cultivation methods of Elsholtzia ciliata
In the family of aromatic plants, Elsholtzia ciliata is deeply favored by growers for its unique medicinal value and ornamental characteristics. This Labiatae plant not only emits a refreshing fragrance but also becomes a common guest in courtyards and balconies due to its adaptability. Mastering the following key maintenance principles will make your Elsholtzia ciliata plants stronger and the flowering period longer.
Three elements of environmental regulation for Elsholtzia ciliata
Golden rule for substrate formula
Cultivation substrate is recommended to use the golden ratio of perlite: humus soil: vermiculite = 3:5:2, which can ensure smooth drainage and continuous fertilization. Note that the substrate pH should be maintained at 6.0-6.8, slightly acidic range, and use diluted white vinegar water to adjust the pH monthly.
Temperature and light协同 management
In spring and summer, maintain the optimal growth temperature of 25-28°C, and during the winter dormancy period, it is necessary to maintain a temperature of 10°C or higher to survive the winter. In terms of light, 6 hours of scattered light per day in spring and autumn, and 30% shading in midsummer to prevent leaf burn.
Water and fertilizer management plan for Elsholtzia ciliata
Smart watering cycle
In the seedling stage, adopt the 'dry and wet' method, water thoroughly when the topsoil 2cm is dry. During the budding stage, implement the '333' watering system: spray the leaves with water morning and evening for 3 consecutive days, and water the substrate thoroughly on the 4th day. Note that water control is required after flowering to prevent fruit drop.
Nutrition supplement strategy
Bury bone meal as a base fertilizer at planting, and apply seaweed fertilizer + EM bacteria solution every 15 days during the growing period. Apply a solution of potassium dihydrogen phosphate (diluted 800 times) before budding, and combine with mature rice washing water irrigation for better results.
Tips for preventing and controlling diseases and pests of Elsholtzia ciliata
Three-dimensional prevention and control of root rot
In addition to the method of wiping roots with liquor, you can prevent in advance by mixing the soil with Trichoderma harzianum. In the early stage of the disease, apply a 1500-fold solution of metalaxyl to the roots, and it will take effect after 3 days of water cutoff and ventilation.
Comprehensive pest control
For the control of small ground bugs (H), it is recommended to combine physical control (manual capture at night) with biological control (release of natural enemies of the lubber grasshopper). Preferably use plant-derived insecticides such as matrine, with a safe interval of 7 days.
From substrate ratio to smart watering, from nutrition management to pest and disease control, this complete Elsholtzia ciliata maintenance system can help growers easily meet the needs of each growth stage. It is recommended to wipe the leaves monthly and rotate the pots regularly to ensure even light exposure, and appropriate pruning can extend the ornamental period of the plant. When you smell the mint-like cool scent in the air, it is the best feedback from Elsholtzia ciliata for careful maintenance.
