These all sounds great. Better than with what I started. Kathy, I'm 45 :) Dweeb is something I hear often since I work with a bunch of nerds. Heck, for Christmas I gave my boss a plaque with his name spelled out using chemistry symbols and the definition of a "geek" (or was it nerd?). We're proud to be dweebs, usually. Just not this time! Nerds are salt of the earth.

Thanks. Looks like she has planted them everywhere with no regard to location...

Awesome! Having a specific list of plants is so helpful. Completely agree with ez for the Echeveria and Crassula - you have a lot more to gain from a better soil like gritty mix than a bit of additional stress on the plants. For the Sedums, just be careful when you repot. S. morganianum can be pretty fragile but will grow back. Any leaves that fall off your S. rubrotinctum can be easily propagated by laying them on top of gritty mix. I'm going to assume that Senecio radicans is similar - people have mentioned using a bent paper clip to hold similar plants down, if they don't stay put in the gritty mix before the roots get re-established. Schlumbergera bridgesii will not do well in gritty mix, it's an epiphyte / tropical cactus. Normally grows on other trees in the jungle. Some people are growing them very well in just fir bark fines (same stuff as for gritty mix). Bark is very expensive in Canada, so I'm growing my Schlumbergera truncata and buckleyi using a mix of large perlite and granite grit. Rina suggested this mix to me and it's working quite well!

I think you have some very good materials there. I really don't think it have to be complicated science. Personally I would just put them down now, just mulch all your raised beds with them, I don't think it matters which goes first because it'll be composting over the winter and by spring time when it's warm enough for growing all the materials would be broken down. Problem with having a thin layer is that if you have just scattered stuff on top, they oxidized and dehydrates (if no rain) and doesn't compost well as in a big pile. It may be better to have grass clippings on top because it creates a good seal to keep the soil warm, retains the moisture and help the composting activities. If you were growing at the same time you put these materials down, I would put more broken down/composted materials down first, then the more green and coarse on top. Stuff like unbroken down woodchips can tie up the nitrogen in your soil a bit if you mixed in while it haven't composted. But since you mixed your wood shavings with chicken manure, and leaving it over the winter to compost, it is not a problem. I don't believe in doing all the complicated composting methods and separating things, organic matters is organic matters for me. So I would just throw them in. You can check out the youtube channel "OneYardRevolution" where the guy improved his soil simply by mulching with leaves and adding compost over time.
