The good news is that you can use neem oil on the majority of succulents without risk.
Neem can become a succulent’s best friend if you adhere to a few straightforward guidelines and keep an eye on how your plant responds.
Common Mistakes with Succulents
The majority of the horror stories you’ll come across online stem from a few simple errors.
The following are a few of the more typical ones:
- NEVER spray commercially available, pre-mixed neem on succulents. Neem oil starts deteriorating as soon as it is combined with water, so by the time you receive the product, it has probably severely deteriorated. Furthermore, you have no control over the ingredients in sprays that weren’t made by you.
- NEVER mist plants in direct sunlight. The majority of succulent plants may get severe leaf burns if their leaves become moist while being exposed to the noon sun, because Neem oil degrades when exposed to UV radiation.
- Before submitting a complete application, ALWAYS test. One cannot emphasize this enough, especially with regard to succulents. Never spray the entire plant with your neem spray; instead, apply a little amount to a single leaf or piece of stem and wait 24 hours to see if there is a negative reaction. You should adopt an alternative approach if the plant exhibits any signs of distress because this indicates an allergy or oversensitivity to neem.
- On delicate plants, NEVER use raw neem oil as a foliar spray. Azadirachtin can result in serious burns and is much more harmful than beneficial. Instead, save the raw Neem for soil soaks and just use the clarified Neem for sprays.
- Neem should NEVER be used with other liquids, even isopropyl alcohol. Additionally to occasionally causing a reaction, many of the web advice are detrimental to your plants. The only ingredient for neem oil that is thought to be secure when used as an emulsifier is insecticidal soap.
Neem Foliar Spray
Clarified hydrophobic neem oil is used in neem foliar sprays, the most popular type of neem therapy.
Azadirachtin has been mostly eliminated from this variety of neem, with only.5 to 3 percent Azadirachtin left.
When dealing with delicate plants, always aim for 1 percent or less until the infestation doesn’t show indications of abating after two weeks of treatment.
Emulsify 1 teaspoon of liquid Dawn dish soap, insecticidal soap, or pure castile soap should be added to 1 quart of water before gently blending.
Avoid spraying the flowers or the exposed roots, but make sure to catch the undersides of the leaves as well as any joints or crevasses.
For a total of 14 days or until the infestation has disappeared, repeat the treatment every other day.
In order to protect beneficial insects and reduce your danger of becoming sunburned, it would be best if you only sprayed at dark or morning.
In 45 to 1 hour, the neem will vanish completely, leaving no trace left.
Special Fungicidal Recipe
This mixture will work on many succulents to control external fungal diseases, but you will need to test each item separately for potential sensitivities.
If the infection hasn’t progressed too far, remove any dead leaves and clip away any clearly affected leaves; if it has, you might need to leave those leaves alone.
Next, add two teaspoons each of clarified Neem oil and either olive or almond oil, as well as one teaspoon each of rosemary and peppermint oils.
Neem oil—does it harm succulents?
Absolutely! For the majority of plants, neem oil works well as a pest deterrent. Its organic nature means that using it has no impact on the environment. The fact that it reduces egg production has advantageous uses as well.
In contrast to subjecting the plant to repeated chemical treatments from other pesticides, it produces a quick and effective recovery.
It also deals with common garden pests that cause problems for homes, such as Japanese beetles, snails, caterpillars, and even mosquitoes.
Neem oil can be used on cacti and succulents.
Although they are tough and able to withstand extreme weather, succulents are nevertheless susceptible to damage from pest infestation, and using neem oil effectively can help prevent such occurrences.
When applied to succulents, neem oil functions as a repellent and a way to stop pests by stopping the hormone that allows insects to feed. The oil’s active component Azadirachtin is responsible for this. For best results, use neem oil twice weekly as a foliar spray or soil drench.
Neem oil, which is derived from the neem plant, can protect your succulent plants from pests without having any negative effects.
Which plants should not be exposed to neem oil?
I started using neem oil in my garden a few years ago to get rid of spider mites and aphids, and I’ve grown to adore it. I’ve had great success using neem oil, which naturally repels insects, especially when it comes to keeping the pests away from my tomato plants.
