Nutrient monitoring of dusty miller

Dusty miller requires low to medium fertility levels between 100 and 200 ppm N. Insufficient fertility results in lower leaf reddening and stunted plants. Optimal substrate pH values range from 5.5 to 6.2. Substrate pH values above 6.5 inhibit iron uptake, leading to symptoms of interveinal chlorosis (yellowing) and bleaching (white) on the upper leaves.
