How to Clone a Mint Plant - A Step-by-Step Guide

Easy Instructions on How to Clone a Mint Plant

 

Cloning plants is a great way to propagate them. When you clone plants, you preserve their genetics, so if you have had a particularly successful harvest, or if you have a favourite variety of mint, then propagating that plant is a great idea. Whereas if you grow new plants from seeds from your plants’ vegetables or fruit, this leads to genetic variation, and there’s no guarantee the next generation of plants will have the same desired traits. In this article, we’ll cover everything you need to know about cloning mint plants.

 

One thing to keep in mind when cloning plants is that you should only take cuttings from healthy strong plants. Also, you should take a few more cuttings than required because sometimes not all of the cuttings survive.

 

How to Clone a Mint Plant

 

Equipment You’ll Need

  • Razor blade or scissors
  • Cup
  • pH balanced, distilled water, or filtered drinking water
  • Rooting hormone (I find gel or liquid to be more effective than powder)
  • A small plastic cup for rooting hormone
  • Rubbing alcohol

 

How to Clone a Mint Plant - Mint Cutting

 

Instructions

  1. Fill the cup halfway with filtered drinking water. You can also use distilled or pH balanced water.

  2. Choose a healthy parent plant to take cuttings from. Don’t take cuttings from diseased or wilting plants. The parent plant should have good, green growth and be large enough to take cuttings from.

  3. The best time to take cuttings from mint plants is late spring or early summer once the plants grow taller, but before they start flowering.

  4. You’ll need to take cuttings that are 3–5 inches (7.5–12.5 cm) long so that there is plenty of space on the stem for the roots to grow. Longer cuttings are easier to propagate than shorter ones, but there is no need to take really long cuttings—3–5 inches (7.5–12.5 cm) is enough.

  5. Sterilize your razor blade or scissors with rubbing alcohol and make a clean cut just below a node. Leave 2–3 nodes on the branch above the cut. Make sure to make the cut at an angle—this will help allow the cutting to root faster. Remove the lower leaves so that there is at least 2 inches (5 cm) of bare stem and only leave some leaves at the top to help the cuttings direct their energy towards producing roots.

  6. Now you need to dip the cutting into the rooting hormone. I find gel or liquid rooting hormone to be more effective than powder. This step is optional, but rooting hormone can help promote root growth, and I would recommend doing it. Dip the node end of the cutting into the rooting hormone. Tap off any excess hormone—too much can hinder the chances for successful rooting.

  7. Put the cutting into the cup with water and make sure at least one node is submerged.

  8. Keep the cuttings in a bright room with indirect sunlight. Mint cuttings don’t need too much sunlight or powerful grow lights because this can cause more leafy growth or even burn the leaves.

  9. The cuttings will drink water and some of it will evaporate, so you’ll need to replace it every week or as required. If you just top it off, this can cause algae and mold, so make sure to replace the water.

  10. Cuttings should develop roots in 3–4 weeks. Allow them to grow to at least 2–3 inches (5–7.5 cm) before moving them to a growing medium and putting them into your hydroponic system.
