Overwatering and Root Rot

Oriental lilies are sensitive to poorly draining soil; excess moisture suffocates the roots, leading to systemic yellowing (chlorosis) starting from the lower leaves of the plant.

Very Common

How to confirm: Gently lift the bulb or check the soil depth to see if the roots appear dark, slimy, or have a foul odor.

Liliom Corpusculum (Natural Senescence)

As the blooming cycle for 'Premium Blond' concludes, it is biologically normal for the plant to redirect nutrients from older leaves to the bulb, causing them to yellow and die.

Common

How to confirm: Observe if the yellowing is limited only to the oldest, lowest leaves while the top of the plant remains vibrant.

1 Allow the yellowing leaves to wither naturally on the stem; do not remove them prematurely, as they are still transferring vital nutrients to the bulb.

2 Once the leaves have completely turned brown, prune them cleanly at the base of the bulb to prevent fungal growth.
