The Ultimate Guide: Best Way to Grow Basil Outside
Basil, that fragrant herb we all love, is a surprisingly easy plant to grow, especially when you understand its needs. The best way to grow basil outside involves selecting the right spot, preparing the soil properly, and providing consistent care. We'll cover everything from choosing the right basil variety to protecting your plants from pests and diseases. This guide is your complete resource for growing healthy, flavorful basil outdoors.
Choosing the Right Basil Variety for Outdoor Growing
Not all basil varieties are created equal, especially when it comes to outdoor cultivation. Some are more resistant to pests and diseases, while others are better suited to specific climates. Understanding the different types will help you pick the best basil to grow in your area.
Popular Basil Varieties for Outdoor Gardens:
- Sweet Basil: The most common type, perfect for Italian dishes. It's relatively easy to grow and offers the classic basil flavor.
- Genovese Basil: A classic Italian basil prized for its intense aroma and flavor, ideal for pesto.
- Thai Basil: Distinct anise-like flavor, great for Asian cuisine. It tends to be more heat-tolerant than sweet basil.
- Lemon Basil: Offers a citrusy aroma and flavor, adding a unique twist to salads and sauces.
- Purple Basil: Adds color and a slightly different flavor profile to your garden and dishes. It's also often more ornamental than other varieties.
Consider Your Climate:
Before choosing your variety, think about your local climate. If you live in an area with hot summers, Thai basil might be a better choice than sweet basil. Similarly, if your summers are short, you might want to start your basil indoors to give it a head start. Look for basil varieties that are specifically labeled as "disease-resistant" or "heat-tolerant" if you live in an area prone to those problems.
Preparing Your Garden for Basil Plants
Proper soil preparation is crucial for the best way to grow basil plants. Basil thrives in well-draining, fertile soil with a slightly acidic to neutral p H (around 6.0 to
7.5). Let's delve into the key steps.
Selecting the Ideal Location:
Basil needs at least 6-8 hours of direct sunlight per day. Choose a location in your garden that receives plenty of sunshine. Avoid areas that are shaded by trees or buildings for most of the day. Also, consider the wind. Basil plants can be susceptible to wind damage, so a sheltered spot is ideal. If you're planting in containers, you'll have the flexibility to move them around to maximize sunlight exposure.
Soil Amendments for Basil:
Amend your soil with compost, aged manure, or other organic matter to improve drainage and fertility. Adding these amendments will help the soil retain moisture while still allowing excess water to drain away. Good drainage is essential to prevent root rot, a common problem with basil. Till the soil to a depth of at least 12 inches to loosen it up and incorporate the amendments evenly. Consider using a soil testing kit to determine your soil's p H and nutrient levels. This will allow you to tailor your amendments to your specific soil conditions.
Planting Basil Outdoors: Seed vs. Seedling
You can grow basil from seed or transplant seedlings. Each method has its advantages and disadvantages.
Starting Basil from Seed:
Starting basil from seed is cost-effective, but it requires more patience. Sow seeds indoors 6-8 weeks before the last expected frost. Use a seed-starting mix and keep the soil moist. Once the seedlings have developed a few sets of true leaves, they can be transplanted outdoors after the danger of frost has passed. You can also direct sow seeds outdoors after the last frost, but germination rates may be lower. When direct sowing, plant seeds about 1/4 inch deep and thin the seedlings to about 12 inches apart.
Transplanting Basil Seedlings:
Transplanting seedlings is a quicker way to get started. Choose healthy-looking seedlings with sturdy stems and green leaves. Harden off the seedlings by gradually exposing them to outdoor conditions for a week before transplanting. Plant the seedlings 12-18 inches apart in well-prepared soil. Water them thoroughly after planting. Be sure to gently loosen the roots of the seedlings before planting to encourage them to spread out and establish themselves in the soil. Avoid planting too deep, as this can lead to stem rot.
Caring for Your Outdoor Basil Plants
Once your basil plants are established, proper care is essential for a bountiful harvest.
