Signs of Cold Stress in Scotch broom
Symptoms
Scotch broom tolerates cold well and flourishes optimally when temperatures exceed 60℉. In winter, it needs to stay above 50℉. If temperatures drop below 40℉, while no immediate winter damage might be apparent, branches can become brittle and dry by spring, with no new growth appearing.
Solutions
In spring, remove any dead branches that have not produced new foliage.
Signs of Heat Stress in Scotch broom
Symptoms
During summer, Scotch broom should be maintained below 75℉. When temperatures surpass 85℉, the plant's leaves might lighten in hue, tips could dry and shrivel, and it becomes more prone to sun damage.
Solutions
Remove any sun-damaged and desiccated sections. Relocate the plant to a spot offering protection from intense midday and afternoon sun, or deploy a shade cloth. Water the plant in the morning and evening to maintain soil moisture.
