About this seed family

Marsol is best known in Europe for resistance to Phytophthora ink disease, a root rot that kills chestnuts on poorly drained ground.

If part of your planting is heavier clay or has a history of wet feet, this family is worth a look. It is not a license to plant in standing water, but it tolerates more than most.

Very vigorous growth habit.

What you are actually buying

This is a seedling grown from a nut produced by a named Marsol Family parent tree. It is not a grafted clone and we will never sell it as one. It inherits roughly half its genetics from that known mother tree and half from whatever pollinated her, which means you get a real head start on quality plus the seedling advantages of a natural taproot, lower cost and genetic diversity across your planting.

Every tree is started in our insulated shed under grow lights and grown in a 4 inch by 12 inch deep tree pot, so you receive a well-rooted young tree with a developing taproot rather than a root-bound plug.
