Whether you have a sunny windowsill, a small balcony, or a full backyard garden, learning how to grow basil and rosemary successfully comes down to understanding their unique needs.
If you’ve been wondering how to grow basil and rosemary without killing them, you’re in the right place.
These two Mediterranean favorites have different water and light preferences, so knowing the tricks for each will keep them thriving.
In this post, we’ll break down the best practices for how to grow basil and rosemary, from planting and watering to harvesting and overwintering.
Let’s dig into the details so you can enjoy fresh herbs all season long.
How To Grow Basil And Rosemary: The Core Differences
The very first step in learning how to grow basil and rosemary is understanding that they are not the same plant.
Basil is a tender annual that loves warmth, moisture, and rich soil.
Rosemary is a woody perennial that prefers drier conditions, leaner soil, and plenty of sunshine.
Trying to treat them identically is the most common mistake beginners make.
So when you plan how to grow basil and rosemary together, you’ll need to respect their individual personalities.
The good news is that both still thrive in similar containers and sunny spots.
You just need to adjust watering schedules and soil mixes.
Let’s look at each herb separately so you know exactly what to do.
1. How To Grow Basil: Sun, Soil, And Water
Basil is a sun worshipper that needs at least 6 to 8 hours of direct sunlight daily.
If you’re growing basil indoors, place it on a bright south-facing windowsill.
For outdoor gardens, choose a spot that gets morning sun and some afternoon shade in hotter climates to prevent leaf scorch.
When it comes to soil, basil loves rich, well-draining potting mix amended with compost.
Keep the soil consistently moist but never soggy, as basil leaves will wilt quickly if the roots dry out.
Water at the base of the plant rather than overhead to avoid fungal diseases like downy mildew.
You can grow basil from seeds indoors about 6 weeks before the last frost or simply buy young transplants.
Pinch off flower buds as soon as they appear, because basil that flowers will slow down leaf production and turn bitter.
This simple maintenance habit is the secret to a long harvest.
2. How To Grow Rosemary: Drought-Tolerant And Hardy
Now for the other half of how to grow basil and rosemary, let’s focus on rosemary.
Rosemary prefers full sun and actually thrives on neglect when it comes to watering.
This Mediterranean herb hates wet feet, so well-draining soil is non-negotiable.
Use a sandy or gritty mix, or add perlite to a regular potting soil to improve drainage.
When growing rosemary in the ground, avoid heavy clay that holds moisture.
Water rosemary deeply but infrequently, allowing the top inch of soil to dry out completely between waterings.
Overwatering is the fastest way to kill rosemary, so when in doubt, leave it alone.
Rosemary can be grown from seeds, but it’s notoriously slow to germinate.
Most gardeners find it easier to start with a cutting or a nursery-bought plant.
Once established, rosemary becomes a hardy perennial that can live for years in the right spot.
If you live in a colder zone, you’ll need to bring rosemary indoors for the winter or protect it with mulch.
Best Practices For Planting Basil And Rosemary Together
So, can you really figure out how to grow basil and rosemary in the same bed or planter?
Yes, but you need to be strategic.
Since basil loves moist, rich soil and rosemary prefers dry, lean conditions, consider using separate containers.
A large planter with a divider works well, or simply place two pots side by side.
If you insist on growing them together in the ground, plant rosemary on the drier edge and basil in the richer, watered center.
Space them at least 18 inches apart to allow for proper air circulation.
This reduces humidity around rosemary while keeping basil happy.
Another tip for how to grow basil and rosemary together is to mulch around basil but leave rosemary bare.
Mulch retains moisture for basil but can trap too much wetness around rosemary.
By following these spacing and watering tricks, you can have a successful herb garden with both plants.
Harvesting Basil And Rosemary The Right Way
Knowing how to grow basil and rosemary includes learning how to pick them without damaging the plant.
For basil, always snip leaves from the top of the plant, just above a pair of leaves.
This encourages bushier growth rather than a tall, spindly stem.
Never pull leaves from the bottom, as that exposes the plant to disease.
Regular harvesting keeps basil producing new leaves for months.
For rosemary, use clean scissors to cut sprigs from the outer edges of the plant.
Avoid cutting into old, woody stems because they won’t regrow easily.
Instead, focus on the soft, green tips.
Harvest rosemary in the morning after the dew dries, as that’s when the essential oils are most concentrated.
You can harvest both herbs anytime during the growing season.
The more you prune, the more vigorous the plants become.
Common Problems When Growing Basil And Rosemary
Even with perfect intentions, you might run into issues while figuring out how to grow basil and rosemary.
Basil’s most common problems are root rot, fungal spots, and aphids.
To prevent these, ensure good airflow, water early in the day, and avoid splash irrigation.
Yellowing lower leaves on basil usually mean you’re overwatering.
Rosemary’s biggest problems are root rot, powdery mildew, and spider mites.
If rosemary needles turn brown and drop, it’s often a sign of too much moisture.
Move rosemary to a hotter, drier location and let the soil dry out completely.
For both herbs, a simple organic insecticidal soap can handle most pests.
Always inspect new plants before bringing them home to avoid introducing pests to your garden.
