Epsom Salt: A Natural Way to Control Cutworms

According to LawnStarter, there is no clinical proof that Epsom salt can virtually kill cutworms (or any bugs) on touch.

Essential Home and Garden indicates Epsom salt as a normally recommended family substance for lawn use, but it does not guarantee its effectiveness in opposition to cutworms.

Getridofallthings.Com reports that research shows Epsom salt is ineffective in opposition to cutworms and different insects, and excessive use might not yield superb results.

True Leaf Market mentions that at the same time as some gardeners have had achievement treating cutworms with Epsom salt, it is nonetheless unclear whether or not it clearly works or no longer, and its efficacy remains a topic of debate among gardeners.

Epsom Salt and Cutworms

For a variety of garden pests, including cutworms, Epsom salt is often recommended as a natural treatment. Experts and gardeners disagree on the efficacy of Epsom salt in controlling cutworms. While some sources assert that Epsom salt helps prevent or kill cutworms, others contend that it may not be particularly helpful and may even be bad for plants.

Those who favor the use of Epsom salt for cutworm control contend that the salt’s abrasive texture may damage the cutworms’ fragile bodies, causing dehydration and finally death. They advise scattering Epsom salt around plant bases to provide a barrier that prevents cutworms from passing.

Epsom salt’s effectiveness in controlling cutworms is, however, only partially supported by scientific research. Many scholars and gardening specialists have voiced doubts about its efficacy. Epsom salt seems to be ineffective against cutworms and other insects, according to research from Washington State University (WSU).

Furthermore, putting too much Epsom salt in the garden may endanger the grass and plants. Epsom salt contains magnesium sulfate, which may increase the mineral pollution of groundwater. Spraying Epsom salt solutions on plant foliage may also burn the leaves.

There are a number of different natural approaches that may be successful in controlling cutworms, even though Epsom salt may not be a dependable answer. Here are some other tactics you may want to think about:

  • Physical barriers: Use collars made of cardboard, foil, or plastic cups with the bottoms cut off to surround each plant with protection. Cutworms cannot get to the plants because of this.
  • Use diatomaceous earth (D.E. ), a natural powder derived from ground-up diatoms, to surround plant stems. The sharp particles in DE cause dehydration and death in cutworms when they come into touch with them.
  • Introduce helpful insects to your garden, such as parasitic wasps or nematodes. These predators may aid in the population control of cutworms since they naturally feast on them.
  • Handpicking: Check your plants often for cutworms and personally remove them. Although this procedure requires considerable dedication, it may work for small-scale infestations.
  • Crop rotation: Use crop rotation to break the cutworm’s life cycle. Aim to avoid growing sensitive crops in the same spot every year.
  • Clean away any plant remnants, weeds, or garden detritus that might serve as a haven for cutworms and their larvae.
  • Plant flowers or herbs that draw beneficial insects like ladybugs, lacewings, and ground beetles to attract natural predators. Insects like this may help control the population by eating cutworms.

Keep in mind that the best approach to manage cutworms is prevention. You may reduce the possibility of cutworm infestations by keeping a healthy garden environment, encouraging biodiversity, and putting good cultural practices into practice. Consider seeking additional help from a local agricultural extension office or a professional gardener if the infestation gets serious or continues in spite of your efforts.

Why Epsom Salt is Bad for Plants

One of the main reasons why Epsom salt can be bad for plants is its impact on calcium uptake. Epsom salt has a lot of magnesium, which might prevent plant roots from absorbing calcium. Calcium is crucial for the growth of root systems, cell walls, and general plant health. The disruption of calcium absorption may result in a number of problems, including tomato blossom end rot and other calcium-related deficits.

The possibility for leaf scorch while using Epsom salt is another issue. Spraying Epsom salt solutions onto plant leaves may harm them and result in scorching or burning of the foliage. Plants may become more vulnerable to pests and diseases as a result, since pathogens may enter via broken leaves.

Additionally, using large amounts of Epsom salt might worsen the mineral pollution of groundwater. This may have a detrimental impact on plant growth and development by causing nutritional imbalances in the soil.

It is crucial to remember that plants have particular nutritional needs, and adding Epsom salt without first analyzing the nutrient profile of the soil might do more damage than benefit. Conducting a soil test to identify the precise nutritional requirements of your plants is advised before introducing any amendments or fertilizers.

