How to plant basil seeds indoors? - Chef's Resource (2024)

Growing basil plants indoors can be a rewarding and enjoyable experience. Not only does the aromatic herb add a lovely touch to your cooking, but it also brings a touch of greenery to your living space. One of the easiest ways to grow basil at home is by planting basil seeds indoors. Here’s a step-by-step guide on how to do it successfully.

What You’ll Need:

– Basil seeds
– Seed starting trays or small pots
– High-quality potting soil
– Spray bottle
– Transparent plastic wrap or a seed starting dome

Step 1: Gather Your Supplies

Before you begin planting basil seeds indoors, make sure you have all the necessary supplies. You can find basil seeds in gardening stores or order them online. Seed starting trays or small pots are suitable for planting seeds, and high-quality potting soil will provide the best growing conditions for basil.

Step 2: Prepare the Seed Starting Tray or Pots

Fill the seed starting tray or small pots with potting soil, leaving about half an inch at the top for watering. Gently pat the soil down, ensuring it is evenly distributed.

Step 3: Plant the Basil Seeds

How to plant basil seeds indoors? Use your finger or a pencil to make small holes in the soil, about a quarter of an inch deep. Place one or two basil seeds in each hole and cover them with soil, lightly pressing on the top.

Step 4: Water the Seeds

How often should I water the basil seeds? Using a spray bottle, water the seeds gently. Keep the soil moist throughout the germination process to aid successful sprouting.

Step 5: Create a Mini Greenhouse

To maintain the necessary humidity for basil seed germination, either cover the seed starting tray with transparent plastic wrap or use a seed starting dome. This creates a mini greenhouse effect that helps retain moisture and warmth.

Step 6: Provide Adequate Light

How much sunlight do basil plants need indoors? Basil plants thrive in bright, indirect sunlight, so place your seed tray or pots in a location where they will receive at least six hours of sunlight each day. If natural light is limited, you can supplement it with a fluorescent or LED grow light.

Step 7: Wait for Germination

Within a week or two, you should start to see tiny basil sprouts emerging from the soil. At this point, remove the plastic wrap or seed starting dome to prevent excessive moisture and encourage air circulation.

Step 8: Thin the Seedlings

What does thinning mean? When the basil seedlings are about an inch tall, thin them by removing the weaker or overcrowded plants, leaving the healthiest ones to grow. This ensures the remaining plants have enough space to develop properly.

Step 9: Continue Care and Maintenance

What temperature is ideal for basil growth? Basil plants prefer temperatures between 65-85°F (18-29°C). Maintain these conditions and keep the soil consistently moist, but not soaked, by watering as needed.

Step 10: Transplant or Harvest

Once the basil plants have grown a few sets of leaves and are around four to six inches tall, you can transplant them into larger pots or directly into your garden if the weather permits. Alternatively, you can start harvesting the basil leaves for culinary use.

Step 11: Enjoy Fresh Basil All Year Round

With proper care, your indoor basil plants will continue to grow and provide you with fresh leaves throughout the year. Simply trim the leaves as needed for cooking, and the plants will continue to produce new growth.
