A traditional symbol of health and long life! Used in stuffing, and livens up vegetables, potatoes, soups, and stews. This drought-tolerant plant also has edible, purple-blue flowers that attract pollinators, and the gray-green foliage provides an excellent contrast in the garden or containers.
How to Sow
Sage may be grown from seed sown early indoors and transplanted outside after frost, directly sown, or planted as a potted plant.
Sowing Seed Indoors:
- Sow sage seeds indoors 8-10 weeks before the last frost in spring using a seed starting kit
- Sow seeds 1/8 inches deep in seed-starting formula.
- Keep the soil moist at 70 degrees F
- Seedlings emerge in 14-21 days.
- As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow taller. Incandescent bulbs will not work for this process because they will get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
- Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.
- If you are growing in small cells, you may need to transplant the seedlings to 3 or 4 inch pots when seedlings have at least 2 pairs of leaves before transplanting to the garden so they have enough room to develop strong roots.
- Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.
- Sow seeds when all danger of frost has passed in early spring.
- Sow seeds thinly and cover with 1/8 inch of fine soil.
- Firm soil and keep moist.
- Seeds emerge in 14-21 days.
- Thin to 15 inches apart when seedlings have two or three pairs of leaves.
Planting in the Garden:
- Select a location in full sun with rich, well-drained soil.
- Prepare the bed by turning the soil under to a depth of 8 inches. Level with a rake to remove clumps of grass and stones.
- Dig a hole for each plant large enough to amply accommodate the root ball.
- Carefully remove the plant from its pot and gently loosen the root ball with your hands to encourage good root development.
- Set the plants 15 inches apart.
- Place the top of the root ball even with the level of the surrounding soil. Fill with soil to the top of the root ball. Press soil down firmly with your hand.
- Use the plant tag as a location marker.
- Thoroughly water and apply a light mulch layer on top of the soil (1-2 inches) to conserve water and reduce weeds.
- If planting in a container, do not use anything smaller than a 12 inch pot. Be sure to use a commercial potting mix rather than garden soil.
How to Grow
- Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating.
- Mulches also help retain soil moisture and maintain even soil temperatures. For herbs, an organic mulch of aged bark or shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
- Keep plants well-watered during the growing season, especially during dry spells. Plants need about 1 inch of rain per week during the growing season. Use a rain gauge to check to see if you need to add water. It’s best to water with a drip or trickle system that delivers water at low pressure at the soil level. If you water with overhead sprinklers, water early in the day so the foliage has time to dry off before evening, to minimize disease problems. Keep the soil moist but not saturated. Basil should not be allowed to dry out.
- Prune established plants back by one-half to two-thirds in early spring if they are getting too large or leggy.
- Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
Harvest and Preserving Tips
- Harvest short sprigs or a couple leaves at a time as needed. Sage may be used fresh or dried. When used in cooking it is usually used dried.
- To dry leaves, cut whole stems on a sunny morning. Tie stems loosely in small bunches and hang in a dry, airy location out of the sun. OR spread on a cheesecloth or a window screen in a dry, shady location. OR dry herbs in the oven for 2-3 hours on a cookie sheet at the lowest heat, leaving the oven door open. OR use a dehydrator following the manufacturer’s instructions. Crush thoroughly dried leaves before storing. Store in a tightly sealed container in a dry, dark location such as a cupboard.
- Sage may frozen chopped and in ice cubes.
- Sage may also be made into sage butter or infused in honey. It makes a great vinegar as well.
