Well, I love to have fresh mint tea, and some fresh mint can really improve some dishes, so I've been meaning to grow some for a while now. Typically I buy a bunch like this from the pasar malam (night market)
There are many types of mint, but I think this kind is spearmint, or Mentha spicata. It will cost about RM1.50 (apprx. 40 US cents), but the problem is that mint quickly wilts and goes mushy. No doubt it has also been sprayed with pesticides, etc.
I had been looking around for seeds or plants, and then someone told me that they are easy to grow from cuttings - so I did a quick Google and found this helpful guide (it's a pdf).
First, strip the stalks of the lower leaves (reduces water loss through transpiration apparently).
Secondly, plant in a pot - I just buried as much as I could in the soil as the roots will grow from the nodes where the leaves were.
Importantly, note that mint is very invasive - put it in a pot, or bottomless pot in the ground.
Apparently, you can also get the roots started in water (like here), so I'm trying that too.
It will be interesting to see the roots growing. I put some of my organic vermicompost in the water to supply nutrients.
It will take 2-3 weeks to get some results, will update then.
