Keeping herbs alive in containers?
I am hoping some of you can share the secret to successfully growing herbs in containers. I have been attempting this since last spring, but so far have not had much luck.
I've tried starting from seeds and starting from plants. I've tried starting my seeds in different types of containers. I've tried watering more/watering less. I've tried keeping the containers outside (in summer) and inside. Planting in different size pots. Nothing works.
I never have a problem with the seeds germinating. That always happens. However, they seem to grow for a couple of weeks and then, just when they're starting to look like a plant, they die. It doesn't seem to make a difference what type of container (peat pot, styrofoam cup, egg carton, small flower pot) I start them in.
If I start from plants instead of seeds, they still die after about a month. I'm trying to grow basil, thyme, oregano, dill, chives, rosemary, parsley, spearmint, peppermint, sage, dill, and cilantro. Only basil seems to grow with any success. My thyme and mint plants aren't dead but they are sad and sparse, with tiny leaves--not big enough to use for cooking.
Any suggestions on what I'm doing wrong? I live in an apartment with a south-facing window and a south-facing balcony, so they're getting plenty of light.
