Manganese deficiency symptoms are most often seen on maples. Symptoms are yellow leaves with green veins. Most affected are the youngest leaves.
Applying manganese chelates or using trunk implants will suppress the symptoms. Branches sprayed in the spring with a manganese chelate will green up if manganese is the deficient nutrient.
Trunk implants will prevent the symptoms from occurring for more than one year. The tree should be kept healthy through fertilizing and watering so the implant wounds heal as quickly as possible. The disadvantage of this method is the need to drill holes in the trunk, as discussed under iron deficiency.
