaks off a portion of it. Instead, replant it from seed and let it grow.
Before planting, how long should cactus cuttings have dried?
Care instructions for cacti vary widely depending on the particular circumstances in your garden. The recommendations for caring for cactus in a cool, damp setting are very different from those for a hot, dry environment like Phoenix. Generally speaking, cacti and succulents prefer dry soil, warmth, and light. Cacti are fairly tolerant of unfavorable conditions, but better ones lead to better outcomes.
Planting Bare Root Cacti
Open boxes as soon as you can after obtaining your bare root cacti plants. Trim any visible damaged roots with fresh scissors before planting. Till new roots begin to grow, keep the young cactus plants a little bit dry. If it’s hot outside, it might take a few days or weeks, but if it’s dormant, it might take longer. Some cactus plants may become de-acclimated from their usual full sun environment during shipment, and they risk burning if they are exposed to the sun too quickly.
Planting (unrooted) Cuttings
Before planting your cactus cuttings, let them dry for 10 to 45 days after you receive them. (Longer drying times are needed when there are thick cuts and cool temperatures.) Leave the cut in a warm, shaded location as opposed to direct sunlight to help the wounds heal. After that, place it in DRY cactus potting soil and wait 10 to 45 days before watering it again. Starting a gentle, regular watering cycle is safe once the cutting forms a root system. Always wait until the soil is completely dry before watering it again. A cutting will be much more likely to die from overwatering than from underwatering.
Watering
Giving specific instructions on how to water cacti and succulents is challenging. During the winter months, when cacti go into hibernation, they shouldn’t be watered. Keep cactus dry during the winter, especially if they are maintained in an area with a relatively low temperature. When they are active, cacti need to be hydrated.
If the plants are protected from rain, a typical watering schedule can be as follows: once in January, once in February, twice in March, and 2 to 4 times monthly during the growing season, depending on the circumstances.
The dirt in the pot should be given enough water to completely saturate it. Water that is too much should drain easily. The occasional rain shower won’t hurt you in the summer. Rain is preferable to tap water for plants. On the other hand, cacti should be planted in a protected spot during a prolonged rainstorm.
Although technically free of chlorine and alkaline salts, regular tap water will do. The cacti will develop white stains from hard water and chlorine, which is ugly and does close the stomata. (pores)
Nutrients
During their growing season, cacti and succulents require constant feeding (Spring-Summer). They require an appropriate variety of minerals. Potassium (K) promotes fruit and flowers, phosphorus (P) promotes healthy root development, and nitrogen (N) promotes vigorous top growth. Other trace elements are also required by cacti. The ideal ratio of nutrients is 20 percent nitrogen, 20 percent potassium, 20 percent phosphorus, and all of the other trace elements. However, any commercial houseplant fertilizer will do.
Light
The minimum temperature for mature cacti and succulents in a warm region is 61 degrees Fahrenheit (16C). The photosynthetic process typically requires direct or filtered sunlight in cacti. An artificial light source, such as fluorescent lighting, can be used in addition to natural light.
Soil Mixture
Cacti have evolved to live in nutrient-poor, rocky, sandy, or clay-based soils. The perfect soil or potting combination, however, will drain quickly and still hold some moisture. To guarantee proper drainage, always use a grittier mixture; pumice works excellent. An acidic soil is preferred by the majority of cacti.
Pots and Containers
Cacti and succulents don’t require a lot of soil depth. Check to see if every container has drainage holes. Before adding soil, line the bottoms with anything like gravel or broken pieces of pottery. Choose plants with comparable cultural requirements and growing seasons when growing them all together in a container. Many succulents that grow slowly flourish when combined with desert cacti.
Pest and Diseases:
Although cacti are pest and disease resistant, they are nonetheless susceptible to scale, mealy bugs, and several fungal and viral infections. There are many treatments for scale and mealy bugs, but I’ve found that malathion and orthene combined with a wetting agent work really well. The best defense against viral and fungi infections is prevention. That is creating favorable conditions for growth, and watch out for too much wetness. Fortunately, desert plants can tolerate a wide range of unfavorable environments. The cactus will take care of the rest if you just give it the right range of conditions. Enjoy your garden!
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.

When is the best time to collect cactus cuttings?
Cacti have benefited from this summer’s favorable weather by responding with new growth. In just a few weeks, my bunny ears cactus, Opuntia microdasys, produced three new pads. That is, until I made the decision to clean the window behind it, at which point all three of the new pads were stuck to the cleaning cloth with one slightly clumsy motion.
Not a big deal, though, as cacti are remarkably simple to spread. The optimal time to take cuttings is during the summer, but I’ve had success taking them as late as now, and emergency cuttings are the best way to save the plant if life provides you unexpected bunny ears to propagate or the bottom of your cactus starts to rot.
You only need to remove one segment from a prickly pear, a rabbit ear, or any other segmented cactus to produce a new plant. These are some of the simplest to reproduce; just gently cut off a part while using thick gloves or kitchen tongs (never assume any cactus spine will be nice, no matter how small). You can cut off or divide each head of a mound-forming cactus, such as a mammillaria or an echinopsis, at the soil level. Use a sharp knife to make a straight, precise cut. Take a good chunk of the head off a columnar cactus if possible. The similar method can be used to salvage the healthy portion of rotting bases while discarding the remainder.
Lay the cutting carefully on its side on a saucer. Before it can root, the exposed flesh needs to callus over, and exposure to air causes this to happen. With a small specimen, this might take a day, but with a bigger surface area, it might take a week.
You can place a hard callus into a tiny pot once it has hardened. Cacti require extremely free-draining environments for their roots. I advise using a ratio of five parts grit and horticultural sand to one part compost when we enter the latent phase of growth. Running water through the mixture in the pot will allow you to check whether it drains rapidly.
Pads or segments can be positioned either upright or on the ground. Cacti that are upright in the pot should stay that way. Water as soon as you plant and again when the soil is entirely dry; throughout the winter, this may only require one watering until spring. Leave the plant in a well-lit area away from the sun.
Cuttings can be completed in 24 hours in the summer but up to three or four months in the winter. Either roots will show through the drainage holes, or the cutting will feel firm in the container, indicating that it is rooted. And fresh spines will grow in the spring.
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.
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 often should cactus 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.
