From IRC:

[19:55] <jA_cOp> squeek, I see, thanks. Another thing, apart from BlockCrops, AppleCore has specific support for a number of vanilla plants, right? I see that HungerOverhaul expects the event to also be fired for reeds, cactus, cocoa, melon, pumpkin, saplings and netherwart. Is it implemented for vines?
