Veins remain a bright green to contrast with the yellow open leaf areas. The leaf edges or the entire leaf will turn brown if conditions worsen. The plant grows slowly and eventually dies if the problem is not corrected. Highly alkaline soils, overwatering or poor drainage induce iron deficiency. Correct overwatering, improve drainage and supply iron chelates.
Plants respond much faster to iron chelates than other iron sources.
Foliar applications may cause leaf burn if applied when temperatures are above 85F. Direct spray to both sides of leaves. The tiny insects usually appear in clusters on ends of shoots and buds. They leave behind a sticky honedew which attracts ants. Spray plants with a strong force of water or use insecticidal soap, or a recommended insecticide to control. They freckle petals and deform flowers.
