Fragaria x ananassa Yellow Leaves - Causes & Fixes

error

Nitrogen Deficiency

Nitrogen is a mobile nutrient; when lacking, the plant relocates it from older leaves to new growth, causing uniform yellowing (chlorosis) starting with the base leaves. This often occurs in strawberries during periods of rapid fruit development.

Very Common

How to confirm: Check if the yellowing started on the oldest, lowest leaves while newer leaves remain green.

Overwatering and Root Hypoxia

Strawberry roots are highly sensitive to waterlogging. Excessive soil moisture displaces oxygen, causing root suffocation which manifests as yellowing leaves and wilting even when the soil is wet.

Very Common

How to confirm: Stick your finger deep into the soil to see if it remains saturated for several days after watering.

1 Immediately stop watering and allow the soil to dry out significantly to restore oxygen to the root zone.

2 Repot the strawberry plant in a well-draining medium, incorporating perlite to improve aeration and prevent future waterlogging.

3 Ensure the plant is in a container with adequate drainage and use a saucer to catch excess water, but do not let the pot sit in standing water.

Iron Chlorosis

In alkaline soils (high pH), iron becomes chemically unavailable to the strawberry plant. This results in interveinal chlorosis, where leaves turn bright yellow but the veins remain distinctively green.

Common

How to confirm: Examine if the yellowing is specifically localized between the veins of the youngest leaves.

warning

Verticillium Wilt

This soil-borne fungal pathogen infects the vascular system of the strawberry plant, disrupting water and nutrient transport. This leads to progressive yellowing and eventual browning of the leaves.

Common

How to confirm: Check for dark, necrotic lesions on the cross-section of the crown or main stems.

1 Remove and destroy all infected plant material and avoid composting it to prevent the spread of the soil-borne pathogen.

2 Sterilize all pruning tools with alcohol or a bleach solution after every use to prevent transferring the fungus between plants.
