I've pretty much let the Silverbeet do whatever it likes, ie self seed and then grow nicely. I've been harvesting it and eating it, as mentioned here. But recently I took a look at the paths between my garden beds and thought, enough is enough. When you look at this photo below, you probably don't even realise there is a garden path, hiding in there.
So, I came back the next day and 'weeded' the silverbeet into my basket and took it home for eating. It freed up the path, allowing me to move a bit more freely. I'm really diligent about not walking on my garden beds - it compacts the soil, making life hard for earthworms, plant roots and transfer of oxygen in the soil. Walk on paths, stay off beds.
And here's an update photo on the winter vegetables. The great big Silverbeet plant in the middle of the path next to the winter bed has been allowed to stay. I can access the bed from the other side and while the silverbeet blocks the path, I can approach the bed from either end - no complaints.
