I'm afraid that the general consensus within this forum is that it is very challenging to grow herbs inside. Most of them simply prefer the full sun, for one thing. That is difficult to duplicate even with artificial lighting.

that has unfortunately been my experience so far. Why do I continually read about "growing some herbs in a pot on the windowsill?"

Apartments, mobility issues, it's just something to try, or whatever the reason keep people trying to do it. They may have success for a while but eventually many of the herbs succumb to poor lighting, too much water, and insects. The posts here can back that up.

I am in Zone 6 and even though I have a garden I try to bring some herbs indoors for winter. I have had rosemary, marjoram and lemon grass in containers that I leave outside in late spring and bring back indoors in early fall, for about 4 years now. I also plant garlic cloves for indoor use almost all year round. 5-6 cloves from grocery sotre garlic stuffed in potting mix in a 6-8 inch container will yield fresh garlic chives in 10-15 days.
I used to have Thyme and Lavender too, but those didnt survive beyond two years.

My guess is it is the uneven heating /cooling and drafts that get these plants more than anything else.

Hope this helps.

I've had really good luck with Rosemary, thyme, and oregano grown on my south facing windows...not so much luck with parsley, basil, or sage. I keep them pretty dry (mostly due to neglect?).
