Asparagus Fern Turning Yellow. My asparagus fern is going yellow. If planted in full sun the hot direct light turns the leaves yellow.
Asparagus rust is a fungus disease. Spear tops turn yellow and brown and die back. The best course of action is to replant it and add fresh compost to the soil so it gets a nutrient boost as well.
One of the most common causes of an asparagus fern turning yellow is overwatering.
The damage results in the foliage becoming discolored. I dont know how to fix it or whats wrong. Lacy and delicate-looking asparagus ferns grow outdoors in warm climates or as houseplants elsewhere. Too much direct sunlight will cause the needles to scorch and drop off of the plant.
