The Fall Herb Garden

The end of the summer doesn’t mean the end of deliciousness from your garden, not when a fall herb garden can add tantalizing tastes to all your meals. As the season changes, give your herbs a little tender loving care to ensure that they thrive through fall and into winter.

Caring for Perennial Herbs

Perennial herbs that are already established in the garden can easily be winterized, including mint, oregano, thyme, chives, and sage. So long as the herbs are healthy and thriving as summer wanes, they can be prepared for winter. Rosemary lasts well into December and sometimes January outdoors in Ohio. 

First, stop fertilizing herbs in August so they do not continue to produce delicate new growth. Continue to water them adequately, however, as drought stress will make the plants less able to tolerate winter. As their growth slows, trim each plant carefully, using sharp, clean shears for crisp cuts that will minimize strain on the plant. Prune herbs to 4-6 inches in height. It is a good idea to add a layer of mulch to insulate plant roots in colder climates.

Planting Herbs in Autumn

Cool-weather herbs, annual or perennial, can easily be planted in autumn and will be ready to flavor many savory dishes. A container herb garden is an ideal choice for fall herbs since it can be easily moved and protected for the best care. Choose a container with suitable size and depth to nurture the desired herbs, and ensure it has adequate drainage holes to promote good drainage.

Planting several herbs in the same pot will save space and keep them all close by for easy use. You may also consider using smaller pots that can be grouped together in an attractive arrangement. Pots can be positioned right near the kitchen or patio door for easy access, or in a sunny window box.

Protecting Herbs in Winter

Annual herbs or newly planted perennial ones can be at risk if a hard freeze or unexpected storm arrives. Staying alert to weather forecasts and keeping a keen eye on the barometer will help you protect your herb garden as the season deepens. If the temperature is dropping, it is best to shelter your herbs with sturdy covers, cold frames, or cloches. Moving pots or containers temporarily into an insulated garage and near an interior wall that will be warmer can also protect them from cold snaps.

If container herb gardens can safely remain outdoors in the late fall, the pots should be elevated so their drainage holes do not become clogged. Pot feet or plant stands are great options and will help keep the soil from becoming too damp after repeated rains or snows.

Trimming plants into dome shapes is another way to protect the fall herb garden from the onslaught of winter weather. A more compact shape will shed rain and snow more effectively, providing better protection for the plant’s structure and minimizing damage. A dome shape will also be easier to cover if necessary.

Dishes for a Delicious Fall

Fresh herbs add subtle flavors to salads and can be used to season roasts and meats. Infusing soups, sauces, and gravies is another way to create layers of flavor in autumn foods, and herbs can even add unique notes to hot teas, fruit compotes and jellies, or spiced cider. The better you protect your fall herbs, the more you will be able to enjoy them throughout the season and well into winter.
