Dill (partial shade)
Tarragon (partial shade)
- Herbs in shaded areas may grow lanky. Pinch the tops often to encourage bushiness.
- Overfertilizing will result in less flavorful herbs, so use fertilizer sparingly.
- Use new leaves for cooking. Older, larger leaves are more bitter.
- Areas with partial shade in the afternoon can also extend the growing season for some cool season herbs that are prone to bolting during higher heat, such as cilantro.
- The amount of shade may vary by the seasons when the angle of the sun is different. Study your land carefully and see if sunlight is a bigger or smaller problem than you may have thought later in the season.
- Bright and light surfaces nearby (such as white fences or walls) can increase the amount of light that herbs get.
- Morning shade and afternoon shade differ in their effects on garden plants. Some cool season herbs may actually prefer lots of morning sun and then shade during the hot summer afternoons.
- Pay attention to air circulation. Walls and branches can block air flow, allowing moisture to build up and encourage some diseases. Plant herbs with more space between them in shady areas, and be careful to water around the root area and not soak leaves from above.
- It’s even more important to keep weeds at bay for herbs that are already competing for light, water and nutrients in less ideal conditions.
- Pruning nearby trees and bushes can dramatically help increase sun exposure.
- Light is more important in northern states, where we have shorter growing seasons and cooler temperatures. A southern zone 9 garden can tolerate much more shade than a zone 4 garden in Minnesota.
I’ll be posting more about many of these herbs in upcoming posts.