Epsom salt may be helpful in certain circumstances, such as correcting magnesium deficiency in particular plants or soils, but it should only be used when there are true nutritional shortages that have been detected by soil testing.

It is often more efficient to maintain healthy soil by adding organic matter, adhering to regular watering procedures, and applying balanced fertilizer based on the findings of soil tests rather than exclusively depending on Epsom salt. This method guarantees that plants get the required nutrients in the right amounts, enhancing the general health and vitality of the plant.

How to Use Epsom Salt as a Pest Repellent

Some gardeners have taken to using Epsom salt as a pest deterrent in their gardens. Epsom salt is typically used as bath salts and as a natural pain reliever for aching muscles, but it is also said to have insect-repelling qualities. However, it’s critical to comprehend the limits and appropriate use of Epsom salt as a pest control technique.

Making a solution of Epsom salt and water and sprinkling it over plant leaves is one typical way to use it as an insect repellent. One cup (240 ml) of Epsom salt to five gallons (19 L) of water is the suggested ratio. Before transferring the salt to a pump sprayer for spraying, it must be completely dissolved in a large bucket or container.

It is claimed that the abrasive texture of Epsom salt might scare off pests like beetles and other garden insects. When sprayed on foliage, the remedy may make conditions unpleasant for these pests, so minimizing their presence in the garden.

It’s crucial to remember that there is no scientific evidence to support the usefulness of Epsom salt as a pest deterrent. While some gardeners report successful outcomes, others may not have as much luck. Depending on the individual pests in your garden and the surrounding circumstances, Epsom salt may or may not be effective as a pest control approach.

It’s also important to think about any possible disadvantages of utilizing Epsom salt as a pest deterrent. First of all, it’s crucial to avoid using the solution while it’s bright and sunny outside since it may harm plant foliage or produce scorched leaves. Second, using Epsom salt excessively may contaminate the soil and water that percolates through it with minerals. This may have a detrimental impact on plant health and development by causing nutrient compositional imbalances in the soil.

It is important to note that there are other, more well-known and efficient approaches to pest control in gardens, such as integrated pest management (IPM) techniques. Through a mix of cultural, mechanical, biological, and chemical control strategies, IPM focuses on identifying and managing individual pest challenges. These techniques are often specialized to focus on certain pests while minimizing damage to beneficial insects and the environment.

Alternatives to Epsom Salt for Cutworm Control

There are a number of excellent alternatives to Epsom salt when it comes to controlling cutworms in the garden. Cutworms are a common pest that may seriously harm young seedlings by slicing through the stems at the soil’s surface. Here are some substitutes to take into account:

  1. Diatomaceous earth (DE) is a natural powder that is created from the fossilized remnants of small aquatic creatures called diatoms. It has a rough texture that may keep cutworms and other pests away. To keep cutworms away from seedlings, either place a barrier around them or sprinkle a thin coating of DE around the base of the plants.
  2. Coffee grounds: Coffee grounds may act as a natural cutworm prevention. At the base of plants, scatter some coffee grinds or incorporate them into the soil. Coffee grinds’ strong aroma and acidity may deter cutworms.
  3. Another common home ingredient that may be used to keep cutworms away is baking soda. Sprinkle flour and baking soda in an equal mixture around the bases of plants. Ingesting the combination might cause the cutworms’ digestive systems to malfunction.
  4. Crushed eggshells may serve as a physical barrier to keep cutworms away from plants. Create a protective ring around the plants or place crushed eggshells around the base of seedlings.
  5. Beneficial nematodes are tiny worms that are effective in controlling cutworms biologically. Cutworm populations in the soil may be decreased by these nematodes, which are natural predators of cutworms. For correct application, adhere to the instructions that came with the nematodes.
  6. Products containing spinosad: A soil bacteria is the source of spinosad, a natural pesticide. Cutworms are only one kind of garden pest that it is effective against. Look for products with a spinosad basis that are specially labelled for cutworm control, and apply them according to the directions.

It’s crucial to remember that depending on the particular circumstances in your garden and the degree of the cutworm infestation, the efficacy of these solutions may vary. To obtain effective control, it could be essential to mix several techniques or test out various strategies. Furthermore, cutting down on cutworm habitat and food supplies by maintaining proper garden cleanliness practices including eliminating weeds and plant waste.

FAQ About Using Epsom Salt for Cutworms

Is Epsom salt safe for worms?

