Planting hop rhizomes

It’s early May here in Toronto and spring has finally arrived. My raspberry bushes are showing the beginning of their leaves, the apricot tree I grafted last spring actually has 3 flowers, the garlic is up, the grape vines are waking and the spinach and Kale are in the ground. This year is special. My first hop plant will be going in the ground. I was very excited when Canada Post dropped off a small lightweight box at my office yesterday. A few months back, I ordered an organic cascade rhizome for myself and a conventional Willamette rhizome for my bud Eric from one of our favourite brewing supply stores, Canadian Homebrew Supplies. They arrived in great condition, still damp in the Ziploc bags and complete with instructions on how to care for them.

At the back of my yard there is a tall pole that supports both our laundry line and our neighbours. I figured that it would be a perfect spot to plant my hops because these plants like to grow up to 25-30ft in height!

The first thing we need to do after receiving the rhizomes is make sure they are still a little damp – very important. If they’re not, you can use a spray bottle or even soak them in some water for a few minutes. Just make sure they don’t dry out. Next it is important to keep them in your refrigerator in a Ziploc bag until you are ready to plant them in the ground.

From what I’ve read and heard from others, these plants will take over your garden if you let them. Something I’ve done in the past with things like raspberries and blackberries (which will do the same thing) is plant them in either a container of some sort before putting them into the ground, or building a bed of some kind that goes down 2-3 feet so the roots can’t spread as easily to places you don’t wan them to go. I have a bunch of 5 gallons buckets that I got with my fresh grape must to make wine. (Post to come on that one!) All we have to do is prepare them for holding some hops.

In order to do that, we need to drill some holes in the bottom to allow water to drain out, otherwise the hops will drown as the dirt around it gets saturated after any rainfall. The roots may eventually find their way down and out of the holes as they search for moisture, but at that point they should be pretty easy to control, just cut the shoots as they come out of the ground.

To help with drainage, I’m going to add a couple of inches of crushed rock to the bottom of the pail. I only had white decorative rocks that I wasn’t using, but you can use any kind of crushed stone you have access to.

Next you want to mix a good amount of compost (I used mushroom compost) mixed with a little peat moss and regular soil. Fill up the bucket to about the 3/4 mark.


It’s important when you’re handling your rhizomes that you be very careful and not break any of the little buds that have hopefully started growing. You want to place the rhizome vertically with the buds pointing upwards, or horizontally if that way works better.

If you’re just planting them straight in the ground, dig a big hole and mix in the compost and peat moss like we did above. Be sure to keep about 1 foot around free of any weeds. A good mulch will help with this as well as keeping the soil moist. I wouldn’t use any of those coloured cedar mulches, even if they say ‘natural’ or ‘organic. Who knows what really goes into those dyes, I just know I don’t want any of it in my hops and later in my beer!

Now loosely cover the rhizome with about 1-2″ of your soil mixture being careful not to damage any of the growing buds. Then give it a good soaking of water.

For now, I’m just going to leave them in buckets on my back patio until I get a chance to dig out a spot by the pole. I will update with some pictures when I do. It’s been 8 days since I planted them and the first sprouts on the Willamette have just broke through the surface!!

For the first year, the hop plants will be focusing on growing a strong root system, so they will need frequent watering (just don’t drown them!) After the first year and once the root system has been established, less frequent, deep watering will be fine. A drip system is best, but however you water, be sure not to get the leaves and vines too wet because it will promote mold growth that could damage or hinder your plants.

In the fall, cut the vines back to about 4 feet above the ground and add some compost around the base. In the early spring, trim the deadwood and add another layer of compost to the base. In the first year, don’t expect a huge crop as the plant is really just trying to establish itself in its new environment. The second years harvest will greatly increase and by the third, you’ll be in full swing! If I have any hops at the end of this season, I’ll write a post on how to harvest and store those lovely little buds!

Cheers!

UPDATE:
Since planting them 3 weeks ago, the baby hop plants are finding their way nicely. They’re looking very healthy and growing strong. I haven’t been able to plant the bucket in the ground yet as I still have some work to do in the area they’ll be going. I’ll continue to update as time goes on…

  1. you are a mad scientist.

  2. I am interested in seeing how much growth you get from those pails. This might be the option I’ve been looking for. My soil conditions leave much to be desired. Please update frequently!

    • Hey Craig,
      Yes, hopefully a decent amount. My guess is that hops are pretty hardy and as long as you add some good quality fertilizer once or twice a year, you’re good. If they’re anything like raspberries (which I guess is a strange comparison, ha,ha) they’ll be fine, I haven’t touched them in 3 years and they just crank out pound after pound!
      But I will definitely update as things progress!
      Cheers, Jeff
      btw, what’s the issue with your soil?

  3. Hard packed clay. And judging from the attention you paid to drainage, my soil won’t have nearly enough. The only benchmark I have for growth conditions is a couple of trees I’ve planted over the last two years. Progress has been very slow when compared to my folks tree’s of similar species and age. I have a hard enough time getting grass to grow no matter how much attention I give the lawn. This bucket idea could be my saviour. For me, 8oz per plant would be a worth while investment in time.

    Nice work!

    • Thanks man!
      Yes, clay can be hard on most plants.You definitely need drainage unless they’re adapted to such wet conditions. (but I’m no expert on that, just personal experience)
      Give the buckets a try. Maybe you could dig down a little further than the depth of the buckets and fill it in with some sand to give the water some space to drain into?
      If that still doesn’t work, maybe just keep them in the buckets above ground. As long as there’s enough compost and good (organic) fertilizer, I’m guessing they’ll be fine.
      I agree, even 8oz would make it worthwhile and you can tell everyone you grew your own hops for your beer! How cool is that? Let me know how it goes!
      Good luck!

  4. Good idea with the bucket – I just had to dig out a hop plant that was taking over my entire vegetable patch! I’m not so sure about the size of the holes in the bottom, though. The plant I dug out had two quite distinct sets of roots: the rhizomes, which spread out close to the surface and produce new shoots; and the roots proper, which go straight down into the ground. My 3-year-old plant had roots about an inch thick, which went at least a couple of feet down (I couldn’t dig deeper than that). From this experience, I would suggest much bigger holes – or even a bottomless bucket – to allow the tap roots to grow down below the bucket. This way, I think you’d get a strong healthy root system, without the ever-spreading rhizomes.

    • Thanks! That’s quite helpful as I didn’t know that they would grow such a root.
      Perhaps when I go to put them in the ground I’ll either open the holes up or maybe even cut a large hole in the bottom, say 5-6″ to let the tap root find its way down and get a good footing.
      Cheers!
      Jeff
