Sandberg bluegrass: yellow leaves, causes and fixes

Check these first

Feel the soil two inches deep to see if it is wet.
Inspect the base of the plant for signs of rot.
Check if the area has standing water after rain.

Likely causes

Overwatering
Most likely
How to tell: The leaves turn yellow starting from the base and the soil feels damp to the touch. You might notice a lack of growth despite the moisture.
What to do: Stop watering immediately and let the soil dry out completely. Ensure your planting site has excellent drainage, as this grass prefers dry conditions.
Nitrogen deficiency
Possible
How to tell: The entire plant looks pale or yellowed, especially in older foliage. This often occurs in poor, sandy soils where nutrients have washed away.
What to do: Apply a light, balanced organic fertilizer in early spring. Do not overfeed, as this grass is adapted to low nutrient levels.

When to worry

Stopping it coming back

Only water when the soil is completely dry and choose a location with fast draining soil.
