I don't have any photos with decent focus. I'll try again when it stops raining.
My yard doesn't have any places with full sun. They get about 60% sun.
I fertilized when planting according to my best understanding of planting instructions on the LF website (instructions that I couldn't locate again today). I haven't fertilized since. I was planning to soon.
I tracked rainfall with a rain gauge carefully through the growing period. At any time the preceding 3 day total was under half an inch and rain was not highly likely in the next several hours, I watered up to half an inch (so half an inch every 3rd or 4th day during any long dry spell, but usually less after allowing for recent light rain, or zero for at least 3 days after significant rain).
The one in focus photo I have is the largest one after its first little growth spurt a year ago. That small growth spurt made me temporarily optimistic. But it did so little after that:
As long as you brought up watering, correct my assumption: A less established plant needs water on the 4th day dry no matter how much fell the day before the 4 dry days. But these are in theory established, so if they get an inch or more of rain in one day, they don't need any water for a week.
Also, 4 out of 5 of these are at the top of a very steep mini slope: About a 20 inch drop across 4 inches horizontal, with sticks and pine needles on the surface preventing the dirt from washing away. So any more than half an inch of water within a few hours just flows through those sticks and pine needles and out onto level below.