But I recently discovered a hard lesson: Neem oil simply isn’t a favorite among all plants. Thus, the issue arises: Which plants should you avoid using neem oil on?
Herbs like basil, caraway, cilantro, dill, marjoram, oregano, parsley, or thyme shouldn’t be sprayed with neem oil. Neem oil should only be sprayed sparingly on plants with fragile or wispy leaves, such as spinach, arugula, lettuce, and peas, to avoid burning the foliage.
Be careful while mixing and applying neem oil, though, as even hardier plants with tougher foliage might be scorched (or even killed) if you don’t.
Neem oil is made to cover a plant’s leaves and any invasive insects lurking among them in an oily film that will suffocate some insects and harm many others by damaging their cells. Neem oil is an oil, though, so even on a moderate day, if you ignore good advise and spray at the wrong times, you risk literally cooking the leaves of your plants.
In light of this, let’s look at a list of plants that tolerate neem oil, those that are sensitive to neem oil, and those that don’t actually require neem oil because they already ward off many of the most pesky bugs.

Even if there are additional pests that may harm your succulents, the majority of infestations will be caused by one of these four bugs.
Mealybugs
The fluffy, white insects known as mealybugs are typically found in big numbers. Although you might mistake them for a spiderweb up close, they have a distinct, cottony texture.
They adore living in cracks and other secret, safe places. Check the areas of your succulents where the leaves meet the stem; this is a preferred location.
Fortunately, mealybug infestations are fairly simple to manage. You can just unpot the succulent and thoroughly rinse it out with a strong stream of water if the infestation isn’t too bad. That ought to be sufficient to remove all of the mealybugs.
You should repot the plant in new soil because certain species lay their eggs in the soil. If you’re unsure whether your soil is contaminated, you can bake it at 200 degrees for a couple of hours to eliminate any hidden pathogens.
Apply rubbing alcohol to the affected areas of the plant if water is ineffective or you don’t want to repot the plant. The insects will be instantly killed by regular 70% isopropyl alcohol, but your succulent won’t be affected at all. Try spraying the plant liberally with alcohol after filling a spray bottle with it.
Scale
On the plant’s surface, scales take the form of rounded or oval bumps. They are very little, measuring no more than one centimeter or so, and are always dark in color.
It should be immediately clear why these insects are called scales since they are protected by a hard, smooth shell. When they reach the adult stage, they choose a location (typically along the stem) and stay there for the rest of their lives. They are fairly resistant to chemical treatments and almost impervious to predators.
However, they usually spread very slowly. If you notice a few of them on your plant, you may remove them quite quickly by scraping them off with a blade or your fingernail. If there are numerous, you should use a potent insecticide.
The solution is neem oil. Neem oil is frequently marketed as an extract and needs to be diluted before usage, so be sure to read the instructions carefully. Additionally, keep in mind that if the oil is on the plant and under strong, direct sunshine, it could result in sunburns because it is an oil.
Neem oil should therefore be used at night. That also lessens the chance of accidentally catching helpful bugs, most of which are active during the day.
Spider Mites
Spider mites are extremely hardy because they can overwinter in the soil and reproduce swiftly. They flourish in the same hot, dry environments that succulents do, unlike the majority of pests.
The tangled, wispy cobwebs that spider mites build around themselves to ward off predators make them very easy to recognize. They come in a variety of hues, including brown, black, and red, and many of them are so tiny you would need a magnifying glass to see them. Look for webs on the undersides of leaves, where they almost always congregate.
Although they pierce leaves to get the juices, the damage is done gradually. For a plant to actually be in danger, spider mites would need to completely cover it. To identify spider mites, look for random spots of yellow, brown, or gray scarring on leaves.
Washing away their protective web covering with vigorous water is the first step in getting rid of them. Apply neem oil next as you would for scaling. Treatment with isopropyl alcohol is also effective. An additional choice is to use insecticidal soap, which you can either purchase or manufacture by combining a few drops of dishwashing detergent with a quart of water. Use a spray bottle to liberally apply the solution.
Fungus Gnats
In reality, fungus gnats are merely a nuisance and not even a pest. However, they are very common and should be mentioned.
