Drought is a more common problem than extreme wetness at our farm, so I planted all of the trees in a depression in an attempt to channel a little more water to the trees.
Of course, the first spring and summer were very wet at our property. I lost 5 out of 6 trees. I believe the problem was several months of water saturated soil did not allow enough oxygen and the roots subsequently died.
If you are in an area with good annual rainfall, you may need to plant your chestnuts on slightly elevated ground for them to thrive.
