How to Grow Sage: The Latest Planting Techniques and Methods Tutorial
Sage is an evergreen small subshrub of the genus Salvia in the mint family (Lamiaceae), with woody stems, grayish-green leaves, and blue to blue-purple flowers. It is native to southern Europe and the Mediterranean coastal regions and has many different uses and benefits. It is often cultivated as a kitchen herb or medicinal herb and has extremely high cultivation value. Let's take a look at sage planting techniques together below!
Sage Growth Habits
Sage prefers a sunny or semi-shaded environment and is relatively cold-hardy, able to tolerate low temperatures of -15°C. It prefers well-drained sandy loam, is relatively fond of fertilizer, has strong drought tolerance, and prefers well-drained slightly alkaline calcareous soil. It grows on hillsides, roadsides, shaded grass clumps, watersides, and under forest shade. In China, it mainly grows in Zhejiang, southern Anhui, Jiangsu, Jiangxi, Hubei, Fujian, Taiwan, China, Guangdong, Guangxi, and other places, and it is also distributed in Japan.
Sage Propagation Techniques
1. Seed propagation: Sage can be sown in spring and early autumn. Before sowing, to improve the germination rate and promote early sprouting, the seeds can first be soaked in warm water at 50°C. When the temperature drops to 30°C, rinse them several times with clean water, then place them under a constant temperature of 25-30°C for germination, or soak them in clean water for 24 hours before sowing. Both direct sowing and seedling transplanting are acceptable. Because sage seeds are small, shallow sowing is advisable. After sowing, cover with a thin layer of soil and water frequently to keep the soil moist.
2. Cutting propagation: Sage cutting propagation usually takes place in May-June, selecting shoot tips that are not too tender, 5-8 cm long, cutting them off below a stem node, removing 2-3 leaves at the base, and inserting them into a seedling bed at a row and plant spacing of 5 cm × 5 cm, at a depth of 2.5-3 cm. Water after insertion and cover with plastic film to retain moisture. After new roots emerge in 20-30 days, transplant at a density of (45-50) cm × (25-30) cm row and plant spacing.
Sage Planting Techniques
1. Transplanting and potting: When sage has 2 to 3 true leaves, begin transplanting into pots. Generally, 12 cm to 13 cm nutrient pots are chosen for transplanting, and the substrate is garden soil with good looseness and aeration plus organic fertilizer and compound fertilizer. For pinching treatment, when the plant grows 4 pairs of true leaves, keep 2 pairs of true leaves and pinch off the rest to promote side branch development.
2. Temperature management: After potting, lower the temperature to 18°C, and after one month it can be reduced to 15°C. If the temperature is below 15°C, the leaves will turn yellow or fall off, and if the temperature is above 30°C, the flowers and leaves will be small and the plant will stop growing.
3. Fertilization management: During the growing period, apply ammonium sulfate diluted 1500 times to sage to change the leaf color, with good results. Do not apply urea at low temperatures. To make the plant's root system robust and the branches and leaves luxuriant, continuous fertilization is very important. Apply a compound fertilizer containing calcium and magnesium at 100 ppm once every half month, and apply phosphorus and potassium fertilizer once more before flowering.
4. Light management: Sage prefers a sunny environment. In hot summers, appropriate shading is needed, and during the seedling stage, light should be increased to prevent leggy growth.
5. Pest and disease control: Common pests of sage include whiteflies, aphids, etc., which need active control. Common diseases include downy mildew, leaf spot, etc. When diseases occur, spray 50% thiophanate-methyl wettable powder diluted 500 times for control.
