It does eat the worst of the weeds, which is great–but it also chews on young fruit tree trunks. The most vulnerable are enclosed in heavy-duty Erva bunny -proofing cages, highly recommended even though they’re pricey, so that’s not an issue there.
The mango doesn’t have one. It probably should.
I want to put the rest of my sunflower seedlings out there but you know they’d be gone in a night. I do need to buy more Ervas.
Pro tip: do not follow the instructions to stake the cages to the ground: you want them to rattle when a possum or raccoon tries to climb over it, because then they won’t. Mine don’t.
