We're not doing too badly, considering the heat.
Bok choy, egyptian spinach, ceylon spinach, rocket, kale, collards, perpetual spinach, swiss chard, mizuma, cherry tomatoes, yellow currant tomatoes, bigger tomatoes (when the fruit fly don't get in first), leb cucumbers, zuch's, criss cross water melon coming on, rockmelon (that were eflavourless), corn (what the rats don't get), basil, parsley, thyme, corriander, and the green manure leaves from buck-wheat and cow peas is making great greens for our morning smoothies. Weeds we also eat - puslane, chick weed, rogue lucerne and the occasional nettles.
But that said, I think almost the whole last plant out of greens last week has succumbed to heat and cut worm or bloody slaters
... not winning this month. But it will soon get cooler, so if this is as bad as it gets we will be right. We're also excited about having new garden beds, so we can put more in -- then what we loose will not have such an impact:)
