How To Propagate Peppers From Cuttings

There are many situations when you may want to clone your pepper plants. If you had a particularly successful harvest, or a highly disease-resistant plant, propagating that plant is a great idea.

By propagating peppers, you are preserving the exact genetics of the parent plant. Alternatively, saving seeds from your plant’s peppers and growing them out leaves room for genetic variation.

In this article, I’ll show you how to clone peppers from start to finish. The process is simple, but does take a long time, so plan accordingly!

Why Propagate Peppers?

I like the idea of cloning pepper plants for a few reasons, however it is not for everyone. There is nothing wrong with starting new plants from seed each year, as peppers can grow very large when started at the right time.

Pros:

  • Identical genetics
  • Avoid seed starting
  • Alternative to overwintering full plants
  • Can go directly to hydroponics

Cons:

  • Takes a long time to produce roots (~1-2 months)
  • Not always successful
  • Requires an actively growing plant

One great reason to try propagating peppers is to move soil-based plants into hydroponics. It is easy to take a small cutting and transfer it directly to a hydroponic system, without any messy soil.

Another possible reason to clone peppers is to avoid overwintering fully grown plants. With propagation, the risk of bringing in pests is greatly reduced, and there is no hassle with cleaning the roots.

Of course, if you are just propagating for the fun of it, that is a great reason, too!

Fun fact: The ‘Aloha’ pepper is a genetically unique plant that is cloned to preserve the striped appearance of its pods.


How To Propagate Pepper Plants

Keep in mind that cloning peppers is not always successful. It can take many weeks for a cutting to produce roots, so be sure to check on them regularly and change out the water as needed.

Tip: Move quickly to avoid the cuttings drying out – have your containers ready so that, once you make a cut, you can move the clones directly to fresh water.

Steps:

  1. Prepare a cup with water.

    Start by filling an opaque cup about halfway full with fresh water. Use filtered drinking water and be sure it is cool/room temperature.

  2. Identify a young branch.

    To increase your chances of a successful clone, always choose a branch that is actively growing. Avoid woody, stiff branches. Look towards the top of the plant for a medium sized branch that is still soft and green.Selecting branch for cutting - long growing branch that is not woody

  3. Make a clean cut at the base.

    Using a razor blade or very sharp pruning shears, cut the branch at an angle at its base. Never try to pinch or use dull scissors, as this can cause damage and reduce water uptake. Always use a diagonal cut to increase the wound’s surface area. This helps the cutting to take in more water.Stem cut end of pepper cutting

  4. Remove flowers, fruits & some leaves.

    To help it direct energy towards producing roots, remove all flower buds, fruits, and most of the foliage. Leave a few leaves (3-5) per cutting, but remove the rest.Trimming pepper cutting

  5. Submerge cut end in water.

    After cutting the branch, move it directly to your prepared cup of water. Some growers like to use rooting hormone to stimulate the plants to grow roots faster. If you plan to use this, dip the cut end of your branch in the powder before placing it in water. Some hormones can be dissolved in the water.Propagating pepper cutting in jar of water

  6. Keep in indirect light.

    Avoid too much direct sunlight or powerful grow lights. Instead, keep the cuttings in a bright room with indirect sunlight (a few feet from a sunny window or grow light works well). Too much light can cause more leafy growth or burned leaves.

  7. Watch for dried leaves.

    During the first few days, keep an eye out for wilting leaves. If you leave too many on the plant, they can become stressed. Remove a few more leaves in this case, but do not remove all the foliage.

  8. Replace water as necessary.

    Over time, the plant will drink the water and some will also evaporate. This can happen pretty quickly if it is dry. I like to replace the water every week or so, or as needed. If you just top off the water, it can be susceptible to mold and algae growth, so replacing it is preferred.

  9. Once roots form, transplant to soil or hydro.

    After a month or so, some cuttings may start to form small roots. Allow them to develop to at least 1-2 inches before moving to a growing medium.

You can easily clone several branches from the same plant, as long as they are healthy, actively-growing branches. Keep in mind that some pepper varieties will root much more quickly than others. It comes down to that individual plant’s physiology.


Growing Pepper Cuttings

Once you have successfully rooted your plant cuttings, you can plant them into normal potting soil, or into a hydroponic system. Gently spread the roots into loose potting soil and water thoroughly.

Place the pepper cutting under grow lights to promote healthy root development in the soil. Soon enough your pepper will be growing into a full blow plant!

Propagation tips:

  • Take multiple cuttings. To ensure the success of your propagated pepper, take multiple cuttings. Cloning peppers is not always successful, so having multiply cuttings will avoid wasted effort.
  • Choose branches that have several nodes. Nodes are points on the branch where new branches can form once the new cutting is established. Without enough nodes, the cutting may fail to form new leaves, or grow more slowly.
  • Try rooting hormone. If you want faster root development, add rooting hormone to the water. This is a plant hormone that “tells” the plant to form roots, rather than leaves or flowers.
  • Cover jar with aluminum foil. To avoid unwanted algae growth in the water, cover your jar with foil or a koozie to block out light.

When is the best time to propagate? i live in CT and wanted to save some of my peppers for next season.

I accidentally cut too much when trimming some of my plants. I had 2 cuttings to try and propagate. One used plain water and the other used my hydroponic nutrient with transition to bloom ratio. Plain water did not propagate as where the nutrient propagated with many thick roots. Thanks for the help.

May I plant my peppers deeper to encourage more rooting from the stems like tomatoes

No, it is not recommended. Peppers don't produce adventitious roots as readily as tomatoes, so plant at the same soil level when transplanting.
