Growing Leeks

G,day gardeners, I was given a bunch of small leeks about 6 months ago which was mid winter here in South Australia. I didn't know anything about leeks so I just separated them and planted in a small ditch. They are now 2 to 3 feet tall and have shot a tall stem up with a bulb on the top of it. I have tried to find out when to harvest them but can't find any clear instructions on this. My question is, does the appearance of this bulb mean they are turning to seed ? Do I need to pull them now or can I leave them growing ? Any info would be appreciated, thank you.

"When leeks have gone to seed, they become tough and inedible. Below you will find some tips on stopping the leek flowering or bolting. Why a Leek Plant Flowers and Bolts. When many plants bolt or go to seed, like broccoli or basil, it is due to warm temperatures. With leeks, it’s different. When leeks go to seed, it is normally due to being exposed to optimal temperatures followed by cold temperatures. In other words, a leek flowering is due to cold weather, not warm weather. When a leek flowers, it causes the neck or lower stem of the leek to become woody and tough and the leek will become bitter. While you can technically still eat leeks are gone to seed, you probably won’t like the flavor". Leeks take about 100-120 days to grow - so if you planted in mid winter (July 14th) it is now 3 1/2 mths - 100+ days - suggestion, pull them out if they look nice and tender - if looking woody, you have left it too late.
