Why Are Your Arrowroot Plant Leaves Turning Yellow:
Causes and Solutions

Arrowroot plants are a popular choice for gardeners who want to grow their own starchy root vegetables. However, yellowing leaves on arrowroot plants can be a sign of stress or disease. In this article, we will explore the causes of yellowing arrowroot plant leaves and provide solutions to help get your plant back to optimal health.

Causes of Yellowing Arrowroot Plant Leaves

1. Overwatering

One of the most common causes of yellowing arrowroot plant leaves is overwatering. Arrowroot plants require well-drained soil, and excessive watering can lead to waterlogged soil, which can cause root rot. When the roots are damaged, they cannot absorb nutrients properly, leading to yellowing and wilting of the leaves.

2. Nutrient Deficiency

Yellowing arrowroot plant leaves can also be a sign of nutrient deficiency. Arrowroot plants require a balanced diet of nitrogen, phosphorus, and potassium to thrive. Without these essential nutrients, the plant cannot photosynthesize properly, leading to yellowing and stunted growth.

3. Pests and Diseases

Yellowing arrowroot plant leaves can also be a sign of pests and diseases. Common pests that affect arrowroot plants include spider mites, aphids, and mealybugs. These pests suck the sap from the leaves, leading to discoloration and stunted growth. Diseases such as bacterial leaf spot and fungal leaf spot can also cause yellowing of the leaves.

4. Environmental Stress

Environmental stress can also cause yellowing arrowroot plant leaves. This can include exposure to extreme temperatures, direct sunlight, or low humidity levels. Arrowroot plants prefer warm temperatures between 65-85°F (18-29°C) and high humidity levels between 60-80%.

Solutions to Yellowing Arrowroot Plant Leaves

1. Adjust Watering Habits

If overwatering is the cause of yellowing arrowroot plant leaves, adjust your watering habits by allowing the soil to dry out between waterings. Ensure that your pot has drainage holes to prevent waterlogging.

2. Fertilize Regularly

If nutrient deficiency is the cause of yellowing arrowroot plant leaves, fertilize regularly with a balanced fertilizer that contains nitrogen, phosphorus and potassium. You can also add organic matter such as compost or aged manure to the soil to improve nutrient uptake.

3. Treat Pests and Diseases

If pests or diseases are the cause of yellowing arrowroot plant leaves, treat them immediately using an appropriate insecticide or fungicide. Remove any infected leaves or stems to prevent further spread.

4. Control Environmental Factors

If environmental stress is causing yellowing arrowroot plant leaves, control your plant’s environment by providing shade from direct sunlight, increasing humidity levels with a humidifier or by placing a tray of water near the plant.
