Zinc Sulfate Monohydrate Powder from The Soil Makers delivers essential zinc for plant health with precise composition: 35.5% zinc (Zn) and 17% sulfur (S), with 35.5% of the zinc being water-soluble for rapid uptake.
Designed for foliar sprays, this zinc sulfate powder helps correct zinc deficiencies in lawn and garden crops, including vegetables, ornamentals, and fruit trees. For tree crops, apply in fall to support overwintering and early spring growth. Because zinc sulfate can cause leaf burn or fruit markings if misapplied, apply per label directions and perform a small test before broader spraying.
- Key specs: 35.5% Zn; 17% S; 35.5% water-soluble zinc.
- Form and use: soluble powder intended for dilute foliar sprays; compatible with standard garden sprayers.
- Safety: harmful if ingested; may cause severe eye damage; highly toxic to aquatic life with long-lasting effects. Handle with care; wear eye/skin protection and prevent runoff.
- Brand value: The Soil Makers combines soil-first science with practical garden performance—trusted by home gardeners and small-scale growers.
