Transplanting Vs. Direct Sowing

Sage, known scientifically as Salvia officinalis, is a versatile and aromatic herb that is commonly used for culinary purposes as well as in traditional medicine. It is native to the Mediterranean region but can be grown in various climates with proper care. While sage can be purchased as mature plants, many gardeners enjoy starting from scratch by planting sage seeds. By planting sage seeds, you can have control over the growth process and ensure the plant’s health from the very beginning.

When it comes to planting sage seeds, there are two main methods: transplanting and direct sowing. Transplanting involves starting the seeds indoors and then moving the seedlings to a larger pot or outdoor garden bed once they have grown. Direct sowing, on the other hand, involves planting the seeds directly into the final growing location outdoors. Both methods have their advantages and disadvantages, so it is important to consider your specific growing conditions and preferences.

Transplanting sage seeds is a popular choice for several reasons. Firstly, it allows you to have more control over the seedling’s environment, ensuring optimal growing conditions. Additionally, starting seeds indoors gives you a head start, especially in regions with shorter growing seasons. This method also reduces the risk of seeds being eaten by birds or other pests.

To transplant sage seeds, start by filling seed trays or pots with a well-draining potting mix. Moisten the soil gently without soaking it. Place one or two sage seeds on top of the soil in each cell or pot, then cover them with a thin layer of soil. Mist the top layer with water to ensure good seed-to-soil contact. Place the trays or pots in a warm location, such as near a window receiving indirect sunlight, or under grow lights. The seeds should germinate within 1-2 weeks.

When the sage seedlings have developed their second set of true leaves, it is time to transplant them to larger pots or the outdoor garden bed. Carefully remove the seedlings from their original containers, taking care not to disturb the roots. Transplant them into a well-prepared soil bed or individual pots, ensuring they are at the same depth as before. Water the transplants gently but thoroughly. Keep the soil consistently moist, but avoid overwatering, as sage plants are prone to root rot.

Direct sowing, on the other hand, is a convenient option if you have a suitable outdoor growing space or if you prefer a more natural approach. This method is best suited for regions with longer growing seasons and milder climates. Before direct sowing, prepare the soil by removing weeds and loosening it with a rake or garden fork.

To directly sow sage seeds, create shallow furrows in the soil, approximately ¼ inch deep. Space the furrows about 12-18 inches apart to allow ample room for the sage plants to grow. Place the sage seeds in the furrows, spacing them about 6-8 inches apart. Cover the seeds with soil and gently press the soil down to ensure good seed-to-soil contact. Water the area thoroughly after planting.

When To Expect Seedling Growth

Once you have planted your sage seeds, it is essential to know what to expect in terms of germination and seedling growth. Sage seeds typically require a warm and moist environment to germinate successfully. The ideal temperature range for germination is between 60-70°F (15-21°C). The germination process usually takes around 1-2 weeks, though it may take longer in cooler temperatures.

During the germination period, it is crucial to keep the soil consistently moist but not overly saturated. Mist the soil regularly to maintain moisture. If the soil becomes dry, it can hinder germination. Once the seedlings start to emerge, continue to provide them with consistent moisture, allowing the top layer of soil to dry out slightly between waterings.

As the seedlings grow, it is important to provide them with adequate light. Place the seed trays or pots in an area where the seedlings can receive bright but indirect sunlight. If sunlight is limited, supplement it with artificial grow lights. Ensure that the seedlings receive at least 12-14 hours of light per day.

Tips For Successful Sage Seedling Care

To ensure the successful growth and development of sage seedlings, there are several key tips to keep in mind:

1. Watering: Sage plants prefer well-draining soil that is slightly moist. Overwatering can lead to root rot, so it is important to strike a balance. Water the seedlings when the top inch of soil feels dry to the touch. Use a watering can or a spray bottle to deliver water directly to the soil, avoiding wetting the leaves. Aim to keep the soil consistently moist but not waterlogged.

2. Fertilizer: Sage plants generally do not require heavy fertilization. However, you can provide a light dose of balanced fertilizer, such as a compost tea or a diluted liquid fertilizer, once every 4-6 weeks during the growing season. Be cautious not to overdo it, as excessive nutrients can hinder the plant’s flavor and fragrance.

3. Pruning: Pruning sage plants promotes bushier growth and helps maintain their shape. Once the seedlings have developed several sets of true leaves, you can begin pruning by pinching off the top few inches of growth. This encourages the plant to branch out and become thicker. Regularly pinch off any damaged or yellowing leaves to keep the plant healthy.

4. Mulching: Applying a layer of organic mulch around sage plants helps conserve moisture, suppress weeds, and regulate soil temperature. Use materials like straw, wood chips, or compost to create a mulch layer around the base of the plants, taking care not to mound it directly against the stems.

5. Protection: Sage plants are generally hardy, but they can be susceptible to pests such as aphids, spider mites, and snails. Regularly inspect the plants for signs of pest infestation and take appropriate measures to control them. Additionally, provide protection from strong winds, as sage plants can suffer from windburn.

6. Winter care: In regions with harsh winters, sage plants may require some protective measures. Before the first frost, trim the plants back to reduce their height. Apply a layer of mulch around the base to insulate the roots and protect them from freezing temperatures. In extremely cold climates, consider digging up the plants and bringing them indoors to overwinter.

Harvesting And Using Sage

The true reward of planting sage seeds comes when you can harvest and enjoy the aromatic leaves. Sage leaves are at their peak flavor just before the plant flowers, so it is best to harvest them in the morning when the essential oils are most concentrated.

To harvest sage leaves, select healthy and mature leaves from the plant. Using clean pruning shears or scissors, cut the stems just above a leaf node or branching point. Avoid removing more than one-third of the plant’s leaves at a time, as this can stress the plant. Harvesting in small amounts frequently is better than removing a large quantity at once.

Once you have harvested the sage leaves, they can be used fresh or preserved for later use. Fresh sage leaves can be used in cooking, teas, or infused in oils and vinegars for added flavor. To dry sage leaves, bundle several stems together and hang them upside down in a cool, dry place with good air circulation. Once the leaves are completely dry, strip them off the stems and store them in an airtight container away from direct sunlight.


Planting sage seeds is a rewarding and enjoyable experience for any gardener. Whether you choose to transplant the seedlings or directly sow the seeds, sage plants can thrive with the right care and attention. Remember to provide the seeds with optimal growing conditions, be patient throughout the germination process, and follow the tips for successful seedling care. With time, you will be able to harvest your own fresh sage leaves and enjoy the aromatic and flavorful herb in your culinary creations.
