Herbs are a special group of plants used for flavoring and scents. Many herbs used in flavoring foods and teas (culinary herbs) can be grown in Mississippi gardens. Most herbs should be grown in full sun, but a few tolerate light shade. They prefer a well-drained soil of medium fertility with a pH of 6.0 to 7.0. An organic mulch in summer benefits the plants.
Herbs that can be grown in Mississippi are annuals that are planted every year, biennials that are planted in the fall and flower the following year, hardy perennials that come back year after year, and tender perennials that may survive a mild winter but often need to be treated as annuals or protected from freezing temperatures.
You can start most popular herbs from seeds. Many of the perennial herbs are propagated by stem cutting, layering, or crown divisions. Annual, and some perennial, herb plants are sold at nursery and garden centers, and seeds and plants are offered by many mail-order catalog companies.
Because herbs are used in very small amounts, just a few plants of each type may be enough. If you want a large quantity of a particular herb, such as sweet basil for making pesto, plant the herb in the vegetable garden. Otherwise, prepare a small area especially for herbs so that they can be enjoyed for their appearance as well as fragrance.
Herbs have few pests, which is good because there are few if any pesticides approved for use on these plants. When planting herbs in the vegetable garden, protect them from pesticides used on vegetables.
Grow herbs started from containers so they can be set in the garden without disturbing the roots. Borage and dill are two herbs that do not transplant well if bare-root. Either scatter seeds in the garden where these herbs are to grow, or start plants in containers.
The flavors and scents of herbs are caused by oils in the plant tissue. High fertilization, excess moisture, and shade result in low oil content and weak flavor. The oil content in many herbs is at its highest just before the plants begin to flower.

With the fall season slowly creeping in, there are many things to look forward to, including the drop in temperature. I enjoy watching the leaves change color and drop, too. That also means now is a great time to pull out your rakes, garbage bags, and compost bins and prepare to remove the leaves in your yard! Here are a few other things for you to accomplish in your garden and landscape during the month of September.
When members of the Jackson chapter of Alpha Kappa Alpha sorority brainstormed ways to serve their community, they decided to start a gardening project. Their plan was twofold: grow fresh produce for members of the community who could not get to the grocery store on a regular basis; and get community members involved and teach them how to grow produce. But they soon discovered they were going to need some guidance.
After a relatively mild summer, heat and humidity have arrived in full force in Mississippi. Going outside during the afternoon is miserable these days! If you’re like me, I try to get all my outdoor activities wrapped up in the morning or late afternoon to avoid the heat. Be sure you can recognize the signs of heat-related illness, and remember to drink plenty of water anytime you’re outside! Hydration is important!
