To obtain the Hestu’s Concerns side adventure in The Legend of Zelda: Tears of the Kingdom, speak with the Korok Hestu at the foot of Lindor’s Brow.
Hestu is pointing towards the nearby trees. Make your way towards the hostile trees, which are weak to fire, and take them both out. Afterwards, report back to Hestu. He’s now missing his Korok seeds. If you collect Korok seeds and bring them to Hestu, you’ll get to select which stash you want expanded: weapon, bow or shield. Once you make your selection, you’ll then get to see his most awesome dance and your inventory will be expanded. Afterwards, the quest will complete.
