I recently had 16 pallets of sod placed in my back yard that is now dying in the shaded areas. The vendor that sold and placed the job/product represented it as Seville.

Due to the poor condition, I contacted a different service to handle insect control and fertilization. Much to my surprise, that service stated that the "dying off" was typical for Floratam, which is not shade tolerant. They presented a sample at two seperate sod farms for further ID, which both confirmed Floratam.

Based on this info, I contacted the installer and supplier to advise them of the situation. The LS/installer has convientily faied to respond, but the supplier has reviewed the pictures I supplied. Generally, their response was it appears to be Seville, but also requested additional photos for confirmation.

As expected, I have conflicting stories, so I would like to find a source to research the two species myself.

Would appreciate any sources of detailed info.
