Signs of Cold Stress in Oakleaf hydrangea
Symptoms
Oakleaf hydrangea tolerates cold well and flourishes when temperatures are above 60℉. In winter, it needs to stay above 50℉. If temperatures drop below 40℉, while winter changes might not be obvious, branches can become brittle and dry by spring, preventing new growth.
Solutions
In spring, remove any dead branches that haven't produced new foliage.
Signs of Heat Stress in Oakleaf hydrangea
Symptoms
In summer, Oakleaf hydrangea should be maintained below 75℉. When temperatures go above 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 the midday and afternoon sun, or use a shade fabric for cover. Water the plant in the morning and evening to maintain soil moisture.
