Strawberries - Deformation
Symptoms
Damage on floral organs and flower abortion. Poor fruit set leads to fruit malformation or bumpiness. Severe deficiency ultimately produces smaller, softer fruit and a lower yield.
Reasons
Boron deficiency
B undersupply commonly results from restricted availibility due to high pH or B leaching from sandy soils.
Strawberries - Chlorosis
Symptoms
Interveinal chlorosis starting from leaf margins. Bronzing, especially of leaf veins, may occur on the extreme edges.
Reasons
Boron deficiency
B undersupply commonly results from restricted availibility due to high pH or B leaching from sandy soils.
Strawberries - Deformation
Symptoms
Interveinal chlorosis starting from leaf margins. Bronzing, especially of leaf veins, may occur on the extreme edges of medium aged leaves. Youngest leaves may show dark, necrotic tips or margins on otherwise dark green tissue.
Damage on floral organs and flower abortion. Poor fruit set leads to fruit malformation or bumpiness. Severe deficiency ultimately produces smaller, softer fruit and a lower yield. Root growth can be reduced with stunted, stubby and brown lateral roots.

Strawberries - Necrosis
Symptoms
Youngest leaves may show dark, necrotic tips or margins on otherwise dark green tissue. Leaf size is severely stunted.
Reasons
Boron deficiency (right)
B undersupply commonly results from restricted availibility due to high pH or B leaching from sandy soils. Necrotic leaf tips can also be a symptom of calcium deficiency.
Strawberries - Size reduced
Symptoms
Poor growth with premature flowering. Leaf size is severely stunted.
Reasons
Boron deficiency (right)
B undersupply commonly results from restricted availibility due to high pH or B leaching from sandy soils.
Boron deficiency made worse by
- Sandy soils
- Alkaline soils
- Soils low in organic matter
- High levels of nitrogen
- High levels of calcium
- Cold wet weather
- Periods of drought
Boron is important for
- Stronger plants
- Healthier plants
- Gives plants more resistance to cold weather
- Improves flowering
- Improves fruit set
- Reduces the number of mis-shapen berries
