How to Propagate String of Bananas (5 Easy Steps)

With its sleek banana-shaped leaves The String of Banana is a beautiful sight to see and an indoor plant that you will enjoy growing.

It’s likely to be simple and easy regardless of whether you’ve had bananas before or are an expert gardener. Each step I’m here to assist you.

A banana string grows easily in water and soil through stem cuttings. First, collect healthy leaves and then treat the roots by introducing rooting hormones. In order to get the cutting to grow you can either put it in water or soil. Make sure the plant receives plenty of sun during the first three to four weeks.

Why Should You Propagate Your String of Bananas?

There are two main reasons for propagating your banana string:

The most popular reason is to help save a dying plant. If your bananas suffer from root rot or have extensive root damage caused by cold or frost it could be the only option.

If all other options for rescue are unsuccessful, re-propagating bananas is an the ideal way to start from scratch and create new succulents.

Additionally, it’s generally simple and easy to reproduce this string of bananas. It’s due to its durability and tolerant of conditions that are near drought and its leaves do not drop easily. Additionally, their cuttings grow quickly.

It’s easy to grow the banana string. However, you must take good stem cuttings of the plant’s mother, then you’ll be able to have all the materials you need to begin an entirely new plant in your palms.

With their lush green foliage and light pink or white blooms, the banana plant make stunning to look at in their natural surroundings.

There’s no need to fret about adding tension to the gardening schedule by making copies of these stunning plants.

When Should You Propagate Your String of Bananas?

There are several aspects to take into consideration in responding to this question. The motivation behind why you wish to reproduce this plant will be the primary the light.

For instance, you should start propagating immediately if you’re propagating to keep a string of bananas that have root rot. If it’s autumn and you don’t want to put off propagating until spring.

If you are looking to increase the number of succulents you have it is important to prepare ahead. The best time to start propagating your banana string is when it’s flourishing and growing quickly.

It is usually the case in the summer and spring months.

Be aware that cuttings that are new will require 3-4 weeks to establish. Therefore you’ll have to plant them during warm months to decrease the risk of root rot, and also increase the chance of rooting.

In actuality I try to make it a habit to propagate my succulents (including the bananas) prior to when the growing season starts. In our region it is typically in the spring or early summer.

Another benefit of choosing this date is the fact that your parent plant won’t be afflicted with stress or shock because of taking multiple stem cuttings.

In addition, in order for the rooting cuttings to grow roots and flourish to grow, they require lots of indirect, bright light.

What You’ll Need

Fortunately, the process of propagating a string of bananas isn’t an energy-intensive job. However, for the majority of the time, gardeners will require the following tools:

  • A pair of disinfected, sharp pruning shears, snips or scissors (a sharp knife, sterilized, or sharp may suffice)
  • A container or pot that is between four and 6 inches wide. I highly recommend you make use of a terracotta or flat that has drainage holes at the bottom.
  • A potter’s mix that drains well It is possible to purchase an already-made batch of succulents or Cactus mix (Check the most current prices at Amazon right here).
  • Liquid rooting hormone or powdered (optional however I highly recommend it, particularly if you’re propagating into soil)
  • Bottled, filtered, also known as distilled or bottle water, is required when you plan to reproduce in water, or if your tap water is contaminated with excessive levels of chlorine/fluoride.
  • To shield your plant from insects, elements, other pests Wrap it in burlap or cheesecloth.

Ways to Propagate String of Bananas

Cuttings from stems are a simple method to grow the banana string. Some stem cuttings must be harvested in spring or early summer , and planted again.

If you wish to ensure that your succulents are alive for years to be it is the most effective method.

Based on what I’ve learned from my research to date, you can cultivate a banana plant in water or soil. But, even though you can plant your plant from seeds, this is not as effective.

I’ll show you two ways I can grow your banana string in two ways.

Option A: Stem Cuttings Propagation in Soil

I would rather propagate the banana string in soil since it is more convenient and less troublesome. Also, it is easier to observe the callus by reproducing the callus this way.

As we’ve mentioned it is necessary to disinfect your pruner, a pot that is suitable, and the potting mix. In addition it is recommended to follow these steps to grow your plant in soil.

Step #1- Taking Stem Cuttings

  • Cut a few good stem strands from the banana string.
  • The cut should be below the leaf node.
  • Each stem should be between 5 and 4 inches in length.
  • Take a couple of leaves of each cutting.

Step #2 – Allowing Calluses to Form

Before planting, you should leave each stem to cut for a few days or two. This will allow the to be plucked and the ends that have been cut to become rough and dry.

Step #3 – Prepping the Potting Medium

The pot you choose to fill with a potting medium that drains well. I like a cactus or succulent specific premix.

The container should be filled with water, and put it in a bathtub or sink. Let the container soak up water until it is saturated, and then let it drain to ensure that the container is dry but not sloppy.

Create a hole in the center of the pot. It should be at least 1 inch deep. this is the place where you’ll place your cutting stem.

Step #4 – Planting String of Banana Stem Cuttings

While it’s not required you can dip the cut ends of each stem in the rooting hormone. It will provide your new plant the head start it needs.

