For gardeners who like to cook, there's nothing like fresh herbs. But when the growing season ends, does it mean you have to resort to grocery store herbs?
Thankfully no! By bringing a few herbs indoors, you can continue to enjoy a year-round, flavourful bounty.
Here's how to do it:
The best time to pot up most herbs is before the first frost. Start by selecting the healthiest looking plants to bring indoors. Then dig them up--gently now--causing as little root damage as possible. Divide the plants if necessary. Some perennial herbs that make the transition to indoor conditions fairly easily include chives, garlic chives, thyme, mint, winter savory, and lavender.
Pot the herbs up in fresh, commercial potting soil and water them well. Don't skimp on soil quality. Herbs in pots need a reasonably rich soil mix with good drainage. Here's an all-purpose soil recipe for herbs:
One part potting soil, one part sand, and one part peat moss.
Before bringing plants indoors, double and triple-check each plant for pests by inspecting the stems and leaves. Pests can be sneaky so check under the leaves as well.
Surviving the great indoors
The indoor environment can be quite a shock to plants that are accustomed to cool nights, breezes, rain, and direct sunlight. To help with the transition, you need to reverse the "hardening off" process. Begin by setting the plants out of direct sun for about a week. This gets them used to the lower light conditions indoors. After a few days, bring the plants inside for a few hours, then return them outside. Repeat this "in and out" routine for 5 to 7 days, then bring them indoors for good. This process will make a big difference in how well the survive the great indoors.
Once inside, isolate your herbs (and that means quarantined!) for a couple of weeks before introducing them to the rest of your houseplants. There's nothing worse than causing an infestation caused by overlooking a bug or two.
When it comes to light, herbs need at least 6 hours of direct sunlight each day. (Exceptions are parsley, rosemary, thyme, and mint, which can tolerate partial shade). Supplement with flourescent lighting if necessary. A simple, inexpensive shop-light arrangement works just fine. Hang the lights about 6 inches above the plants and give them 14 to 16 hours of light each day. Turn the plants, especially if they're on the windowsill, so they enjoy even lighting conditions.
