Harvesting

You will find three chestnuts in a bur regardless of whether or not the bur got pollinated or the seed are viable. Pollinated seed are plump and sink when placed in water. Unpollinated seed look shrivelled up and float after placed in water (** float tests should be conducted for approximately 24 hours. Some floating seed do germinate. It will be up to you whether or not to discard floaters after the test).
