Let's look at your second point first.
Western light, particularly during the winter, is not the best for plant growth. I would consider using supplemental lighting. Just get a two-bulb shop light, and use cold-white bulbs. Hang the fixture so it's adjustible (lightweight chains are the usual choice), and keep it just a few inches above the growing plants.
As to watering. Rosemary is a semi-arid type plant, and does not require a lot of watering. Similar herbs are sage and lavender. For those you can let the soil pretty much dry out before adding more water.
For your others, let the surface dry out before watering and you should be ok.
BTW, to promote leaf growth (which is what you want with herbs), use fish emulsion or other nitrogen-high fertilizer.
Good luck. |
