My passionfruit vine is only 2 months old but soon after planting and ever since, every new leaf disappears over night. I've tried derris dust and pyrethrum sprays. The neighbour has a hybiscus with grasshoppers in it, but they keep eating no matter what I do.

I know how annoying it can be when you are trying to establish a plant only to have all the new leaves disappear overnight. It must be a chewing insect that you have on the vine. We would suggest using a product called Success Ultra. This product, when sprayed onto the leaf has the ability to move through the leaf surface making it resistant to UV light and rain once it has dried. Once ingested, the caterpillar will stop eating immediately even though it may take up to 3 days to die. Grasshoppers are a nuisance as well. They normally shred the leaf sometimes leaving the vein of the leaf in tact. If you continue to have trouble, you may need to put a net over the vine until it becomes a little more established. Good luck.
