How Do You Plant a Cactus Cutting for Successful Growth?
How Do You Plant a Cactus Cutting?
To plant a cactus cutting, gather gloves, perlite, peat or premium peat-based potting mix, a plant pot with good drainage holes, and optional rooting hormone powder.
If using the powder, dip the cut end of the cutting into it and let it dry.
Create a cactus rooting mix by combining 3 parts perlite with 1 part peat or potting mix, then fill the pot with the mix, leaving space for the cutting in the center.
Gently place the cutting in the pot, resting it on a layer of perlite, and add another thin layer on top.
Put the pot in a well-ventilated location with adequate light, avoiding intense and prolonged direct sunlight.
Allow the cutting to root for about 3-4 weeks, checking for root development after 2 weeks.
Once roots form, the cactus can be watered.
Alternatively, cuttings can be rooted directly in the ground, protecting them from excessive sunlight and moisture.

Did You Know?
1. Cactus cuttings have the unique ability to sprout roots and grow without the presence of soil. In fact, you can successfully plant a cactus cutting by simply placing it on a dry surface and allowing it to root on its own.
2. Contrary to popular belief, not all cactus species require high levels of sunlight. Some types of cacti, such as the epiphytic varieties, actually prefer shade and can thrive in shady areas like forests.
3. When handling cactus cuttings, it is essential to let the wound dry out before planting. Allowing the cut end of a cactus cutting to dry for a week or two before planting it helps prevent rot and increases the chances of successful rooting.
4. Cacti rely on a unique photosynthetic process called Crassulacean acid metabolism (CAM) to survive in arid environments. Unlike most plants, cacti close their stomata (tiny pores on leaves) during the day to reduce water loss, and open them at night to absorb carbon dioxide.
5. Some cactus species can live for hundreds of years. The oldest known cactus is a candelabra-like species called Saguaro (Carnegiea gigantea), which can live for over 200 years and reach heights of 40 to 60 feet. These iconic cacti are native to the Sonoran Desert in Arizona, as well as parts of Mexico.
Gathering The Necessary Materials
When planting a cactus cutting, it is crucial to gather all the necessary materials beforehand to ensure a successful and smooth process. These materials include:
- Gloves: These will protect your hands from potential injuries caused by the cactus spines.
- Perlite: This will help create the ideal rooting environment for the cutting.
- Peat or premium peat-based potting mix: This will also contribute to the favorable rooting conditions.
- Plant pot with good drainage holes: It is important to have a pot with sufficient drainage holes to prevent waterlogging.
- Optional rooting hormone powder: Consider using a rooting hormone powder, such as Rootex-P, to encourage faster root development.
Remember to always prioritize safety by wearing the gloves when handling the cactus.
Choosing The Right Pot Size
The size of the pot is crucial for the successful growth of a cactus cutting. When selecting a pot, consider the size of the cutting and choose a size that allows for adequate space for root development.
- For small cuttings, a pot with dimensions of at least 25cm in height and 20cm in width is recommended.
- For larger cuttings, pots that are at least 40cm in height and 30cm in width are required.
Providing enough space in the pot will enable the cactus cutting to establish a healthy root system and promote overall growth.
Using Rooting Hormone (Optional)
Using rooting hormone powder is not mandatory when rooting a cactus cutting, but it can significantly enhance the success rate. Before planting the cutting, you can choose to dip the freshly cut end into the rooting hormone powder. This powder contains special compounds that stimulate root growth. Once dipped, it is important to allow the cutting to dry in a well-ventilated area. While not required for all cactus cuttings, rooting hormone powder can be particularly beneficial for cuttings that are more likely to face difficulties in establishing roots.
Creating The Cactus Rooting Mix
To create an optimal environment for root development, it is crucial to prepare a suitable cactus rooting mix. This mix can be made by combining three parts perlite with one part peat or potting mix. Perlite is a lightweight and porous material that promotes proper drainage and aeration, while peat or potting mix provides essential nutrients and moisture retention. The combination of these two components creates the ideal balance for the cutting to establish roots and thrive. Ensure that the rooting mix is well-mixed before proceeding to the next step.
Placing And Caring For The Cactus Cutting
Now that you have gathered the necessary materials and prepared the rooting mix, it’s time to plant and care for the cactus cutting.
- Start by filling the pot with the cactus rooting mix, leaving enough space in the center for the cutting.
- Gently place the cutting into the pot, resting it on the layer of perlite.
- Add a thin layer of perlite on top of the rooting mix to provide further support and moisture regulation.
After planting, find a suitable location for the potted cactus cutting.
- It is essential to choose a well-ventilated area with abundant light.
- Keep in mind that while cacti require sunlight for growth, intense and prolonged direct sunlight should be avoided.
- Suitable locations include windowsills with indirect sun, undercover outdoor areas, well-ventilated shade or greenhouses, and well-lit rooms.
- On the other hand, unsuitable locations include north-facing windows with direct sun, dark rooms, direct sunlight in the yard, pools, and swampy caves.
Allow the cactus cutting to root for approximately 3-4 weeks.
- Patience is key during this stage, as frequent checks may damage the delicate roots.
- After about 2 weeks, you can carefully check the base of the cutting for any signs of root development.
- Once small roots have formed, the cactus can be watered.
Alternatively, cactus cuttings can be rooted directly in the ground.
- When using this method, take caution to protect the cuttings from excessive sunlight and moisture.
- In such cases, gravel can be used as a planting medium to ensure proper drainage, and stakes may be necessary for stability, especially when dealing with large cuttings.
By following these instructions and adequately providing for your cactus cutting’s needs, you can ensure successful growth and enjoy the beauty of a flourishing cactus plant.

Frequently Asked Questions
Can you grow a cactus from a cutting?
Yes, it is possible to grow a cactus from a cutting. By cutting off the tip of the cactus, removing some of the bottom leaves, and using rooting hormone, you can place the cutting in perlite or potting mix. It is essential to wear thick gloves when taking cuttings from cacti to protect yourself from the prickly spines. Stem cuttings can also be used for a more substantial and vigorous start by cutting a larger stem. With the right care and conditions, the cactus cutting can establish roots and grow into a new plant.
How do you plant cactus step by step?
To plant a cactus step by step, start by preparing lightweight, well-draining soil. Dig a hole that is deep enough to accommodate the root ball or stem of the cactus, making it 1½ times as wide. Ensure that the north side of the plant is facing north before setting it in the hole. Finally, carefully backfill the hole with soil, gently tamping it down to provide stability for the cactus. Water the plant sparingly, allowing the soil to dry out between waterings, as most cacti prefer dry conditions.
How deep do you bury a cactus cutting?
To successfully root a cactus cutting, it is advised to bury it approximately an inch under the soil or deep enough to ensure it remains steady and upright on its own. It is crucial to refrain from watering the cutting until its roots have begun to develop. By following this planting method, the cutting should establish roots and commence growth by the arrival of spring.
Can you put cactus cuttings straight into soil?
Absolutely! It is entirely possible to plant cactus cuttings directly into the soil. However, it is crucial to consider the amount of sunlight they receive during this phase, as excessive exposure can lead to sunburn. Therefore, it is advisable to select a suitable spot for them, offering some shade or utilizing a shade cloth until the cuttings have acclimated and grown stronger. Once established, these resilient plants can thrive and grow magnificently in your garden beds or outside areas.
