Continuing the green roof installation

Here is another bunch of creeping sedum. This package contains 400 cuttings. The person Ibought it from on ebay also suggested that I should divided the cutting if it was longer than ten inches. she said they grow better if they are short. So I included scissors in my tool kit This is the almost completed green roof. I have about ten trays left to go. But surprisingly I have about 20 bags of soil left. I guess I'm committed to doing more next year. I really don't want to do more now. I want to see how this goes this fall, over the winter, and especially next spring when these sedum should really start to fill in. This is a close up view. I think I have about 25 different kinds of sedum up here. It's hard to keep track because I bought some lots on ebay that were just labeled "20 assorted cuttings" Here is a list of the stuff I bought and the cost.

100 trays from Growers Supply-$120.00 2 cubic yards of Gaia Soil from the Gaia Institute $240.00 1 20'x 15' 20 mil. pond liner from Fishfarmhatchery on ebay. this is the root barrier. $60.00 I spent a total of $255.00 on plants. I'll list them next. This totals $675.00 This comes out to about $3.40 a sq.ft. The plants I definitely bought in a haphazard manner. I didn't plan on doing it this way but I got sucked into buying cutting on ebay. hopefully it will work out. I originally planned on only buying plugs from an established green roof nursery like Mountain Crest Gardens or Emery Knoll. But I think this was more fun. I bought stuff on ebay from 5 different people. I bought a total of 8 different listings. This includes 700 cuttings of creeping yellow sedum from 5 different lots. I spent about $65.00 on this stuff although it probably makes up over half the space. I also bought 6 different listings of other stuff on ebay.Three of these were Sempervivium or commonly known as "chicks and hens." But the other 3 lots were assorted sedum cuttings. The total for these 6 lots was about $70.00 Then I bought 1 tray of 84 sedum plugs from Mountain Crest Gardens for $78.00. and finally I just bought at half price 12 sedum plants at Lowes for $10.00. I also bought two packets of seeds for $4.00 This is a picture of my house in Jersey City NJ. So you can get some idea of where you are when you see pictures of the roof. This is a flat of 84 plugs of various types of sedum. It came from Mountain Crest Gardens which is in California. It cost about $78.00 including shipping. there are 12 different types of sedum. The next picture is the list they sent me. This is an out of focus picture of a bunch of little bags. Each bag contains a different type of sedum. It was very enjoyable having all these little bags of plants. These came from "Mom's chicks and Hens" It sells on ebay. This is what was in one of those little bags. these are cuttings of Dragons Blood Sedum
