How timely can it get? I just rec'd two one-gallon lemongrass plants from a DGer. I would like to keep at least one in a pot on the deck. Any recommendations for that, Tamara? And potpourri! I'll have to look for a recipe. I don't like flowery scents in the house - lemon is perfect.
You said 'bulb'? Does lemon grass grow like guinea grass? I see it for sale sometimes, but what is offered is one measly 'stalk' of grass. Would it take long to grow harvestable stalks? Does harvesting a stalk kill the plant, or make it grow more? Would a 50-50 composted manure best suit the most growth? Will it be OK in alkaline sandy mix?
Wow, lots of questions and comments! Glad to see so much interest in this fab grass. Hope I can help...
Use a BIG pot for container-growing of lemongrass. It grows fast and gets big!
I'm not familiar with how guinea grass grows, but Lemongrass grows in "clumps" - you can easily see the different bulb-like clusters at the base of a whole plant.
Mine grows quite large throughout the summer. To harvesting a clump from a potted plant, drive a sharp knife downward right where the clumps separate - this shouldn't hurt the plant as long as you don't cut into the remaining clump.
In my experience, lemongrass does ok in alkaline soil, although ours is clay - it would probably do even better in sandier soil.
Theoretically, lots of nitrogen (like in manure) is good for grasses, so sure, a 50-50 mix would most likely work well.
