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
How should I trim my cactus?
Cutting back a cactus is explained as a horrible joke. The straightforward response is: carefully. The majority of cacti feature a spine or prickle, which can be uncomfortable to come into contact with. For the larger garden specimens, wear long sleeves and pants and thick gloves.
Depending on the size of the plant, a variety of tools may be used, but pruners are the most common. Only the biggest ones will need a saw. As with all pruning, ensure sure the implement is clean and sharp to prevent damage to the plant and the spread of disease.
At the branch point, cut off the limbs, being cautious not to cut into the main stem. You can either use pruners to cut the pads or leaves off by hand.
Use a saw to cut away the main trunk at the desired branching point or plant height when working on a large task, such as pruning a columnar specimen. Make an effort to cut the stem where it is growing.
Old leaves must be removed from plants like agave in order to maintain their aesthetic appeal. Use shears to remove them from the plant’s base.
How can a cactus be chopped and preserved?
- First, trim the cactus. Use a sharp knife to remove the cactus’ top portion.
- Step 2: Let the cactus dry.
- Change the soil in Step 3.
- Replant the cactus in step four.
- Water the cactus in step five.
- First, remove the rotten portion.
- Step 2: Get rid of the rotten piece.
- Replant the cactus in step three.
Can you sever a cactus branch?
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.
Can I grow a damaged cactus again?
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.
Can a shattered cactus grow back?
Once established, cacti are hardy, tolerant plants that require little maintenance. They are particularly drought tolerant because they store water in their stems. If the cactus stem or roots are damaged, the wet, nutrient-rich inner tissues are exposed to disease fungus and bacteria, making the plant prone to plant infections. The best defence against harm to your cactus is vigilance. With the right care, broken plant stems and damaged roots can frequently be repaired or revived.
When ought I should prune my cactus?
Clearly, the answer is “yes. As was already said, you must occasionally prune your cactus plant to control its size and prevent crowding. In rare cases, pruning might prevent your plant from dying (in case of top-bottom rotting and pest infestation).
Keep in mind, too, that most cacti species don’t actually require any kind of shape or trimming until they have grown a big branch that threatens to topple your plant. The only time most gardeners are required to prune their cacti plants is when they need to take cuttings to replant.
If done correctly, cactus pruning can improve the plant’s overall appearance and minimise overcrowding, which raises the risk of disease and pest infestation. Mildew and sick plants can also develop from overcrowding.
Organ pipe cacti and totem pole cacti are examples of columnar cacti that can become spindly or tall and need to be regularly pruned to encourage thicker stems or lateral branching.
Flat pads on the opuntia act as the leaves. In this situation, you can take out a few pads and place new seeds in them. This still counts as a sort of trimming back or pruning.
When in bloom, the other cactus family members, like the Christmas cactus, generate flower stalks. When dead, these flower stalks get unattractive, and the only method to get rid of them is to cut your plant.
The most important benefit of trimming, despite its variety of uses, is that you can always use the bits you remove to propagate new plants.
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.
What does a cactus that is dying look like?
Possible dead cactus symptoms include: Cacti topple over or are exceedingly flimsy in the ground. Spikes could come off. These two symptoms point to both root rot and overwatering. Yellow turns brown in colour.
Can you save a dying cactus?
While skin-deep disorders in the upper body of the cactus can be easily handled, those that have spread to the roots typically result in a plant that is slowly dying. Excision of the diseased tissue works successfully for the majority of cacti. Dig out the damaged flesh with a clean, sharp knife, then let the hole dry out. When the wound is healing, avoid overhead watering.
There is not much you can do if the roots have been affected by the harm. You could attempt to repot the plant by removing the unhealthy soil and adding sterile soil in its place. Before replotting the roots in a new potting medium, thoroughly wash the roots out.
Taking cuttings and allowing them to grow roots for a brand-new plant is another way to salvage a mushy, soft cactus. Before inserting the cutting into the sand, let it a few days to callus over. The cutting may need to be rooted for several weeks. A healthy cactus that looks exactly like the parent plant will be created using this method of propagation.
Initial assessment
Understanding that a broken cactus’ stem or joint cannot be put back in place is the first step in dealing with the situation. The majority of the time, there will be a crack around the break, preventing it from being effectively re-joined. If your cactus has two symmetrical halves, you should leave it alone rather than risk causing it more harm.
Cleaning the pieces
Use a soft brush to remove any undesirable dirt and debris from the region near the break. Clean the area surrounding the wound and inside it well using a solution of warm water and mild detergent. In order to prevent infection and rot, it is crucial to get rid of any dirt and bacteria residues. Use a pair of sterile scissors or tweezers to carefully remove any dead tissues that are obstructing the wound’s ability to heal.
Minimize scarring
Avoid touching or applying pressure to a stem’s underside if it is spiky, as it is in many species, as this will only make the harm worse. Instead, apply green leaf gel to the region to help the healing process and reduce scarring.
Take care of the cambium
Always make sure the cambium is aligned before reattaching. The green living tissue layer immediately beneath the bark is called the cambium. It will be beneficial to use a piece of stem from a healthy plant to replace the broken one because cacti typically develop new stems from the cambium. Wood glue should be applied around the wound and the replacement should be securely held until it dries.
Avoiding infections
After a damaged cactus is successfully fixed, the biggest worry is keeping it from being infected because the new stem lacks any built-in defences against pathogens. Due to the fact that they draw dust, mites, and other pests that could harm your plants, keep your prickly companion away from windows and draughts. Dehumidifiers should also be kept close to cacti that are growing or blooming because this makes them more vulnerable to decay and fungal illnesses.
Dealing with the remaining half
Your injured cactus may occasionally be split in two with the top portion missing. Even if a wounded cactus only has one-half of its stem left, it can still be saved. New stems will gradually emerge from the plant, and once they are big enough, you can cut them off. Be patient; this process could go on for years. Your cacti may live a long time and become as thorny as you like with proper maintenance.
Consider grafting
Another method for fixing a broken cactus is grafting. This entails applying fragments of roots or stems from other plants to the injured area. After a year of neglect, you might think about repotting your cactus into a bigger container to allow the graft to develop freely. Once healed, your spiky pet won’t ever look ugly again. The best thing is that, in addition to teaching you what to do if the cactus breaks, you may repeat this process as much as you wish without harming the plant.
Re-planting as an option
You can think about propagating the broken piece as a new plant if it cannot be repaired. Remove any unnecessary pieces by taking the removed piece. Keep the stem out of direct sunlight and put it in a glass of water.
Plant your cactus cutting into the soil-based potting mix whenever new leaves start to emerge, then move it to a bright area of light. While you wait for new roots to emerge, water well and keep an eye out for growth. You can enjoy your newest family member by placing them in direct sunshine once the new stems have grown strong enough. Just keep an eye on it to prevent rot or infection, which would worsen the condition of your other indoor plants.
