Basil is one of the most beloved and widely used herbs in cooking; growing it at home not only ensures fresh leaves at your fingertips but also adds a touch of green to your environment.
Here's how to grow basil at home, from choosing the variety to harvesting its fragrant leaves and preserving them.
Choosing the basil variety
There are several varieties of basil, each with unique characteristics. Among the most common are:
- Genovese Basil: ideal for pesto, with large, fragrant leaves.
- Greek Basil: more compact, perfect for small spaces.
- Purple Basil: decoratively colored, great for adding color to your garden.
- Thai Basil: with a spicy flavor, used in Asian cuisine.
Preparing the space for basil
Basil is a plant that requires a lot of light.
It is crucial to place it in a location where it receives at least 6-8 hours of direct sunlight per day.
South-facing windows are the best, but if you do not have enough natural light, you can supplement with artificial lights specifically for plant growth.
Choosing the pot and soil
For growing basil, you need a pot that ensures good drainage.
Generally, a pot with a diameter of 15-20 cm is ideal for the growth of a basil plant.
Make sure, however, that the pot has drainage holes to avoid water stagnation.
As for the soil, use a quality, well-draining soil rich in organic matter.
You can opt for:
- Soil for aromatic herbs: specifically formulated for aromatic herbs to be light, well-draining, and rich in nutrients necessary for the healthy growth of these types of plants.
- High-quality universal soils: also suitable for basil, especially those that contain a good amount of organic material and are enriched with perlite or vermiculite to improve drainage.
Sowing and transplanting: step-by-step guide
There are two main methods to start growing basil at home:
From seeds
- Fill the pot with soil, leaving about 2 cm from the rim.
- Spread the basil seeds on the surface and lightly cover them with a thin layer of soil.
- Water lightly and cover the pot with a clear plastic to maintain humidity until germination.
- Remove the plastic when the seedlings emerge and place the pot in a bright area.
From seedlings
- Fill a pot with soil and make a hole in the center.
- Gently remove the seedling from its original container, being careful not to damage the roots.
- Place the seedling in the hole and cover the roots with soil.
- Water thoroughly to stabilize the plant in the new pot.
The secrets of proper watering
Basil requires regular watering so keep the soil constantly moist, but not soggy.
Check the soil with a finger: if the top 2 cm are dry, it's time to water.
However, avoid wetting the leaves as moisture can promote fungal diseases.
Fertilization: nourishing your basil
Basil benefits from light fertilization every 3-4 weeks during the growing season.
Use a balanced liquid fertilizer, following the manufacturer's instructions for dilution.
Be careful, though, with the amounts as an excess of fertilizer can be harmful.
Pruning and harvesting for lush growth
Regular pruning stimulates the growth of basil and prevents the plant from flowering prematurely, which could reduce the flavor of the leaves.
When the plant has reached at least 15 cm in height, you can start harvesting the leaves:
- Cut the larger and more mature leaves, starting from the top.
- Encourage lateral growth by cutting above a leaf node.
- Avoid removing more than a third of the plant at one time to avoid stressing it.
Recognizing and solving common problems
Even the most well-cared-for basil plants can encounter problems.
Here are some common issues and how to address them:
Yellow leaves: this issue can arise from either too much or too little water, or from a lack of nutrients. Check the soil and adjust the watering.
Aphids and other pests: if you notice small insects on the leaves, wash them with a solution of water and mild soap. You can also use a natural insecticide.
Fungal diseases: avoid wetting the leaves during watering and ensure good air circulation. If the plant shows signs of fungal infection, treat with an appropriate fungicide.
Storing and using basil in the kitchen
Harvested basil can be stored in several ways:
Fresh: place the stems in a glass of water and loosely cover them with a plastic bag, keeping them at room temperature.
Dried: hang the basil sprigs in a dark, well-ventilated place until completely dry. Once dry, crumble the leaves and store in an airtight jar.
Frozen: chop the leaves and freeze them in ice cube trays with a bit of water or olive oil. Alternatively, you can freeze the whole leaves.
Basil, as is well known, is incredibly versatile in the kitchen.
Here are some ideas to use it to its best:
Pesto: blend basil leaves with pine nuts, Parmesan, garlic, and olive oil for a delicious pasta sauce.

Beverages: add some basil leaves to water or cocktails for a fresh and unique flavor.
Growing basil at home is a rewarding and relatively simple activity.
Make sure to provide your plant with plenty of light, adequate water, and proper nutrition.
With time and practice, you'll find that growing basil is not only a way to always have this valuable herb at your disposal but also a way to relax and enjoy the pleasure of home gardening.
