Help! I'm losing my new dill plants. There are several herbs in this pot. I bought it two weeks ago. It was completely well, flourishing. I had it inside. Some of the stems nd leaves started turning brown. Thinking it didn't get enough light, I added a lamp of three grow lights. I turn them on in the morning and off at night. It didn't change for a couple of days. Then yesterday it was more brown and limp. I'm afraid it might be gone. What should I do? How do I figure out why it turned brown and limp? Help!
