If you suspect nutrient deficiencies, proper fertilization and premium plant foods can help. Your local county extension agent can also shed light on the specific nutrients involved. Identifying which leaves turn yellow first and how the yellowing starts provides clues to common deficiencies 1 such as these: 1 Nitrogen deficiency shows up as a general yellowing. Older, inner leaves turn yellow first. As it progresses, yellowing moves outward, eventually reaching young leaves, too. 2 Potassium deficiency shows itself when leaf edges turn bright yellow, but the inner leaf stays green. Older leaves show symptoms first, and leaf edges soon turn brown. 3 Magnesium deficiency starts as yellow patches between leaf veins on older leaves. Veins stay green as yellow moves from the leaf center out. Leaf edges turn yellow last. 4 Iron deficiency also shows as yellowing between leaf veins, but it hits young leaves on plant tops and branch tips first. 5 Sulfur deficiency starts with the newest leaves, turning them yellow throughout.

What causes primroses to rot?
Primroses growing in warm, humid conditions or excessively wet soil may develop bacterial soft rot. This infection, caused by Erwinia carotovora bacteria, occurs most frequently at temperatures above 76 degrees Fahrenheit.

Preventive measures include spacing the plants for good air circulation, watering them from beneath and protecting them against wounds that invite infection. Control existing bacterial rot by removing and destroying diseased plants as soon as symptoms appear.

What causes yellowing of leaves?
Insects, Pests & Diseases That Cause Leaf Yellowing 1 Insect damage can cause yellowing when leaf tissue is damaged and when leaf sap is extracted, such as by caterpillars, aphids, and spider mites. Damaged leaves decline when water and nutrients are cut off 2 Ground-dwelling pests such as gophers can damage a tree’s root system. The stress of lost roots is compounded by reduced mineral and water uptake, resulting in leaf yellowing from chlorosis. 3 Bacteria and fungi can reduce a tree’s photosynthesis, water, and nutrient levels. For example, powdery mildew covers a leaf’s surface, limiting the amount of sunlight reaching the leaf’s surface, while verticillium wilt clogs a tree’s internal vascular system and prevents the transfer of water and minerals to leaves. These and other diseases cause affected leaves to become stunted, turn yellow, or wilt.
