Hi Fu and whomever else wants to comment.
We planted Ez in August last year, and it has gone very well except for a couple spots. I am not sure if this is shade related, soil related, nutrients being sucked up by the tree or something else. There is a spot where it grew for a little, but then died away and I can't tell exactly why. All treated the same, all with the same amount of water, powerfeed, etc, etc. but this section is poor.
Have a look and see if you have any recommendations:
Before our rebuild that area behind the tree had some concrete and a couple of plants that were very shade tolerant but no turf so I'm thinking its more a shade/nutrient sucked up by the tree problem.
