Nutrients
Cherries - Chlorosis
Symptoms
Interveinal chlorosis and bright yellowing develop first on older leaf margins and tips and spreads back to the main vein. The leaves often have a characteristic herringbone pattern of chlorosis on new season’s growth. Symptoms are normally most obvious later in the season during fruit
Reasons
Magnesium deficiency
Lack of magnesium results in reduced photosynthesis leading to smaller leaves that are lighter in color, as well as poor flowering, reduced fruit size and significant fruit drop.
Magnesium deficiency made worse by
- Sandy soils
- Acidic soils
- Potassium rich soils
- Soils receiving high potash applications
- Cold wet periods
Magnesium is important for
- Combats chlorosis
- Prevents premature leaf fall
- Gives healthier greener trees
