Just to set the record straight! "Angel Moss" is actually Sphagnum Moss. It is Sphagnum Moss from New Zealand. I have seen where it grows and where they pick it from..... Definitely Sphagnum Moss. It's latin botanical name is "sphagnum christatum" & sometime they told me it has some 'sphagnum subnitens' (aprox 10%) mixed in with it as that is how it grows together. you can actually see the 2 different varieties once you know what to look for. It is a far cry from Chilean, Chinese & Peruvian moss in terms of quality...... New Zealand Sphagnum Moss isn't "picked by poor natives and sold as gold in western countries" The writer of this comment then suggests to use "Chinese moss" (Talk about poor natives). Obviously the writer of this comment has never done any investigative journalism and if he/she had toured NZ and seen the different Moss companies as I have, they wouldn't be so quick to pass a judgement on what the facts actually are. It is not a mixture of New Zealand, Chile & Peru moss as has been suggested. It is pure straight New Zealand Sphagnum Moss. As the company tells it, Angel Moss is just a brand name. (I guess kinda like Coke is one brand of the Coca Cola Company here in the US). New Zealand moss companies have been selling their Sphagnum Moss to Asian orchid growers, Bromeliad growers, Carnivorous plant growers etc. for 30+ years and it is known to be some of the best product out there. I'm guessing that's why it commands a higher price that other country's Sphagnum Moss. As far as the acidity of it goes I couldn't say exactly. but according to a test result on the Pacific Wide NZ Ltd website it is somewhere around 4.8. If that isn't acidic I don't know what is! I have tried to find information on growing Sphagnum Moss but there isn't much info out there and it is actually quite hard to do. If try and grow some and you feed the moss any type of fertilizer it seems to die, die, die! There is a .pdf document online I found someplace from a guy in England that grew some. but I forget where it is. I have it someplace. The Moss that you buy in store is dried so I don't think you'll propagate it at all. you need growing tips of the Sphagnum probably as it self propagates like this & some papers I've read says that it can propagate from it's seed pod thingy's they open up and kind of spray around like a kind of spore. I think sort of like mushrooms. I found the study that I did on Sphagnum Moss very fascinating and enjoyable..... It was quite a job to find all the facts and information on the subject. Simple.... Do your research People. or visit New Zealand moss companies like I have. they are very helpful and friendly. (incidentally it's a very nice country to vacation in by the way)

I do not believe it is a moss. Perhaps a liverwort? But if your outside air is hot and dry then spraying it a few times a day will not be very successful. You will need to keep the plants out of the wind and sun, in shade on the coolest part of your property. You will need quality water, such as reverse osmosis water or collected rain water. And instead of spraying it you should be watering it at least in the early morning and in the late afternoon, and perhaps in midday if the plant looks wilted. The water should be kept in the shade and be cool to touch. Use a watering can with a fine rose (the nozzle part).

Polyester foam is not likely to make a "good moisture holding substrate" for anything. It is hydrophobic. Also moss, IME, is very slow to bind to foam. Covering the foam with a thin layer of marine/aquarium grade silicone and then pressing in/impregnating the silicone with coir or chunky peat would help.

Moss is pretty much a fact of life in the PNW :-) But you can keep it under control provided you address the reasons it appears in the first place. The reasons for moss development (in no particular order): Poor drainage/excessively moist soil conditions Excessive shade Soil compaction Low fertility Excessive acidity (not typically the case here in the PNW) All of the above are also reasons why the turf grass does not thrive so fixing any or all of the above should get you headed in the right direction. We are now at the end of the window of opportunity for spring overseeding and even if you did, the lawn would not be usable in just a month without damaging the seedling grass. It would be better to just live with the moss for now - it IS green - and focus on a proper renovation in fall. Don't use any peat moss. It will lower the pH unnecessarily and we already have moderately acidic soils in this area. It can also become hydrophobic (repel water) if allowed to dry out. When you do the fall renovation, you need to remove as much of the moss as possible. It rakes up very easily so no need to apply a moss killer. And then you will need to address the reasons it grows so well, so improving drainage, aerating and applying organic matter/compost to boost fertility will be in order. Also test for pH and lime if the pH is below 6.0. When you overseed, the seed needs to come into contact with the soil for proper germination. Overseeding over the moss will not work. Then with your mower on the lowest setting cut you lawn close. Then overseed, cover with a light layer of compost or soil and keep moist but not wet until full germination - about 2 weeks.
