Harvesting: Harvest frequently to increase yield; squash seem to get monstrous overnight. While edible at almost any size, seeds are less developed in young fruit, therefore more tender. Using a knife or clippers, cut squash off including some of the stem. By including stem, the fruit is sealed and less likely to mold or dry out. Harvesting Blossoms: Look for male, non-fruit producing flowers that have long stems and harvest just before use (female flowers have a swollen mini-squash at the base of the flower and are on shorter stems).

I love these Roman courgettes! While I still get plenty of them, they don't seem to go as crazy as "regular" dark-green varieties. They also seem to be a bit slower-growing--they don't turn into baseball bats overnight (we've had a stretch of hot weather after a couple of good rains, which usually makes zucchini grow very quickly). They are very mild-tasting, and delicious. I will definitely keep growing these!
