What to do if nastersions go yellow?

If nasturtium leaves turn yellow, it may indicate issues such as overwatering, nutrient deficiencies, or pest infestations. Check the soil moisture to ensure it's not overly saturated and adjust your watering schedule accordingly. Additionally, consider fertilizing with a balanced fertilizer to address nutrient deficiencies. Inspect the plants for pests like aphids or spider mites and treat them as needed.
