I would not bother using the Espoma if you have already planted moss. I think the Espoma is best dug into the soil before planting. Also a pH of 7 is ok for mosses. Not all mosses like acidic soils. What you need to test is your water. Is it quality water, like rain water, deionized, or reverse osmosis or just city water that is buffered to 7.0. The biggest problem for any moss would be salt build up on the moss if your water is hard. If the house is older check the outside faucets to see if any kind of salt build up is evident on the tap. Otherwise don't worry about the soil.

It is really too hard to tell from your images. If the mosses were hydrated then maybe. All I can do is guess and that would be Brachythecium for all 3

Hmmm . . . I've been looking at photos of 'Indigo,' and you're right, it does look a LOT like it! The leaves look right, too. This rose is smaller and has a higher petal count than the descriptions for 'Indigo,' though . . . I wonder whether those depend on growing conditions? I think this rose is a once-bloomer, but I could be wrong . . . I'll have to go out and check on it a few times this summer to see whether it blooms again.

Firt off, how wide is your window? I have an 8' wide window in my LR that I had custom drapes made by Calico Corners and a custom measure--paid way too much for them, but learned a lot in the process. They stack back fully on each side. I just measured and the stack is about 22" per side which I think looks about right, though at the base they fan out a bit since they are really full. They are fully operable, pinch pleats. Here they are just after installation: As you can see they are designed to stack back to the sides of the window--even behind the window trim, though in my dining room there was less room on the sides to accomodate the rod, so the stack only cleared the sides of the window (not the trim): Note they are also installed closer to the ceiling as they ceilings are 8' and I wanted to raise the eye. See the little silver things on the rod? Those are supports which I still need to paint the covers. Mine are that way as it's a traverse rod that I can fully open/close contrasting with fivefootzero's wooden supports (she has two). With the wooden ones you cannot pull the drape beyond the support, hence you have very important decision to make do you want privacy or not? You can still get privacy without going custom, but your response will help me better frame what to say next. Stationary panels are just that--they are dressed in attractive folds and left that way. You may be able to ope/close them, but they don't have that same look you see in the pics unless you "dress" them. Pinch pleated drapery are meant to open/close and the folds fall naturally withoout any "dressing." If you just want to do stationary panels with a really wide window some elect to install two shorter rods to either side of the window (there is an example above) instead of seeing the really long rod dividing the space. If you opt for stationary panels, I think this could be a good look for you. HTH
