Spraying or mechanical removal using a grubbing hoe (for isolated plants) or a skid-loader are the two methods that are typically advised for getting rid of prickly pear (large stands). Occasionally, controlled burns can be employed, but fire is not selective and burning needs a lot of supplementary dry brush (cactus don’t burn well). Burn prohibitions that are in effect across a large portion of the Southwest United States also rule out most people using this technique.
Depending on the scale of the cactus growth and the surrounding vegetation, spraying and grubbing each have their own advantages and disadvantages. Rainfall and temperature can also affect how well your strategy works. Cost might also be a significant factor.
Grubbing or the top-removal method
The most efficient, speediest, and environmentally responsible method of removing substantial stands of pricklypear is generally thought to involve digging up cactus with a skid-loader. However, it can be expensive, with charges for the operator and equipment ranging from $80 to $100 per hour. For tackling substantial cactus stands, Michael Dalrymple, a Mills County, Texas, contractor who specialised in brush removal, advises using a skid-loader fitted with a rock rake. The rock rake’s tines allow dirt to fall back to the ground, decreasing top soil loss and disposal weight in the process. Using this method, the operator is able to cut out several inches of the root, which is sufficient to kill the plant.
In order to bury the uprooted cactus, Dalrymple advises trenching a pit and adding 18 to 24 inches of earth. Cactus that has been heaped up will re-root and develop into an impenetrable mound, unlike cedar that can be stacked up and burned.
It’s crucial to gather as many of the dropped pads as you can. Every pad that is left on the ground has the capacity to take root and grow into a new cactus.
Although mechanical removal can be done at any time of the year, the best times are fall and early winter to allow for reseeding in time for the growing season.
Herbicides
Spraying works well on single plants and lean pricklypear growths. With ground-level spraying, it is practically impossible to completely remove a large, thick stand because pads and stems must be thoroughly coated. Additionally, it’s crucial to avoid spraying close to mature trees and vegetation because those plants’ roots can absorb the toxin.
Large stands of cactus that are far enough away from trees and other valuable flora that the herbicide drift won’t harm or kill are occasionally advised to be sprayed from the air.
Although cacti can be sprayed at any time of the year, most experts advise spraying herbicides in warm weather when rain is forecast since moisture makes the poison easier to absorb.
Results can take six to eight months to appear, and many applications are frequently needed to completely eradicate the cactus.
Although the Dow AgroSciences subsidiary of Dow Chemicals produces a number of efficient herbicides, two of the best-known, Tordon 22K and Surmount, are limited by the federal government and need a licence to be used. For spot maintenance, several ranchers advise Dow’s PastureGard HL herbicide because it can be applied without a licence. Employing a licenced applicator can cost upwards of $35 per hour plus the herbicide depending on where you live.
What causes prickly pear cactus to die?
SurmountTM, a herbicide that combines fluroxypyr and picloram, the sole active component of Tordon 22KTM, is the one suggested in Brush Busters. Although prickly pears are notoriously slow to age, SurmountTM pads age and melt down more quickly than Tordon 22KTM pads (approximately a year) (about 2 to 3 years).
Does Roundup destroy prickly pear cactus?
In some circumstances, using chemicals to control infestations is the best course of action. Currently, glyphosate and monosodium methanearsonate (MSMA) are approved for the management of prickly pear. Both of these herbicides need to be injected as concentrated solutions into plant stems.
How can prickly pears be avoided?
The use of fire to eradicate extensive prickly pear infestations is effective. Ask Biosecurity Queensland if burning is appropriate for your pasture and land management techniques before you do it.
Cacti in your yard: how can you get rid of them?
There are primarily two methods for doing this. The first method is to remove them using chemicals. Physical removal is the second technique. Either approach can be risky if used incorrectly, but both are generally safe if used correctly.
