Milkweed leaves turning yellow is a sign of nutrient deficiency, overwatering, or insect infestation.

To determine the cause of yellowing leaves, inspect the plant carefully. Look for signs of pests, such as aphids or mealybugs, as well as signs of overwatering, such as yellowed and wilted leaves.

To correct the nutrient deficiency, apply a fertilizer that is specifically designed for milkweed plants. If the plant is being overwatered, let the soil dry out between waterings and reduce the amount of water you provide.

Finally, if the plant is infested with pests, treat it with the appropriate insecticide.
