To successfully clone a basil plant, you'll want to choose the right method - either cloning in water or soil. Cloning in water is a popular method, but it requires more maintenance and can be more prone to root rot.
To clone in water, you'll need to prepare a glass of water with a rooting hormone solution, then cut a stem from your healthy basil plant and submerge it in the water. This method is ideal for beginners.
Cloning in soil, on the other hand, is a more low-maintenance option that can produce similar results. You'll need to prepare a pot with a well-draining mix and a rooting hormone powder.

Preparing the Plant
To prepare your basil plant for cloning, start by selecting a healthy stem that's at least three to four inches long and doesn't have any seed stock or a crown.
Take your time to identify a good location on the stem to take the cutting from, ideally just below a leaf node.
Cut the stem at an angle of 45 degrees with a clean sharp knife or scissors, making sure to leave about a quarter of an inch just below the leaf node.
Cuttings that are too long can lead to a tall and leggy plant instead of a bushy one, so keep them between three to four inches.
Removing the lower leaves from the stem is crucial, so pinch off the leaves with your fingers or scissors, leaving only the top two sets of leaves.
Be gentle when removing leaves to avoid damaging the stem, as this can prevent the cutting from rooting.
Taking Plant Cuttings
To take plant cuttings from a healthy basil plant, select a stem that doesn't have any seed stock or a crown and is at least three to four inches long.
It's essential to cut the stem at an angle of 45 degrees just below a leaf node with a clean sharp knife or scissors.
Cuttings that are too long won't root well, so take them about a quarter of an inch below the leaf node.
Taking a couple of cuttings is a good idea, just in case one doesn't root.
Put the cutting in water, making sure the leaf nodes are underwater, and the lower leaves can find support on the edge of the container.
Using a glass bottle or any water-proof container works just fine, and it's a good idea to have the top leaves out of the water for fresh airflow.
A small plastic drinking bottle is a great option, and it's easy to check the development of the roots.
Make sure to cut no more than 1/3 of the plant at a time, as cutting too much can cause the plant to die.
Cutting under an angle of 45 degrees allows for a larger surface for roots to grow from, and roots will form at the cut and at the nodes.
Roots will usually form at the leaf node area, where the leaves are attached to the stem.
It's best to use tapwater at room temperature for rooting basil cuttings, and avoid cold water.
By cutting just below a leaf node, you'll increase the chances of successful rooting and new roots will be formed.

Rooting in Water
Rooting in water is a great way to propagate basil plants. It's a relatively simple process that requires minimal equipment.
To start, fill small glasses or mason jars with filtered or spring water. If using tap water, leave it out for 24 hours first so the chlorine can evaporate.
Take the prepared cuttings and place them in the water, making sure no leaves are underwater. This is crucial to prevent rotting.
Place the glasses or small jars in a spot with bright, indirect light. Change the water every few days to prevent bacteria or algae from growing.
You can expect to see little roots in about 10 to 14 days. I keep a spritzer filled with water nearby so that I can mist the cuttings daily.
When the roots are an inch or two long, remove the cuttings from the water and pot them up into a container filled with pre-moistened potting mix.

Transferring to Soil
You can transfer your rooted basil cutting into soil once the roots are about 2 inches (5 cm) or longer. This isn't an exact science, and some people even skip the water phase and stick the cuttings immediately into soil.
To prepare your soil and pot, use a medium size pot with a drainage hole, about 5 or 6 inches in diameter. Place a coffee filter in the bottom of the pot to prevent soil from escaping and making a mess.
You can also use larger pebbles in the bottom for this reason, but coffee filters are just as effective and lighter. Fill the pot about half full with your potting mix of choice.
To root basil cuttings in potting mix, you'll need a few supplies, including four-inch diameter pots, potting mix, and large clear plastic baggies or plastic plant domes.
Once you have your supplies, gently tease out the roots of your basil cutting so they cover more surface area in the soil. Make sure the soil is nice and loose, and set the rooted cutting on top of it, gently working some of the roots into the soil.

Here's a simple step-by-step guide to transplanting your rooted basil cuttings:
- Plant one rooted stem per pot to avoid overcrowding.
- Cover the entire root system and the two inches of leafless stem with soil.
- Water the transplants generously to jumpstart those roots into working and prevent them from drying out.
It's essential to keep the transplants in a sunny windowsill or use a grow light if needed. The bigger pot the bigger plant, so be prepared to have more basil than you can eat!
Troubleshooting
If your basil cuttings aren't rooting at all, check if you've followed the 7 steps to ensure success.
Basil will root in water easily, so try adjusting your technique and give it another shot.
You may have made a cut at the wrong place, not refreshed the water, or not had the right room or water temperature.
Roots can grow even in minor circumstances, so don't give up just yet.
If your basil cutting is dying after transferring it into soil, it might be due to the wrong soil mix or roots bruised or damaged in the planting process.

