Mixing 5-1-1 is just in relative proportions. You can use anything of any size; bucket, pot, bin. just measure 5 time bark, one time perlite, one time peat moss. If you are making a big batch just multiply the numbers. I dump all my measured stuff on a tarp and mix them all together and store it in a barrel But if your question is how much you will need to fill two 30 gallon container (60 gallons) , just take roughly 6 gallons per cubic foot. So roughly you will need 10 cubic feet of bark, 2 cf of perlite and 2 cf of peat moss: You will end up with some extra for other potting needs. If you want the total to be just about 10 cf, then take 7 cf (40 gal) of bark, 1.4 cf(8gal.) of perlite and 1.4 cf (8gal) of peat moss. Thing to remember is that 5-1-1 is just a ball park proportion. I may add more or less peat moss depending on how fine or coarse the bark material is. With coarse bark you may also use less perlite because it will have less water retention capacity. In other words : Too coarse bark, too much perlite will end up with a mix with very low water retention. Not exactly a perfect science in a chemistry lab.

Spot-on on #2 Murdannia keisak (didn't know we had invasive spiderworts outside of asiatic dayflower!) and #3 is Cunila origanoides (common dittany). Not sure about #6...

We installed it in our basement. DH wanted it. We picked the most expensive kind they had and tried very hard to scratch the sample with keys. I was fine with him selecting the color and when we went to place the order we discovered they had discontinued it. Ok, so we selected another one and had it installed. Fast forward not long from then and we had some water damage due to our stupidity in the basement that flooded a large section. We had extra flooring but apparently not enough to repair. Well they discontinued that color as well and we've searched all over the country as well as had flooring companies search and can't get it. Maybe it was just a fluke that this happened twice but I'm done with Pergo. The whole thing irritates me. I also couldn't find an email address on their website when I wanted to communicate with them. They did have a phone number thankfully. I honestly also don't like how it feels to walk on it. If not real wood I think I'd rather have vinyl or carpet under my feet. Whatever you go with buy a lot of extra!! I think arcy's DH is correct when she says it looks like a picture of wood with no depth. It just doesn't look like real wood no matter how hard I try to convince myself. It might be the combination of that paired with how it feels under foot.

Wow, you managed to get landscape photos that weren't full of people. I did try, but they all have a stray pair of legs or a couple people in the background. How bad were you? I had 16 hostas by the time I got home, but three were freebies, one was because I needed a "Grace" hosta for a kitty grave and 4 came from a stop in Dubuque. I would have loved Grace Wins, but it's in TC and won't be out for 2 to 3 years. I had to settle for Amazing Grace. Great name but a meh hosta. I had a hard time finding things in the vendor area. In the Country and Bob Solberg's booths were OK, but some of the others were just piles of pots. Jack Barta had nice big hostas on the floor, but I had both hands full and couldn"t get down to read the tags without bumping people. Probably just as well, the garden is already full.
