If you’ve been using insecticides in your garden to get rid of those pesky bugs, it’s time that you turn to something that’s natural and safer to use. Diatomaceous Earth is the solution. It has many valuable uses that you’ll find interesting and helpful, especially when pertaining to gardening. DE will help you keep all types of bugs and rodents from enjoying what you’ve worked so hard all summer long to grow and eventually harvest. It works to kill insects or deter them to go elsewhere. Here is more on how to use diatomaceous earth properly, and also the many ways that it can assist you in the garden.  

Will Diatomaceous Earth Hurt My Plants?

Maybe you don’t know much about DE and are concerned that it could wind up damaging your plants? That’s a fair question. Diatomaceous earth has been proven to be a non-toxic product that’s safe not only for people and their pets, but also when it comes to plants. It’s safe to use in your garden, and unlike certain insecticides out there, it also won’t affect the consumption of your vegetables and flowers.

How to Use it Safely

Though it only appears to be a fine powder or dust, don’t be deceived. Diatomaceous earth has sharp tiny particles in it that can be hazardous if you accidentally inhale it. Whatever the amount that you accidentally breathe in, it can cause serious irritation to the throat and lungs, so don’t take this warning lightly. Whatever you are planning on using DE for, be sure that you are wearing a mask that is capable of filtering dust, along with a pair of safety goggles just to be safe. You don’t want it ending up in your eyes.  

How Should I Apply It and How Much Do I Use?

You can apply DE by sprinkling the product around your garden plants or directly onto them, but I’d recommend that you use it as a spray mixture. You will want to use a mixture of 2 cups of diatomaceous earth per gallon of water while using a garden sprayer or atomizer to liberally spray your garden and lawn. Just make sure that you agitate the mixture every so often so that the DE doesn’t settle to the bottom. You’ll start noticing results once the product begins to dry.

Ways to Use Diatomaceous Earth in Your Garden 

Diatomaceous earth gets the job done with all types of bugs and critters when applied to your garden. Some of these bugs include caterpillars, beetles, cockroaches, bedbugs, spider mites, earwigs, and snails. These are some of the other ways that DE can help prevent, or fight for you out in your garden: Diatomaceous Earth: What You Need to Know

Aphid Control

Aphids also pose a major threat to the plants and vegetables that are in your garden, and if they are left unchecked, they can devour entire plants quicker than you could possibly imagine. To help save plants from aphid infestation, spray a mixture of water and ED directly onto the plants. Once the mixture is dry, the powder should accomplish what you hoped it would do. Just be sure that if you do use DE in your garden, that you rinse your produce well when you go to bring it inside and before you eat it.   

Tick, Mite, and Flea Prevention 

Diatomaceous earth can even be used for tick, mite, and flea prevention. Many pet owners and farmers simply choose to apply diatomaceous earth directly to the fur of their pets and farm animals, but you can also spray it in your lawn or garden to help keep them at bay. It’s also nice to know that you didn’t have to use chemicals in your lawn. For every gallon of water that you use, you’ll want to add 1 to 4 tablespoons of diatomaceous earth. Don’t hold anything back when you’re spraying your lawn, garden, or shrub areas. 

Helps to Relocate Unwanted Ants 

Discovering an anthill out in your garden only means one thing, they’ve recently discovered their nearest food provider. The average black ant typically only goes after the leaves of a plant and doesn’t necessarily eat from the vegetable portion. But if you have fire ants roaming your yard, that’s a totally different story. You can get these ants to relocate by dusting the ant hills and their surroundings with diatomaceous earth. It shouldn’t take them long to come to the conclusion that they are not welcome.

Keep Slugs Away

Are you noticing a bunch of slug activity out in your garden lately? This may especially be the case if you’re growing cabbage, lettuce, hostas, sunflowers, or marigolds because those are a few of their favorites. All you need to do is sprinkle a bit of diatomaceous earth around your beloved plants and they’ll avoid these areas. 

Discourages Other Garden Visitors 

As a gardener, you may not mind it as much if a cute little bunny rabbit pays your garden a visit every once in a while, but when you have more than one rodent out there feasting, you may be tempted to reach for a shovel or other weapon. 

Diatomaceous earth happens to be extremely absorbent, and when combined with certain essential oils like citrus or peppermint, it works as a natural rodent deterrent. All you need to do is combine the mixture and place it in tiny jars out in your garden. It will work on moles, mice, rats, and yes, rabbits.       

Final Word

Diatomaceous earth can do many wonders, not only for you but also when it comes to your garden. Mixing it in with your potting soil will help improve drainage, along with air circulation for the roots of your plants. Manufacturers know their product best, so be sure to follow the instructions on the label of the packaging so you know how much DE to use. If you’re watering your plants 3 to 4 times a week, you’ll only need to apply diatomaceous earth once every few weeks, but if you live in a region with more rain or higher humidity, you will need to use it a bit more. May God Bless this world, Linda.

      Hi Tom, that’s one of my biggest concerns, for instance, the bees. I’m very careful where I use it. I never spray the plants, or flowers because that’s where the bees and butterflies visit. I have to compare it to the safety of pesticides. I feel better about using DE for getting rid of the insects and bugs that carry diseases. We have to make a choice, I still get bees so I believe I’m okay doing what I do. I hope this helps. Linda

      Hi Sandra, I have seen those beetles that kill everything. At first, you think they are cute ladybugs but a different color, nope. I’m trying to use whatever I can to keep the insects off my garden. I’m just careful to protect the bees and butterflies. Gardening is so fun! Linda
