no, I just protected them today, after loosing 9 heads. If you plant in the basket what do you put on top? I don't see why they can't just get in the basket from top and fest... And another question, how many seasons before the metal will rust to the point of loosing integrity? My lettuce this year is in the concrete blocks of retaining wall,
so planting in the basket is a not that simple, I will have to smash the bottom to fit into the block.
But seems like an interesting idea!
