Allotments 4 All

One of my purple sprouting plants which I only transplanted a couple of weeks ago has bolted.  I have been watering most evenings but I guess it has just been too hot recently. I have cut off the flower  which I managed to catch when it was still small).  Will I lose the plant now or will it be okay? 

I hate gaps in rows of veggies so am really hoping it will be alright

With most brassicas once they have gone for it there is no stopping it, if it was bigger you could cut through the main stem and score the surface, like with cabbages, to encourage a new flush of leaves but it sounds like a gap to me!

you need never have a gap though, my gaps are lettuce patches  :D
