Methods and Precautions for Growing Ligustrum
In courtyard greening and potted landscape creation, Ligustrum is highly favored for its evergreen characteristic throughout the year. As a灌木 plant with strong adaptability, key maintenance points need to be mastered to make it show the best growth state. This article systematically sorts out the core skills of home care for Ligustrum, from soil configuration to pest and disease control.
Core Elements of Ligustrum Cultivation
Selection of Soil Matrix
The development level of Ligustrum roots directly affects the plant's growth. It is recommended to use a mixed matrix of decayed leaf soil + coarse sand + garden soil (4:3:3). For potted plants, it is suggested to repot every 2 years, before the new buds sprout in early spring, retaining 1/3 of the protective soil. For ground planting, soil improvement is necessary, and the planting hole should be mixed with 5kg of decomposed sheep manure as a base fertilizer.
Management of Light Intensity
In spring, autumn, and winter, it can be exposed to full sunlight, while in summer, it should avoid strong midday sunlight. For north-facing balconies, it is recommended to supplement 2000-3000lux of light with a plant growth light. During continuous rainy seasons, attention should be paid to ventilation to prevent excessive growth, and the pot should be rotated 45 degrees monthly to maintain a symmetrical plant shape.
Key Steps of Daily Maintenance
Water and Fertilizer Control Plan
During the growing period, maintain soil moisture at 40%-60%, and use the "soak method" for watering to ensure good drainage. From May to September, apply diluted decomposed soybean cake water (1000 times) every 20 days, combined with potassium dihydrogen phosphate foliar fertilizer. Stop fertilizing and control water in winter, keeping the soil slightly dry.
Timing for Shaping Pruning
The best pruning period is before the early spring sprouting, removing crossed and diseased branches and retaining the main shaping branches. After the new shoots in summer have lignified, pinch the tips to maintain a plant height of 1.5-2 meters. After shaping and pruning, apply a wound healing agent promptly, and disinfect pruning tools with 75% alcohol.
Key Points for Pest and Disease Control
From April to June, focus on controlling scale insects by hanging yellow sticky traps and combining with the application of matrine. Before the rainy season, use a 800 times solution of mancozeb to prevent leaf spot disease. Isolate immediately if black soot disease is found, and spray with azoxystrobin plus an organic silicone synergist.
Through scientific maintenance management, Ligustrum can maintain its ornamental value for over 15 years. Regularly observe the plant's condition and adjust the maintenance strategy according to seasonal changes to make this evergreen灌木 a bright presence in home greening. It is recommended to establish a maintenance log, recording watering and fertilizing times, and gradually master a personalized maintenance rhythm.
