Why did my Ribbon grass die?

Planted 12 grasses last spring. Grew great summer and fall with blooms.  Cut back this spring and no growth at all.  What happened?

Hi bshearer in Lakeland Minnesota.

Thank you for your question.


Great to hear from someone who lives in my home state!


The Ribbon grass is tolerant in zones 4 thru 9.  It looks like you live just outside the St. Paul-Minneapolis area.  If you had a very cold winter and you did not adequately cover & protect the roots your Ribbon Grass, the rhizomes may have frozen in the cold winter weather. Your area is in a boarder planting zone for the Ribbon Grass.


In the spring time, it is a good idea to us a good compost around the roots of your Ribbon Grass to help feed the plant after its cold winter exposure.  Work some rich organic material 6-8 inches in the ground around your plant in the spring time unless you already have an organic soil.


Place about 2 inches of a good mulch over the top of your Ribbon Grass to help keep the soil cool and to retain moisture.


This grass does best in a well-drained soil, but does need regular moisture and should never be allowed to dry out.  When you trim your Ribbon Grass in the spring, just cut back to about 6 inches.

Check to see if you have any healthy rhizomes left in the ground.  You may be able to salvage some. However, it sounds like they may not have survived at all if they have not even sprouted yet.  It may be necessary to replant. 


Please let us know if we can be of further assistance.
