Not to be deterred, on my way home from the gym yesterday I stopped at the Grand Street Gardens and bought some more herbs. I bought some silver thyme and Mexican oregano, they didn't have any rosemary and the oregano plant actually has a couple of nice little flowers.
After looking at the picture I posted yesterday my mom said I most likely over watered the plants. My mom is quite the gardener so I'll take her word for it and wait until the soil is quite dry before watering. I'm just hoping my sole surviving sage plant lives.
