Japanese horse chestnut can be grown in USDA zones 5-7. It
is tolerant of a wide range of soils provided they are well draining. When
growing Japanese horse chestnuts, situate the trees in full sun.

Plant the tree either in the spring or fall depending upon your climate. The
planting hole should be about three times the width of the root ball and deep
enough so that the root ball is flush with the soil.
Place the tree in the hole, making sure it is straight, and

hole with the soil. Tamp the soil down lightly to remove any air pockets. Add a
layer of mulch to retain moisture and retard weeds.

beyond some pruning in late winter.