What you should know about both techniques for clearing cacti from your yard is as follows:
Killing a Cactus with Herbicide
Herbicide combinations come in a variety of forms with varied components. Picloram is one such component that you should keep an eye out for. A large fraction of some varieties of cactus can be eliminated with the aid of a herbicide containing picloram.
To aid in absorption, some experts advise incorporating a small amount of dish soap into your picloram herbicide mixture. Since you’ll be spraying it on your cactus, it’s also a good idea to apply some dye. The dye will show you which places you’ve covered and which areas you’ve missed. Blue is a useful dye colour to use:
It will assist if the plant is physically harmed before you spray this on the cactus. To make some nicks in the cactus so that the spray may better penetrate the plant’s interior rather than just sitting on the exterior, you can use any form of axe, a shovel, or any pointed object.
Although the insider information helps move things forward more quickly, the parts you spray on the exterior will still be effective.
How to Get Rid of Cactus Without Chemicals
Overwatering cacti or succulent plants is the most typical technique to harm them. Cacti that receive too much water will become mushy and essentially decompose. That doesn’t really help you much in this situation because you still need to dispose of it, which brings us to the main problem with this strategy.
Physical removal, or just getting rid of a cactus, is your only option if you don’t want to employ chemicals to deal with it. After that, you may either discard it in the garage or dispose of it as regular yard garbage.
Depending on where you reside, different cities will give varying guidance or services for this, so you might want to check your local laws. Because it is organic and contains a lot of water, cacti typically shrivel into a much smaller state over time. Be careful, though, because it will be really sharp in the interim.
One part gin, one part vinegar, and one part water make up a DIY cactus killer recipe. This can be put in a spray bottle, sprayed, or poured over the plant’s base.
Here are some helpful suggestions on how to remove a cactus from your yard safely and effectively if you want to avoid using chemicals.
How to Remove a Cactus From Your Yard
After spraying, you still need to get rid of the plant once it has died. In fact, you still need to get rid of it whether or not you sprayed it. Here are some ideas on that as well as advice for getting it off the ground.
The degree of defence you’ll need against its thorns will mostly rely on how big the cactus is, how many of them there are, and what kind they are. Some are far pricklier than others!
The first step is to make sure that you have no exposed flesh anywhere on your body since pricklies are drawn to exposed skin like a magnet. Wear protective eyewear. Put on sturdy boots or shoes, preferably ones with a thick rubber sole.
It is beneficial to cut up a huge cactus when working with it (carefully.) For this, you can use almost any kind of shovel or a blade of some sort, like a machete. Be cautious as you swing and hack at it; at the very least, you should wear eye protection, and if not that, a full face mask.
Murphy’s Law holds that if there is any region of exposed skin on your body, even if it is only covered by a t-shirt, you will inevitably get stung by a cactus there.
Therefore, start by carefully wrapping some of the pieces you remove by chopping at it. Put on thick, hefty gloves with plenty of wrist and arm protection. You’ll be safer if your clothes is more substantial and dense.
The bits you take out of the cactus store up well in cardboard boxes. It’s time to start digging when all that’s left is the plant’s underground roots and bottom portion.
As much of the root system as you can should be dug up. The more you may get, the less probable it is to continue existing, let alone thriving or regrowing. Its size will vary from plant to plant.
Supplies
- A shovel
- An axe or chainsaw (for huge cacti) (for large cacti)
- Pruning scissors (for small cacti)
- an outdoor hoe (optional)
- hefty gloves
- an oversized shirt
- lengthy pants
- Planting boots
- protective eyewear
- a few heavy cardboard crates
- Tweezers
- an enlarging lens
- serving forks
Steps
Dress Properly.
Put on safety clothes before continuing. Wear long sleeves, long pants, gardening boots, and heavy gloves similar to those described in this article about the best gardening tools. It’s a good idea to use safety eyewear as well, especially if you want to cut a sizable cactus.
Use an axe, chainsaw, or pruning shears to remove the cactus.
