Growing a big basil plant is a rewarding experience that requires attention to detail and the right conditions. To start, choose a pot that is at least 6-8 inches deep to give the roots room to grow.
Big basil plants prefer well-draining soil that is rich in organic matter, such as compost or manure. This will help prevent waterlogged soil and root rot.
Water your big basil plant regularly, but make sure the soil isn't too wet or dry. A good rule of thumb is to water when the top inch of soil feels dry to the touch.
Big basil plants thrive in warm temperatures between 65-75°F (18-24°C), making them a great choice for indoor gardens.

Growing
To grow a big basil plant, you'll want to provide it with the right conditions. One key factor is the heat and light where it grows. In the UK, a southern-facing conservatory with temperatures reaching 122 degrees F (50 degrees C) during peak season can be ideal.
To prevent the pot from sealing to the saucer, place several thin strips of wood in the bottom to elevate it a bit. This will help with watering.
You can also grow basil from nursery seedlings or cuttings. Choose a container with only a handful of young tender basil seedlings inside for the best results. A 6-pack of basil seedlings is even better.
To grow basil in a pot, choose one that's at least 6 inches deep and 6 inches wide for one to two basil seedlings. A bigger pot will limit the size of your basil plant as it matures, so use a larger one to plant multiple seedlings together.
Basil needs rich, well-draining potting soil and ample drainage holes. If you plan to keep the potted basil indoors, line the inside of the pot with porous landscape fabric to prevent the soil from running out.
For optimal growing conditions, place the pot in a location that gets at least 6 to 8 hours of direct sunlight. Basil can handle some afternoon shade in the hottest climates, but prolonged exposure to heat over 90°F will cause stress.

Here's a quick rundown of the ideal temperature range and sun requirements for growing basil:
- Temperature: 65 to 85°F (18 to 30°C)
- Sunlight: 6 to 8 hours of direct sunlight
- Shade: Some afternoon shade in the hottest climates
Remember, basil is not frost-hardy, and overnight temperatures below 50°F can cause stress. Keep an eye on the temperature and adjust your growing conditions accordingly.
Caring for Basil
To grow big, bushy basil plants, you need to provide them with the right conditions. Basil prefers consistently damp soil, but overwatering can lead to root rot, especially in cool conditions.
Water your basil plants when the soil just begins to dry out slightly, and use a moisture meter to check moisture levels. Keep the soil moist, but not too much or too little water.
Basil needs at least 6 to 8 hours of direct sunlight, but some afternoon shade can be beneficial in hot climates. To protect your basil from heat waves, you can use shade cloth or plant it between other taller plants that offer partial shade.

The ideal temperature range to grow basil is 65 to 85°F, and it's not frost-hardy, so be sure to protect it from temperatures below 40°F using frost cloth, cloches, or other protective covers.
Here's a quick guide to watering your basil plants:
- Water from below to force the plants to send down deep roots.
- Only water from above if the seedlings look wilted or the top inch of soil becomes crunchy and dried out.
- Let the plants use up all the water in the saucer before adding more.
- During the height of the growing season, basil plants can go through 1.5 to 3 gallons of water on hot days.
Tip #3: Watering
Watering your basil plants is crucial for their health. You want to keep the soil consistently damp, but not waterlogged. Overwatering can lead to root rot, especially in cool conditions.
Basil plants in containers dry out faster than those in raised garden beds or in-ground, so they need more frequent watering. To check moisture levels, use a moisture meter. This will help you determine when it's time to water your plants.
You should water your basil plants when the soil just begins to dry out slightly. If the top inch of soil becomes crunchy and dried out, it's time to water. Don't add more water until the plants have used up all the water in the saucer.

During the height of the growing season, in August through September, basil plants can go through a lot of water. On cool days, they may use around 1.5 gallons (6 liters) of water, while on hot days, they may use close to 3 gallons (12 liters) of water.
Here's a rough guide to help you estimate how much water your basil plants need:
Optimal Temperature and Sunlight for Growth
Basil loves warm conditions, and it thrives in temperatures between 65 to 85°F. This temperature range is ideal for basil growth.
To give your basil plant the best chance to grow, make sure it gets at least 6 to 8 hours of direct sunlight. However, some afternoon shade is beneficial in hot climates.
Basil is not frost-hardy, so it becomes stressed and stunted when overnight temperatures are consistently below 50°F. This is why it's essential to protect your basil plant from cold temperatures.
Here's a quick rundown of the optimal temperature and sunlight conditions for basil growth:
By providing your basil plant with the right temperature and sunlight conditions, you'll be well on your way to growing a healthy and thriving herb.
Pruning and Maintenance
Pruning is crucial to growing a big, bushy basil plant. Prune your basil plant when it's about 6 inches tall and has at least two to three sets of leaves.
Cut the stem back to the last set of leaves, leaving about a quarter of an inch of the stem above the last set of leaves. This will force the basil plant to keep branching out and growing bushier.
Pruning basil is a regular process, especially when you want to encourage a plant to grow wider and bushier. Prune every two to three weeks in the beginning, and later in the growing season, prune weekly to prevent the plant from flowering and going to seed.
To prune basil correctly, look below the first group of leaves at the top; you should find four tiny new leaves growing at the corners of the square stem. Snip the stem just above these new leaves using clean scissors.
A fresh viewpoint: Basil Plant Not Growing
Pruning the leaves from the top of the plant allows it to create two new branches from the spot that you picked. This process will grow the plant exponentially bigger every time you prune it.
Basil will naturally begin to flower as it ages, and to delay flowering and encourage more fresh leaves to grow, it's best to pinch off basil flowers soon after they form.
Here are some quick tips on maintaining basil as a shrub:
- Basil loves light, and grows best in full sun exposure. Do make sure the herb gets a minimum of 5-6 hours of direct sunlight every day.
- Regularly feed the plant to support its upward growth. Use a balanced liquid fertilizer, dilute it to 1/2 of its strength, and use it once in 6-8 weeks.
- Refrain from overwatering basil, and do it only when the topsoil feels a little dry to the touch.
Planting and Soil
Planting basil outside requires some careful consideration. Plant it in the spring after the risk of frost has passed, ideally when daytime temperatures are regularly in the 70s.
For basil to grow its best, it needs moderately rich, loose, well-draining soil. This means using potting soil amended with aged compost. If you have heavy clay soil, amend it with horticulture sand, compost, and/or potting mix to improve drainage.
Basil is prone to root rot when overwatered, so it's crucial to get the soil right. Adding worm castings and mycorrhizae to the planting hole can help reduce transplant shock and encourage healthy root development.

Harvesting and Uses
The big basil plant is a treasure trove of flavor and fragrance, and harvesting it is a breeze. Simply snip off the leaves with scissors or pinch them off with your fingers, and you're good to go.
You can harvest big basil leaves at any time, but the best flavor and aroma come from leaves that are harvested in the morning, after the dew has dried but before the heat of the day sets in. This is because the plant's essential oils are most concentrated at this time.

Harvesting
Harvesting is a crucial step in enjoying your basil plants. Regular pruning and harvesting encourages new growth, so use it to its full potential.
To harvest basil, cut stems just above a node, like you would when pruning seedlings. This promotes new growth and prevents the plant from becoming leggy.
Cutting too deeply on the main center woody stalk can be detrimental to the plant, so avoid it if possible. Leave a few sets of leaves behind per stem to allow the plant to recover.
Trimming a little from various areas at different heights encourages branching all over the plant. This is a great way to keep your basil bushy and full of new growth.
