Cacti have benefited from this summer’s favorable weather by responding with fresh growth. In just a few weeks, my bunny ears cactus, Opuntia microdasys, produced three new pads. That is, until I made the decision to wipe the window behind it, at which point all three of the fresh pads were adhered to the cleaning cloth with one fairly awkward 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 significant 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.
When should I water my newly planted cactus?
Today, we’ll talk about another aspect of caring for cacti. In this article, we’ll discuss how to repot or transplant a tiny, tall, or huge cactus and share our insider knowledge and advice. We’ll also go over when to repot your cactus and how to do it safely so you don’t get stabbed or harmed. Then we’ll cover how to take care of cacti after repotting them.
Should I repot my cactus and how often should I do it?
Yes, you must repot new cacti every year and adult plants every two years. Because cacti grow and eventually require additional space and new growing material, repotting or transplanting them is crucial.
Growing cacti will require additional room because their roots will spread out inside the soil mixture. By inspecting the rootball at the pot’s base, you can make sure (which should have drainage holes). You should repot your cactus as soon as possible if any roots are showing.
The same holds true if you remove the cactus from its pot and can see its roots wrapping around the root ball. Repotting also typically “wakes up” your cactus and promotes healthy growth.
What is the best time to repot a cactus?
The conclusion of the dormant season is the ideal time to repot cacti. Your cactus will experience less stress as a result. For many plants, the dormant time will vary. However, the majority of cacti that are found in regions with harsh winters are compelled to hibernate from November until the end of February.
General important tips for repotting cacti:
- Before or after transplanting your cacti, avoid watering them. So that roots can continue to grow, let the soil dry. Additionally, you should hold off on watering your cactus for seven to ten days after repotting. This is crucial since handling the plant could harm the roots, and any contact with water could kill the plant.
- Since certain cacti have extremely pointed spines, additional protection is required when repotting them. This can be a spare glove, newspaper, or piece of cloth.
- When repotting cacti, you must safeguard your hands. Several cactus will have longer, sharper spines, so be extra cautious! These nitrile coated gloves, which function far better than leather gloves since they are thicker, are the ideal tools for defending your hands from spiky cacti. Wear two sets of gloves or get gloves with double coating if you have a cactus with sharp spikes.
How to repot your cactusstep by step overview
- Prepare the materials and the area before you start repotting your cactus. Have ready-mixed soil, a plastic container for handling root balls, a brush, nitrile gloves, a wooden stick, some folded newspaper, and shears with micro-tips or scissors on hand as well.
- Select a container for your cactus. A pot should be larger than the one before it and cleaned and sanitized. Avoid choosing a pot that is too big since cactus want a snug fit. When choosing a pot, make sure it isn’t too deep and that it is at least 1-2 inches wider than your cactus. However, there should be enough room for the roots of the cacti to sit comfortably in the pot. Pick the same-sized container and repot your cactus if it has extremely weak roots and hasn’t been growing steadily. This will encourage growth. Add bone meal, egg shells, or time-release fertilizer to the soil. Read more about selecting a container here.
- Add charcoal and some rocks or gravel to the pot you’ll be using. This will facilitate drainage and stop soil from escaping drainage holes. Add some fresh soil mixture on top before planting your cactus.
- Remove your cactus from the pot (we’ll go over how to do it in a moment) and clean the roots of any old soil. If the old soil is difficult to remove, soak it.
How long does a cactus cutting take to take root?
Even for novice gardeners, cactus species are among the simplest plants to root at home. The method is effective throughout the year, although cactus cuttings potted in late summer to early autumn develop the quickest roots and healthiest plants. Cactus cuttings can root easily, but they must be carefully prepared beforehand and potted in sterile rooting medium to prevent them from wilting and decomposing before they take root. Most cactus cuttings that have been potted usually take four to six weeks to root and are prepared for transfer one month afterwards.
What is the quickest method for cactus re-rooting?
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 long should cacti be allowed to dry out before planting?
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!
How are cacti grown from cuttings?
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.
After repotting, should I water my succulent?
1. To get started, fill your new planter 3/4 full with pre-mixed succulent or cactus soil, which is often available at any nearby nursery or home improvement store. You can combine standard potting soil and perlite in equal amounts to try making your own soil. Make sure the planter is at least 2″ wider than the diameter of the succulent if you are relocating it to a larger container. Your succulent will have plenty of room to expand and become stable as a result.
2. Remove the succulent from its present container and gently separate the roots. To loosen the roots and remove the soil, you can “tickle” them from the bottom. Consider this phase as a pleasant stretch for the roots. They can stabilize in a larger pot and acclimate to their new soil by being spread out and lengthened. This is the ideal time to remove any dead leaves and brush away any dead roots from the plant’s base. While doing this, be careful to brush away any old or extra dirt.
3. To support the plant, dig a small hole in the fresh dirt, lay the succulent in it, and then gently cover the roots with extra potting soil. Don’t cover any leaves or allow them lay on top of the soil; only add enough to cover the plant’s base. As a result of the leaves absorbing too much moisture from the soil, this will cause them to rot.
4. After the plant has stabilized, you can add colored rocks, pebbles, or sand to give your new succulent plant in a pot a unique touch. Make sure the material drains adequately if you do add something on top so that water can reach the soil underneath.
5. In this case, the situation dictates how to water. Depending on the type of plant and when it was last watered, a succulent that has been repotted may require different first watering. However, it is typically advised to hold off on watering your succulent for at least a week following repotting. Make sure the soil is dry before giving it a good soaking without drowning it.
6. Enjoy your succulent in a new pot! Depending on your environment, sunlight, etc., water your succulent once per week to three weeks to keep it healthy. Water should be applied when the soil is dry. Leave it alone until it dries if it is still wet. They are tough little plants, so try different things to see what works best for your new addition.
