Blue Sage Planting Methods and Detailed Seedling and Container Cultivation Techniques
Blue sage (Salvia farinacea) is a perennial herbaceous plant of the genus Salvia in the Lamiaceae family, but it is mostly grown as an annual. Its verticillaster inflorescences are terminal, with flowers in powder blue or powder purple, blooming from spring to summer. In landscaping it is used for flower beds, flower borders, mass planting, cut flowers and potted flowers, and it has high ornamental value. Let us take a look at how to grow blue sage!
Blue Sage Growing Habits
Blue sage prefers a warm, humid environment with plenty of sunlight. It is highly cold-tolerant but dislikes heat and dryness. It grows best in loose, fertile, well-drained sandy loam. The optimum growing temperature is 18-23°C, and it flowers 70-100 days after sowing. The soil temperature for germination is 20-23°C, germination takes 5-8 days, and the suitable soil pH is 5.5-5.8. Keeping the soil slightly dry is very important; try to keep the leaf surface dry to prevent disease.
Blue Sage Sowing and Seedling Raising
Blue sage is usually propagated by sowing, suitable for spring and summer sowing, and it can also be sown at any time as needed. The best substrate is peat and perlite, or leaf mold can be used. Sieve the growing medium and place it in a seedling tray, soak it thoroughly with a 500-600 times dilution of carbendazim solution, and broadcast the seeds after it dries slightly, at about 1000 seeds per square meter. After sowing, thinning is needed 1-2 times, and the seedlings can be transplanted when they reach 15 cm in height.
Blue Sage Planting Management
1. Transplanting into pots: When blue 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. Pinching treatment: when the plant grows 4 pairs of true leaves, keep 2 pairs of true leaves and pinch off the rest to encourage side branches.
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; 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 change leaf color, with good results. Do not apply urea at low temperatures. To make the root system strong and the branches and leaves lush, continuous fertilization is very important. Apply a compound fertilizer containing calcium and magnesium at 100 ppm once every half month, and add phosphorus and potassium fertilizer once before flowering.
4. Light management: Blue sage prefers a sunny environment. In hot summers, appropriate shading is needed, and during the seedling stage, strengthen light to prevent leggy growth.
5. Pest and disease control: Common pests of blue sage include whiteflies and aphids, which need active control. Common diseases include downy mildew and leaf spot. When disease occurs, spray a 50% thiophanate wettable powder 500 times dilution for control.

1 ppm is one part per million; 100 ppm means adding 1 gram of fertilizer to 10 kg (10000 grams) of water.
Cultivation Period
Generally sown from early to mid-January, and in greenhouses it can be sown at any time as needed. The best substrate is peat + perlite, or leaf mold can be used.
Sieve the growing medium and place it in a seedling tray, soak it thoroughly with a 500-600 times dilution of carbendazim solution, and broadcast the seeds after it dries slightly, at about 1000 seeds per square meter. After sowing, cover with soil and then spray the solution again to help the seeds make close contact with the substrate. Cover with plastic film or glass, provide shade, and keep moist. Seedlings emerge in about 5 days. After emergence, gradually remove the film and gradually increase light. Use a 1000 times dilution of chlorothalonil or thiophanate-methyl once a week to prevent damping-off, for 2-3 consecutive times. When there are 2 pairs of true leaves, they can be transplanted into small pots. After one week, carry out normal water and fertilizer management, watering with a compound fertilizer solution at 150 PPM once every 7-10 days (equivalent to 1.5 grams of fertilizer in 10 kg of water), and add diluted organic fertilizer solution with each watering. The growing soil is best as well-drained fertile loam or sandy loam.
If the soil is mixed with organic fertilizer before planting, growth will be even better. When there are 3 pairs of true leaves, keep 1-2 pairs of true leaves and pinch off the rest to encourage side branches. After potting, lower the temperature to 18°C, and after one month it can be reduced to 15°C. Below 15°C the leaves turn yellow or fall off; above 30°C the flowers and leaves become small and growth stops. During the growing period, apply ammonium sulfate diluted 1500 times to change leaf color, with good results. Do not apply urea at low temperatures.
Mid-term
Sowing and seedling raising: each gram contains about 920 seeds. Generally, 200-cell or 288-cell trays are chosen for sowing. The medium is generally imported seedling peat or sterilized domestic seedling peat, with a pH of 5.5 to 5.8. After sowing, cover with a thin layer of vermiculite, then cover with plastic film. The optimum germination temperature is 20°C to 23°C, and germination takes 5 to 8 days.
Germination stage 1: The radicle appears and roots begin to form. No fertilization is needed at this stage, but keeping the seedling medium moist is very important, and a certain amount of light is needed. After emergence, gradually remove the film.
Use a 1000 times dilution of chlorothalonil or thiophanate-methyl once a week to prevent damping-off, spraying 2 to 3 consecutive times. Germination stage 2: Roots continue to grow, stems appear, and cotyledons have unfolded. Maintain appropriate humidity, prevent excessive moisture, and appropriately apply a water-soluble fertilizer with an N-P-K ratio of 20-10-20. Germination stage 3: Roots can penetrate into the cells of the tray, and several true leaves appear. Increase fertilizer concentration, control humidity and temperature, lower the temperature to about 20°C, and provide a certain amount of light to prevent leggy growth of seedlings at this stage. Germination stage 4: The root system forms a mass, with 2 to 3 pairs of true leaves. Continue to increase fertilizer concentration; temperature and humidity are the same as in stage 3; appropriately control moisture, strengthen ventilation, and still prevent leggy growth to prepare for transplanting.
When the plant 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. Pinching treatment: when the plant grows 4 pairs of true leaves, keep 2 pairs of true leaves and pinch off the rest to encourage side branches. Temperature: 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; if the temperature is above 30°C, the flowers and leaves will be small and the plant will stop growing.
Fertilization: During the growing period, apply ammonium sulfate diluted 1500 times to change leaf color, with good results. Do not apply urea at low temperatures. To make the root system strong and the branches and leaves lush, continuous fertilization is very important. Apply a compound fertilizer containing calcium and magnesium at 100 ppm once every half month. Light: It prefers a sunny environment. In hot summers, appropriate shading is needed, and during the seedling stage, strengthen light to prevent leggy growth.
After Sowing
After sowing, thinning is needed 1-2 times. When the seedlings are 15 cm tall, transplant them into 10 cm pots and pinch them. During the growing period, fertilize once every half month and keep the potting soil moist. Add phosphorus and potassium fertilizer once before flowering; after flowering, remove the inflorescences and the plant can still send out branches and continue to bloom. Seeds do not mature uniformly, so they need to be harvested as they ripen.
Potting Medium
Keeping the potting medium slightly dry is very important; try to keep the leaf surface dry to prevent disease. To make the root system strong and the branches and leaves lush, continuous fertilization is very important. Use a compound fertilizer containing calcium and magnesium at 100 ppm (nitrogen 13 - phosphorus 2 - potassium 13 - calcium 6 - magnesium 3) once every half month.
Disease Control of Blue Sage
Spray a 700 times dilution of carbendazim or chlorothalonil fungicide once every 7-10 days. Spray a 2000 times dilution of deltamethrin or a 1000 times dilution of dichlorvos once every 10-15 days for pest control.
