Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and feel soft or mushy to the touch. The soil remains damp long after you watered it.
What to do: Stop watering immediately and let the soil dry out completely. If the pot lacks drainage holes, move the plant to a container that allows excess water to escape.
Lack of sunlight
PossibleHow to tell: The entire plant looks pale and yellow, and it may start leaning or stretching toward the nearest light source.
What to do: Move your wall barley to a spot that receives full, direct sun for at least 6 to 8 hours a day. Avoid placing it in shaded corners or indoors away from windows.

When to worry
Worry if the yellowing spreads rapidly across the whole plant. It is normal for the very bottom, oldest leaves to turn yellow and die as the plant matures.
Stopping it coming back
Only water your wall barley every 7 to 14 days, and always ensure it is in a location with plenty of direct sun.
