Signs of Cold Temperatures in Rue
Symptoms
Rue tolerates cold well and grows optimally when temperatures are above 65℉. In winter, it needs to stay above 50℉. If temperatures drop below 40℉, while no immediate winter changes might be seen, spring may bring reduced or absent sprouting.
Solutions
In spring, remove any sections that have not sprouted.
Signs of High Temperatures in Rue
Symptoms
In summer, Rue should be maintained below 75℉. When temperatures exceed 85℉, the plant's leaves might lighten, curl easily, suffer sunburn, and in severe cases, the whole plant could wilt and dry out.
Solutions
Remove any sun-damaged and desiccated portions. Relocate the plant to a spot shaded from the midday and afternoon sun, or use a shade fabric. Water the plant in the morning and evening to maintain soil moisture.
