How To Prune & Feed Mint In Pots To Promote Growth

This is all about how to prune and feed mint in pots (or in the garden) to promote the new growth that we wait to see happen in spring.
Oh mint, what a wonderful herb you are. Not only is your smell and taste extremely appealing and a delight for the senses, but you look great in the garden too. I live in a temperate climate so by the end of January my Mojito Mint was looking like it needed and wanted a good cut back. Plainly put, it had “the funk”. This is all about how to prune and feed mint in pots (or in the garden) to promote the new growth that we wait to see happen in spring. 
This is how my mint looked before I pruned it – scraggly & much in need of a good haircut.Mint is a herbaceous perennial, like some of the salvias. You can think of it as tender above (the stems and leaves) and hardy (the roots) below. In colder climates its soft stems and leaves die back completely with the 1st hard frost and new growth appears next season when the weather warms.  If you’re new to the world of mint and live in a more temperate climate, don’t despair because yours is looking sad come winter. It’s just what mint does. By the way, there are many varieties and flavors of mint to choose from – some are hardier than others.
Here in Tucson, I needed to cut away the old stems. This mint was looking scraggly, leaves were turning yellowish and falling off and the new growth was already appearing in February. Plainly put, you want to cut out the old to bring on the new. You’ll probably need to prune and clean your mint in mid-summer too because it grows like crazy.
Here’s how the mint looked after its pruning & feeding.I’ve found that mint doesn’t need fertilizing because of its natural, crazy fast growth habit. This is why it’s best to grow mint in a pot unless you want it to take over. It does appreciate organic feeding with a handful or 2 of worm compost and a 1″ layer of compost in spring, which is especially true of mint grown in pots. After getting rid of the old growth you’ll want to gently poke the soil a bit to loosen it up before applying the good stuff. 
This shows you the new growth emerging from the lower stems.Lesson learned: next year I’ll harvest and freeze all my mint leaves by mid-January. I use mint every day and want that new growth to appear as soon as possible.  This Mojito Mint is my new fav. What’s yours?Happy gardening & thanks for stopping by,Nell

    Every time I buy mint plants in pots they die within three days. I have tried to grow them indoors and on my patio. What could be the problem ?

    Do these plants deture mosquitoes?

    I bought this mint plant from the farmers market about 3 weeks ago and it was bushy and thriving but now it's leggy with brown stems. How can I revive it??

    I love mint in almost anything. Ice tea, my morning shake, my cooking. Loved video and article. First one on mint!!! Where may I find worm stuff and local compost? Also when I cut mint for use is there a best spot to promote growth? Thank you Georgie Clays central New Jersey gclaysg@aol.com

      Georgie - Mint is an herb I use almost every day. You can find worm compost & compost at a local garden center. They're also sold online. I cut my mint down to where I see new growth appearing off the stems & cut there. Mint likes to be rejuvenated! Nell
