Various nutrients are indispensable substances in the growth of strawberries. In recent years, with the continuous increase of strawberry cultivation, due to limited conditions, strawberry nutrient deficiency is becoming increasingly apparent. So, what are the symptoms of strawberry deficiency?
Symptoms of Strawberry Nutrient Deficiency
(1) Nitrogen deficiency
When strawberries lack nitrogen, the leaves initially turn yellow green, and later the serrated edges turn red, gradually developing from the outside in, and even the entire leaf turns orange red.
As nitrogen deficiency continues, the brown color of the next mature leaf becomes deeper and the leaf edges appear brown. Root growth is inhibited, weight decreases, and plant yield decreases.
(2) Phosphorus deficiency
When strawberries are lacking phosphorus, they first appear purple on the fine veins of the old leaves, and then the thicker veins turn blue purple. The entire leaf turns blue purple, and the growth of the creeping stem weakens.
(3) Potassium deficiency
When strawberries lack potassium, the first thing is that the serrated tips on the leaf edges turn red and develop inward. The base of the midrib and the leaves do not change color, but remain green. The creeping stems are short and thin.
(4) Calcium deficiency
When strawberries lack calcium, the first thing is that the newly formed leaf tips become scorched, the leaves curl, but the petioles are normal. As symptoms develop, newly formed leaf distortion gradually becomes severe.
In the center of the leaves of the old creeping stem seedlings, light purple brown stripes are formed and lose green. Mother plant 1 generally does not exhibit chlorosis symptoms, but this symptom can also occur when calcium deficiency is severe. Most calcium deficient plants have underdeveloped flower organs, fewer fruit seeds, and deformed fruits.
