Non-Chemical Management
- Plants that are chlorotic due to iron deficiency can be helped quickly with an iron chelate spray or soil application. Iron deficiency chlorosis is more common in alkaline soils or those to which lime has been recently added.
- If soil is high in lime, add sulfur or incorporate organic matter.
- Choose the right plant for the location. Some plants can tolerate more sun exposure than others.
- Proper irrigation during hot weather can increase the plant's resistance to sunscald.
- Provide partial shade with other plantings or move the plant to a less-sunny location.
- When applying nitrogen fertilizer, use only the amount needed for reasonable plant growth. Incorporate it into the soil, and only apply it during periods of active growth.
- Identify the cause of the chlorosis before purchasing and applying fertilizer.
- Give careful attention to the amount of water applied to sandy soils, where nitrogen can easily leach away.
- Do not overwater.
