I just saw next door growing grape. Could not believe grape can grow in hot weather which is currently high triple digital, low in 70's Would like to know if only grape that can bear zone 9. Thinking about building steel gazabo and lay down dried wood posts on top for grapes to grow on top. Would it be best if I dig out, pour in rich compost and plant grape seed. I have see forum about seedless grape grow seed too. The purpose for grape vine is to give some shade but if it can mature in two years with some grape, but doubt it will be tasty for wine but that will be awesome. JR.
