Kyriolexy

In conifers classification Pinus thunbergiana Franco (as well as Pinus thunbergii Parl.) and Pinus nigra J. F. Arnold (Black pine or Austrian pine) are recognized as different species. They share the same usual care and you can treat them as every two needle pine. The only two needle pine that react in a different way (for example to root pruning and to watering care ) is mugo pine.
