RB and I harvested the first of the courgettes yesterday. We are growing Verde di Italia, which are a pale green with superb flavour. We harvested them at around 10-12cm long (4-5 in).
Although there is the inevitable temptation to let them grow to show bench size, the flavour is better when the fruit is smaller and the flesh soft. Courgettes of marrow-proportions lose their flavour and tenderness.
The best time to harvest courgettes is in the morning, using a sharp knife that will cut easily through the flesh. Discard any damaged fruit.
The courgettes will go great with our second harvest of Desiree and Orla potatoes.
