Rake Your Mulch Regularly

How to Rid a Garden of Fungus : Grow Guru

Use a rake to fluff-up your mulch once a week. This way, you are ensuring that the mulch is aerated and does not retain too much moisture, and it also breaks up any mycelia that might have started forming underneath. Often, it can take several weeks before you will see the actual mushrooms pop up in the mulch, and by then, you could have an extended network of roots that will be more difficult to manage.

How To Get Rid Of Them

Here are a couple of things to do when fungus growing in garden soil:

  • You should identify the sick affected plants first. Then dig the soil under the plants and remove the sick plants. Throw them in garbage cans to prevent the fungus from spreading again in healthy plants.
  • Always try to eliminate all the garden debris after you collect the crops or vegetables. You can do it at the end of the cyclic season. Then take the soil and transfer the waste to the basket. The fungus may bear again if the dead plants get water or dews in the winter season.
  • You may plant the plants in different areas of the garden. As an example, plant tomatoes in such place where you cultivated marigold in the last season. You may pause planting for several months after last season. During these periods, you can plant them in containers.
  • You may plant different plants as variations in the same field. Veggie and herb variations would be a great example. It can prevent soil-borne diseases.
  • Try to stop using so many fertilizers in the soil. The fungus may feed on the fertilizers. Instead, use organic and natural fertilizers to plant the crops or vegetables.
  • Spray water in a proper way. Over-watering or soggy soil is one common reason for planting fungus alongside the targeted plants.
  • The last solution can be using soil fungicide treatments. They are the best and durable solutions to kill all the fungus in the garden soil.

How To Destroy Fungus In Soil

You can destroy the fungus in your soil with a simple and chemical-free process known as solarization. This sun-powered technique enables high temperatures to kill the fungi in the soil and to help prevent diseases in subsequent plantings. Proper solarization eliminates at least 90 percent of fungus that thrive in temperatures up to 104 degrees Fahrenheit, including Phytophthora root rot and wilt caused by verticillium and fusarium. The best time to solarize your soil is during the hottest weeks of the year, typically between June and August.

Using Organic Fungicide Recipes

Now that youve learned how to make your own fungicide, use it responsibly. The term organic leads some to believe that these mixtures are completely safe, which is untrue. Use all homemade fungicide for the lawn and garden carefully, especially around children and pets.

BEFORE USING ANY HOMEMADE MIX: It should be noted that anytime you use a home mix, you should always test it out on a small portion of the plant first to make sure that it will not harm the plant. Also, avoid using any bleach-based soaps or detergents on plants since this can be harmful to them. In addition, it is important that a home mixture never be applied to any plant on a hot or brightly sunny day, as this will quickly lead to burning of the plant and its ultimate demise.

Castile Soap Essential Oil Solution

If you see large numbers of fungus gnats, then one organic insecticide to try is a castile soap solution. For those of you who do not know, this is not a generic soap. Castile soap was made in the Mediterranean area before its use spread to Europe. Traditionally, castile soap was made of olive oil. It gets its name from the Castile region of Spain.

Castile soap is produced based only on vegetables with no animal fat or synthetic ingredients. This is a 100% organic soap that will not damage the environment when it ends up in the drain. It is not toxic, and it is usually sold both in liquid and solid form. These days, the soap is also made with coconut, castor, or hemp oils. Sometimes its made with avocado, walnut, and almond oils as well.

Castile soap is not meant to be used as an insecticide but mainly as a body cleaning product due to its lathering, moisturizing, and cleansing properties. However, there are more than 20 uses of this soap, from deodorant, dish soap, shampoo, body wash, and plant spray for bugs.

In case you want to use this soap as a fungus gnats killer, here what to do:

  • Add 2 teaspoons of castile soap to 1 quart of water.
  • Place this mix into a spray bottle, and shake well.
  • Apply the mixture to just one leaf and wait a few hours. This is just a test as some plants might be damaged by the soap .
  • If there is no damage, spray this mixture onto your pots, soil, onto the leaf of the affected houseplants, and all surrounding plants .
  • No Biological Method For Getting Rid Of Fungus Gnats

    The methods discussed so far were 100% biological. Hence, substances found in nature and not produced almost from scratch. However, if you are not very into bioproducts, there are a few man-designed pesticides that can be quite effective in getting rid of fungus gnats.

    Mosquito Bits

    This product is a kind of biological control specially designed for indoor use. It comes in the form of small bits coated with the bacteria Bacillus thuringiensis subspecies israelensis. We discussed these bacteria before. It does produce toxins that kill larvae in the soil.

