Chestnuts will not thrive where they must tolerate wet feet. Standing water during any part of the season must be considered a negative signal for a chestnut grove. Chestnuts break dormancy with the oaks, and are among the last trees to begin their foliage season. Blossom in northern Michigan will generally not occur until early July. Harvest commences about the first week in October and is usually completed by the third week.
More southern regions are proportionately earlier.
In Tennessee, for example, early chestnuts may be ready for harvest in early September. Most new chestnut orchards are being planted at a density of about 100 trees per acre. This translates roughly to a 20 x 20 foot planting scheme. Some new orchards in Australia are being planted as closely as 14 x 14 feet. Mature Asian chestnut trees may require up to 40 feet if trees are unpruned and allowed to grow to full size.
