I used metal mesh for reinforcing concrete to make a 2 m high boundary fence between my veg plot and the field behind and then grew squashes such as uchi kuri and Crown Prince up it so they got maximum sunshine and no slugs. One year I grew some yellow pumpkins and a few grew and swelled on the field side. Some b****r nicked them the day before I planned to harvest them. I've been very careful to pull them all through to my side since!