    The best way is to drop around 2 tablespoons in a container with half a gallon of water. Stir it if and leave it there to soak for 20 minutes. The solution so obtained can be applied to water the plants whose soil is infested with fungus gnats larvae. After several waterings, the gnats were gone. This solution is not harmful to pets, humans, just to the larvae.

    Generic Insecticide

    One note of caution here. Using insecticides to deal with insect infestations is not always the best policy. Remember, insecticides are indiscriminate and will kill insects you do want and those you dont.

    For example, if you grow tomatoes or other fruits or flowering plants indoors, pollinators may be required. Even if you take pollination into your own hands, letting in a few predatory insects can make it far easier to deal with aphids and other common pests organically. Often, it is best to simply live and let live.

    Treat Soil In Early Spring To Avoid Fungus Later In The Season

    Is there anything to treat soil in early spring, so that I do not get fungus on my tomato leaves later in the growing season?

    Any reasonable suggestion/advice welcome.

    Anna – the most common tomato fungal diseases are caused by fungi that are also airborne. Treating the soil with fungicides early in the spring may eliminate ‘some’ of the spores on the soil surface but would have no effect on those deeper in the soil that can be stirred up at any time. And the airborne spores can travel for miles so within days or even hours the area is re-infected.

    Fungal diseases are best prevented by using IPM multiple tactics – site selection for maximum sun exposure, no over-crowding of plants, improving air circulation among the plants with proper orientation to the prevailing winds, mulching the plants, and most importantly, spraying fungicides on the plants themselves from day one of planting.

    Remove any dead plant matter from in and around your hydroponic garden. Do this frequently since the fungus gnats feed and lay eggs in wet, decaying leaves and clippings. Dispose of everything you remove immediately by bagging it and taking it away from the area your hydro garden is in.


    Set yellow sticky traps in and around your hydroponic setup to catch adult fungus gnats.


    Prevent your hydroponic systems from filling up to the point that the top of your growth medium is constantly wet. You may need to reduce the fill time, so that the tray doesnt fill up far enough to wet the top of your media, or allow a longer drying out period between cycles to discourage the fungus gnats from moving in.



    Fog the hydroponics room with a fogger containing pyrethrum. Follow all label directions carefully, and only use this product if it is safe for the plants in your garden.

    How Do I Get Rid Of Fungus In Garden Soil

    Getting rid of bad fungus permanently is just about impossible. Some types of fungi survive in soil for years, even when there are no crops for them to feed on. But you can lower the chance of a repeat appearance of garden-wrecking fungia couple of ways.

  • Get rid of the sick plants. Once your garden is infected, you cant save the plants. Dig up the sick ones and throw them in a trash can, not a compost pile, so the fungal disease wont spread.
  • Clean up all garden debris at the end of the season. Cut down the perennials, pull up the annuals, rake up leaves and haul it all out, because fungus can feed on dead plants over the winter.
  • Rotate your crops. Plant crops in different places in your garden then you did last year. Move the tomatoes to the spot where you had marigolds or the herbs to the spot where you had potatoes. If your garden isnt big enough for this, dont plant anything in the garden for a year or two so soil fungus has no host plants to feed on. You can plant in containers for a year so you dont go without fresh veggies, then switch back to the ground garden next year.
  • Plant disease-resistant varieties. Look for veggie and herb varieties that have been bred to resist common soil-borne diseases.
  • Use a fungicide. Apply a fungicide early and often to your garden plants, before they get sick. Because the best defense is a good offense.
  • Organic Treatments For Fungal Infections

    July 6, 2016 by fifthseason

Some of the most common infections are powdery mildew, rust, leaf spot, and blight. Preventative treatments, and acting quickly to treat fungal infections when you first notice them are crucial to keeping your plants healthy and prevent annually recurring infections in trees and perennials. Luckily, myriad organic products exist to prevent and treat fungal infections. We know that the options can sometimes be confusing or seem overwhelming, so heres a helpful primer:

    Sulfur Fungicide

    Products include: Bonide Sulfur Plant Fungicide, Safer Garden Fungicide

    Copper Fungicide

    Oil Based Fungicide

    Neem oil is going to be the most effective oil for controlling fungal infections. It is a good choice for mild to moderate powdery mildew infections, but doesnt do much good for blight, leaf spot, or rust. Oils are mostly used to control insects, but since many fungal infections are spread by insects, keeping pests at bay is a good practice for maintaining plant health.
