Ever dream of having a basil plant that looks like a miniature tree, overflowing with fragrant leaves? You know, the kind that makes grocery store basil look a little sad and lonely? Well, my friends, that dream can become a reality!

I think a lot of people underestimate how easy it is to get basil to grow bushy. Sure, sunlight and water are important, but there are a few key strategies that can really take your basil game to the next level. I’m going to share some of my secrets, gleaned from over 10 years of writing about and (of course!) enjoying fresh herbs. By the end, you’ll be well on your way to harvesting a bushy basil plant that’s the envy of the neighborhood.

Start with the Right Basil Variety

If you want to learn how to get basil to grow bushy, it all begins with choosing the right kind of basil! You might not realize it, but there are dozens of basil varieties, each with its own growth habits, flavor profiles, and overall appearance. Some basil types naturally grow into compact, bushy plants, while others have a taller, somewhat leggy structure.

Popular Bushy Basil Varieties

Here are some excellent choices if your goal is a full, bushy basil plant:

• Sweet Basil: The classic Italian basil with large, flavorful leaves. A super versatile choice for culinary use.
• Genovese Basil: Specifically bred for pesto, this type has a slightly spicier flavor than sweet basil and also lends itself well to a bushy shape.
• Greek Basil: Forms a compact globe shape with small, intensely flavored leaves. Perfect for smaller containers or tight spaces.
• Lemon Basil: Offers a delightful citrus note alongside the traditional basil flavor. It grows bushy while having a bit more height than Greek basil.

Note: Regardless of the variety, always make sure you start with healthy basil plants or seeds from a reputable source. This ensures strong genetics, which contributes to overall plant health and bushiness.

The Secret is in the Pruning (and Pinching)

One of the most important things you can do to get your basil to grow bushy is to prune it regularly. I know it might feel counterintuitive to cut back a plant you want to grow but trust me, this is the key to fullness!

Why should I prune my basil?

• Stimulates Branching: When you cut off the top of a basil stem, you prevent the plant from putting all its energy into growing taller. Instead, it encourages the plant to branch out from the sides, leading to a bushier form.
• Prevents Flowering: Basil wants to flower and produce seeds. However, flowering redirects the plant’s energy away from leaf growth. Pruning delays flowering and keeps your basil focused on producing lush foliage.
• More Leaves to Harvest: A bushier plant means more leaves! Regular pruning increases your overall basil harvest throughout the season.

How to prune basil for bushiness

Here’s a simple guide:

1. Wait for the Right Time: Start pruning your basil once it has at least 6 sets of true leaves and is approximately 6 inches tall.
2. Locate the growth nodes: These are the little bumps along the stem where new leaves emerge.
3. Cut Above a Node: Use clean scissors or pruning shears to snip the main stem just above a growth node. Aim for a cut about 1/4 inch above the node.
4. Repeat: As the plant continues to grow, repeat this process on each stem, always cutting above a node.

Important: If you see flower buds forming, pinch those off as well to keep the plant focused on leaf production.

Provide Plenty of Sunshine

Basil is a true sun-worshipper! Understanding its light requirements is essential if you want to learn how to get basil to grow bushy.

How Much Sun Does Basil Need?

• Minimum of 6 Hours: Basil thrives in full sun, meaning it needs at least 6 hours of direct sunlight each day. Ideally, aim for 6-8 hours for optimal growth.
• Bright is Best: If you are growing basil indoors, a south-facing window will provide the most sunlight. Supplement with grow lights if needed. Find out more about how to care for basil indoors.

Signs Your Basil Isn’t Getting Enough Light

• Legginess: One of the most obvious signs of insufficient light is leggy growth. Stems become long and thin as the plant stretches toward the nearest light source.
• Small, Pale Leaves: Leaves may be smaller and lighter green than expected if the basil isn’t getting enough light.
• Weak Growth: A lack of sunshine results in an overall weak and spindly plant that won’t get as bushy as you desire.

Important Note: If your basil isn't getting enough light, move it to a brighter location or provide supplemental light. Remember, more light translates to more energy for the plant to promote dense, bushy growth!

Perfect Your Watering Technique

Proper watering is a delicate balance for achieving your dream of a bushy basil plant. Both overwatering and underwatering can hinder lush growth.

How Often Should I Water My Basil?

There isn’t a magic “every X days” answer to this question. The ideal watering frequency depends on factors like:

• Pot Size and Drainage: Smaller pots dry out faster than larger ones, especially those with good drainage.
• Climate and Weather: Basil growing outdoors in a hot, dry climate will need more frequent watering than a potted plant in a cooler environment.
• Soil Type: Well-draining soil will dry out more quickly than soil that holds a lot of moisture.

The Best Approach: Instead of a fixed schedule, check the soil moisture regularly. Stick your finger an inch or two into the soil. If it feels dry, it's time to water.

