Diatomaceous earth (DE) is currently gaining attention because it solves insect pest problems. Toxicologists and Entomologists have constantly decried the use of insecticides or pesticides because of the harmful effect of their residue on the environment and beneficial insects.

What is Diatomaceous Earth (DE)?

How Does Diatomaceous Earth Work?

Diatomaceous earth might look like a fine powder, but it comprises cylindrical-shaped modules with spikes. These spikes break into the skeleton of the insects and cause injury.

How Does Diatomaceous Earth Work

If you find that insects have infested your potted plant, you can apply the diatomaceous earth to the plant and get rid of the insect pests within few days.

You should apply your DE during morning hours, shortly after the morning dew has dried up. It is important to note that you should only apply the DE when the soil is dry. If you apply it and rain falls, it will wash away all of them.

While diatomaceous earth (food grade) is safe, it is not safe inhaling them. They could cause respiratory discomfort. So, when you are using the DE, use goggles to protect your eyes and masks to cover your nose.

Besides this, apply the DE when the weather is not windy, so the DE does not go onto other plants that are free of insect pests. The DE kills indiscriminately, whether or not the insect is beneficial.

To use diatomaceous earth, pour it into a dust spreader and then spray it on your potting soil. Spray on the foliage and then spray on the inner and outer sides of leaves.

Ensure that you sprayed the leaves, the soil, and the foliage thoroughly with the DE so that the insects do not avoid them and proceed to parts that are not covered with the spray.

It is also a good idea to mix DE with water. It will prevent the DE from going to unwanted places in your garden. Mix a water gallon with two cups of DE and spray. When the water dries, the powder will still be on the plants.

Apart from fighting insect infestation, the diatomaceous earth can also serve other purposes.

1. Improves the Soil of the Potted Plant

When you mix the potting soil with diatomaceous earth, it will improve the texture. Since the DE is absorbent, it will keep moisture in the soil and drain the excess. If the soil becomes too dry, the DE releases water into the potting soil.

This means that the frequency of watering your potted plant reduces. DE is also useful in helping the root of your plant absorb the fertilizer and nutrient you applied.
