I have two chestnuts that I recognize as such on my camp property. One is a dunstan, per the tag, which has not fruited yet. The other is older and has been producing for a few years at least. I think it may be a Chinese chestnut but not certain. Each year I’ve found a few well developed chestnuts and a few more that the squirrels or deer got. But most of the husks are filled with shriveled nutlets about 5/8” and flattened. I haven’t seen any evidence of weevils. The pH is generally 4.9 in our soil without a liming effort which puts the soil within the range that chestnuts are supposed to like.
Are there any hints that may help me overcome the low yield? Should I plan to plant another one to increase cross-pollenation? I’m considering adding a good base of leaf mould and pine straw mulch around the drip line.
