How to grow blue sage? Seedling raising methods and pot cultivation techniques of blue sage

Blue sage is a perennial herb of the genus Salvia of Labiatae, but it is cultivated for more than one year, with terminal verticillum, pink blue or pink purple flowers, flowering from spring to summer, garden used in flower beds, flower borders, from planting, cut flowers, potted flower cultivation, with high ornamental value. Let's take a look at how to grow blue sage.

Growth habits of blue sage

Blue sage likes warm, moist and sunny environment, has strong cold tolerance, and is afraid of heat and dryness. It is suitable to grow in loose, fertile and well-drained sandy soil. The optimum temperature for growth is 18: 23 ℃, flowering at 70-100 days after sowing, soil temperature 20-23 ℃, seed germination days 5-8 days, soil suitable pH 5.5-5.8, it is very important to keep the leaf surface dry and prevent diseases.

Sowing and raising seedlings of blue sage

Blue sage is usually propagated by sowing, which is suitable for sowing in spring and summer, and can also be sowed at any time according to needs. The best substrate is peat and perlite, or rotten leaf soil. The culture soil is screened and placed in the seedling plate, soaked with 500-600-fold carbendazim solution, slightly dried and sowed, about 1000 grains per square meter. After sowing, the seedlings need to be planted for 1 or 2 times, and the seedlings can be planted when the height of the seedlings is 15 cm.

Planting management of blue sage

1. Transplanting into the pot: when the true leaves of blue sage reach 2 to 3 pieces, the pot begins to transplant. Generally, the nutrition bowl of 12 cm to 13 cm is selected for transplanting, and the loose and ventilated garden soil with good ventilation is selected as the substrate plus organic fertilizer and compound fertilizer. When 4 pairs of true leaves were produced in the coring treatment, 2 pairs of true leaves were left to promote lateral branches.

2. Temperature management: the temperature of blue sage dropped to 18 ℃ after potting, and to 15 ℃ after a month. If the temperature is below 15 ℃, the leaves will turn yellow or fall off, and when the temperature is above 30 ℃, the flowers and leaves will be small and the plants will stop growing.

3. Fertilization management: 1500 times diluted ammonium sulfate was applied during the growing period to change the leaf color, and urea was not applied at low temperature. In order to make the plant have strong root system and luxuriant branches and leaves, it is very important to apply fertilizer continuously. The compound fertilizer 100ppm containing calcium and magnesium is applied once a month, and phosphorus and potassium fertilizer is applied once before flowering.

4. Light management: blue sage likes the environment with plenty of sunshine, needs proper shading in hot summer, and strengthens the light to prevent overgrowth in seedling stage.

5. pest control: the common pests of blue sage are whitefly, aphids and so on, which need to be actively controlled. Common diseases are downy mildew, leaf spot and so on. When the disease occurs, it can be sprayed with 50% topiramine wettable powder 500 times to control.

