You can plant hops just about any time of the year (with the exception of downright freezing weather). Spring is a good time. If you have healthy rhizomes, you may even get a small crop the first year. Regardless, they WILL grow, it's almost impossible to kill the little buggers, they are very hearty. Be prepared for the next year's crop because it will be much bigger! Third year and up they wil go crazy. Have fun!!
