How do you harvest Phase Lemons?

I've found Phase Lemon trees in the Ruins area, but they look see-through and I can't seem to interact with them in any way. How can I obtain these fruits?

1 Answer

After finding a tree with ripe lemons on it, just shoot any other kind of fruit at it. This will cause the fruit to disappear and a Phase Lemon to drop from the tree.
