Collecting and Germinating Mint Seeds

Collecting and germinating mint seeds will ensure you will have this versatile plant wherever you move to without the cost of buying more plants.  As mint can be grown in pots it makes a wonderful present for friends without costing you anything but the price of the pot.

The seeds are collected from the dried flowerhead.  Mint will flower in the autumn (fall) with spikes of white, pink or mauve flowers.  Some varieties may flower earlier.

Time needed: 20 minutes.

Collecting and Germinating Mint Seeds

  1. Picking Mint Flowers

    Wait until the flowerhead has dried then snip off and place in a plastic bag.  If you leave the flowerhead on the plant too long it may release the seeds on the ground.  This may be a problem if you prefer to keep your mint in pots.

  2. Removing the Mint Seeds

    Next rub the dried petals between your fingers to dislodge the seeds.  They will be small round black seeds.  Remove the petals from the bag leaving the seeds in the bottom.Collecting mint seeds

  3. Planting the Seeds

    Fill a try with potting mix then water well.  Sprinkle the mint seeds over the top then cover lightly with seed raising mix.  You can make seed raising mix from potting mix with this guide.

  4. Germinating Mint Seeds

    Mist the top with water then keep moist in a sunny frost-free position.  Seedlings will emerge in 2 to 3 weeks.  Sooner in warmer climates. Transplant to their final position when an inch tall.

How to Store Mint Seeds

Store mint seeds in an airtight container in a cool dark place with low humidity.  Label with today’s date and the contents.  The seeds should be viable for 2 years but may last much longer than that.

Planting Mint

Be aware that mint can be invasive if planted out in the garden as it sends out runners under the ground.  It can be difficult to remove them all.  Mint is best planted in pots and looks pretty on a windowsill.

Mint prefers a semi shaded position but can take full sun if the soil is kept moist. It likes humus rich soil but will thrive in any potting mix. Try this guide to growing and using mint.

Gifting Mint Plants

Save money by visiting garage or yard sales for pots.  They can be painted with any leftover exterior paint you may have.  Finish with a coat of exterior varnish.  This is a great way of personalising a gift.

If you are using a small pot for a windowsill try tying ribbon or lace around the outside rim.  It can be glued on with multipurpose clear fabric glue.  Glitter glue can also jazz up a plain pot.