Cut the ends of each cut into the hole in the middle right away and make sure that all the leaves are over the line of soil.

Begin by gently patting the soil around the cut to ensure that it remains in the right place.

Step #5- Care and Maintenance

It is recommended to place the pot in a bright and well-lit space in case you are growing indoors. If the plants are outdoors, they’ll flourish in a shaded space.

Maintain the temperature between 65 degF and 75degF (18degC and 24degC)

Examine the soil for potting and water it if it appears dry throughout the day. Avoid excessive watering to avoid the degeneration of the tips of the cuttings.

Option B: Stem Cuttings Propagation in Water

It’s easy to grow the banana string in water with no special tools. All you require is a pair of clean pruning snips, a good stem cutting tool, and a glass or jar container.

  1. Find sturdy stems and cut them into four to five-inch cuttings. Cut cleanly above the leaf node using an abrasive, disinfected cutting tool.
  2. Take a few of the leaves that are left to prevent them from rotting.
  3. Put the stems into the glass container or jar immediately.
  4. Fill the glass to about halfway purified or distilled water. tap water could be contaminated with chlorine, fluoride, or other harmful chemicals.
  5. Set the glass container in a sunny space, but not directly in sunlight.
  6. It is recommended to do water changes every week to increase oxygen levels and stop the growth of microbial species.
  7. Thin, long roots that look like tendrils are expected to develop in the next few weeks.
  8. When the roots are plentiful and established, transfer the cutting that is rooted into a pot that is filled with a cactus that drains well or a succulent pots.

There is less chance of soil-borne fungi or bacteria that attack water-propagated bananas.

Here’s What I Did: The jar was filled up with the water, then wrapped it with Saran wrap. Make holes in the jar and then insert the cuttings. Within one week, all of my tiny cuttings had developed roots.

Problems You May Encounter While Propagating Your String of Bananas

Root Rot

A banana string should be fairly easy to propagate when it is propagated properly. However, excessive watering could cause a lot of problems for it.

Be on the lookout for signs of early root rot, like drooping leaves or yellowing leaves, as well as an unpleasant odor emanating out of the soil.

This is a frequent issue when it comes to succulents that are propagated in soil. But, it’s not so common when grown in water.

Another thing to watch out to look out for is poor drainage particularly the absence of drainage holes at the base of the dish. In the event that this happens, you should start by making a new terracotta dish with drainage holes.

The potter’s medium that doesn’t drain correctly could be the cause. Instead, you can use a sterilized mix of succulents or cactus mix.

In general, it is recommended to wait until the soil is somewhat dry before adding water. In fact, root rot is typically caused by over irrigation.

Additionally, you must wait for two days to let the callus heal completely before planting your stem cuttings into the soil. The risk of a fungal infection is to develop when you plant them too soon.

Sun Scorching

If you are indoors, place the newly-propagated banana string in a sunny area. Too much direct sunlight could harm the roots and leaves that the plant.

The soil will begin to harden and prevent the roots from growing, in the event that the potting medium dry out too fast.

Place it in a spot that receives indirect sunlight, and you’ll get an enlightened plant. For the first 2 weeks of growth, an moderately sun-lit place is ideal.

If you’re growing bananas outdoors ensure that you place them in an area which receives sunlight.

Taking Too Long to Take Root

In the ideal environment the stem cuttings should begin to develop within three to four weeks. Anything that is more than six weeks beyond the norm indicates that there is a problem.

Poor lighting, low temperatures as well as overwatering and root rot could all be cited as the causes.

It is essential to apply the rooting hormone even in the absence of one of the other. This will speed up and facilitate the process of rooting.

Pest Infestation

Pests like mealybugs, caterpillars, mealybugs and Aphids, even spider mites are a common problem for banana plants that are grown outdoors.

It is recommended to wrap the cut pieces with burlap, cheesecloth, or a nets to keep insects away!

However, fungus gnats could be a concern when you’re propagating indoors. They be able to feed on the roots below that soil’s surface. If you are able, apply an untreated soil mix that is free of fungus gnats as well as their eggs.

Does Your String of Bananas Have to Be Healthy to Propagate Successfully?

The simple answer is not. Propagation is the gardener’s most effective weapon in the battle against damaged or failing plants. A few or even a handful of healthy stem cuttings of the parent plant is all you need.

The mother plant doesn’t require good health. Only the cuttings used in root growth must be in good health.

But, time is an issue when it comes to growing the bananas in a string because of root rot or other problems. So, if the plant is not totally destroyed, it’s recommended to cut the stem in the early stages.

It is a good thing for you that it is recommended that you take a few of the stem’s lower leaves prior to cutting.

How Long Does It Take to Propagate a String of Bananas?

Since the banana string is slow to grow It could take three weeks or more to detect any indications of the growth.

But, there’s no need to worry about it. However the hormone that stimulates rooting can aid in speeding up the process of rooting and allow for the fastest propagation.

Coconut milk cinnamon, coconut milk, yeast extract or honey can be used as a natural alternative to roots hormone in the event that you are unable to find it.
