Even if we’re not saving seed, I like to let brassicas go to bloom so they can feed the bees during winter:
Broccoli, radishes, pak choi – let ’em bolt and bloom if you don’t need the space and you may be surprised by how many pollinators show up. The cool months are a hungry season for bees and those little bright yellow flowers are irresistible.
Incidentally, the brassica and bee photos are by my son RP Good.
I think he has a good eye. He’s always out in nature, spotting something interesting. Now that he has a camera (a used Canon 30D), he is taking his creature spotting to the next level.
