Ok here is my recipe for the perfect hole. First off I dig a 4x4x4 hole. Then line the hole with a black lawn bag and punch lots of holes in the bag (this helps keep more of the moister in the soil and the holes in the bag help with a bit of drainage. I keep all the rocks I pull out of the hole and line the bottom of the hole with at least a foot of river rock I put all the dirt form the hole on a black lawn and garden bag. I do all the mixing of the smaller rocks and amendments on the extra bag so as to make sure i have the best mix and I don't lose all my dirt from the hole. I find the best thing you can bring for holes is water polymers mixed at 1 tbls per 1 square foot (4 tbls. for one of my holes) I gather tons of amendments from the area your area is probably different but with a bit of scouting and maybe a bit of reading you can make some REALLY KICK ASS HOLES. i.e.. dead trees that have dried out in the sun are awesome the mulch it is perfect in place of coconut coir if you just cant get any and it will just make the hole that much better next year. Cow and horse manure that is dried and somewhat broke down are great for high N's. LOTS of river rock to help break up the density of the soil. I am fortunate enough to have some great soil at the SPOT (lots of good black soil and no clay until 4 almost 5 feet down). As soon as I get the soil mix just right just pour the soil on the bag in to the hole. NO WASTE. It has been said a million times but the more time you spend on you holes the better the payoff. Make them big and deep use what you can from the area and mix it well. The bags in the holes WITH HOLES PUNCHED IN IT is just a cant miss trick lining the bottom of the holes with the larger rock before pouring in the soil you worked so hard on can only help make the physical part well worth it. This is my recipe for a good hole. Please post any replies and criticisms this all about learning and shearing.