Watering:
Basil needs consistent moisture, especially during hot weather. Water deeply when the top inch of soil feels dry. Avoid overwatering, which can lead to root rot. Morning watering is ideal to allow the foliage to dry before nightfall, reducing the risk of fungal diseases. Consider using a soaker hose or drip irrigation system to deliver water directly to the roots. Especially during those hot summer days, you will want to make sure your plants are well hydrated. For optimal watering and preventing leaks, consider using a qualitygarden water hose that is both durable and easy to use. The 75 FT Garden Hose with 10-Function Nozzle, featuring leak-proof metal connectors and a kink-free design, could be a reliable choice for maintaining your garden's hydration.

Fertilizing:
Basil benefits from regular feeding with a balanced fertilizer. Use a liquid fertilizer every 2-3 weeks or apply a slow-release granular fertilizer at planting time. Avoid over-fertilizing, as this can result in leggy growth and reduced flavor. Look for fertilizers specifically formulated for herbs, as these tend to have a lower nitrogen content. You can also use organic fertilizers such as compost tea or fish emulsion.
Pruning and Harvesting:
Pruning and harvesting are crucial for encouraging bushier growth and preventing your basil plants from flowering. Pinch off the top sets of leaves regularly to promote side branching. Once the plant reaches about 6 inches tall, you can start harvesting leaves. Harvest by cutting the stem just above a set of leaves. This will encourage new growth from those points. Remove any flower buds as soon as they appear, as flowering will reduce the flavor of the leaves. Harvest frequently to encourage continuous production.
Pro Tip: Don't discard the stems you cut! They can be used to make basil-infused oil or vinegar.
Protecting Basil from Pests and Diseases
Basil, like any plant, can be susceptible to pests and diseases. Here's how to protect your plants.
Common Basil Pests:
- Aphids: Small, sap-sucking insects that can cause yellowing and distortion of leaves. Control them with insecticidal soap or a strong jet of water.
- Slugs and Snails: These pests can chew holes in the leaves. Use slug and snail bait or handpick them off the plants.
- Japanese Beetles: These beetles can skeletonize the leaves. Handpick them off the plants or use a neem oil spray.
Common Basil Diseases:
- Downy Mildew: A fungal disease that causes yellow spots on the upper leaves and a gray, fuzzy growth on the undersides. Improve air circulation and use a fungicide if necessary. Choose disease-resistant varieties whenever possible.
- Fusarium Wilt: A soilborne fungal disease that causes wilting and yellowing of the leaves. Avoid overwatering and ensure good drainage. Remove and destroy infected plants.
- Root Rot: Caused by overwatering and poor drainage. Improve drainage and avoid overwatering.
Organic Pest and Disease Control:
Whenever possible, use organic methods to control pests and diseases. Neem oil is an effective broad-spectrum insecticide and fungicide. Insecticidal soap can control aphids and other soft-bodied insects. Bacillus thuringiensis (Bt) is a biological insecticide that can control caterpillars. Copper fungicide can help control fungal diseases. Companion planting can also help deter pests. For example, planting basil near tomatoes can help repel tomato hornworms.
Harvesting and Storing Your Basil
Knowing when and how to harvest and store your basil ensures you enjoy its flavor for as long as possible. The best way to harvest basil involves timing and technique.
When to Harvest:
Harvest basil leaves in the morning, after the dew has dried but before the heat of the day sets in. This is when the leaves have the highest concentration of essential oils, resulting in the best flavor.
How to Harvest:
Use sharp scissors or pruners to cut the stems just above a set of leaves. Avoid tearing the leaves, as this can bruise them and reduce their flavor. Harvest frequently to encourage continuous production.
Storing Basil:
Fresh basil is best used immediately, but you can store it for a few days. There are several methods for storing basil:
- Refrigeration: Place basil stems in a glass of water like flowers and cover the leaves loosely with a plastic bag. Store in the refrigerator for up to a week.
- Freezing: Blanch basil leaves for a few seconds in boiling water, then transfer them to an ice bath. Drain the leaves and pat them dry. Freeze them in a single layer on a baking sheet, then transfer them to a freezer bag or container. Frozen basil is best used in cooked dishes.
- Drying: Dry basil leaves in a dehydrator or in a low oven. Store dried basil in an airtight container in a cool, dark place. Dried basil has a less intense flavor than fresh basil.
- Basil Pesto: Make a batch of pesto and freeze it in ice cube trays. Once frozen, transfer the pesto cubes to a freezer bag or container. This is a great way to preserve the flavor of fresh basil for months.
