Common Cultural: Nutrient deficiency

Biology

An insufficient supply of mineral nutrients can result in a variety of symptoms on plants. Nitrogen deficiency typically causes a chlorotic yellowing of older leaves. Iron deficiency symptoms are observed on the new growth as interveinal chlorosis (leaves yellow between the veins, while the major veins remain green). High pH soils which bind iron can cause tip chlorosis and necrosis on certain plants. Magnesium deficiency can also cause interveinal chlorosis. Boron deficiency can cause necrotic spotting or flecking on leaves.

Management Options

Use Integrated Pest Management (IPM) for successful plant problem management.

Non-chemical Management

Select non-chemical management options as your first choice!

• Have your soil tested for pH and nutrients. Fertilize accordingly.
• Remove construction debris from soil. Lime leaching from concrete can raise soil pH and affect nutrient availability.
• Root damage or disease, or trunk or branch injuries such as sunscald, cankers, or bark damage from string trimmers can impede nutrient uptake and distribution.
