Rooting Basil Cuttings in Water

Basil is a popular herb that can easily be grown from cuttings. Rooting basil cuttings in water is an easy and effective way to propagate new plants, with the process taking two to four weeks.

With the right environment, basil cuttings can develop roots in as little as seven to ten days. To ensure successful rooting, it is important to provide plenty of humidity and bottom heat while keeping the cuttings in a bright location.

To begin, remove the top 4 to 6 inches of a basil stem or branch. If there are any leaves on the stem, remove them from the bottom 2 inches. Place the cuttings in a glass of water and position it in a bright location away from direct sunlight. It is fun to watch the roots grow in clear glass, but it is not necessary.

Preventing Basil Cuttings from Rotting

Unfortunately, sometimes basil cuttings do not root in water. There can be a variety of reasons for this, including rot, lack of light, heat or humidity. If the leaves are left in contact with the water or plastic container, they can easily become infected and begin to rot. To prevent this from happening it is important to keep the leaves out of contact with any moisture. Additionally, pay attention to how often you refresh the water and make sure it is kept clean and free from bacteria build-up that could lead to root rot.

Pinching Off Basil Flowers and Collecting Seeds

When basil plants flower, it is important to pinch off the flowers. This will help keep the plant growing and producing new leaves that can be harvested for cooking. The flowers are also quite lovely and make a great addition to tiny bud vases in your kitchen. To pinch off the flower buds, simply snip them off at their base with scissors or pruning shears.Harvesting some of the basil leaves for pesto is another way to encourage growth and keep your plants healthy. Half of the plant can be harvested without damaging its overall health; however, make sure not to overharvest as this could stress out the remaining foliage. Additionally, when harvesting basil leaves it is important to do so gently so as not to damage any of its delicate foliage.

Once the basil flowers have been removed, it is time to collect the black basil seeds. Black basil seeds are very small and therefore a fine colander should be used to collect them. After cutting off the brown and spent flower heads, allow them to dry for a few days in a warm, dry environment. Using a colander, crush the heads and remove any old petals or chaff that may have accumulated during drying. Basil seed collecting is surprisingly easy with this method.

Though basil leaves are not as delicious after flowering, they are still safe to eat. The flavor may be milder or more bitter than a younger plant, but it is still edible.

To maintain the best flavor, it is important to prune the flowers from the stems before they dry out and go to seed. If allowed to mature into seeds, basil will taste very bitter.

Growing Basil Cuttings in Water

When it comes to growing basil, there is a third option besides rooting cuttings in soil or water. It is possible to keep basil in water forever. This method involves filling a jar with clean water and placing the cutting into the jar so that only the leaves are above the surface of the water. To ensure success, mix 1 gram of balanced fertilizer such as N-P-K 20-20-20 with 1 liter of water and add this elixir to the basil growing jar. The fertilizer will help provide essential nutrients for successful growth and should be changed every two weeks for optimal results. Once rooted, you can transplant your new plant into soil or continue keeping it in just plain old tap water!

When it comes to watering your basil, the answer is simple – keep it moist. Basil requires 1 inch of water every week to remain hydrated and healthy. Water deeply at least once a week in order to reach the roots and maintain moisture levels. If you are growing your basil in containers, you may need to water more frequently as containers tend to dry out faster than soil beds.

To get started, cut the basil stem to a length of 3-4 inches and remove the leaves from the bottom two inches of stem. Place the stems in a jar filled with water and place it on a windowsill where it will receive plenty of sunlight. It should take about two weeks for roots to begin forming, at which point you can add fresh water if it gets cloudy.

Once the roots have grown to about 2 inches (5 cm.), you can plant your basil cutting in a pot.

Herbs like basil, mint, oregano, chives, parsley and thyme are all suitable for growing on a windowsill.

