Temperatures of 108 were not so good for the hops. As you might be able to make out, many of the leaves browned and curled up, and the whole plant really just shrunk back from the heat.
The Centennial actually fared the best, probably because it wasn’t as overextended as the Galena or Willamette hops were. A point in bad evolution’s favor!
On the other hand, the Galena and Willamette plants have given me hops! Tiny ones, true, but hops nonetheless. I don’t know how usable they will be, but it’s still worth a shot to use ’em.
