Default To trim or not to trim

I've read different post and online articles and I still can't decide what to do.
I got my centennial hops last year from greatlakeshops. Since I got them as a crown I guess they would technically be 3rd year hops this year. My question is do I cut back all the first growth and let it sprout again or do I just trim them all back except for 3 or 4 bines? Thanks in advance!

And by ^that^ he means cut everything back to the ground, then when the new shoots develop, pick the best 3 or 4 to train...

Cheers!

So can I take a lawn mower to them to level them out with the ground? Haha I know, cheap and lazy solution, but will it be effective?

So chopping off all the bines that have emerged will not kill it? New bines will grow this spring?

"So chopping off all the bines that have emerged will not kill it? New bines will grow this spring?"

Exactly. Hops keep a lot of energy stored in the rhizome. As long as the rhizome is healthy, trimming back the first growth will not have a negative effect on the plant. According to commercial growers, the bines that form later in the spring are stronger, more uniform and likely to put off cones all at once.

"So can I take a lawn mower to them to level them out with the ground? Haha I know, cheap and lazy solution, but will it be effective?"

This is essentially what some commercial growers do (see B-Hoppy's link). However, there have been recent studies that show this won't work well for all varieties. Nugget, for instance typically creates the strongest bines from nodes above the surface:

"Nugget is a hybrid variety that has been selected to produce just a few main primary crown buds; which are formed quite high on the plant stem... The plant root system has survived intact (didn't increase in size, though). Note there are still no crown buds visible! Will it ever resprout? Not sure"

If you dig up a crown that's been in the ground for a year or more, what you see will probably scare you if you remember back to the little thing that you originally planted! As it develops it gains more and more mass and all that mass is usually covered with buds, not to mention any rhizomes that have formed (these will also usually have bunches of buds). Those buds found very close to the surface have first dibs on most all of the simple carbs that were sent back down to the crown after flowering was complete in the previous year. When temps warm up in the Spring, those buds explode with sometimes uneven/unnatural growth due to the ready supply of easily utilized energy. This, plus the fact that most disease spores (if any are present) are usually found on those upper buds. By removing the first growth and allowing the later emerging buds to produce your crop, you help eliminate much of the inoculum for potential disease problems while promoting a more even growth. This also helps to make sure most all of your hops come ripe around the same time. Hope that makes some sense.

If you have 15-20 fat juicy shoots popping out of one plant, how do you decide what stays and what gets chopped? Do you just say, "Oh cool, healthy crown..." chop, chop, chop? Because they are all strong shoots, you won't go wrong? Or is there another indicator?

choose 3-4 and cut the rest off. You'll get a better yeild with the plant focusing on cones rather than foilage, it hurts I know.