Growing Basil from Seeds – Tips and Tricks

Germinating basil seeds is another way to propagate new plants. To begin, fill a sterile seed starting medium with soil and water until moist. Plant 2-3 basil seeds per cell or pot, planting them 1/4 inch deep and firming the soil over the seeds well. The trays or pots should be kept warm (between 75°F and 85°F) and moist until germination occurs, which should occur in about 5-7 days under ideal conditions. It is important to remember that it can take up to two weeks for some varieties of basil to germinate so do not despair if you don’t see any sprouts right away! Additionally, when watering your basil it is important not to overwater as this could lead to fungal diseases such as damping off.

Although it is not necessary to soak basil seeds before planting, soaking them in warm water overnight will give them a good start and facilitate germination. To do this, place the seeds in a bowl or cup of warm (not hot) water and let them soak overnight. The next morning, drain off any excess water and plant the seeds according to the instructions above.

When it comes to growing basil, the most important factor is sunlight. Basil needs a sunny location that gets at least six to eight hours of bright light per day in order to thrive. It is best to plant basil in well-drained soil and water regularly, making sure not to overwater as this can lead to fungal diseases.

The signs of overwatering look similar to underwatering and include yellow leaves at the base of the plant as Basil leaves droop and wilt. Water should not be placed in a saucer beneath a potted plant.

It is not recommended to plant seeds or plants until the soil is warm (65 to 70 degrees) and the weather has settled. The ideal time for starting basil seeds indoors is 3-4 weeks before planting time. Once the soil has warmed up and night temperatures remain consistently above 50 degrees, you can transplant seedlings outdoors.

When it comes to surviving winter, basil does not do well in cold temperatures. Although temperatures close to 50°F will not kill your basil, the cold may cause the leaves to blacken. Any temperature below 45F is a danger zone and could cause permanent damage or death of your plants. We have so much sunshine in the summer that it’s the only reason I thrive outdoors in Alaska.

Water or Soil Propagation for Basil Plants

When propagating herbs and plants, you can choose between water propagation or soil propagation. Both are easy and will yield good results. When propagating in water, it is important to leave at least four leaves at the top of the plant by removing leaves from the lower half of the cutting. This will allow for maximum energy to be transferred from the existing stem to help jumpstart root growth.It is also important that when using a glass vessel for rooting cuttings in water, that it has enough room for new roots to grow without becoming too crowded. Additionally, pay attention to how often you refresh the water and make sure it is kept clean and free from bacteria build-up that could lead to root rot.If your basil cuttings do not take off in water after two weeks, don’t give up! Soil propagation may be worth trying as well; however keep in mind that soil can contain fungal pathogens which could infect your cuttings if they are not treated properly first with fungicide or hydrogen peroxide solution (3% H2O2).

Does basil grow better in water? The answer is yes, especially during the winter months when you don’t have to worry about soil conditions. Unfortunately, these cuttings were only made available for a limited time so it’s not clear how long they will remain available.

One way to keep basil fresh is to simply store it in a jar or glass of water, covered with a plastic bag, and treat it like a flower bouquet. Works like a charm!

When it comes to watering basil, the answer is not as straightforward. Smaller pots may need to be watered every day, while larger pots with compost may only need to be watered once a week. Smaller pots need to be watered more frequently than larger ones, and Basil growing in a pot needs to be watered more frequently than basil growing in the ground.

You should water your basil according to the natural elements of your garden, such as the sun and rain. Basil plants only need water for 3 to 4 days in the garden. If you’ve had steady rain events, it could be even longer. In contrast to peat-based potting mixtures, garden soil tends to hold moisture better.


Basil is a resilient herb that can be grown in water, soil, and in containers. The most important thing to remember when growing basil is to ensure that it is getting enough light and water. Basil prefers warm, sunny days, and should be kept in temperatures above 45F. Keeping the soil moist and trimming the flowers before they dry out will help the basil remain flavorful. To propagate basil, it is best to use water or soil propagation, and make sure to remove the leaves from the bottom 2 inches of the stem. Basil cuttings will root within 7-10 days, and should be ready for repotting in two to four weeks. With the right amount of warmth, sun, and water, you can enjoy the aromatic leaves of this tender annual for years to come.
