grapes house

i just planted grapes in a polybag. can someone teach me how to do house for grapes? please show some of pictures of it. and some tips to help it bear fruit.

Not sure what you mean by house for grapes - can you explain a bit?  

Where I live, it's just a little bit too cold for grapes, so we grow them in the greenhouses that we have anyway. What climate are you in, and why do grapes need to be housed where you are? Or do you mean trellis (support for vines like grapes)?

Are you looking for something like this:

Hoop House, row cover, cloches or a cold frame?

hi I'm from Philippines,a tropical country, I need a photo or just relate how trellis can be used for grapes. Thanks

Okay, polybag is not very good for grapes, they need room to do a serious root system. They need to be in the ground. They like nice deep rich soil, vinyards often put in good soil to a depth of a meter. So hole prep should be a very large hole, then backfill as needed to put your vine rootball in.

A support such as a large rot resistant piece of dimensional lumber should be put in at the same time. I am not growing wine grapes, I use two steel T posts (fenceposts) about 2 meters (6.5 feet) long before being driven into the ground, about a meter on either side of the vine base. I ran mine north and south, then used heavy aluminum (what I had) wire to put between the posts starting at about 15 centimeters (6") from the ground and going up every 15 centimeters and trained my vines to that. I am not trimming my vines out other than dead wood, some do trim back growth.

I have table grapes, concord, red, and a green seeded eating grape. The vines are spread out to allow maximum catching of morning and evening sun, and allow me to find the fruit more easily at harvest. If you use the dimensional lumber, then often it is topped at about a meter and a half with a crossarm going one way, to again spread the vine out and allow it more access to sun and ability to find the fruit.

I have planted vines several places and it always takes 4-5 years for table grapes to get a good root system and get really going on producing well. I have lost a lot of vines in the first two years. Where I am now it is at some altitude and we can have very brutally hot summers. The vine of four that I planted that gets the most winter wind shelter, and summer afternoon/evening shade from my house does the best. The next best spots are farther from the house, and the one at good shade but took a lot of the summer winds, only lived a year.

You say violet/purple grape, is that an eating/jelly grape then and not the really small fruited wine grapes? I have found that Concord (a purple classic table and jelly grape) has done the best for me. But always in the ground.

The weight of a vine with leaves and fruit after 4-5 years will be close to the weight of a person so it does need some serious support.

They built a new grape arbor at Wheaton Labs.  It is really cool.  I can't wait to see it in action.  Watch the video here: https://youtu.be/OBoaYFSSeAg?si=dU5GzR8O0bExDCKW\
