In the foreground of the photo is my redwood rain gauge holder. It's very convenient not to have to stoop to pluck the rain gauge out of a hole in the ground. On the ground are 1x12 planks to walk on so as not to compact the soil.
I mulch with compost now. First I had wood chips on the whole garden as mulch, then only on the paths. Recently I I decided that wood chip mulch, no matter how lauded in the native plant community, has no place in a vegetable garden where you are constantly planting and digging. They are still fine for established native plant gardens.
The trellises are all held together with galvanized wire. I had some complicated over, under, and around style of wrapping the wires but it gets ugly when two cross members meet.
But then I realized that once around is probably just fine. These only have to last a year.
I grew radishes successfully in my raised beds.
My preference is for the round white ones because they have a mild taste. They've been pretty good sliced thinly with balsamic vinegar. I wasn't a radish fan before this, and I'm not one now, but I think they're OK.
