3. How to grow mint indoors – hydroponically
It’s also possible to learn how to grow mind indoors by using hydroponics. In fact, mint is a great crop to grow using a commercially made or a DIY hydroponic system. The lack of soil definitely translates to less mess, but hydroponic systems are more expensive than soil-based growing. The nutrient solutions are more costly than traditional fertilizers, too. However, if you plan to grow a lot of mint, hydroponics is worth researching. For some excellent inexpensive DIY hydroponic options and more info on this growing method, I recommend the book DIY Hydroponic Gardens by Tyler Baras.
Best types of mint for indoor growing
You can grow any type of mint indoors. Try peppermint (Mentha x piperita), spearmint (M. spicata), pineapple mint (M. suaveolens ‘Variegata’), chocolate mint (M. x piperita ‘Chocolate Mint’), and apple mint (M. suaveolens). Each offers its own flavor in addition to making a unique-looking houseplant. I love the variegated leaves of pineapple mint!
Harvesting mint indoors
To harvest your indoor mint plants, remove individual leaves as needed, or clip off entire stems for drying or fresh use. Don’t be afraid to cut the plant back substantially a few times a year. This encourages the production of flavorful new growth and encourages a bushy growth habit. I typically cut my plants back all the way to the soil in the mid-spring. This forces the production of all new deep green and flavorful leaves a few weeks later. It rejuvenates the plant just before its period of most active growth.
