Thanks for the warm welcome.
My 9' Silk Roads are 5 years old, and are planted on the west side of my house near a brick wall. There is a brick wing wall directly north of them also. The soil is the best imaginable. Our summer winds come from the west and south. The lilies do lean a bit once the blooms open, which I like because I can smell them. There's no fertilizer in that bed other than some alfalfa pellets on the roses nearby, and some fish emulsion and blood meal which I use to deter rabbits.
I would call it a fairly protected area, with some afternoon shading from a maple tree nearby. I had to get out the loppers to cut the stems off last fall. When these bulbs were at my last house, I did have to stake them. Here, I put in stakes, but forgot to attach the stalk and just let them grow. We've had record rainfall, so I'm lucky they didn't rot.
That bed must have good drainage.
I'll see if I can find a photo from last summer.