My Cut Dying in Soil
If your basil cutting is dying after transferring it into soil, it's likely due to one of two main issues: the wrong soil mix or roots bruised or damaged in the planting process.

You may have used a soil mix that's not suitable for basil, which can cause the cutting to struggle and eventually die. This is a common problem that has been mentioned by multiple herb gardeners.
Make sure to use a well-draining potting mix specifically designed for herbs like basil. This will help prevent waterlogged soil and root rot.
Alternatively, if you've already transferred the cutting into soil, it's possible that the roots were bruised or damaged during the process. This can cause the cutting to decline or even die.
Be gentle when handling the roots and avoid compacting the soil around them. This will help prevent damage and give your basil cutting the best chance to thrive.
Damaged Roots
Damaged roots are a common issue when transplanting basil cuttings. This is because the roots of the cutting and its smaller root hairs, which absorb water and nutrients, are very fragile.
To avoid damaging the roots, start by putting some soil mix in the bottom of the pot. Then, hold the cutting upright and fill the rest of the pot with soil mix, sprinkling it in with your fingers.

Pressing the soil hard into the pot and around the plant can cause damage to the roots. Instead, let the water drain through the holes in the bottom of the pot and avoid filling up the sink holes by pushing on the soil.
By handling the roots with care, you can minimize the transfer shock to the plant and help it establish itself in the new pot. This is especially important when transplanting from water to soil, as the rooted cutting was likely in a similar moist condition.

Planting and Growing
Planting basil cuttings in soil is a straightforward process. Simply put the rooted cuttings into a pot with soil or directly into the ground, covering with soil to above the root level.
Make sure the soil is moist, but not waterlogged, as this can cause the roots to rot. A good potting soil mix, like the one I use, can help prevent this.
It's essential to provide the young plant with enough water to adjust to the new growing medium, especially during the first couple of days. This will help prevent the plant from drying out.
The growth and speed of growth of the basil plant depend on the growing circumstances, including light quantity and quality, temperature, and more. The better the circumstances, the faster the plant will grow.

Position on a Warm Bright Spot
Positioning your basil plant on a warm bright spot is crucial for its growth and development. Basil prefers a comfortable warm spot, making a sunny windowsill an ideal choice.
Light is essential for plant growth, so choose a spot with plenty of light. Avoid direct sunlight if possible, but I haven't experienced any negative consequences from placing mine in full sun.
The better the growing circumstances, the faster your basil plant will grow. A warm bright spot will help it thrive and reach its full potential.

Planting
Planting is the next step in growing basil from cuttings. You'll want to prepare a pot with soil and gently place the rooted cutting into it, firming the soil around the stem to ensure good contact.
Fill your pots with moistened potting mix, gently firming it into the container without compacting it. This will give the roots of the basil cutting a good start.
To increase humidity around the cutting, place a clear plastic bag over the container or use a clear plastic plant dome. This will create a mini-greenhouse effect, helping the cutting to root and grow.
Keep an eye on soil moisture and water the cutting when the growing mix feels dry to the touch. Aim to keep the soil lightly damp, but not super wet.
Here's a summary of the steps to follow when planting your basil cutting:
It's essential to wait until the roots are about 2 inches long before transferring the cutting into soil. This will ensure that the roots have developed enough to support the plant.
Timing and Methods
Timing and methods are crucial when it comes to cloning a basil plant. The growth and speed of growth of the basil plant depends on growing circumstances like light quantity and quality, temperature, and more. The better the circumstances, the faster a basil plant will grow.
To transfer a rooted cutting into soil, wait until the roots are about 2 inches (5 cm) or longer. This isn't an exact science, and some people skip the water phase altogether.
You can root basil in two main ways: in water or in potting mix. For each method, you'll need basil cuttings. To take a cutting from a basil plant, clip a four to six inch long stem just below a leaf node, and at an angle to increase surface area for water uptake.
Here are the three methods of propagating basil:
- Divide Grocery Store Plants
- From Cuttings
- Sowing Seeds
Propagation Methods
To clone a basil plant, you'll want to learn about propagation methods. There are three main ways to propagate basil: dividing grocery store plants, rooting cuttings, and sowing seeds.
Dividing grocery store plants is a great way to start. You can simply take the plant out of its pot, separate the roots, and replant the individual sections. This method is easy and quick, but the resulting plants may not have the same flavor and aroma as the original plant.
Rooting cuttings is another popular method. To take a cutting from a basil plant, use clean garden snips or scissors to cut a four to six inch long stem. Clip it just below a leaf node and at an angle to increase surface area for water uptake.
Sowing seeds is a third option. This method allows you to start with a clean slate and grow a new plant from scratch. However, it can be slower and more labor-intensive than the other two methods.
Here are the three propagation methods in a nutshell:
- Divide grocery store plants
- Root cuttings
- Sow seeds
Remember to remove any leaves on the bottom third of the stem when taking cuttings to prevent rotting.
