I had previously tried growing some organic lemongrass (Cymbopogon citratus), which ended in a resounding FAIL! But then a helpful reader (A Canadian in King Parakramabahu's Court) suggested getting the roots going in a glass first before putting it in the ground.
So I tried it out - after a few days, the stalks started growing out
and there was some root growth
I stripped off the outer leaves
and cut the stalks back too (because someone else had told me that this would encourage root growth)
Only four days later, the results were impressive! Lots more roots
and the stalks have grown back too
I've been lazy since then and have not transferred to a pot, but I will do asap and report back :)
