    It's about the water and soil:


  • If you slide the knife into the soil and it comes out with wet soil, your plant does not need watering.

    This is a similasr concept to the old "toothpick routine" of testing the doneness of a cake or cupcakes. :)

    It could also break up the soil and allow for better growth, but I suspect that the other answers are better.

    Hi! You read the newsletter today! It is the same method you use when baking a cake, or sticking your finger into a potted plant. You are checking for moisture. If the soil is dry about one inch down, the plant needs to be watered. I always stick my finger in to the first joint on my index finger. If I feel dampness, it's good and doesn't need to be watered. Good luck and stay safe!

      That was not was the post was for. It was incorrectly captioned by the Hometalk team as such. It was sticking a plastic knife into the soil to see if the soil was wet or not.

    Hi Diana: Well, for one, it prunes the roots and stimulates new root growth. The slashing of the roots also stops the roots from growing in circles and choking the plant. :)

    Hi Diana, it is used as a gauge for how wet the soil is.

    Many people growing pot do this and it is called splitting stems. It is a method used to increase production by stressing a cannabis plant encourages it to take up more nutrients, which in turn results in more vegetative growth and heavier harvests.
