We wanted to see which of three added fertilizers would result in more growth for our basil plants; a commercial powder, our own compost, and our own worm castings, with an a fourth basil plant with nothing added as a control.
Here is the ‘Nothing Added’ plant
The commercial powdered fertilizer.
The worm castings plant.
And above is the added compost one.
Hmm… Can’t tell the difference?
Well I figured out that the problem with my experiment was that as basil plants get bigger, you can’t help but want to make some pesto.
So the photos above are after I cut off the best leaves to use in my pesto. You’ll just have to take my word for it that the one with the added compost wins. All for the advancement of Science!
