Step by Step Guide to Use Activated Charcoal for Plants

What you will need:

  • Activated charcoal
  • Tiller
  • Sprinkler
  • General-Purpose Fertilizer (Optional)
  • Measuring Tape

Step 1

Using a measuring tape, take the dimension and calculate the area of the planting site. Do make sure that the quantity of activated charcoal is proportional to the area of the garden. One pound of activated charcoal is sufficient for about two square feet of garden area.

Step 2

Make sure that the garden soil is not wet and dry enough for tilling (not overly dry and dusty). Pick up a handful of garden soil and squeeze it to make a ball of it. If the ball crumbles when you poke it, it can be tilled. If not, wait for the garden soil to turn dry enough for tilling.

Step 3

Using a tiller, like a rototiller, till the garden bed down to a depth of 8-10 inches. Remove roots, rocks, or any other such debris that you might find in your way.

Step 4

As mentioned in the first step, spread the charcoal on the tilled garden bed as per the area. Work the soil so that the charcoal embeds well to a depth of 6-8 inches. You can also add some amount of aged manure to the topsoil for added benefits.

Step 5

The next step is to water the soil thoroughly. You can also add fertilizer to the soil before watering. As the soil now contains activated charcoal, it will absorb both water and fertilizer much more effectively.

Step 6

Leave the site undisturbed for a couple of days till the soil becomes dry to the extent that it is workable. Your garden is now ready for planting.

Note: 

Choosing the right charcoal is one of the crucial steps in this process. Do not use the charcoal from the barbecue, as it contains chemicals and other lighter fluids, which can do more harm than good. The ash of this charcoal is also not suitable for the garden soil.
