Hmmmmm... it makes me feel like giving those leaves a nibble myself!
Mine has had no snail attacks, and it has enjoyed the relatively shady and well ventilated corner so much that it has now grown taller than I and 4 xiang gua melons are already developing. The challenging thing about getting this plant to fruit is the pollination bit. The vine functions like a harem. There are countless female flowers and perhaps 1 or 2 male flowers in 2 days... Not only that, the flowers wilt after one day, so you can't get the male flowers to do double duty with new female flowers the next day. As a result, the greedy gourmet in me looks with sad regret upon the spinster flowers which will wilt, and the baby melons they now carry will shrivel away. That means one less melon for me to eat.
