Why is my Sandberg bluegrass looking leggy? Causes and fixes

Check these first

Observe the amount of direct sun the plant receives each day.
Feel the soil to see if it is staying wet for more than two weeks.
Check the base of the stems for signs of rot or mushiness.

Likely causes

Insufficient light
Possible
How to tell: The stems stretch out and look thin or pale as they reach for a light source. The plant will lose its compact, bunching habit.
What to do: Move the pot to a spot that receives at least 6 to 8 hours of direct sun daily. If growing indoors, place it directly in a south facing window. Avoid shaded corners or areas under porch overhangs.
Overwatering
Possible
How to tell: The base of the plant may look mushy or weak, and the growth becomes floppy rather than upright. Check if the soil stays damp for too long between waterings.
What to do: Allow the soil to dry out completely before adding more water. Stick to a schedule of every 7 to 14 days depending on the heat. Ensure your container has drainage holes to prevent water from pooling at the roots.
