[Basil] Please help me understand what happened here.
First of all, I must explain that I'd never tried to grow any sort of plant before, so I don't really know what I'm doing yet.
I purchased a basil plant from Walmart. It was in a small plastic pot.
I kept the pot in a bowl which contained about an inch of water. After several days had passed, I was pleased to see that it looked healthy.
I noticed that Harris Teeter was also selling live basil plants, but theirs were a little larger and more robust-looking. Another noteworthy difference is that they did not have pots. I purchased two of the HT plants and placed them in the bowl with my other basil plant.
As you can see in the photo, my two newest basil plants have died, while the Walmart basil remains alive.
The instructions on the Harris Teeter basil plants said to put the roots in water, so I thought nothing of setting them in the bowl with 1" of water. Was this my mistake? It hasn't been sunny here, lately, but I thought they would get adequate light at the window I chose. I changed the water every day and did not use any fertilizers on them.
What went wrong? What should I have done?
