Understanding the Basil Plant
Before exploring the growing timeline of basil, let’s first understand the plant. Basil belongs to the mint family, and there are numerous basil varieties, including sweet basil, lemon basil, and holy basil (tulsi), among others. The plant’s size varies depending on the variety, but most basil plants grow to a height of between 18-24 inches. Basil produces small, white flowers and has bright green, fragrant leaves that can be used fresh or dried.
Basil has been used for centuries in various cultures for its medicinal properties. It is believed to have anti-inflammatory and antibacterial properties and has been used to treat a variety of ailments, including headaches, coughs, and digestive issues.
Types of Basil
There are several types of basil with different growth habits. Sweet basil, for example, is the most commonly grown variety, and it is the one that most people are familiar with. Lettuce-leaf basil features large leaves and is a great option for pestos, Thai basil is perfect for bringing a unique flavor to Asian dishes, and purple basil has a distinctive color and is perfect for garnishing salads and other dishes.
Basil is also used in a variety of cuisines, including Italian, Thai, and Indian. It adds a fresh, herbaceous flavor to dishes and is often used in sauces, soups, and salads.
Ideal Growing Conditions
Before we answer the question of how long it takes basil to grow, it’s important to understand the ideal growing conditions for the plant. Basil is a tropical plant that requires warm weather, lots of sunlight, and moist soil. The ideal temperature for growing basil is between 68-86°F. If the temperature falls below this range, the plant may not grow as quickly or may not grow at all. Additionally, the soil pH should range between 6.0-7.5 for optimal growth.
Basil can be grown both indoors and outdoors, and it is a great herb to have in your home garden. When planting basil outdoors, it’s important to choose a spot that gets at least six hours of sunlight per day. If you’re growing basil indoors, place it near a sunny window or under grow lights.
When it comes to watering basil, it’s important to keep the soil moist but not waterlogged. Overwatering can lead to root rot, while underwatering can cause the leaves to wilt and the plant to die. To ensure that the soil stays moist, water the plant deeply once a week or more frequently if the soil feels dry to the touch.
Basil is a versatile herb that is easy to grow and adds a fresh, herbaceous flavor to a variety of dishes. With the right growing conditions and a little bit of care, you can enjoy fresh basil all year round.

The Growth Timeline of Basil
Basil growth takes time, and you need to exercise some patience during the process. The growing timeline for basil largely depends on the type of basil you are growing, the growing conditions, and other factors that we will discuss later in this article. Nevertheless, basil typically follows a four-stage growth process:
Germination Stage
The first stage of basil growth is the germination stage. During this stage, the seeds sprout and begin to develop roots. Germination typically takes about 5-10 days.
Seedling Stage
After the seeds have germinated, the next stage is the seedling stage, which lasts for about 2-3 weeks. During this stage, the plant develops its first set of true leaves, which are larger than the seed leaves and are essential for the plant’s growth and development.
Vegetative Stage
After the seedling stage, the basil plant enters the vegetative stage. This stage is characterized by rapid growth and development of the plant’s leaves and stem. The vegetative stage typically lasts for about 4-6 weeks.
Flowering Stage
The final growth stage of basil is the flowering stage. During this stage, the plant stops growing and begins to focus on producing flowers and seeds. The flowering stage typically occurs about 8-12 weeks after planting the seeds.
Factors Affecting Basil Growth
While the growth timeline for basil is relatively predictable, there are numerous factors that can influence how long the plant takes to grow. Some of the most significant factors that affect basil growth include soil quality, watering frequency, sunlight exposure, and temperature.
Soil Quality
The quality of the soil in which the basil is grown can significantly affect its growth rate. Basil prefers moist, well-draining soil with adequate nutrients. Soil that is too heavy and dense may not allow the plant’s roots to absorb water and nutrients effectively.
Watering Frequency
Basil requires regular watering to grow effectively. The frequency of watering, however, varies depending on the growing conditions. If the soil drains well, the plant may require more frequent watering, while if the soil holds water for longer, the plant needs less frequent watering.
Sunlight Exposure
Basil requires ample sunlight to grow vigorously. The plant thrives under full sunlight for 6-8 hours daily. Insufficient sunlight exposure can result in stunted growth, delayed maturity, or poor quality produce.
Temperature
As previously mentioned, basil requires a warm climate to thrive. If grown in an environment that is too cold or too hot, the plant may not flourish as expected. Temperatures below 50°F can cause the plant to wilt, while temperatures above 90°F can cause it to bolt quickly, resulting in poor quality vegetation.

Tips for Growing Basil Successfully
Now that you understand the basil plant and its growth timeline let’s explore some tips for growing basil successfully.
Choosing the Right Basil Variety
Choose the basil variety that suits your needs. For herb gardens, sweet basil is a great option, while for cooking ethnic dishes, choose Thai basil or lemon basil.
Proper Plant Spacing
Place the plants 8-10 inches apart in nutrient-rich, well-draining soil and ensure that each plant receives at least 6 hours of direct sunlight daily. Proper plant spacing and sunlight exposure facilitate plant growth.
Pruning and Harvesting Techniques
Prune the plants regularly to encourage growth and maintain their shape. Pruning a plant often results in a bushy plant with more leaves and less space between branches, promoting better yield. Harvest only a third of the plant at a time, so that the plant will continue to grow healthily and produce quality leaves.
Conclusion
How long it takes basil to grow varies depending on the growing conditions and the type of basil grown. However, by understanding the ideal growing conditions, the basil growth timeline, the factors that affect its growth, and the tips for growing basil successfully, you can grow healthy and flavorful basil plants in your garden or home. Happy Growing!
Basil FAQS
How fast can basil grow?
Basil growth depends on several factors such as the variety of basil, growing conditions, and other environmental factors. However, typically basil takes about 5-10 days to germinate, 2-3 weeks in the seedling stage, 4-6 weeks in the vegetative stage, and about 8-12 weeks in the flowering stage.
What is the fastest way to grow basil?
The fastest way to grow basil is to ensure that the plant has adequate sunlight, warm temperatures, and well-draining soil. Additionally, basil plants thrive with consistent moisture levels, so it’s important to water the plant deeply once a week or more frequently if the soil feels dry to the touch. Fertilizing the basil plant regularly with a balanced fertilizer can also help promote growth.
How long does it take to grow basil indoors?
Growing basil indoors can take slightly longer than growing it outdoors since indoor plants don’t receive as much sunlight and warmth as outdoor plants. However, with proper care, indoor basil typically takes between 6-8 weeks to mature.
Why is my basil growing so slowly?
Several factors can contribute to slow basil growth, such as insufficient sunlight, low temperatures, overwatering, and poor soil quality. It’s essential to ensure that the basil plant has adequate sunlight, warm temperatures, well-draining soil, and proper watering to promote healthy growth.
Why is basil so difficult to grow?
Basil can be challenging to grow if the plant doesn’t have the right growing conditions or if it’s exposed to pests or diseases. Basil requires warm temperatures, moist soil, and ample sunlight to grow effectively. Additionally, the plant is prone to pest infestations and diseases, which can hinder its growth and development.
Does picking basil make it grow more?
Picking basil regularly can promote growth and encourage the plant to produce more leaves. It’s important to prune the plant regularly to prevent it from becoming too leggy and to encourage it to grow more bushy. When harvesting basil, it’s essential to remove only a third of the plant at a time to prevent stunted growth and ensure that the plant continues to grow healthily.
