Have you heard of the Phylloxera disease which invaded Europe in 19th Century?
It was brought back from the USA by a British botanist.
France was the first European country to be hit by the plague.
At the end of the 19th century (1899) Spain was attacked.
All the vines were killed off by this little insect.
What was next for Spain and how did they overcome Phylloxera?
The solution: Grafting.
Grafting involves the connection of two pieces, in this case, of vine material so that they join and grow together as one plant.