Epsom salt is often thought to be harmless for worms, although very high concentrations of it may be poisonous to them. Earthworms aerate the soil and break down organic debris, which is essential for sustaining healthy soil. They are crucial for the soil’s general health and the cycling of nutrients. Even though magnesium and sulfur, two vital minerals for plants, are present in Epsom salt, it is better to use it sparingly and only when a soil test shows a magnesium shortage.

Although there is no scientific proof that Epsom salt would kill earthworms, some gardeners think it could be harmful to them. Due to their soft and delicate skin, earthworms may get dehydrated or irritated when exposed to excessive Epsom salt concentrations. As a result, it’s crucial to refrain from using large amounts of Epsom salt in garden areas where earthworms are abundant.

Apply Epsom salt carefully and adhere to specified dosage amounts if you’re thinking about utilizing it in your garden and want to preserve the earthworm population. The easiest approach to find out whether your soil really needs more magnesium is to do a soil test. You may apply Epsom salt in accordance with the specified dose and instructions if the test indicates a deficit.

As an alternative, you may concentrate on preserving soil health using natural methods that support a healthy earthworm population. Composting, mulching, and minimizing the use of chemical pesticides are all methods that may help to improve the environment for earthworms and other beneficial creatures.

What plants don’t like Epsom salt?

While Epsom salt can be beneficial for some plants, there are certain plants that don’t respond well to its use. Here are some examples of plants that don’t like Epsom salt:

  1. Beans and Leafy Vegetables: Beans and leafy vegetables are susceptible to elevated magnesium levels. Examples of these veggies are lettuce and spinach. Epsom salt overuse may cause nutritional imbalances and impede the development of certain plants.
  2. Coniferous Trees: The use of Epsom salt is not appropriate for coniferous trees, such as pine, spruce, and fir trees. These trees thrive on acidic soil, which Epsom salt may change to be inappropriate for their development.
  3. Tropical Palms: Epsom salt does not work well on tropical palms like fiddle leaf figs, monstera, and philodendron. These plants may be sensitive to the extra minerals in Epsom salt since they have evolved to flourish on nutrient-deficient soils.
  4. Plants That Eat Insects: Epsom salt should not be used on carnivorous plants including pitcher plants, sundews, and Venus flytraps. These plants demand certain nutrients and have evolved to flourish in nutrient-deficient soils. Epsom salt consumption has the potential to damage them by upsetting their delicate equilibrium.

Can I apply Epsom salt directly to my soil?

Yes, you can apply Epsom salt directly to your soil. It can be added to the soil when planting or worked into the soil without diluting it in water first. Here are some tips for using Epsom salt in your garden:

  1. When planting, you may immediately mix Epsom salt into the ground. Include it in the soil close to the plant’s root zone.
  2. Epsom salts may also be dissolved in water and applied to the soil as a drenching agent. Water the plant at the soil level while adding the necessary quantity of Epsom salt to the water and applying it to the soil.
  3. Potted Plants: For potted plants, you may use this solution as a replacement for regular watering once a month by dissolving two teaspoons of Epsom salt in a gallon of water. This aids in supplying sulfur and magnesium to the plants.

While Epsom salt may be advantageous for certain plants and soils, it should be applied sparingly and in the proper quantities. Epsom salt may not always have the expected effects and excessive usage may result in nutritional imbalances. Before using Epsom salt, it is usually essential to do a soil test to see whether your soil is magnesium deficient.

Additionally, using Epsom salt won’t be advantageous for all plants. Some plants could be sensitive to high magnesium concentrations or have particular nutritional needs that Epsom salt cannot satisfy. For advice on using Epsom salt or any other amendments in your garden, it is advisable to do study on the particular requirements of your plants and speak with gardening professionals or your local agricultural extension services.

What is a homemade remedy for cutworms?

