Summer Savory

Summer savory is an annual herb that is part of the mint family. It’s sometimes used as a substitute, or in conjunction with rosemary, thyme, or sage. With a peppery flavoring, it’s less bitter than its winter savory relative.

The herb is a low-growing shrub with narrow green leaves. During the summer, flowers appear on the plant which can be white, lilac, or pink. Because summer savory is a fast-growing annual plant, it only grows through the summer months. Plant summer savory seeds in the spring.

When to Plant?

This will be determined by your planting zone. There is a final frost date for each area. As a result, you can plan your gardening activities around this date. Check our Frost Dates Across North America: First & Last Frost Dates Chart. However, the date will not be the same for every plant.

How to Plant

Sow seed indoors as early as 6 to 8 weeks before the last frost. Seeds can take 14 days or longer to germinate. Summer savory prefers a rich, well-drained organic soil.


Choose from either clay or plastic pots based on your personal preference.
If growing a single plant, a 6″ deep and wide pot is sufficient.


Three plants can be grown together in a 12″ deep and wide container.
Plant seeds 3 to 5 inches apart and about 1/8 of an inch down in the soil.

Bright, spicy, and slightly sweet, savory has been known for ages in European cuisines, notably in France and Bulgaria. Used for millennia as a seasoning, it also has powerful medicinal properties. Native to the eastern Mediterranean and the Caucasus, savory is a highly aromatic herb. It features a hot, peppery flavor with notes of thyme, mint, and marjoram. Companions: Grow summer savory with beans, onions, garlic, and tomatoes.

How To Cultivate

Soil – Summer savory grows best in well-drained, sandy soil, pH 6.3 – 7.5. Add compost to the soil before planting for nutrients. Mulch lightly to help the soil retain moisture.

Sun – Prefers full sun.

Spacing – 10 – 12 inches apart.

Water-Water regularly to keep the soil moist, not soggy. Be cautious with watering but ensure the soil is never dry. Regular watering is essential, especially in dry conditions.

Fertilizer – Generally not need

ed if planted in compost-rich soil.

If necessary, use a light application of balanced organic fertilizer mid-season.

How To Harvest

Summer Savory can be harvested when it reaches about 6 – 8 inches tall. Harvest by cutting the tips of branches to encourage fuller growth. Harvest frequently, but do not remove more than one-third of the plant at once. Collect leaves before the plant flowers for the best flavor.

Snip off the top leaves and shoots; this will allow the plant to become bushier. Fresh leaves can be stored by placing them in water in the refrigerator or drying them for long-term use.

Hydroponics

Germination: Soak the Summer savory seeds in water for about 24 hours to help with the germination process. After soaking, transfer the seeds to a germination medium, such as a seedling tray or a rockwool cube. Keep the germination medium moist, but not overly wet. Place the tray or cube in a warm and dark location for 2-3 days until the seeds germinate and develop into seedlings. Once the seedlings have grown to a sufficient size, transfer them to the hydroponic system.

pH range: Summer savory grows best in a pH range between 6.0 and 7.0. Regular monitoring of the pH level of the nutrient solution is essential to ensure healthy growth.

EC: The ideal electrical conductivity (EC) level for Summer savory is between 1.2 and 2.2 mS/cm. This can be measured using a handheld EC meter and adjusted as needed.

PPM: The recommended parts per million (PPM) range for growing Summer savory is between 800 and 1600. This can be measured using a TDS/PPM meter and adjusted as needed.

Humidity: Summer savory prefers a humidity level between 40% and 60%. Humidity can be maintained by using a humidifier or dehumidifier, depending on the ambient humidity level in the growing area.

Light hours: Summer savory requires around 12-14 hours of light per day for optimal growth. Supplemental grow lights may be required if natural light is insufficient.

Temperature air: The ideal air temperature range for growing Summer savory is between 68°F and 78°F (20°C to 25°C). Temperatures above 85°F (29°C) can negatively affect the plant’s growth.

Temperature water: The water temperature range for growing Summer savory hydroponically is between 65°F and 75°F (18°C to 24°C). It is essential to monitor the water temperature regularly and adjust it as needed to maintain optimal growing conditions.

Overall, growing Summer savory hydroponically can be a simple and rewarding process. By following these guidelines and monitoring the plant’s nutrient levels and environmental conditions, you can produce healthy and flavorful Summer savory plants.
