If you have previous experience in having a worm pit then you would have seen small plants growing up in the pit from the kitchen scrap. They can’t continue to grow as they had to depend only on the worms for food.
When plants grow naturally, they consume the worm castings which are available on the top of the soil, and they will also be available from under the ground. Few plants grow roots deeper to fetch water, and they may reach the worm castings in the deep burrows made by night crawling animals.
Though many people see the garden tower in home improvement shops and ads, they remain a bit hesitant since they have doubt whether they would work or not.
