Has anyone bought chestnut trees from https://www.burntridgenursery.com/Chestnut-Trees/products/53/2/0 , and did you have a good buying experience if you bought from them? They have a 4.2 stars out of 5 star rating according to Google search I did. Also what's the difference between seedlings and grafted trees, and is one type better than the other? The site has seedlings and grafted trees for some of the trees they sell. Has anybody planted either the Chinese or Japanese chestnuts, and which of those 2 do you think is better?
