Herbs as Houseplants

Posted in: Herbs - Care Info

Grow herbs inside during the winter to have fresh herbs at your fingertips for winter salads, stir fries and sauces.  Plus make your home fragrant during the Holidays with Christmas herbs like,  rosemary, scented geraniums, the mints, lavender and lemon verbena. You can buy seedlings or start with seeds.  If you plan ahead you can transplant them from your outdoor garden.

Follow these easy care for success!

Herbs need sun light:

Most herbs thrive on light – outside herbs require 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.)  When growing herbs indoors, they get a lot less light, especially in the winter, so you'll need to use a grow lamp
at least 12 hours a day.  Hang cool white fixtures 6”-8” above the herbs.  If you have no natural sunlight let the grow light on for 14-16 hours a day.  Your plants will be bushy and productive.

There are many different kinds of grow lights available, including Jump Start Light System,
or Hydrofarm Light System.


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 will die 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!  Since air and soil temperature can affect plant growth rates, keep your seedlings warm with a seedling heat mat, available at your garden center. 

Soil:  Herbs will need nutrients, oxygen and moisture at the root level.  Good drainage is important!  Esbenshades Potting Soil has been very successful in growing herbs. 
Miracle Gro Moisture Control potting mix
is also a good choice.

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.
