Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Need help with dying clumps of Cedar Sedge
Answered by: Jimmy Mills

QUESTION:

Carex planostachys. This grass was planted 2 years ago in light shade. It grew well until this year. Now some clumps are dying. Others in same area look fine. No insects can be detected. Why are some plants dying?

ANSWER:

Other questions to ask that may help answer the first one are; Has the growing environment changed? How are the conditions around the growing clumps different from those around the dying clumps? 

Take a look at the NPIN page for Carex planostachys Carex planostachys (Cedar sedge), and note its native habitat and growing conditions. How do they compare with where you are growing your Cedar Sedge?

For some help closer to home, you could contact the folks at the Dallas Chapter of the Native Plant Society of Texas (NPSOT).
