I have some concerns with the Franklins Crazy Ed has in the ground. I'm old school taught by commercial growers in Quebec who discourage the use of dry or composted manure as this material tends to be very acidic and my slow down the growth of the tree. Apple trees do best with a PH of 6.2 to 6.7. It will depend on how much is used. Sandy soil works quite well but requires frequent irrigation. I will be interested to hear how well they are doing.
I dont want to get this thread too far off base here but that is way easier said than done Appleman. I'm not a commercial grower, I do understand the desired and recommended PH for apple trees to do best. My farm has been in our family over 100 years and it is what it is, and it is in the middle of sandy central wisconsin. I don't plan to move or buy a new farm, and I do plan to keep growing apples on our farm. Some people think i'm crazy for even trying, but the method I use has proven itself pretty effective in the last 8 years and it does work well.
Planting in a non-amended hole like this is doomed for failure. This sand just does not hold moisture, it's similar to what you find at a beach. If you are lucky you have 1-2" of darker sand on the top. A few bags of the anaerobically digested dairy cow manure at least helps the tree get established. Everywhere you read about black plastic being bad for apples, not in this part of the country, it helps retain moisture. Throw some watersorb in the planting hole too. Irrigation would be great but our area is pretty remote, no well. I did supplemental watering on 1 day in 2012 when I planted 25 trees and we had extreme drought.
I do go against what is recommended by the vast majority of growers, but then again, the vast majority has never been in this area of the country nor tried to grow things here.
I am happy with the results. B118 fibrous roots do best, but M111 does ok too. Here is a 6 year old Liberty on M111. I hand thinned this and many of my other trees, or at least tried to.
I have 5-6 year old trees pushing 15-20' tall and have up to 3" girth. I've seen trees stunted because of over fruiting at a young age but not because of the soil i amend the planting hole with.
I am most curious to see how growing in the sandy soil may or may not impact the flavor of these different varieties, compared to apples grown in ideal soil.
