I grew Malabar spinach this year for the first time, and although I'm unsure what exactly made it so happy, it grew like crazy! I direct sowed the seeds later than I'd intended, I think it was the first of June. My veggie garden is raised beds of decomposed mulch, so it's very well drained, loose and and friable. I used a trellis of twigs and saplings, thinking light trellising like I use for peas would work. By the end of September the twigs were completely engulfed in vines and toppled from the weight of them.
Wish I'd known Chard would sometimes survive the winter, I pulled mine out at the end of summer when it looked really rough.