They resemble fruit flies in every way, more or less. perhaps a little smaller When you brush by them, they will occasionally take off in a swarm when they are resting on the leaves of your plants.
The adult gnats you see flying around have a relatively brief lifespan and barely consume any food. They lay their eggs in wet ground. The eggs develop into larvae that primarily consume decaying matter but may eat new, sensitive roots if given the chance.
Although fungus gnats are not very harmful to your succulents and cacti, they are a sign that your plant is overly damp. Give the plant extra time to dry out in between waterings or switch out the soil with one that is looser and faster draining.
It is quite simple to get rid of fungus gnats. The soil will eventually die if you thoroughly dry it up (without any water for around two weeks). The eggs and larvae will shrivel up, and the adults will eventually pass away. If you place a fan to blow over the plant, the adults won’t be able to return and deposit eggs because they are extremely slow flyers.
Water your plant with an alcohol or insecticidal soap solution and fully wet the soil for a quicker fix.
That is the quick-and-dirty method for removing bugs from your cactus and succulents. Do you have any questions concerning any other pests? Do you require more information? Tell us in the comments section below!
How do I keep insects away from my succulents?
Due of how simple they are to maintain, succulent plants are among the most common houseplants in America. Succulents are popular houseplants that are difficult to kill but are very vulnerable to pests. Unfortunately, due to their delicate exteriors, which are easily harmed during extermination, succulent plants pose more of a pest control challenge than other plant types. You’ve come to the proper place if you lack extermination experience. Here are four procedures you should follow to get rid of pests from your favourite succulents.
Identifying the afflicted plants is the first step in a successful pest removal. Aphids and mealybugs are the two most prevalent pests that attack succulent plants. Your plants may be afflicted with aphids if you see small dots on them. Aphids need to be removed from your plants as soon as possible since they can cause significant damage by suckling out the juice from your plants. As an alternative, mealybugs harm succulent plants the most and cause fuzzy white lumps on plants. Mealybugs are sap-eating insects with toxic saliva that can stunt plant growth and even cause leaves to drop too soon. No matter what kind of pest you find, it’s critical to take immediate action to prevent spread and plant damage.
It’s time to isolate the affected succulents once you’ve identified which plants are contaminated in order to stop the bugs from spreading. You may keep a closer eye on your diseased plants by isolating them, and you can give the plants that are not responding to treatment more attention.
Before introducing any new succulents you buy to your other plants, it’s a good idea to quarantine them in a different room for a few weeks. Before adding the plant to your collection of other succulents, you can cure it and personally remove any insects that were there when you purchased the plant.
Taking precautions for your succulents is one of the best methods to keep pests away from them. Preventative action taken early on will help you avoid a major headache later on. Every time you buy a new succulent, you should give it a systematic insecticide spraying while the plant is confined. Your succulent will be made poisonous to bugs by the insecticide, preventing harm. When you re-pot your plants, it’s a good idea to spray them again.
Spraying one of your existing succulents with 70% alcohol is an excellent technique to treat it if you want to avoid using chemicals to treat the infestation. Make sure to approach the plant from every possible aspect when doing this. If alcohol is unsuccessful, further options include using insecticidal soap, a solution of dish soap and water, or an insecticide spray. You can put your plant back with the others after it has been bug-free for 30 days.
Pests don’t necessarily disappear permanently just because you got rid of them from your succulents once. After all, plants are highly attractive to pests. Regularly inspect your succulents for signs of pests, and immediately quarantine any infected plants.
Repeat steps one through four if you discover pests in your succulents again. Use a professional pest control company’s services if you can’t get rid of the pests yourself.
There are steps you can take to lessen the likelihood that pests will harm your succulents, even though you cannot completely prevent this from happening.
- Take out the dead leaves to make it harder for bugs to hide and reproduce. Eliminating dead leaves will also lessen the possibility of mold growth.
- Keep your succulents as dry as possible. Pests tend to be drawn to moist soil.
- Reusing soil or adding dead leaves from diseased plants to the compost pile are also prohibited.
- During the growing season, keep your succulents healthy by fertilizing them with a gentle, balanced fertilizer.
