OK, we’re getting hungry, but the point is it’s a versatile herb to use in cooking and making aromatic oils. No wonder it’s one of the most popular herbs grown indoors and an excellent plant for beginners.

Technically known as Ocimum basilicum, Basil is a fragrant warm-weather plant that is easy to grow. It originated from India, and it’s a member of the mint family. The most common type of Basil is Sweet Basil. Growing Basil indoors is quite different from the usual care guide of growing Basil outdoors. It will require fertilizing, a healthy pH level, lots of sunlight, and the proper soil type.

Fun Fact: Basil is a rich source of vitamins A, B6, C, and K. It’s also a great source of minerals such as iron, manganese, and magnesium. 



One thing you should know that since Basil is an annual (a plant that has a life cycle of one year), it grows extremely quickly. It would only take 3 to 4 weeks for a Basil to grow from seed to harvest. Additionally, it requires frequent repotting. Every part of the plant is edible, from its glossy leaves and spikes of white flowers.

Learning how to plant Basil is pretty simple, considering it’s one of the easiest herbs to grow. Here’s everything you need to know to grow Basil in pots from seed.

Materials Needed:

  • Basil Seeds
  • Seed Starting Mix
  • Spray Mister
  • Starter Pots
  • Starting Container With Plastic Dome

Step 1: Prepare your starter pots by adding a slightly moistened seed starter mix to about ½ to 1 inch below the top of your container.

Step 2: Add Basil seeds to each pot. It’s best to place a few extra seeds in the center of your pot and to each pot so that you can choose the strongest plants once it sprouts. The reason behind this is some seeds won’t grow.

Step 3: Cover seeds with a thin layer of dry seed starter mix, approximately ¼ inch.

Step 4: Gently water your Basil seeds.

Step 5: It’s important to control humidity. It’s recommended to keep a humidity level between 40–60%. To do this, place your Basil in a shallow pan and plastic wrap. You can also use a specialized plastic starting container with a plastic dome.

Step 6: Basil is a warm-weather annual, place it in a warm location where the temperature is between 80–90°F.

Step 7: After 7 to 10 days, you will notice that Basil seedlings begin to emerge. Remove it from the plastic wrap and place the pot in a sunny area. Continue to keep the soil moist with frequent misting. Once it produces leaves, it’s time to choose the strongest seedling in each pot. These seedlings will be your main Basil seedling.

Step 8: Wait until your Basil seedlings are at least 3 inches tall with two sets of true leaves before transplantation. You can feed your plant with a weak fertilizer solution to boost nutrition.

Basil Plant Care Tips

When growing Basil indoors, it’s important to consider the lighting since this plant requires at least six hours of full sunlight each day. You can use fluorescent lights to grow your Basil, but it will need about 10 hours of light every day for healthy growth.

As we have mentioned that to encourage new growth, you should harvest your Basil plant more often. To do this, simply pinch off the stem right above where a pair of leaves are growing. Make sure to cut off several inches, approximately 6 to 8 inches. It’s also advised to handle it delicately so as not to bruise and blacken the leaves. Eventually, two more stems will start to grow, which means twice the leaves next time you harvest.

In case you end up with too much Basil, which is unavoidable, you can freeze it. To do this, puree leaves in a blender or food processor. You can add water as needed to make a thick puree. Then, pour the puree into ice-cube trays and freeze. You can use it within five months. Another alternative to store Basil is to dry them out by hanging upside-down in a cool, dark, and dry location, but this technique won’t guarantee that its flavor will be the same.

Here’s a detailed explanation of how to care for your Basil plant, from sunlight requirement to common problems and its solutions.


First, on our list on how to care for your Basil plant is to put it in a location where it can get at least 6 to 8 hours of full sun every day. It can also grow fluorescent lights, but it will need about 10 hours of light every day for healthy growth.

Remember to only water the plant when the soil doesn’t feel wet 1 inch down.

Common Problem: If the leaves of your Basil plant are turning yellow, this could mean that you are overwatering your plant. If the leaves of your Basil plant are turning brown and wilting, this could mean that you are underwatering your plant.

Solution: Overwatering or underwatering your Basil plant deprives it of oxygen. It could also cause the leaves to droop and fall off. To check if you are overwatering your plant, check if the soil is wet. If it is, then your Basil plant is receiving too much water. If the tip of the plant feels dry to the touch and it breaks off if bent, your Basil plant needs more water.

Remember to follow the recommended amount of fertilizer and schedule to avoid fertilizer burn or plant burn.

Pests & Other Problems

Drooping leaves in your Basil plant can indicate diseases and insect infestations, such as aphids, cutworms, mites, and whiteflies.
