Summer savory is an annual culinary herb in the mint family, grown for its peppery, thyme-like leaves. It pairs with beans, lentils, and grilled meats, and is a core ingredient in herbes de Provence. Gardeners value it as a fast, low-maintenance herb that produces usable leaves within two months of sowing.
It is frost-sensitive, so sow after the last frost once soil has warmed. Plants are upright and somewhat sprawling; pinching the growing tips early encourages branching and delays flowering. Harvest leaves before and during bloom for the strongest flavor. It self-seeds readily if flowers are left to mature.
Powdery mildew
White or grey powdery coating on leaves — usually starting on older growth in humid conditions or when nights cool.
Improve air circulation by thinning plants. Apply neem oil or potassium bicarbonate spray at first sign. Avoid overhead watering.
Damping Off
Seedlings collapse at the soil line with thin, water-soaked stems; seeds may fail to emerge or rot before sprouting.
Sow in well-draining mix, avoid overwatering, and ensure good airflow. Remove affected seedlings and let the surface dry between waterings.
Root rot
Plants wilt, yellow, and stunt even in moist soil; lower stems and roots turn brown, soft, and mushy and the plant may collapse. Most common in heavy, wet, or poorly drained ground.
Improve drainage and stop overwatering, and never plant too deep. Lift and destroy badly affected plants along with the soil around the roots. Grow in raised or free-draining beds to prevent it returning.
Aphids
Aphididae →Clusters of small soft insects on new growth and flower buds.
Knock off with a strong jet of water. Ladybirds and lacewings are natural predators. Insecticidal soap as last resort.
