The bacteria may live for several years in the soil or on another host before infesting roses. If bacteria is in the soil, replace it with new soil. Prevent injuries by sterlizing pruning tools with a 10 percent solution of household bleach after each cut. Remove and destroy seriously infected plants. The deficiency is evident by interveinal yellowing of young leaves.
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.
