The first baby beet seemed ready to be pulled this morning - so I pulled. I'm not sure how you know pecisely when a beetroot is ripe but I read that when the crown starts lifting from the soil it's probably ready. And besides, I've been waiting patiently for two months to eat it !
Next time when I plant my root vegies I'll give them more room so I get a larger crop.
organic, chemical-free - apart from Sydney inner city smog!
