Fresh basil is one of the most popular herbs in kitchens worldwide. Its fragrant leaves can transform simple dishes like pasta, salads, and pizzas into something extraordinary. But if you’ve ever bought a lush little pot of basil from the supermarket, you probably know the frustration: within a week, it starts to wilt, turn yellow, and eventually die.
The good news? The problem isn’t you—it’s how these plants are sold. With the right approach, you can rescue supermarket basil and grow it into a thriving, long-lasting plant that provides fresh leaves for months. Here’s how to do it step by step.
Why Supermarket Basil Dies So Quickly
Supermarket basil isn’t actually one plant. If you remove it from its pot, you’ll notice a dense block of roots with 20–30 seedlings all crammed together. While this looks appealing in the store, it creates competition for space, light, and nutrients. The result is that no individual plant can truly thrive. These pots are meant for short-term use—snip some leaves for your dinner and toss the rest.
But if you want to grow basil long-term, you’ll need to separate and replant it.
Step 1: Divide the Basil
- Remove the plant from the pot. Gently squeeze the sides and ease it out. You’ll see a compact root ball.
- Separate the seedlings. Carefully tease apart the roots with your fingers. Don’t worry if some roots break—basil is tougher than it looks.
- Tip: Soaking the root ball in a bowl of water for a few minutes makes this process easier.
- Keep one seedling per pot. Crowding two or three together may look nice, but one plant per pot grows much stronger and healthier.
Step 2: Repot Properly
- Choose the right container. Use small to medium-sized pots with drainage holes. The original supermarket pot size usually works fine.
- Use quality soil. A light, well-draining mix works best. Indoors, a blend of coconut coir and perlite helps reduce gnats, while outdoors, general compost is enough.
- Plant your seedlings. Place one basil seedling in each pot, fill around it with soil, and press gently to secure.
- Water thoroughly. Give each pot a deep drink until water drains from the bottom.
Step 3: Provide the Right Environment
Basil comes from the Mediterranean, so think warmth and sunshine.
- Light: Basil needs at least 6 hours of direct sunlight daily. A sunny south-facing window is ideal. If that’s not possible, supplement with a small grow light for 10–12 hours a day.
- Temperature: Basil prefers temperatures above 12°C (54°F). Cold nights or drafts from windows can stunt growth, so keep it in a warm spot.
- Watering: Basil likes consistently moist soil, but not soggy. Check with your finger—if the top inch feels dry, water thoroughly. Avoid letting the pot sit in standing water.
Step 4: Prune, Don’t Just Pick
Here’s the secret to a bushy basil plant: pruning instead of plucking.
- Wait until your basil has at least two sets of leaves on the main stem.
- Cut the stem just above a pair of leaves. This encourages two new stems to grow from that point.
- Repeat this process as the plant grows. Each time you cut, the plant branches out more, creating a dense, leafy basil bush instead of one tall, leggy stalk.
This method not only keeps your plant healthy but also gives you more leaves to harvest in the long run.
Step 5: Propagate for Endless Basil
You don’t have to stop at one plant. Basil is one of the easiest herbs to propagate.
- Take cuttings. When you prune, keep stems that have at least a couple of leaf pairs.
- Place in water. Strip off any leaves that would sit below the water line, then place the cutting in a glass of water.
- Wait for roots. Within a week, tiny white roots will appear. Once they’re a few centimeters long, transplant into soil.
This gives you an endless supply of basil plants for free.
Step 6: Feed for Strong Growth
Fast-growing basil quickly uses up the nutrients in its potting soil. To keep it productive:
- Use a balanced liquid fertilizer every 2–3 weeks.
- Tomato feed or any general-purpose plant food works fine.
- Don’t overdo it—too much fertilizer can make the leaves bitter and attract pests.
Caring for Basil: Quick Checklist
- Light: Minimum 6 hours of direct sunlight or grow light.
- Temperature: Keep above 12°C (54°F).
- Watering: Moist soil, not soggy.
- Pruning: Always cut above leaf nodes for bushier growth.
- Feeding: Light, regular fertilizer to maintain flavor and strength.
Final Thoughts
Supermarket basil isn’t designed to last, but with a little care, you can transform it into a thriving, productive plant that provides fresh leaves for months. By separating the seedlings, repotting them properly, and following the right pruning technique, you’ll have healthy basil that grows stronger with each harvest.
With just a few minutes of care each week, you’ll always have fresh, fragrant basil on hand—perfect for sauces, salads, and garnishes. Instead of watching your supermarket herb wither away, you’ll be growing a steady supply of one of the most beloved herbs in the world.
