Does my milkweed need fertilizer?

Usually, no. Common Milkweed is a tough native plant that thrives in average soil without extra feeding.

Is yellowing a sign of a disease?

Sometimes it can be, but it is almost always related to water or soil conditions. Rule out drainage issues before looking for pathogens.

Common Milkweed: yellow leaves, causes and fixes

Check these first

Feel the soil moisture at a depth of 2 inches.
Check the drainage of the area where the plant is growing.
Look for signs of root rot or mushy stems near the base.

Likely causes

Overwatering
Most likely
How to tell: The leaves will turn yellow starting from the bottom of the plant and moving upward. The soil will feel consistently damp or soggy to the touch.
What to do: Stop watering immediately and let the top 2 to 3 inches of soil dry out completely. Ensure your planting site has good drainage and is not in a low spot where water pools.
Nutrient Deficiency
Possible
How to tell: The leaves turn a pale, sickly yellow while the veins remain green. This often happens in poor or very sandy soils.
What to do: Apply a thin layer of compost around the base of the plant in early spring. Avoid heavy synthetic fertilizers, as they can encourage weak growth.

When to worry

It is normal for the lowest, oldest leaves to yellow and drop as the plant matures. Be concerned if the yellowing is widespread or affecting the new growth at the top.

Stopping it coming back

Water deeply but infrequently, allowing the soil to dry out between sessions. This encourages deep roots and prevents moisture stress.
