A Herb Growing Guide

Herbs are a delightful addition to any garden, offering a variety of flavors, aromas, and medicinal properties.

Whether you’re a seasoned gardener or a beginner, growing herbs can be a rewarding experience.

This guide will explore the differences between annual and perennial herbs, provide a step-by-step guide for growing them, and share tips for using herbs in various ways.

Annual Herbs

Annual herbs complete their life cycle within one growing season.

They grow, flower, produce seeds, and die within the same year.

Common examples include cilantro, dill and basil.

These herbs tend to have fast growth rates and can be sown and harvested multiple times in a single season.

Perennial Herbs

Perennial herbs live for more than two years.

They may die back to the ground during the winter but will regrow from the same root system in the spring.

Examples include rosemary, thyme, and mint.

Perennials often require more time to establish but can provide harvests for many years once established.

1. Planning Your Herb Garden

Choosing the Location:

Sunlight

Most herbs require full sun, which means at least 6-8 hours of direct sunlight per day.

Some herbs, like mint and parsley, can tolerate partial shade.

Soil

Herbs prefer well-drained soil with good organic matter.

Raised beds or containers can be ideal for ensuring proper drainage.

Space

Consider the mature size of the herbs. Some herbs, like mint, can spread aggressively and may require containment.

Selecting Herbs

Decide which herbs you want to grow based on your culinary preferences and gardening goals.

Choose a mix of annual and perennial herbs to ensure a variety of flavors and continuous harvests.

2. Preparing the Soil

Testing

Test the soil pH to ensure it’s within the optimal range for herbs, typically between 6.0 and 7.5.

Amend the soil based on the test results. Add lime to raise pH or sulfur to lower it as needed.

Preparation

Work organic matter, such as compost or well-rotted manure, into the soil to improve fertility and drainage.

For containers, use a high-quality potting mix designed for herbs and vegetables.

3. Planting Herbs

Starting Seeds Indoors

For a head start, begin seeds indoors 6-8 weeks before the last expected frost date

Use seed trays or small pots filled with seed-starting mix

Sow seeds according to the packet instructions, typically at a depth twice the seed’s diameter

Keep the soil moist and place the trays in a warm, bright location or under grow lights

Transplanting & Direct Sowing

Transplant seedlings outdoors after the last frost date when the soil has warmed

Harden off seedlings by gradually exposing them to outdoor conditions over a week

Direct sow seeds of hardy annuals and perennials in the garden once the danger of frost has passed

Spacing & Depth

Follow spacing recommendations on seed packets or plant labels. Plant seedlings at the same depth they were growing in their pots

4. Caring for Your Herbs

Watering

Water regularly, keeping the soil consistently moist but not waterlogged.

Herbs in containers may need more frequent watering than those in the ground.

Mulching

Apply a layer of mulch around herbs to conserve moisture, suppress weeds, and regulate soil temperature.

Fertilizing

Feed herbs with a balanced, organic fertilizer during the growing season.

Avoid over-fertilizing, as this can reduce the intensity of the herbs’ flavors.

Pruning & Harvesting

Regularly prune herbs to encourage bushy growth and prevent flowering, which can cause leaves to become bitter

Harvest leaves in the morning when their essential oils are most concentrated

5. Overwintering Perennial Herbs

In-Ground Perennials:

In colder climates, protect perennial herbs by applying a thick layer of mulch or straw around the base of the plants to insulate the roots.

Container Perennials:

Move potted perennial herbs to a sheltered location, such as a garage or basement, where they won’t be exposed to freezing temperatures.

Reduce watering during the dormant period, but don’t let the soil dry out completely.

Growth Cycle

Maintenance

Harvesting

Culinary

Fresh

Snip fresh herbs like basil, parsley, and cilantro to add vibrant flavor to salads, soups, and sauces.

Add rosemary, thyme, and sage to roasted meats and vegetables for depth of flavor.

Drying

Harvest herbs before they flower for the best flavor.

Hang small bundles of herbs upside down in a dark, well-ventilated area to dry. Store dried herbs in airtight containers away from light and heat.

Freezing

Chop herbs and place them in ice cube trays, then cover with water or olive oil and freeze. Use herb cubes to add fresh flavor to soups, stews, and sauces.

Infusing

Create herb-infused oils and vinegars by placing fresh herbs in bottles and covering them with oil or vinegar. Allow the mixture to sit for several weeks to develop the flavors before using.

Restorative

Teas

Make herbal teas by steeping fresh or dried herbs like mint, chamomile, and lemon balm in hot water.

Herbal teas can aid digestion, promote relaxation, and offer other health benefits.

Tinctures

Extract the medicinal properties of herbs like echinacea, valerian, and ginseng by steeping them in alcohol or glycerin. Tinctures are concentrated and can be used for various health purposes.

Salves & Balms

Infuse oils with healing herbs like calendula, comfrey, and lavender.

Use the infused oils to create salves and balms for skin conditions, cuts, and burns.

Household

Aromatherapy

Use essential oils derived from herbs like lavender, peppermint, and eucalyptus in diffusers to enhance mood and wellbeing.

Create sachets with dried herbs to freshen up drawers and closets.

Cleaning

Make natural cleaning solutions with herbs like thyme, rosemary, and lemon verbena, which have antibacterial properties.

Add herbal extracts to homemade cleaning sprays and disinfectants.

Pest Control

Plant pest-repelling herbs like basil, mint, and marigold in the garden to deter insects.

Use essential oils from these herbs in sprays to protect indoor plants.
