About this seed family
European breeding programs assign numbers to selections coming out of trials. T0613 is one of those, carried forward for its disease tolerance and vigor.
Like Marsol, its strength is resistance to Phytophthora root rot rather than blight.
A good companion to Marsol on the wetter or heavier portions of a planting.
For deer hunters. Solid mid-season drop with hybrid nut size.
Straight talk. Less documented in the Midwest than the named French cultivars. Treat it as a trial family.
What you are actually buying
This is a seedling grown from a nut produced by a named T0613 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.
Plant more than one. Chestnuts need cross pollination from another chestnut nearby to set nuts. Plant at least two, ideally five or more, within a couple hundred feet of each other. Mixing seed families also staggers your drop window across the fall instead of dumping the whole crop in two weeks.