Cutworms can be a frustrating pest in home gardens, but there are several homemade remedies that can help you protect your seedlings and get rid of these destructive insects. Here are some effective methods you can try:

  1. One of the easiest and fastest fixes is to personally remove the cutworms from your plants. Pick them off and place them into soapy water. With a flashlight, go outside to your garden in the nighttime and remove each cutworm one at a time. Dropping them into a bucket of soapy water will cause them to drown and die. To keep the population under control, repeat this procedure a few nights in a row.
  2. Diatomaceous earth (D.E.) is a natural powder formed from ground-up diatoms that may act as a cutworm barrier, hence it should be used to surround stems. The cutworms will need to crawl past a physical barrier that you will create by scattering diatomaceous earth around the base of your plants. The D.E. kills insects when it comes into touch with them because the fine powder penetrates their exoskeleton and causes them to finally become dehydrated. Reapply the D.E. after irrigation or rain, don’t forget.
  3. Cornmeal: Cornmeal is another all-natural treatment for cutworms. Because cutworms cannot digest cornmeal, eating it makes their stomachs expand and ultimately kills them. Around the base of your plants, scatter a little quantity of cornmeal, paying particular attention to the cutworms’ breeding grounds. Apply the cornmeal again as necessary, particularly after rain or irrigation.
  4. Plant collars: Cutworms often nibble through plant stems, dismembering the plant. You can build physical barriers like plant collars to stop this. Make sure they stick out a few inches above the soil level by cutting tiny chunks of cardboard or plastic cups and inserting them into the soil around the stem of your seedlings. By doing this, you can keep cutworms from getting to the stems and keep them from eating your plants to death.
  5. Beneficial nematodes are tiny roundworms that feed on a variety of pests that live in the soil, including cutworms. These nematodes are available at garden supply shops; use them in your garden soil in accordance with the directions on the box. The nematodes will seek out the soil-dwelling cutworm larvae and infect them, ultimately killing them. When the soil temperature is more than 50°F (10°C), this technique is most successful.
  6. Maintaining proper garden cleanliness might assist to cut down on the number of cutworms. Cutworms may hide throughout the day in garden detritus like fallen leaves and plant remains. Maintain order and cleanliness in your garden area to reduce their hiding spots.
  7. It’s vital to remember that some home remedies may need to be used more than once and continually monitored in order to have the desired effects. Additionally, combining several approaches may often be more successful than depending just on one. You can think about applying organic or synthetic pesticides with a label for controlling cutworms if the infestation continues or becomes out of control. When using a product, always follow the directions on the label and think about choosing more ecologically friendly solutions.

What kills cutworms in soil?

Cutworms can be a common and destructive pest in soil, but there are effective methods to kill and control them. Here are some approaches you can take to get rid of cutworms in the soil:

  1. Beneficial nematodes are tiny roundworms that may be introduced into the soil to hunt out and eliminate cutworms. In the spring, when cutworms are most active, these nematodes are most helpful when added to damp soil. The nematodes locate the cutworm larvae in the soil, infect them, and finally kill them. Plants, people, and other helpful insects are all unaffected by this biological control strategy.
  2. Cutworm eggs are the focus of Trichogramma wasps, which are microscopic parasitic wasps. These wasps, when released into your garden, deposit their eggs within the cutworm eggs, preventing the eggs from developing and lowering the number of cutworms. When you first observe indicators of cutworm activity, such as moths, it is advised to release trichogramma wasps once a week for three consecutive weeks.
  3. Solution of soap and water: Washing your plants with a mixture of water and dish soap that doesn’t include bleach will help prevent cutworm attacks on your plants. Spray the concoction on your plants, paying particular attention to the lower stems and soil surface where cutworms are most likely to be present. The soapy solution kills the cutworms instantly by choking them.
  4. Physical removal: You may physically get rid of cutworms by hand if you find them in the soil. Digging gently around the afflicted plants, remove the cutworms, and place them into a pail of soapy water. Although it may take some time, this strategy may be successful in lowering the number of cutworms.
  5. Plant collars and barriers: Surrounding your plants with physical obstacles will help keep cutworms away. Create plant collars out of cardboard or plastic cups, then wrap them around your seedlings’ stems. By serving as a barrier, these collars stop the cutworms from getting to the plants and inflicting harm.
  6. Good garden hygiene: Maintaining good garden hygiene may aid in the long-term control of cutworm populations. Cutworms may hide throughout the day in garden detritus like fallen leaves and plant remains, so remove it. Early spring and late autumn tilling may also assist in exposing cutworms to predators and poor weather conditions, hence lowering their population.
  7. Chemical insecticides: Although using natural ways is preferred, chemical insecticides are still a viable option for killing cutworms. Look for pesticides with labels for controlling cutworms and carefully follow the directions. Cutworm control pesticides like imidacloprid and bifenthrin are often suggested.


Epsom Salt: Does it Really Work for Cutworms?