For a large cactus, an axe or chainsaw will be more effective, although these pruning shears will do for a tiny cactus. Cut off a small portion of the cactus at a time, beginning at the top, until you reach the soil line. It could fall on you if you cut it from the base. The severed parts can be gathered together using a garden hoe. They should be placed in a sturdy cardboard box using salad tongs. Any that you leave on the ground can develop into more cacti.
the primary root,
Dig around 2-4 inches (5-10 cm) into the ground with a shovel. Use the shovel or axe to cut through the main root once you’ve located it.
- Remove the Roots
- Take out the needles from your shoes and clothing.
- Carefully dispose of the boxes
Get rid of the cartons containing the pieces right away. The cardboard boxes’ interior cactus bits may take root in the earth if they soften and disintegrate. Be mindful of garbage crews who may nick themselves on the debris. This might occur if the boxes get wet or if you don’t properly seal them. Tape the boxes shut and place them in a trash bin if you anticipate that a garbage staff will manually load them into a truck. The best location for the boxes, though, is in a garbage container or dumpster that will be automatically emptied.
Rate of growth and spread
Segments or fruit that fall to the ground and take root cause localised plant dissemination around existing clumps.
This weed can spread over long distances in a number of methods. Seeds are spread over distances of more than 1 km with the help of animal droppings from foxes, birds, and other animals.
Flood waters go great distances carrying fruit and detached segments. Small prickly pear (erect) segments and fruit can also stick to animal fur and hides, as well as to clothing, tyres, and footwear.
A major source of new infestations in urban areas is human movement of plant parts, whether through the promotion of this plant as an ornamental or hedge plant or the disposal of it in landfills and waste sites.
Seedbank propagule persistence
Each fruit of the prickly pear (erect) has a large number of seeds, and the plant itself yields a large number of fruits. This herb lives a long time. Individual plants can live for several decades if they are established.
Preferred habitat
Warm temperate and subtropical locales with subhumid to semi-arid climates are preferred by the prickly pear (erect). It generally grows along the banks of streams, where it encroaches onto nearby grazing area.
Cacti can vinegar harm them?
Succulent weeds and other weeds of all kinds have long been managed using vinegar. Cactus plants can be killed by adding 1 tablespoon each of gin and vinegar to 1 quart of water. Add 1 tablespoon of mild dish soap to the DIY weed killer to aid in adhesion to the wild cactus. Before planting in the area, wait a few weeks after using the homemade weed killer. To get rid of wild cactus more effectively, you should think about hand removal as it could take several tries to destroy the cactus with the vinegar mixture.

What depth do prickly pear roots reach?
Abstract:
Cacti have shallow roots, with the average depths for their diverse native Sonoran Desert species ranging from 7 to 11 cm and 15 cm for cultivated opuntioids; the cultivated vine cactus Hylocereus undatus has even shallower roots.
Although this shallowness makes it easier to absorb water after light rains, it also exposes the roots to high temperatures near the soil surface.
Extreme temperatures reduced the uptake of the essential stain neutral red into root cortical cells, with 50% inhibition (LT50) occurring for Nopalea cochenillifera, Opuntia ficus-indica, and O. robusta at an average of 7C for low temperatures and 57C for high temperatures, and for H. undatus growing at a moderate day/night air temperature of 25/20C, at 2C and 52C, respectively. The opuntioid LT50s showed seasonal adaptation to changing ambient temperatures, declining 1.2C as day/night air temps were lowered by 20C and rising 4.4C as they were raised by 20C.
In order to measure root growth, respiration, and layers with deadly temperatures, an equation is proposed to estimate soil temperature as a function of soil depth and time.
In this regard, the ability of most cacti to be cultivated today and in the future should not be constrained by the roots’ sensitivity to low temperatures.
Although fewer cacti roots may be found in the topmost soil levels as a result of rising air and soil temperatures brought on by global climate change, other (non-CAM) perennials should experience far larger restrictions.
