Culture methods of blue sage
1, sowing and reproduction: blue sage seeds per gram about 920, generally choose 200 or 288 hole plate to sow, the medium is best imported seedling peat soil and domestic seedling peat soil after disinfection, sowing good need in the surface covered with a thin layer of vermiculite, and then covered with film, the appropriate temperature for seed germination is 20 degrees Celsius, germination days are generally 5 days 8 days.
2. Management of budding stage: the sprouting stage of blue sage will continue to take root and the stems will appear and the cotyledons have expanded. At this time, it is necessary to maintain proper humidity and prevent excessive wetness. Fertilizers are generally used with nitrogen, phosphorus and potassium water-soluble fertilizer at 20:10:20. Then, for a longer period of time, the root will be inserted into the hole in the hole plate and several true leaves will appear. At this time, it is necessary to increase the concentration of fertilizer and control the humidity and temperature. Prevent the seedlings from overgrowing at this stage.
3. Temperature conditions: when the true leaves of blue sage reach 2-3 leaves, you can begin to transplant into potted plants. Generally, 12-13 cm potted plants are selected for transplanting. The substrate needs loose and ventilated garden soil, as well as organic fertilizer and compound fertilizer. The temperature will drop to 18 degrees after entering the garden, and may drop to 15 degrees in a month. It should be noted that if the temperature is below 15 degrees, the leaves will turn yellow or fall off, and above 30 degrees, the plant may stop growing.
4. Rational fertilization: blue sage needs to apply 1500 times diluted ammonium sulfate to change the leaf color during the growing period, and the effect is better. Remember that do not apply urea at low temperature. Continuous fertilization can keep the plant roots strong and branches and leaves luxuriant. I like to grow in places with plenty of sunshine. I usually use compound fertilizer containing calcium and magnesium once a month, and proper shading is needed in hot summer.
5. Pest control: common pests of sage include whitefly, aphids, common diseases such as downy mildew, leaf spot, etc., which need to be actively controlled. Usually, carbendazim or chlorothalonil is sprayed once every 7 to 10 days, and 2000 times to kill or 1000 times dichlorvos to control insects every 10 days.
