Hello Bella, mine too with slender roots but what I'll be doing shortly is to cut the leaves almost to soil level so that the plant has less above and encourages the root growth instead of all the goodness above. By the way the leaves are also usable. Is yours in a pot or in the ground? I've been growing in both, the potted ones are for anyone who would like to grow their own. Celeriac I haven't grown but celery yes. If you miss the Browns Plains exit no worries if you find your way your way to Logan Central from Ikea , Wembley Road it's just a matter of going all the way to the end and that is crossing over Browns Plains Road then it's just a matter of a left and a left again.
