Signs of Cold Stress in French lavender
Symptoms
French lavender tolerates cool temperatures moderately well and flourishes optimally when temperatures exceed 65℉. In winter, it needs to be maintained above 60℉. If the temperature drops below 40℉, its leaves might begin to sag. Mild cases allow recovery, but severe instances lead to wilting and eventual leaf drop.
Solutions
Remove any parts damaged by frost. Before subsequent cold exposure, cover the plant with materials like non-woven fabric or cloth, and build a windbreak to shield it from chilly gusts.
Signs of Heat Stress in French lavender
Symptoms
In summer, French lavender should be kept below 75℉. When temperatures surpass 80℉, leaf coloration lightens, leaf tips may dry and shrivel, leaves might curl, and the plant becomes more prone to sunburn.
Solutions
Prune off any sun-scorched and desiccated sections. Relocate the plant to a spot offering protection from the midday and afternoon sun, or use a shade cloth for cover. Water the plant in the morning and evening to maintain soil moisture.
