What Do Strawberry Plants Look Like?

Strawberry plants are low-growing perennials with distinct characteristics that make them easy to identify:

  1. Leaves: The leaves are trifoliate, meaning each leaf has three leaflets. They are typically bright green, toothed along the edges, and have a slightly rough texture. The leaflets are oval-shaped and often have a slightly serrated edge.
  2. Flowers: Strawberry plants produce small white flowers with five petals. These flowers usually have a yellow center composed of numerous stamens. The flowers are borne on slender stalks that rise above the leaves.
  3. Fruits: The fruit of the strawberry plant is well-known, usually red when ripe, and covered with small seeds on the surface. The fruit develops from the base of the flower.
  4. Runners: Strawberry plants produce long, slender stems called runners or stolons that extend from the main plant. These runners can root at various points, forming new plants and allowing the strawberry plant to spread.
  5. Roots: The root system of a strawberry plant is fibrous and shallow, spreading out horizontally rather than deep into the soil.
  6. Height and Spread: Strawberry plants are generally low to the ground, with most growing no more than 6 to 12 inches (15 to 30 cm) in height. They can spread extensively through their runners.

Overall, strawberry plants have a compact and bushy appearance, combining green foliage, white flowers, and red fruits, making them quite attractive in gardens.

1. Nutrient Deficiency

One of the primary reasons your strawberry leaves turn red is a lack of essential nutrients. Strawberry plants need a balanced supply of nitrogen, phosphorus, and potassium. A phosphorus deficiency can lead to red leaves on strawberry plants.

Solution: Conduct a soil test and amend the soil with a balanced fertilizer such as Jack’s Classic 20-20-20 All Purpose Water-Soluble or specific nutrient supplements to address the deficiencies.

2. Fungal Infections

Fungal infections such as leaf spot and leaf scorch are common culprits behind red leaves on strawberry plants. These diseases can cause red or purple spots on the leaves.

Solution: To save your plant, remove and destroy infected leaves, improve air circulation around the plants, and apply fungicides if necessary.

3. Environmental Stress

Extremely hot or cold temperatures can stress strawberry plants, causing strawberry leaves to turn red. Frost damage in particular, can lead to red discoloration.

Solution: Protect plants from extreme weather conditions by using row covers or mulch to regulate soil temperature.

4. Aging Leaves

As strawberry leaves age, they naturally change color and eventually turn red before dying off. This is a normal part of the plant’s life cycle and not necessarily a cause for concern.

Solution: Regularly prune old, dead, or dying leaves to promote new growth and improve plant health.

5. Insect Damage

Certain pests, such as spider mites and aphids, can damage strawberry plants, leading to red leaves on strawberry plants as a result of their feeding activity.

Solution: Inspect plants regularly and use appropriate pest control methods, such as insecticidal soaps or natural predators, to keep pest populations in check.

6. Improper Watering

Both overwatering and underwatering can lead to red leaves on strawberry plants. Water stress affects the plant’s overall health, leading to discoloration of the leaves.

Solution: Ensure consistent and adequate watering, keeping the soil moist but not waterlogged. Drip irrigation systems can help maintain proper soil moisture levels.

7. Soil pH Imbalance

Strawberries prefer slightly acidic soil. If the soil pH is too high or too low, it can interfere with nutrient uptake, causing strawberry leaves to turn red.

Solution: Test the soil pH and adjust it if necessary. Adding sulfur can lower pH, while lime can raise it.

8. Viral Infections

Viral infections can also be a reason your strawberry plant leaves turn red. Viruses are often spread by insect vectors and can cause various symptoms, including red discoloration of leaves.

Solution: Remove and destroy infected plants to prevent the spread of viruses. Control insect vectors and use virus-free planting material.
