A gardening experiment

We’re experimenting with our basil this year. We eat a lot of pesto, and it usually costs something like $6 for a four ounce jar, so we’ve been growing our own. Homemade pesto is very inexpensive and any excess can be frozen too.

Basil tends to grow like a weed here, but I noticed that our plants have not been doing well so far this year. We have them in old kitty litter bins, to keep the dog from trampling them. It’s possible that the potting soil-dirt mix may just be played out, it’s been in the same bins for a few years now. So we’ve added some supplements to the bins to see which one helps the plants the most.

In this bin we have added some compost from our own compost bin. Decomposed fruit and vegetable peels and cores, grass clippings, leaves.

A commercial plant food. It’s a powder that is mixed with water.

Worm castings. We have a worm bin. C likes to say that he takes care of a thousand pets in addition to the dog. Possibly another post to come on that. The worms eat the same type of fruit and vegetable scraps that we have in the compost, they also eat paper, newspaper, and cardboard. We then gather up the finished castings.

And as a control, a bin with nothing added.

Each bin had about a quart of each supplement added to try to make sure each one is equal. Each one also receives about the same amount when we water them.

We’ll see what happens.

  1. As you have noted the soil will be devoid of nutrients after several years of use. You’d have to use a few plants/bins for each regime to run a proper controlled experiment.

    • There’s a lot of other things we could do too like trying to keep track of what goes into the compost. My wife has it all planned out. She’s a research scientist in Immunology, so she knows all about how to set up an experiment correctly. she’s always telling me to make sure to give them as equal water as possible. This is not really very scientifically accurate but we’ll see what happens.
