What soil are best for grape growing?
*Well-drained poor soils
How late- spring frost affect the vines of Chablis, Germany, and how grape growers combat it?
*By damaging new shoots, and that will reduce the yields!
*Smudge pots are placed between the rows of the vines to combat the frost.
Which method is used in New World Countries to combat spring frost?
*Aspersion system- spray the vines with water, the cold air will freeze the water and remains at 0c.
*Helicopters are used in New Zealand and Australia!
