Jacks Prof Petunia FeED 20-3-19 25Lb — Single Unit

Jack's Professional® 20-3-19 Petunia FeED Plus Mg Fertilizer is designed for iron-demanding crops such as petunia, calibrachoa, and bacopa. A specialized blend of EDTA, DTPA, and EDDHA iron chelates maintains iron availability across a broad pH range throughout the crop cycle, helping prevent chlorosis and support rich green foliage. Low phosphorus helps limit excessive stretch, while added magnesium supports healthy growth. Not recommended for geraniums or other iron-sensitive crops.
