Herbs as Houseplants
By Esbenshade's Garden Center
Light: Most herbs thrive on light – 5 hours of direct sunlight a day. A southern exposure is ideal!
Exceptions: Mints, bay, parsley, rosemary and thyme, which take partial shade and lemon balm, which actually likes full shade.
No natural sunlight? Use two tube cool white fixtures hung 6”-8” above the herbs, left on for 14-16 hours a day. Your plants will be bushy and productive.
TEMPERATURES: Most herbs prefer temperatures on the cool side, with days 65 degrees and nights 55-60 degrees F. They will do fine with days of 70 degrees F. and nights in the 60’s. Many herbs will survive temperatures in the mid-to-low 40’s, though scented geraniums and basils CAN’T take it below 50 degrees F.
Remember! Herb foliage pressed against frozen windows will freeze and die. Slip a piece of paper between the foliage and the window.
Air Circulation: Herbs don’t like stagnant air; so keep air moving by cracking a window in an adjoining room. A blast of cold air is a CURSE!
Soil: Good drainage is important! Esbenshades Potting Soil has been very successful in growing herbs.
Plant in 4”-6” pots. For plants with spreading underground runners, like the mints, wide shallow pots are ideal. For parsley, a deep pot is better.
Fertilization: Fertilize once a month at half the recommended strength. This schedule is enough to keep them productive, but not so much that they get leggy and lose their flavor.
