Peppermint plant

Susie Dewey CornwellAnne WingateMaghi Geary


I bought a peppermint plant and planted in a clay pot. I wanted to bring in my sun room to have fresh all winter. Was full and green and I sprayed it off to make sure no bugs. Brought in before it gets cold out and its starting to look bad. Plenty of light and water so not sure what's wrong, had 1 die last year so I planted into a different pot when I bought this 1. Any suggestions?

    did you re-pot it and what spray was used?

    Don't over water
  • What did you spray it with? Mint plants typically are not prone to bugs, most people plant to get rid of bugs.

    At this point, prune back the dead parts. You can go as low as 1" from the base. If you did more than just spray the mint with water to dislodge critter, give it a nice little bath of soapy water and rinse well. Mint is meant to be eaten and bug spray on it can linger and be bad for the person eating it as well as the bugs as well as the plant.

    Mint grows from the base, so new growth will be coming from there. Herbs also tend to do better when they are ignored. Water, yes. Light, definitely. Most plants that are taken inside have an adjustment period since they aren't getting as much light as they were outside. You can try to increase their light-- I like the new LED growth lights, but the old standbys work well, too.

    Be patient and judicious in the watering. If the mint goes to mint heaven then know that you can always try growing it from seed in the winter months.

    You can start acclimating plants before bringing them inside. Move them into a lower light area and cover at night to protect from chill. After a week move in inside but into a cooler room. Maybe a room that can be closed of and heat reduced for a few days. Gradually increase the heat. If you live in a humid climate the indoor air will be dryed out when the heat is turned on. In a wide tray place an upside down saucer to sit the pot on. Fill it with water and as it evalidates it will increase humidity.

    Did you plant it in a pot that was much larger than the space it was ? Plants will die trying to.put out roots and have no energy left for the above the ground part. Comments above are correct on watering less and lighting more. Green plants taken from outside sun need to acclimate to the lack of direct sun. Wash it. Watch it, water it sparingly.

    Gee, I never thought of this as a problem. I live in Utah, where we get heavy snow, and I have a whole planting bed full of mint--peppermint and spearmint both. The tops usually die back for about two months and then come right back. But mint is very eager to grow; it will take over the universe if you'll let it. Before you water, stick a finger into the soil at least one inch deep. If there's even slight moisture there, it's too early to water. Mint does love water, but not too much! I just live without fresh mint the months it's dormant. You can harvest whole plants and tie them together and hang them just about anywhere, hanging with the roots up and the leaves down. They dry nicely, smell great while drying, and are perfectly usable.
