Yates Liquid Copper and Citrus
My lemon tree appears to suffering leaf curl. Can your Liquid Copper be used to alleviate this problem?
No, Liquid Copper is not registered to treat Leaf Curl in citrus.
Curling leaves in citrus are commonly caused by over-watering or exposure to cold winds, so check the soil moisture around the tree with a bamboo cane. If the soil is wet/clayish, reduce watering frequency until summer arrives, and consider treating the area with a liquid clay-breaker.
