Signs of Cold Stress in Common lilac
Symptoms
Common lilac tolerates cold well and flourishes when temperatures exceed 60℉. In winter, it needs to stay above 50℉. If temperatures drop below 30℉, while no immediate winter changes might be seen, branches can become brittle and dry in spring, with no new growth appearing.
Solutions
In spring, remove any dead branches that haven't produced new foliage.

Symptoms
In summer, Common lilac should be maintained below 75℉. When temperatures surpass 85℉, the plant's leaves might lighten, tips could dry and shrivel, and it becomes more prone to sun damage.
Solutions
Remove any sun-damaged and dried sections. Relocate the plant to a spot offering protection from midday and afternoon sun, or use a shade covering. Water the plant in the morning and evening to maintain soil moisture.
