Hops growing in brazil

[RTrineto]

Hey guys, im from Brazil and im trying to grow hops in my farm. I have 2 rhizomes of cascade 2 of brewers gold 2 of centenial. They growed a loto when i planted then but now they started to get yellow to brown and some bines died. They are well feeded whith a 20-20-20 and 8-46-9 for root growing, aplied once a week. They are well drained and with an auto irrigation system. Here in Brazil we are at the winter begin and temperatures are between 55f and 62f. When i look at rhizome base i see a lot of new shoots but they dont grow.

What im doing wrong? Is it the temperature? Should i prune them back to the soil? They will grow normaly in the end of the winter?

When did you plant? have you already had a harvest? About how much did you water?

Ooops! I just realized I brought back to live a 2 year old post...


I had a rhizome in my back yard, full sun and auto drip irrigation and just now, after 2 months it finally has a little green shoot poking out of the ground. The others are doing very good.

It's winter, your rhizomes are "sleeping". They start growing again in spring. Hop vines die completely in the fall when temperatures get cold enough. The only thing that survives the winter is what's underground.

In your case, it seems that temperatures are not cold enough for the rhizomes to go into a full dormant state, so that would explain the vines dying and a few new shoots poking out of the ground but not growing because they don't get enough warmth during the day.

Try getting the to go fully dormant. Cover them up with a material that will completely block light, maybe a small bucket (upside down) over each one of them. Then lift the buckets every 2 or 3 days to add a bunch of ice over the rhizomes and cover them again. Do this until you start seeing local vegetation start to bud in the spring. At that time, stop the icing and take the buckets away. They'll start growing shortly after.

This would work for your 6 rhizomes. Since you're in a farm, I'm assuming you'll eventually propagate them. At that point, it'll be difficult to do the ice thing once you have more than 10 plants.

If you want to cultivate them, in any significant volume, you might want to relocate to Parana' or even Rio Grande do Sul where the winter weather is a better match for growing hops.

I'm from Sao Paulo, by the way.

I planted in march, end. of summer begin of autumn, this is my frist months of growth, but since may begin it stoped grow.
The side arms didint grow so i dont have any harvest.
My soil PH is 6.1 and im using a half gallon of Walter/ day and my soil is moisted.

Ok, now 1week at the refrigerator 39 f (one day at 10f a huge mistake) 1 week at 29 and rhizomes are back to the soil cause the temperatura here is 76 f.
My doubt is why mu rhizomes are dark brown and why they are a little sagte? What i need to do? Please help me.

Necro thread but I figured this is the one that will come up in searches and it didn't seem worth starting a new thread.

Two teams in São Paulo have been looking at the effects of Brazil vs US terroir - the older one used gas chromatography on Centennial, Chinook, Columbus, Nugget and is open-access, the one from this week used the more sophisticated LC-MS/MS but is paywalled :

https://jib.cibd.org.uk/index.php/jib/article/view/62/95
Although the cultivation of hops in Brazil is a recent development, it has potential with 50 hop cultivars registered (https://sistemas.agricultura.gov.br/snpc/cultivarweb/) and some 50 hectares cultivated with an estimated production of 24 tons (https://aprolupulo.com/). According to the Ministry of Agriculture, Livestock and Supply, the varieties Chinook, Columbus, Nugget and Centennial exhibit good adaptation to the growing conditions in Brazil and are the most cultivated...

The metabolites with the greatest discriminating power for Brazilian hops were trans-α-bergamotene, 2-decanone, and ι-gurjunene, while American hops presented β-copaene, humuladienone, and isopentyl isobutyrate. Notably, trans-α-bergamotene was present in Brazilian hops but absent from American hops.

LC-MS/MS on Cascade, Chinook, and Triple Pearl - https://onlinelibrary.wiley.com/doi/10.1002/cbdv.202501728

The first paper got their Brazilian-grown hops from Brava Terra (https://bravaterra.com.br/) and Lúpulos Dalcin (https://www.instagram.com/lupulosdalcin/) - the latter are in Taguaí in São Paulo state at 23″S so well out of the traditional hop-growing latitudes.

The recommendation of Chinook, Columbus, Nugget and Centennial may be good general advice for anyone else in the tropics?

Thanks for that Northern Brewer. I always heard the C hops (names start with the letter C) did well as you approached the tropics. I'm trying to grow hops and they are fighting me every inch of the way. I'm about 30.1 latt (north of Houston TX right on the hairy edge of the range of hops) and cascade does the best here (although it's a heavy lift), you need to choose the location wisely (lots of sun, southerly exposure) hill them high, keep water on them during dry summer months, cover in the winter (winter is short here but it gets down to the teens). I also have centennial which is doing ok and amalia (which is just barely hanging on).

It seems to be too wet for neo here - all mine died.

Based on your post I'm going to order some Chinook, columbus and nugget and add those next year.

cover in the winter (winter is short here but it gets down to the teens).

That's one thing you don't need to worry about too much - hops are temperate plants and positively benefit from a bit of cold in winter. The classic hopgrowing areas of Europe all get down to -10°C (+14°F) at times in winter, some get down to -20°C (-4°F), and the most important plant in hop breeding came from Morden, Manitoba where the all-time record is -46.7°C (-52.1°F) - not that it's good for hops to regularly get those kinds of temperatures you understand!

In fact one of the reasons that the Golding family don't do well in warm climates is spring dormancy - a "warm" February/March makes the rhizome wake up too soon, then when the shoots get to the surface they realise that the day length is still too short and they go to sleep for a month which then puts them behind for the rest of the year. In the UK warm winters may be more of a problem than hot summers.

Thanks Northern Brewer for the advice on not covering in the winter.
