How many Worldspan Fern you need
Talent levels 7 and 8 take 1 each and levels 9 and 10 take 2 each: 6 per talent, 12 for Skill and Burst, 18 for all three. Taking every character above to 10/10/10 would take 36, roughly 14 clears of Guardian of Apep's Oasis at 2.7 materials a clear, counting the Everamber and Primordial Greenbloom it also drops as converted with Dream Solvent (the same assumption the calculator makes).
Most players stop well short of that. The Trounce Domain Recommender reads your account export, subtracts what you already own and ranks all 14 weekly bosses by what you are actually short of.
Where to farm Worldspan Fern
Guardian of Apep's Oasis, in Sumeru, drops Worldspan Fern, Everamber and Primordial Greenbloom. Your first three weekly boss rewards each week cost 30 Original Resin and later ones 60. A spare Everamber or Primordial Greenbloom can be turned into Worldspan Fern with Dream Solvent, 1 for 1, so a surplus from the same boss is never wasted.
Which weekly boss should you farm this week?
The Trounce Domain Recommender works it out from your own characters and inventory.
