How do I over-winter my herbs?
The thyme and the sage if sunk in the ground in a protected area should winter over. Maybe you could even leave them in their pots, but putting them directly in the soil in a protected spot would be best and then they are ready to grow in the ground next. year. If you want them in pots again next summer, then try just sinking the plant and pot in the ground. Make sure the rim of the pot (if it is clay) is covered as it will wick the moisture away from the root ball. The rosemary and the basil are a little more difficult as you need to put them in a very sunny window. The basil needs so much sun that many people do not bother to winter it over. The rosemary needs all the sun it can get, too, and if shy on sun may get mildew. Just keep a eye on it and if it gets a little mildew, treat it with powdered sulfur from the garden shop. It is completely safe and non-toxic but helps control mildew. If you decide to bring the thyme and sage in instead of sinking them in the ground, they, too, need all the sun they can get.
