"I have often thought about growing mint on my own so I decided to try it out. It was a success and I thought I should share the process with my neighbors.
Step 1 - Take the store brought mint bunch and remove leaves leaving only the top 2 layers intact. Step 2 - Take a glass, fill it with water, and cover it with clear plastic cover, like a plastic bag. Poke holes into the plastic with a knife and insert the stems so that only the leaves remain up Step 3 - Keep this glass in a place with plenty of sunlight and keep changing the water every 3-4 days for 2 weeks
Step 4 - After 2 weeks, a well-developed root system will exist, replant this in a pot and you have a healthy mint bush that will be healthy.
I am sharing the picture of my mint planting in the glass. I hope this helps :-)
