Before treatment, surfaces must be cleaned of dirt, dust, moss, lichens, and other loose materials. For tree trunks and branches, it is recommended to mechanically remove loose bark to ensure even application of the solution. Wooden structures, brick, and concrete surfaces must be dry and mechanically stable. The working solution should be prepared immediately before use by diluting the concentrate with water according to the intended application.
For the treatment of fruit trees and shrubs, use a 1:10 dilution (1 L concentrate per 10 L of water). Apply in early spring before bud break or in late autumn after leaf fall. Consumption: 2–5 liters of working solution per tree, 1–1.5 liters per shrub.
For supplementary iron supply to plants and to reduce symptoms of chlorosis, use a 0.5–1% solution (125–250 ml per 10 L of water). Apply during the growing season, in the morning or evening, avoiding direct sunlight, 2–3 times per season at 10–14 day intervals. For soil treatment, use 250–300 ml of concentrate per 10 L of water, applying 2–3 liters of working solution per 1 m². The product is also suitable for the care and maintenance of wood, brick, and concrete surfaces.
