As the title states when do hops stop growing? I live in the East Coast of Canada and didn't get my first year rhizomes into the ground until about 3 weeks ago. We had a rough winter this year and just had our last frost a couple weeks ago. I have read they will stop growing the end of June, but that just seems to early especially since they just got up. Just wondering if anyone from a more Northern Climate has any input on the end of their growing season.
