Gave me a bad minute as I racked the old noggin; a quick web search cleared it up for me. Courgettes, or what we know in the States by it's Italian moniker, zucchini is little short of a weed here as there is a bad tendency to wait until the fruit is enormous. Bags are surreptiously left on neighbors steps to decrease the harvest; bread containing the stuff is made in vast quantity and finally as a last act of desperation, ratatouille recipes appear from the back of the recipe file to assault guests with vats of the stuff while chanting the battle cry "It's a taste of summer. Take seconds!"
...Don't become this person. Harvest while they are small and tender but still have a nice firmness the older plant overdoes on the outside and underdoes on the inside.
You have a sooth face; good light. Plant single plants a meter apart. The average household needs no more than three plants unless they are provisioning Mongol hoards (rookie mistake; they sell them in six packs so you plant them in six-packs; break out the ratatouille and Zucchini bread recipes...
Just plant it. Nice soil makes for a better plant, but it doesn't matter really, you can't stop it. It's a machine; the Terminator of the vegetable garden. A nice organic mulch and let it rip. Keep the kids clear while it winds up. Pruning when they get a meter across keeps it tidy and flowering.
I'll be back...
