It's my first time growing courgettes, and was wondering if it's an advantage to remove some of the lower leaves ! Thanks

They look fine and I would leave well alone.  There isn’t any need to remove leaves from courgettes and I don’t think I have ever done it for any plants I have grown.

You do have to check carefully for any fruits hidden under leaves.  Turn your back and they grow into marrows before you spot them

my recommedation is get them into open, outside ground ASAP and like the rest of us, you will be over run with the little green beauties in no time!
