Thank you for the welcome and I totally agree with your comment. I am a bit annoyed that this has not had more media coverage given that there are so many 'new' gardeners while we are all under house arrest. How are they supposed to know?
As far as I know it is only the Zucchini F1 that has the problem. My Zucchini F1 came from Dobies but I was still a bit hesitant to do the lick test as I only have 1 plant (just me to feed), happy to say no bitter taste so my courgette plant is safe and continues to produce.
