With plenty of room to grow now, and with an added dose of Vitax fertiliser, I'm hopeful that these two plants will go on to produce a viable crop. If they do, it will almost certainly be later than their earlier-planted siblings, so that may work out well for me in the end, extending my harvesting season.
At the other end of the same bed are some Swiss Chard and Perpetual Spinach plants. I cut them right back, nearly to ground level, a couple of weeks ago, because they were suffering severely with Powdery Mildew. They have responded enthusiastically to the severe pruning and are producing another crop of succulent leaves with no trace of mildew.