Overwatering vs. Underwatering Basil

Both can hinder bushy growth!

• Overwatering Signs: Yellowing leaves, drooping, root rot (which can be fatal). Learn the signs of overwatering and how to fix it here.
• Underwatering Signs: Wilting, dry, crispy leaves, stunted growth.

Best Ways to Water Basil

• Water Deeply: When you do water, thoroughly soak the soil until water runs out of the pot’s drainage holes. This encourages deep root growth.
• Water the Soil, Not the Leaves: Wet foliage can promote fungal diseases. Focus on watering at the base of the plant.
• Bottom Watering: This is a great technique to prevent overwatering. Place the pot in a tray of water and allow the soil to absorb moisture from the bottom up.

Give Your Basil Rich, Well-Draining Soil

The quality of your soil has a huge impact on how well your basil thrives. Knowing the ideal soil conditions and how to provide them is essential for achieving that lush, bushy growth you desire.

Ideal Soil Conditions for Basil

Basil flourishes in a soil that offers the following:

• Good Drainage: Basil hates soggy roots! Ensure the soil allows excess water to drain away easily. Learn more about the best soil for basil here.
• Rich in Organic Matter: Compost or aged manure enriches the soil with nutrients that support healthy basil growth.
• Slightly Acidic pH: Aim for a soil pH between 6.0 and 7.5 for optimal nutrient uptake for your basil. You can test your soil pH with a simple kit from your local garden center.

Best Soil Mixes for Basil

• DIY Blend: Combine equal parts potting soil, compost, and perlite or coarse sand. This provides a well-balanced mix perfect for basil.
• Commercial Potting Mix: Choose a high-quality potting mix specifically formulated for herbs that emphasizes good drainage.

Should I Fertilize Basil? (If So, How Often and With What)

While basil can do well in organically rich soil without added fertilizer, a light application of a balanced fertilizer every few weeks can promote healthy growth.

Tips:

• Organic Options: Fish emulsion or diluted liquid seaweed fertilizer are good choices.
• Avoid Over-Fertilization: Too much fertilizer can lead to excessive leafy growth at the expense of flavor and may make your plant vulnerable to pests.

Tips for Extra Bushy Basil

Beyond the core principles we’ve discussed, here are some valuable tricks to encourage maximum bushiness:

Plant Multiple Basil Plants Close Together

• Creates a Mini-Bush: Plant several basil seedlings (or multiple established plants) close together in a pot or garden bed. 
• Bonus: If you’re growing basil for culinary use, this gives you more to harvest from a compact space.

Harvest Frequently

• The More You Pick, the More it Grows: Regular harvesting is like regular pruning! Each time you cut leaves, it stimulates new growth, resulting in more branches.
• Don’t Be Afraid to Harvest: Afraid you’ll take too much? You can harvest basil quite heavily – aim to remove at least a third of the plant’s foliage when you need leaves. Learn the best time to harvest for maximum flavor and plant health.

Rotate Your Basil Crop

• Prevents Soil Depletion: Basil can use up specific nutrients in the soil. Rotate where you plant it each year, or refresh the existing soil with new compost, to maintain nutrient balance.
• Disease Prevention: Crop rotation can help reduce the risk of soil-borne diseases building up in one spot.

Companion planting can be beneficial! Basil makes a great neighbor for tomatoes, peppers, and other vegetables. Check out which plants help basil thrive and which might hinder its growth.

Troubleshooting Common Basil Problems

Even the most dedicated basil enthusiasts encounter problems from time to time. Learning to identify and address these challenges is essential for keeping your basil on track for bushy growth.

Pests and Diseases that Can Hinder Bushy Growth

• Aphids: These tiny sap-sucking insects can distort leaves and stunt growth. Learn how to get rid of them naturally.
• Downy Mildew: This fungal disease causes yellow patches and fuzzy growth on leaves. More information on how to identify and treat it here.
• Other Pests: Basil can occasionally attract whiteflies, spider mites, and other insects. Check out this resource for pest identification and treatment.

Why is My Basil Leggy?

• The #1 Culprit: The most likely reason is insufficient light. Your plant stretches and becomes thin when it’s reaching for more sunshine.
• Potential Fixes: Move the basil to a brighter spot or supplement with a grow light. Regular pruning can also help to counteract some legginess.

Why Are My Basil’s Leaves Turning Yellow?

• Possible Causes: Overwatering, underwatering, nutrient deficiency, or disease can all lead to yellow leaves. Here’s a guide specifically addressing this issue.
• Troubleshooting: Examine watering habits, soil moisture, and look for signs of pests or disease to diagnose the specific problem.

Important: For any disease-related issue, isolate the affected plant to prevent it from spreading to other healthy basil plants.
