Ever walk through the supermarket and eye that vibrant, leafy bunch of basil, dreaming of fresh pesto and summer salads? What if I told you, you don't need a sprawling garden to enjoy that very basil, regrown in your own home? It's easier than you think, and this guide will show you how!
How To Grow Supermarket Basil: A Step-by-Step Guide
Understanding Supermarket Basil
Before we dive into the how-to, let's understand what we're working with. Supermarket basil is often grown in a greenhouse environment and is typically sold as a bunch of cuttings, rather than a fully rooted plant. This means it's primed for propagation – turning those cuttings into new, thriving basil plants. Understanding this is crucial because it informs our entire approach to growing it. We're not just planting a seed; we're essentially cloning the basil!
Selecting the Right Basil
Not all basil bunches are created equal. When choosing your basil at the supermarket, look for several key things:
- Healthy Leaves: Avoid bunches with yellowing, wilting, or spotted leaves. Vibrant green is what you're after.
- Strong Stems: The stems should be firm and upright, not flimsy or broken.
- Multiple Stems: The more stems, the more chances you have for successful propagation.
- No Flowers: If the basil has already started to flower, it's focusing its energy on reproduction, not leaf growth. While you can still try to propagate it, your chances of success are lower.
Picking a healthy bunch of basil is the foundation of successful regrowing. Think of it like choosing the right ingredients for a recipe – the better the ingredients, the better the final product.
How To Propagate Supermarket Basil
This is where the magic happens! Turning those cut stems into independent basil plants. Don't worry, it's not complicated.
Step 1: Preparing the Cuttings
Carefully remove the leaves from the lower 2-3 inches of each stem. This is important because these areas will be submerged in water and we don't want the leaves to rot and contaminate the water. Rotting leaves can also hinder root growth. Use sharp scissors or pruning shears to make a clean cut. Avoid tearing the stem.
Step 2: Rooting in Water
Place the prepared stems in a glass or jar filled with fresh, clean water. Make sure the bare stems are submerged, but the leaves are above the water line. A clear glass is best so you can monitor root growth. Place the glass in a bright location, but away from direct sunlight. Direct sunlight can overheat the water and damage the stems. Change the water every 1-2 days to prevent bacterial growth. This keeps the water fresh and provides oxygen to the developing roots.
You should start to see roots forming within a week or two. Be patient! The speed of root growth depends on factors like temperature and light. Some varieties of basil might root faster than others.
Speaking of outdoor maintenance, having the right tools can make all the difference. I've found a quality watering tool really helps, and this Garden Hose 75 FT with 10-Function Nozzle, Leak-proof Metal Connector Water Hose – basically a very durable and versatilegarden water hose– has been a game-changer in my yard.

Step 3: Planting the Rooted Cuttings
Once the roots are about an inch or two long, it's time to plant your new basil plants in soil. Choose a pot that's at least 4-6 inches in diameter. This gives the roots enough room to grow. Use a well-draining potting mix. Basil doesn't like to sit in soggy soil. Gently remove the rooted cuttings from the water and plant them in the prepared pots. Water thoroughly after planting. Make sure the soil is moist, but not waterlogged.
Caring for Your Regrown Basil
Light
Basil thrives in bright, sunny locations. Aim for at least 6 hours of direct sunlight per day. If you don't have enough natural light, you can supplement with a grow light. Insufficient light can lead to leggy growth and weak plants.
Watering
Keep the soil consistently moist, but not waterlogged. Water when the top inch of soil feels dry to the touch. Overwatering can lead to root rot, so it's important to strike a balance. Basil prefers to be watered deeply, rather than frequent shallow watering.
Fertilizing
Feed your basil plants with a balanced liquid fertilizer every 2-4 weeks. This provides the essential nutrients for healthy growth. Follow the instructions on the fertilizer label. Over-fertilizing can burn the roots, so it's best to err on the side of caution.
A great fertilizer for Basil:
- NPK Ratio: 10-10-10
- Micronutrients: iron, manganese, zinc
Basil loves nutrients, you'll have to ensure that you're replenishing the loss nutrients.
Pinching and Pruning
Pinching and pruning are essential for encouraging bushy growth and preventing your basil from flowering too early. When the plant is about 6 inches tall, pinch off the top set of leaves. This encourages the plant to branch out and produce more leaves. Regularly prune your basil to remove any yellowing or damaged leaves. This keeps the plant healthy and encourages new growth.
Potential Problems and Solutions
Even with the best care, you might encounter some problems. Here are a few common issues and how to address them:
- Yellowing Leaves: Could be a sign of overwatering, underwatering, or nutrient deficiency. Adjust your watering schedule and fertilize as needed.
- Wilting: Could be a sign of underwatering or extreme heat. Water thoroughly and provide shade during the hottest part of the day.
- Pests: Aphids, spider mites, and whiteflies can attack basil plants. Insecticidal soap or neem oil can be used to control these pests.
- Root Rot: A fungal disease caused by overwatering. Ensure good drainage and avoid overwatering.
Harvesting and Using Your Homegrown Basil
Once your basil plants are established, you can start harvesting the leaves. Simply snip off the leaves you need with scissors or pruning shears. Harvest regularly to encourage continued growth. Basil is best used fresh, but you can also dry or freeze it for later use. Fresh basil is a culinary treasure. You can use it in countless dishes, from pesto and pasta sauces to salads and soups. Enjoy the fruits (or rather, leaves) of your labor!
So there you have it! Growing supermarket basil is a simple and rewarding way to enjoy fresh herbs at home. With a little care and attention, you can transform a grocery store bunch into a thriving supply of flavorful basil. Happy growing!
