Activated Charcoal For Gardening: Why The Hype?

When you start mixing activated charcoal in your planting soil, the improvements you’ll see will speak for themselves! Here are some reasons why you should start using it:

Improved Drainage

Activated charcoal is burned at a high temperature making it porous. When added to soil, it improves drainage. 

If you’re planting in containers, you can add granular activated charcoal as one of the bottom layers, and if you’re working the soil of your gardening beds, you can mix powdered charcoal into it. 

Overwatering is one of the primary causes of bacteria, fungus, and rot. Having activated charcoal in your soil will help get rid of excess water and save your plants.

Improved Air Circulation

Just like leaves need fresh air to breathe, plant roots need it at their roots too. When soil becomes more porous, its ability to circulate air improves. Proper air circulation in the soil prevents humidity and moisture, leading to bacteria and mold. 

Improves Soil Fertility

If you use activated charcoal and fertilizer, your soil will remain fertile for longer. 

Activated charcoal absorbs the fertilizer in your soil and slowly releases it over time. This saves your plants from being over-fertilized, which can cause chemical burns, stunted growth, and ultimately the death of your plants. 

Neutralizes Soil

Activated charcoal is a neutralizing agent and balances the acidic levels in the soil.

Another benefit of activated charcoal is that it will stay in your soil for years, so you don’t have to use it frequently. You can top your levels up every few planting seasons.

Activated charcoal isn’t difficult to source, and you can buy it from nurseries, agro vets, pharmacies, online trade sites, and even herb shops.

Reading reviews from other gardeners is also a must when searching for a reputable seller. There’s no better place to find out what works best than from other gardeners in your area!

You can also make your own charcoal to mix into your soil if you’re keen. Here’s how:

  1. Burn wood in a large metal pot.

  4. Add some water and calcium chloride to the powder.

How To Use Activated Charcoal In Your Garden

Activated charcoal can help you create a healthy garden! There are many ways you can use it, and below I list some of my favorites!

Soil Conditioner

The most straightforward way to use charcoal is as a soil conditioner. It has a high potassium content, which helps bring the pH in your soil to an optimal level. 

When you add charcoal to your soil in its powdered forms, it moisturizes the ground and helps create better airflow. 

Pesticide Removal

Activated charcoal has powerful absorption qualities, which makes it perfect for neutralizing the effects of pesticides. A gallon of water mixed with one ounce of charcoal can remove pesticide build-up in a 100 square foot radius. 

You can spray your mixture over any area where organic pesticides were used.
