I sowed a F1 Defender courgette seed 4 days ago into a 9cm pot. I can't believe how big it's grown already! It seems to be visibly growing as I look at it. I go into my conservatory every morning with some trepidation, thinking it may have taken over my 5ft yukka plant, or maybe got tangled up in the ceiling fan!
When should I pot it on (there are already signs of thin roots at the bottom of the pot), and what size of pot?
It's destined for a very large patio container in the hope that i can tease some courgettes out of it this Summer.
