Hello, I am a new gardener. I added some grass clippings a month or so ago as mulch for my penta/lantana combo. I transplanted the trio from my local nursery several months ago. Now they just don't look healthy. The lantana has always had a strange shape but now there is something going on there too. I am wondering if it is chlorosis, and if so, what kind? I am in the Houston, Texas area, zone 9a. Thank you.
