How to Care for Newly Purchased Lilacs
How to nurture the newly acquired lilac seedlings to ensure their survival? As a popular courtyard planting flower, the management during the acclimatization period of lilacs directly affects their subsequent growth. This article will systematically analyze the key points of scientific care for newly purchased lilacs from six dimensions, including environmental regulation and daily management.
Environmental Regulation during Lilac Acclimatization Period
Temperature and Humidity Management
Newly purchased lilacs need to acclimatize in an environment of 22-25°C, with a day-night temperature difference controlled within 5°C. In the northern regions, it is recommended to acclimatize indoors for 2 weeks, using a humidifier to maintain 60% air humidity. In the southern rainy season, attention should be paid to ventilation to prevent mildew.
Light Intensity Adjustment
Keep them in a diffused light environment for the first 3 days, and gradually increase the duration of direct sunlight from the 4th to the 7th day. Use a shading net to control the light intensity between 15000-25000Lux, avoiding strong midday sunlight that may burn the tender leaves.
Standard Daily Management of Lilacs
Root Treatment Techniques
After removing from the pot, cut off the black-brown decayed roots, retaining the white new roots with a diameter greater than 2mm. Soak in a 50% carbendazim solution (800 times diluted) for 20 minutes, then let the roots dry until the cut forms healing tissue before repotting.
Substrate Formula Optimization
Use a mixed substrate of peat soil: perlite: decomposed leaf soil = 5:3:2, adding 50g of bone meal per pot as a base fertilizer. For deep pots, a 5cm layer of ceramsite should be laid at the bottom for drainage.

Water and Fertilizer Management Cycle
During the acclimatization period, maintain a substrate moisture content of 30%-40%, and after recovery, implement an alternate wet-dry method. After flowering, apply phosphorus-potassium fertilizer (N-P-K=5-15-30), and in the late autumn, apply decomposed sheep manure at a rate of 2kg/㎡.
Disease and Pest Control
Apply matrine monthly to prevent aphids, and use mancozeb before the rainy season to prevent leaf spot disease. If borers are found, promptly inject phoxim emulsion.
Through scientific acclimatization management and a systematic care plan, the survival rate of newly purchased lilacs can be increased to over 95%. It is recommended to regularly observe the plant's condition, establish a care log to record growth data, adjust management measures based on regional climate characteristics, and ensure the healthy growth of lilacs with fragrant blooms every year.
