Check these first

- Look for signs of standing water in the saucer.
Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and feel mushy or soft at the base. The soil stays wet for more than a week.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. Ensure your pot has drainage holes so excess water can escape.
Nutrient deficiency
PossibleHow to tell: The older leaves turn a pale yellow while the veins remain green. This often happens if the plant has been in the same pot for over a year.
What to do: Apply a balanced liquid fertilizer diluted to half strength. Feed the plant once every 4 to 6 weeks during the growing season.

When to worry
Worry if the yellowing spreads rapidly across the whole plant. It is normal for the very oldest bottom leaves to yellow and die back as the grass matures.
Stopping it coming back
Stick to a consistent watering schedule and use well draining potting mix.
