How Long Does Basil Grow: A Complete Guide

Basil is a well-known herb that has been used for centuries due to its amazing flavor and medicinal properties. It is an easy-to-grow plant that can be grown in pots or in your garden. However, one question many people have when growing basil is how long does it grow before it needs to be replaced?

In this article, we will answer the question of how long does basil grow and other related questions such as what factors affect its growth time and tips on extending its lifespan.

Factors That Affect Basil Plant Growth

Several factors determine the growth rate of basil plants. These include:

  • Climate: The climate where you live determines how fast or slow your basil plant grows.
  • Soil quality: Your soil quality affects not only your plants' growth but also their lifespan.
  • Watering frequency: Overwatering or underwatering can damage your plants
  • Light Exposure: Exposure to sunlight enhances photosynthesis, which directly affects a plant's ability to thrive.

Now let's dive into the main topic – How long does Basil Grow?

How Long Does Basil Grow?

The average life span of a typical sweet Italian Genovese variety of basils ranges from 4 months up to 6 months before they start losing their vigor. This timeline applies both when grown in pots indoors or outdoors.

However, with proper care and attention, some species like Holy basil (also known as Tulsi), Lemon Basils (Lemon Sweet Dani), Cinnamon Basils (Cinnamon) may surpass six months which makes them ideal for farmers who practice greenhouse farming all year round.

Tips To Extend the Life Span Of Your Basil Plants

If you want your beloved herb at home for longer periods than usual here are some tips that will help keep them healthy;

  1. Prune regularly
  2. Use Fertilizer
  3. Water it correctly
  4. Provide appropriate light

Prune regularly

Pruning is critical to the health of basil plants, and it's essential that you remove dead or dying leaves regularly. Doing so will help improve air circulation, reduce moisture buildup around the plant and prevent diseases.

To prune your basil plant, locate the part of your stem where two leaves are growing parallel to each other at a distance from one another. Cut directly above these two leaves with a sharp pair of scissors.

Use Fertilizer

A well-fertilized Basil plant can thrive for an extended period. Before planting or during growing season fertilize your soil with organics such as aged manure (rich in nitrogen), compost tea which serves as an excellent source of nutrients for many herbs including basil.

Alternatively, you may use organic liquid fertilizer like fish emulsion which contains potassium (K) and phosphorus (P) essential in sustaining healthy root development thus extending their lifespans.

Water It Correctly

Watering frequency should be moderate; too much water can cause root rot while too little water causes stunted growth but remember overwatering kills faster than underwatering.

So how do you keep tabs on watering?

  • Check soil moisture levels by inserting your finger into about 2 inches deep.
  • Let them dry completely before watering again.
  • Avoid splashing water on foliage when watering since they are prone to fungal infections.

Provide Appropriate Light Exposure

Basil requires significant periods exposed to direct sunlight daily so having grown lights set up indoors can come quite handy especially during winter months when natural lighting is scarce – not forgetting that sufficient exposure also helps combat pests & diseases.


In conclusion, how long does basil grow depend on many factors such as climate conditions where planted quality soil used pragmatism in watering methods among others?

Sweet Italian Genovese varieties have average lifespans ranging from three-four months depending on how well you take care of them. However, basil plants can be extended beyond this time frame by using proper growing techniques like pruning, fertilizing correctly and adequate lighting.

By following these tips shared herein above, you will be rewarded with healthy-looking herbs that will last longer than usual.


How long does basil grow for before it is ready to harvest?

Basil is an annual plant, which means that it completes its entire life cycle in one growing season. The length of time that it takes for basil to mature and be ready for harvesting depends on a number of factors such as the variety, growing conditions and whether you want to harvest the leaves or allow the plant to flower. Generally speaking, most varieties of basil will take between 60-90 days from seedling stage until they reach maturity.

During this time period, you can expect your basil plants to go through several stages of growth including germination (5-10 days), vegetative growth where leaves are produced (4-6 weeks), bud formation (2 weeks) and finally flowering (~1 week). If you plan on using your basil primarily for culinary purposes then it’s best harvested during the vegetative stage where more foliage can be harvested per cut. On average, once established with optimal growing conditions such as consistent watering and warm temperatures around 70°F -80°F , Basil crop will grow up to about 12 inches tall before being ready for harvesting.

Can I continue harvesting from my Basil after I’ve already picked some leaves off?

Yes! In fact if properly managed by regular pruning/harvesting method ,the continuous removal encourages new growth throughout its whole lifespan.. Frequent cutting keeps your plant producing more foliage instead of focusing energy into flowering/seed production . It’s important though not overdo pruning or taking too much leafage at once so as not stunt further growth.

When picking individual leaves make sure cut right above a leaf node rather than snipping mid-way down a stem which can leave open wound leading weaker stems susceptible diseases caused by bacteria/fungi..

In summary frequent harvesting stimulates bushy bushier healthy grown while leaving enough foliage help sustain photosynthesis thereby keeping plants alive longer

What kind soil do Basil prefer?

Basil requires a well-drained soil with a pH level ranging from 6.0 to 7.5 . Soil’s texture must also be sufficiently aerated and loamy with good organic matter content as basil plants do not favor soil that is too compacted or waterlogged.

One can invest in potting mix specifically formulated for growing herbs, as this generally has the right mixture of nutrients and ingredients such as perlite , vermiculite etc.. Basil grows best in soil that is rich in organic matter to provide ample nutrients required for growth

If planting Basil directly into garden beds it’s worthwhile incorporating compost/manure/organic fertilizers prior planting -otherwise adding liquid fertilizer during the growing season will help boost foliage production.

How often should I water my Basil?

Basil requires regular watering so plan on keeping your soil moist- but never over-saturated.. The frequency depends on temperature/humidity levels ,soil moisture conditions etc, but typically basil needs consistent watering every two-three days.

It's important when irrigating your plant to avoid getting leaves wet which can encourage fungal diseases like powdery mildew. If possible try using drip irrigation/soaker hoses rather than overhead sprinklers or hand-held spray attachments.
Establishing mulch layer (like hay/grass clippings) helps conserve moisture by slowing evaporation from topsoil while simultaneously moderating temperatures around root zone area .

During dry periods where optimal humidity levels cannot be maintained consider placing a small humidifier near by since providing enough humidity really helps keep healthy looking foliage

Can I grow Basil indoors?

Yes! In fact indoor gardening is great way ensure year-round herb supply especially if one lives far North/South regions where frosty winter months may limit outdoor crop yields

When selecting an indoor location make sure there are at least six hours of adequate light daily — either natural sunlight or artificial light source preferably fluorescent grow lights sun can burn leaves so it’s important to keep your plant away from direct sunlight.

Lastly, make sure your pot has good drainage and soil is sufficiently aerated otherwise excess moisture will cause root rot. It’s also recommended to use a container with diameters that range from six to eight inches with minimum of 6 inch depth is sufficient for the basil plant root system. Additionally, you could add compost/manure in moderation into soil mixture for that additional nutrient boost.
With proper care and attention, Basil planted indoor should yield same leafy greens compared outdoor crops
