The ubiquitous indoor plant known as the pencil cactus, Euphorbiatirucalli, is a quick-growing member of the Euphorbiaceae family. Mature plants frequently resemble pine trees and can reach heights of up to 25 feet. They can be easily pruned, and doing so shouldn’t damage the plant. Here are some trimming pointers.
Avoid coming in contact with the sap’s white, latex-like surface if you can. This sap can occasionally cause significant skin and eye irritation. When it dries, it will turn black and stain your clothing as well. Additionally, these plants are not suitable for composting due to their sap.
Remove any branches that are infected, damaged, or dead. This will make the plant look cleaner and encourage new development.
Establish the desired height and shape for your plant. Then, by removing the branches above a node, shape the plant as desired using pruners or heavy, sharp scissors. Cut each branch at the base, where it originated, while pruning. Do not allow the stem to have a protruding stub.
You can further thin the plant if you’d like by removing any vertical branches that are overly numerous, weak, or thin. Once more, remove these branches at the source. Additionally, increasing air circulation around and within the plant by thinning enhances its general health.
Throw away the plant bits you removed with care. Alternately, gift them to friends who might be interested in having one of their own. Just make sure they wait a few days for the wound to heal and form a callus before putting the bottom few inches of the cuttings in the ground.
The optimal time to prune is in the spring when the plant has begun its active growing season and light and temperature levels have increased. Avoid removing too many branches all at once to avoid shocking the plant. In general, pruning should only remove around a third of the plant at a time. Also keep in mind that once something is cut off, it cannot be reattached. So you might only do a light pruning before determining whether it fulfills your needs. If not, continue pruning until the desired outcome is achieved.
Can a pencil cactus be pruned?
- Trim three more bigger branches. The first was tethered to the little clothesline, the second was entirely bent over, and the third was the other top branch.
- Step back and take a look at it.
- To get some of the smaller branches off the wall, prune them toward the back.
- Success
- the plant is now self-supporting and appears better!
The Cuttings
Before planting, I always let my Pencil Cactus cuttings heal off (dry over at the ends, like we do with a wound).
Succulent cuttings may or may not develop roots; either way, planting the cuttings will cause the roots to grow. The Pencil Cactus exemplifies the latter.
I’ve been doing the pruning for more than a week now. My guest room’s floor is covered with the healing cuttings I picked from this plant. They don’t receive direct sunshine, only moderate light.
Although I could plant them right now, I’m going to wait until the first of March. By the way, I’ve discovered that when planted, larger stems perform just as well as smaller stems.
Keep an eye out for a post and video on how to grow and plant these Pencil Cactus cuttings.
What Happens Next?
It remains to be seen if the Pencil Cactus will continue to grow here. It provides a welcome splash of greenery just off the patio, so it’ll probably stay there.
For a little more shape, I might need to perform a tip pruning (tip pruning, in case you didn’t know, is the removal of the soft new growth by 1-6).
In conclusion, pencil cacti are forgiving of pruning and grow quickly. They can be pruned softly or very heavily, as I did. Just be mindful of the sticky sap and make sure you thoroughly clean your pruners before and after pruning. They are a pleasant plant to have in your collection and are simple to grow.
How should a pencil cactus be handled?
ADVICE: Keep your cactus away from air vents and cool drafts. The Pencil Cactus prefers dry, warm settings despite being extremely durable.
Always evaluate your plant’s watering requirements as soon as you get one. It is important to check the soil’s moisture content first to make sure it isn’t wet directly under the surface before giving your plant a drink. Additionally, think about aerating your plant’s soil before to the first watering. Aerating can help the soil breathe and enable rainwater to escape since we compact the soil to prevent it from shifting while being transported.
Between waterings, pencil cacti prefer to dry out entirely. Overwatering is the most frequent error with these plants. During the growing season, you won’t need to water your plant more frequently than once every ten days (at most). Watering should be done less frequently in the winter, perhaps even just once a month. Make sure you allow the soil to completely dry in between waterings. It is crucial that you do not water the plant if you notice any moisture in the soil since pencil cacti are prone to root rot.
When handling Euphorbia plants, exercise caution. The milky sap of the pencil cactus can produce mild to severe allergic reactions, especially in people who are sensitive to latex, despite the fact that it is a straightforward and uncomplicated plant from which to take cuttings and propagate. Use caution when handling your Pencil Cactus, gloves if you can, and be sure to properly wash your hands afterward.
To promote uniform growth on all sides, rotate the plant occasionally, and dust the stalks frequently to help the plant photosynthesize well. Take the chance to check the undersides of the leaves when dusting them and keep an eye out for bugs.
