For all my self-labelled black-thumbed friends out there :)
These are all very easy to grow. I’d also add silverbeet and cherry tomatoes to this list as well. At this time of year, all of these will do better with a good few hours of sun each day (in summer, greens prefer part shade or they will bolt to seed and you won’t get any yummy leaves) and only need to be watered every other day. And there’s no need to make or buy a garden bed for them; all of these are happy being in pots, or even just a freebie styrofoam box with some holes poked in the bottom and filled with compost.
