Question

The babies are called courghettes, so how many of those to a plant?

Some call courghettes zucchini.

Answer 1

Depends on the weather, fertilizer, viability of the seed.  In general, most people find that too many courghettes grow on their plants.  By August we're busily trying to give them to anybody who will take them.