Ecological habits and temperature conditions of blue sage Sage prefers warm, moist and sunny environment, strong cold tolerance, fear of heat and dryness. Under soil conditions, blue sage should grow in loose, fertile and well-drained sandy soil. The cultivation technique of blue sage the planting period refers to about 250-300 seeds per gram, which is suitable for sowing and sowing in spring and summer. Germination soil temperature 20 ℃ 23 Mel germination days: 5 Mel 8 days. The suitable temperature for growth is 18 Mel 23 ℃ sowing to flowering: 70 Mel 100 days. The PH value (pH) is 5.5. The height of the 5. 8 trees is 20. 35 cm. 1ppm is 1/1000000 and 100ppm is 10 kilograms (10000 grams) of water added to 1 gram of fertilizer. The planting period is usually from January to mid-February, and the seeds can be sowed at any time in the greenhouse according to the need. Peat + perlite is the best matrix, and rotten leaf soil can also be used. The culture soil was sifted and placed in a seedling plate, soaked with 500 Mel 600 times carbendazim solution, dried slightly and then sowed, about 1000 tablets per square meter. After sowing, the covering soil is sprayed with liquid medicine to facilitate the close contact between the seeds and the substrate. Cover with film or glass to shade and keep moist. The seedlings emerged in about 5 days. After emergence, the film was gradually removed and the light was gradually enhanced. 1000 times chlorothalonil or tocopherol was used to prevent cataplexy 3 times a week. When the true leaves are 2 pairs, they can be transplanted into a small basin. After a week, the water and fertilizer management is normal. The compound fertilizer solution 150PPM is poured every 10 days (equivalent to 1.5g fertilizer per 10kg of water), and a thin organic fertilizer solution is added each time. The cultivated soil quality is better in fertile loam or sandy loam with good drainage. If the soil is mixed with organic fertilizer before planting, the growth will be better. 3 pairs of true leaves left 1 Mel 2 pairs of true leaves to remove the heart and promote lateral branches. The temperature dropped to 18 ℃ after potting, and reached 15 ℃ in a month. The leaves below 15 ℃ were yellow or deciduous, while those above 30 ℃ were small and stopped growing. In the growing period, ammonium sulfate diluted 1500 times to change the leaf color, the effect is better. Do not apply urea at low temperature. The medium of sowing seedlings is about 920 seeds per gram, and the medium is imported peat soil or sterilized domestic peat soil, and its pH value should be 5.55.8. After sowing, it should be covered with a thin layer of vermiculite and then covered with a thin film. The optimum temperature for germination is 20 ℃ to 23 ℃ and the germination time is 5 to 8 days. In the first stage of germination, the radicle appears and the root begins to form. There is no need to apply fertilizer at this stage, but it is very important to keep the seedling medium moist and need a certain amount of light. Gradually remove the film after emergence. 1000 times chlorothalonil or tocopherol was sprayed 2 to 3 times a week to prevent cataplexy. The second stage of germination continues to take root, the stem appears, and the cotyledons have unfolded. To maintain proper humidity and prevent excessive humidity, water-soluble fertilizer with a ratio of 20-10-20 of nitrogen, phosphorus and potassium can be properly applied. In the third stage of germination, the root can be inserted into the hole of the disk, and several true leaves appear. Increase the concentration of fertilizer, control humidity and temperature, the temperature is reduced to about 20 ℃, need some light to prevent seedlings from overgrowing at this stage. In the fourth stage of germination, the root system clumps, with 2 to 3 pairs of true leaves. Continue to increase the fertilizer concentration, temperature and humidity are the same as the third stage, properly control moisture, strengthen ventilation, still need to prevent overgrowth and prepare for transplanting. When the true leaves of the plant reach 2 to 3 pieces, they begin to transplant into the pot, generally choose a nutrition bowl of 12 cm to 13 cm for transplanting, and choose loose and ventilated garden soil with organic fertilizer and compound fertilizer as the substrate. When 4 pairs of true leaves were produced in the coring treatment, 2 pairs of true leaves were left to promote lateral branches. After the temperature is put into the basin, the temperature is reduced to 18 ℃, and it can be reduced to 15 ℃ in a month. If the temperature is below 15 ℃, the leaves will turn yellow or fall off; when the temperature is above 30 ℃, the flowers and leaves will be small and the plants will stop growing. In the growing period of fertilization, ammonium sulfate diluted 1500 times to change the leaf color, the effect is better. Do not apply urea at low temperature. In order to make the plant have a strong root system and luxuriant branches and leaves, continuous fertilization is very important. 100ppm, a compound fertilizer containing calcium and magnesium, is applied once a month. The light likes the sunny environment, the hot summer needs to carry on the proper shade, the seedling stage strengthens the light to prevent the overgrowth. After sowing, the seedlings need to be planted 1-2 times after sowing. When the seedlings are high 15cm, they are planted in the 10cm basin and coring. Fertilize once every half month during the growing period to keep the basin soil moist. Phosphorus and potassium fertilizer was applied once before flowering, and inflorescence was removed after flowering, and still branches could continue to bloom. The seeds are not consistent in maturity and need to be picked while ripening. It is very important to keep the potted medium slightly dry. Efforts should be made to keep the leaves dry and prevent diseases. In order to make the plant have strong roots and luxuriant branches and leaves, continuous fertilization is very important. 100ppm (N 13-P 2-K 13-Ca 6-mg 3) compound fertilizer containing calcium and magnesium is used once a month. Disease control of blue sage spray 700 times carbendazim or chlorothalonil every 7-10 days. Spray 2000 times the enemy to kill or 1000 times dichlorvos to control insects every 10-15 days. The main varieties of blue sage are Salsa, Flare, Vista, King, Queen, Carabiniere, the distribution area of blue sage steppe is found in southern North America. The garden application of blue sage the pot cultivation of blue sage is suitable for the layout of flower beds, flower borders and garden scenic spots. It can also be dotted with rocks and gaps at the edge of the forest, showing solitude. Put the front of the natural building and the small courtyard, feel more elegant and quiet.
