How Much Sun Does Basil Need?

Basil is a popular herb that is easy to grow in your garden or even indoors.  One of the most important factors for growing healthy basil plants is providing them with the right amount of sunlight. In this section, we will discuss how much sun basil needs and what can happen if it doesn’t get enough or gets too much.

Can Basil Grow in Indirect Sunlight?

Basil can grow in indirect sunlight, but it may not grow as well as it would in direct sunlight.  If growing basil indoors, placing it on a sunny windowsill that gets at least six-eight hours of direct sunlight per day is ideal.

However, if you don’t have a sunny windowsill, you can still grow basil under fluorescent lights or in a location that gets indirect sunlight for at least six to eight full hours of sunlight per day. Ensure it can get the best morning sun rather than hot exposure in the afternoon.

Can Basil Grow in Shade?

Basil can grow in partial shade, but it may not grow as quickly or produce as many leaves as it would in full sun.  If you live in a hot, dry area, it may be better growing basil in partial shade to prevent wilting.  However, it is best to provide basil with at least six to eight hours of direct sunlight per day for optimal growth.

What Happens if Basil Doesn’t Get Enough Sun?

If basil doesn’t get enough sun, it may not grow as quickly or produce as many leaves as it would in full sun. The leaves may also be smaller and less flavorful.  If your basil is indoors, ensure to place it in a sunny location or provide it with artificial light to ensure it gets enough sun.

If you grow outdoors, ensure to plant it in a location that gets at least six or eight hours of direct sunlight per day. (Learn How Long Do Sunflowers Bloom)

Can Basil Get Too Much Sun?

Yes, basil can get too much sunlight. If basil gets too much, it may wilt or become stressed.  The basil leaves may be yellow or brown. If you live in a hot, dry area, it may be better to grow basil in partial shade to prevent it from getting too much sun.

If you are growing basil indoors, ensure to monitor the amount of sun it gets and move it to a shadier location if necessary. In summary, basil needs at least six- eight hours of direct sunlight per day for optimal growth.  Fresh basil planted grows in indirect sunlight or afternoon shade but may not grow as well. If basil doesn’t get enough hours of sunlight, it may not grow as quickly or harvesting basil leaves will deliver smaller yields.

Planting Basil

If you’re planning to grow your own basil here, you’ll must know how to plant it properly.

Here are some tips to help you get started.

When to Plant Basil

The best time to for your basil plant is after the last spring frost. This will give your plants enough time to grow and mature before the first frost of the fall.  If you’re not sure when the last frost is in your area, you can check with your local gardening center or extension office.

Where to Plant Basil

Basil prefers full sun, so it’s best to plant it in a location suitable for basil. Sunlight needs to be 6 hours per day. If you live in a hot climate, however, plant your aromatic herb in partial shade to protect it from the intense summer heat.

Basil thrives in moist, nutrient-rich soil. If you’re planting in the ground, ensure the soil is well-draining and has plenty of organic matter. If you’re planting the annual plant in a container rather than in ground soil, use a high-quality potting mix that is specifically formulated for basil growing in container gardening.

How to Plant Basil

To plant basil, follow these simple steps:

  1. Prepare the soil: If you’re planting in the ground, loosen the soil to a depth of 8-10 inches and mix in some compost or other organic matter. If you’re planting in a container, fill the container with a potting mix, leaving about an inch of space at the top.
  2. Plant the seedlings: If you’re using young plants, dig a hole that is slightly larger than the root ball and gently place the plant in the hole. If you’re using basil seeds, sprinkle them over the soil and cover them with a thin layer of soil.
  3. Water the plants: After planting, water the plants thoroughly to help them settle into their new home. Keep the soil moist but not waterlogged.
  4. Care for the plants: As your basil grows, ensure to keep the soil moist and provide enough hours of sun. You may also want to fertilize your plants every few weeks to keep them healthy and strong.

By following these simple tips, you can plant and grow healthy, flavorful basil in your in-ground or container gardens. (Learn How Much Sun Do Mums Need)

Tips for Growing Basil

If you’re looking to grow healthy basil, there are a few key things to remember. Here are some tips to help you get started:

Watering Basil

Basil thrives in moist soil, so it’s important to water it regularly. Aim to keep the soil evenly moist, but not waterlogged. You can check the soil moisture by sticking your finger about an inch into the soil. If it feels dry, it’s time to water. If it feels moist, hold off for a day or two.

Fertilizing Basil

Basil is a heavy feeder, so it benefits from regular fertilization. You can use a balanced fertilizer, like a 10-10-10 or 20-20-20 blend, every two to three weeks during the growing season. Alternatively, you can use a slow-release fertilizer at the beginning of the season. Be sure to follow the manufacturer’s instructions for application rates.

Pruning Basil

Pruning your basil regularly can help encourage bushier growth and prevent it from getting too leggy. When your basil plant has six to eight basil leaves, and you see a flower bud, you can pinch off the top two to three sets of leaves. This will encourage the plant to branch out and grow more leaves.

You can continue to pinch off the top sets of leaves every few weeks throughout the basil growing season, and pinching the bud keeps the plant growing.

Harvesting Basil

Regarding harvesting basil, it’s best to do it early in the day, before the sun has evaporated the plant’s essential oils. This will help ensure your basil has the best flavor and aroma. To harvest fresh basil now, simply pinch off the leaves with your fingers or use a pair of scissors.

You can harvest the leaves as soon as they are large enough to use, but be sure to leave at least a third of the plant intact so it can continue to grow. Harvest basil and mix it with olive oil to use or put in ice cube containers to freeze.

Growing Basil Indoors

If you want to grow basil indoors, you must pay attention to its specific requirements. Here are some tips to help you grow healthy basil plants indoors.

How Many Hours of Sun Does Basil Need?

Does basil need direct sunlight? Basil needs at least six hours of full sun each day to grow well. If you don’t have a sunny window, you can use fluorescent bulbs to provide the light for your basil sun requirements.

Keep the bulbs about 2 to 4 inches away from the top of the plants and ensure the leaves don’t touch the bulbs to prevent burning.

Temperature Requirements

Basil plants prefer warm temperatures between 70 and 80 degrees Fahrenheit. If the temperature drops below 50 degrees Fahrenheit, the plant may suffer damage. Keep the plant away from cold drafts and windows during the cold weather and winter months.

Soil Requirements

Basil plants grow best in moist, well-draining soil. Use aged compost enriched with nutrients to keep the soil fertile. You can also use potting soil mixed with perlite or vermiculite to improve drainage.

Watering Requirements

Basil plants need consistent moisture to thrive. Give the plant some water when the soil’s not moist. Don’t let the soil dry out completely, but also avoid over-watering, as it can cause root rot. Use a watering can or a spray bottle to water the plant gently.

To make watering easier, you can use ice cube trays to water the plant slowly and evenly. Fill the trays with water and place them on top of the soil. The ice will melt slowly, providing the plant with water.

Besides these requirements, basil plants also benefit from fresh air circulation. If you’re growing basil indoors, ensure to open the windows or use a fan to keep the air moving. If you’re using an airtight container, ensure to open it periodically to allow fresh air to circulate.

By following these tips, you can successfully grow basil indoors and enjoy fresh herbs all year round.
