Do I list my plants individually or grouped by variety?

Technically the multiples of varieties are referred to as replicates. Please list each plant separately making sure it’s clearly labelled with its experimental number. On the excel spreadsheet use a new line for each plant, for the pdf and doc forms use a separate sheet for each plant and put something like “7 of 9” or as appropriate in the number of plants box to indicate they are individuals within the variety.
If you’ve done the excel spreadsheet there’s no need to duplicate the information on a recording sheet which are for those without excel.
