I had 2 ginormous clumps of lemongrass started from very humble grocery store roots, only about 5 bulbs per clump...
I dug one up to pot up for the winter and have fresh on hand. The other one I dug up (as we can't overwinter it here) and plan to preserve it using the food processor/canola oil method.
Due to not having a good clean bucket to hold it in I popped it in the bathroom shower and added some water for it to survive until I could get to it:
I closed the shower door soon thereafter and now freak out when I enter the bathroom because I keep forgetting that I left a HUGE CLUMP OF LEMONGRASS in there and it looks like a person is in there instead.
I probably ought to take that out before my mom visits soon.
Just thought I'd share :)
