Questions & Answers
No the English walnut is a slightly different species Juglans regia. This one is Juglans nigra. The California black walnut Juglans californica is often used as a rootstock for Juglans regia especially in California.
Note that the black walnuts are often hard to crack, much hard than English walnuts and there are machines built just to crack them.
These seedlings, which are often purchased together (mostly for lumber in lieu of nut production), will cross-pollinate one another. Black walnut trees are partially self-fertile, but will develop fuller kernels if cross-pollinated. If the Carpathian trees shed pollen at the same time the black walnut seedlings are receptive to it in your location, then they should work together. However, it may be more reliable to stick with another black walnut tree for cross-pollination. It's also important to know that wind is responsible for carrying the pollen between trees, so the pollinator tree can be much further away (beyond even a quarter mile) from your tree and still do the trick as long as the bloom times overlap.
I planted 10 seedlings a year ago all with the crown above the soil about an inch or so and all did quite well.
Not too hard to crack when you let your car tires run over them for hull removal. Patience is the key. Once the hulls have dried (they green hull blackens as it dries out) and rubs off under your tire wheels) and rubbed off, then it's time to crack open the shell. My dad gave me a long handled countertop vice but cracker. Does not require a lot of strength at all to crack open each nut. A hammer and a brick work well too! Then picking out the nutmeats begins...again patience is required. It's a process but so worth it!

Yes, that is correct. You will get the best result by planting the seedlings 40' apart.
I live in zone 5b Colorado. I mulched them fairly heavily when I planted them last spring because we are fairly dry here. I left it for winter. They came back nicely this spring. Hope that helps.