Keep in mind that every plant is a distinct living creature with different demands depending on where it is. You can have a long and fulfilling relationship with your pencil cactus if you pay attention to its health and its watering requirements.
Can I cut my cactus’ top off?
The enjoyable part is now. With the exception of damaged or dead stems and leaves, almost all of the material you remove is salvageable.
- If pads are placed on top of soil, they will take root and grow into a new plant of the same species.
- After several days, cut stems and trunks should be allowed to callus before being planted to grow new cacti.
- You should immediately pot up any offsets or pups that you remove from the specimen’s base because they are new plants in their own right.
- Compost is used for dead flower stalks and leaves, although certain cactus species develop leaves on the flower stem that can be treated similarly to other species’ pad material. Within a month, the majority of cactus portions will begin to root.
Once you’ve brought your first cactus back to life, you’ll enjoy creating more of the magnificent plant so you can add to your collection or give them as gifts to loved ones.
When do I cut back my cactus?
Knowing some of the reasons why cactus trimming is necessary, you now need to know when to carry it out. The top five indications that it’s time to prune your plant are covered in this section.
The plant has become too large
There are a few exceptions to the rule that most cacti species grow slowly and seldom reach destructive heights. When the correct conditions are present, members of the family of jungle cacti can grow too quickly.
As a result, if you want your plant to be asymmetrical but it is getting too big or one side is growing significantly quicker than the other, you may want to prune it back.
Normally, if you are pruning a plant to make it smaller, you should think about trimming the plant back by at least a third every year. A plant with regular trimming will eventually become slightly bushier and have more areas for blossoms to grow.
It’s a little simpler to maintain smaller plants because you may put them anyplace in your home. They can fit on your window sills without taking up too much of the small interior area.
Pest infestation
Some pests can still get to your plant even if the majority of cacti species have sharp spines that keep them away. Cactus bugs, mealy bugs, spider mites, cactus longhorn beetles, scale insects, and other common pests may attack your cactus.
Some of these insects reproduce quickly, and the results can be disastrous if you don’t move quickly to stop them. While the majority of them target the stems, some may also target the roots.
You must take the necessary steps to stop pest infestations as soon as you see them on your cactus. You may easily eliminate huge bugs by hand if they are an issue. You might have to hire a professional pest exterminator if they are little, like spider mites.
The bad news is that some bugs that affect cactus are so resilient and chemically resistant that not even the most seasoned pest exterminator can eradicate them. Pruning the damaged area is the sole option if you have tried hiring an exterminator but have not seen any effects.
Determine the area of the stem that was bugged, then carefully prune it back. To prevent re-infestation, be sure to prune the entire stem that is afflicted.
Top-bottom rotting
You must act quickly to address the frequent cactus problem of rotting if you want to keep your plant. Rotting may begin at the base (roots) and progress to the stem. It may also begin at the top and descend.
You may be dealing with tip rot, often referred to as cactus stem rot, if the tip of your cactus begins to turn brown and squishy. If you don’t move quickly to save the plant, your cactus will eventually die since once it begins to rot from the top, it won’t stop.
A fungus and pest infestation, as well as water infiltrating through an open wound on the plant, are the main causes of stem rot. Your cactus may be prone to stem rot if it has sustained any kind of harm.
The most crucial action you must take to save the remainder of the plant is to prune or cut down all compromised stem parts as soon as you see stem rot symptoms on your plant. If the rot isn’t removed by pruning, it will eventually kill your plant if you don’t.
Remember that rot spreads quickly, so there might not be much time left to preserve the cactus. To prune the stem’s impacted areas, use pruning shears or a sharp knife.
The appearance of dead stalks after blooming season
Another indication that you need to prune your cactus is the presence of dead flower stalks soon after the flowering season. This is especially true of the profusely flowering Christmas cacti.
To prevent losing the priceless blooms, don’t prune before the flowering season. But when the flowering season is done, you might see that the flower stems that are still there look unsightly. To give your cactus a fresh look, take your time and carefully prune them back.
In addition to getting rid of the dead stalks, pruning your cactus after the flowering period will also make it bushier, which will inevitably result in the formation of additional blooms the following year. Make sure to remove all of the diseased branches and dead stalks.
Cactus is getting too tall for its pot
Lastly, you should also consider pruning when you realize that your cactus plant is getting too tall for its pot. Every two to three years is the ideal time to repot your cactus, although this is not always the case.
As a result, if you see that your plant is growing too tall for its container, you should think about cutting it to prevent it from falling over. Plants cultivated in light plastic containers typically develop into taller, more slender plants. The plant can grow thicker and healthier if its height is appropriately reduced.
