Copper is important to citrus trees and vegetables. Deficiency symptoms vary between species and include yellowing of young leaves with green spots at the end of veins. Young leaves can also be curled and spurs stunted. Plants grown with high levels of nitrogen have a higher requirement for copper.

Bluestone is a soluble, quick acting soil amendment.
