How To Grow Cinnamon Basil: The Basics
Growing cinnamon basil isn’t complicated, and it follows many of the same principles as growing standard sweet basil, but with a few specific preferences.
Learning how to grow cinnamon basil successfully starts with understanding its love for warmth and sunlight.
This variety, also known as Ocimum basilicum ‘Cinnamon’, is a true basil with a spicy twist.
When you’re figuring out how to grow cinnamon basil, remember that it’s an annual in most climates, meaning it completes its life cycle in one season.
However, if you live in a frost-free zone, you can actually grow cinnamon basil as a perennial.
The key to growing cinnamon basil is to mimic its native tropical environment as closely as you can.
1. Start With Seeds Or Seedlings
You can grow cinnamon basil from seeds, which is very rewarding, or you can purchase young cinnamon basil plants from a nursery for a head start.
If you’re starting from seed, sow them indoors about six to eight weeks before your last expected frost date.
Plant the cinnamon basil seeds about a quarter-inch deep in a seed-starting mix.
Keep the soil consistently moist and warm, around 70°F (21°C), and your cinnamon basil seeds should germinate within five to ten days.
Once the seedlings have a couple of sets of true leaves, you can transplant them into larger pots or harden them off for the garden.
2. Provide Full Sun And Warm Temperatures
When you grow cinnamon basil, one of the most crucial factors is sunlight.
These plants crave at least six to eight hours of direct, bright sunlight each day.
The more sun your cinnamon basil gets, the more flavorful and robust the leaves will be.
In very hot climates, a little afternoon shade can be beneficial, but generally, full sun is best for growing cinnamon basil.
Temperature is just as important; cinnamon basil absolutely thrives in warm weather.
Don’t rush to plant it outside until the nighttime temperatures are consistently above 50°F (10°C).
Cold snaps can stunt growth or even kill a young cinnamon basil plant, so patience is key when you grow cinnamon basil.
Perfecting The Soil And Watering For Cinnamon Basil
Getting the soil right is a big part of how to grow cinnamon basil successfully.
This herb prefers rich, loamy soil that drains extremely well.
Heavy, waterlogged soil is a common reason for failure when people try to grow cinnamon basil.
To create the ideal environment for growing cinnamon basil, mix in plenty of compost or well-rotted manure before planting.
A slightly acidic to neutral pH, between 6.0 and 7.5, is perfect for cinnamon basil plants.
1. Watering Consistency Matters
Watering is a delicate balance when you grow cinnamon basil.
These plants like consistent moisture, but they absolutely hate having “wet feet.”
A good rule of thumb is to water deeply when the top inch of soil feels dry to the touch.
During hot summer days, your cinnamon basil might need watering every day, especially if it’s in a container.
Using a layer of mulch around your cinnamon basil plants in the garden can help retain soil moisture and keep the roots cool.
Always water at the base of the plant to keep the foliage dry and prevent fungal diseases, which is a key tip for growing cinnamon basil.
2. Feed For Flavor And Growth
To encourage vigorous, healthy growth when you grow cinnamon basil, regular feeding is a great idea.
A balanced, water-soluble fertilizer applied every four to six weeks can work wonders.
However, be careful not to over-fertilize your cinnamon basil, as this can reduce the concentration of essential oils that give it that unique flavor.
If you started with rich, compost-amended soil, your cinnamon basil might need very little extra feeding throughout the season.
A light feeding with a liquid seaweed or fish emulsion is often all that’s needed for successful cinnamon basil growing.
Pruning, Pests, And Problems When Growing Cinnamon Basil
Part of learning how to grow cinnamon basil is knowing how to maintain the plant for continuous harvest.
Regular pruning is perhaps the most important maintenance task when you grow cinnamon basil.
Pinching back the tips of the stems encourages the plant to become bushier and produce more leaves.
As soon as you see flower buds forming, pinch them off.
Allowing your cinnamon basil to flower signals the plant to stop producing new leaves and focus on seed production, which ends your harvest.
1. Keep An Eye Out For Common Pests
Like many herbs, cinnamon basil can attract a few common garden pests.
Aphids, spider mites, and Japanese beetles are the usual suspects you might find on your cinnamon basil plants.
Regularly inspect the undersides of leaves for aphids and mites, and wash them off with a strong spray of water if you spot them.
For larger pests like beetles, handpicking them off your cinnamon basil in the early morning is often the most effective method.
Neem oil is a good organic option for controlling a more severe infestation on your cinnamon basil.
2. Ensure Proper Air Circulation
Good air circulation is essential when you grow cinnamon basil to prevent fungal issues like powdery mildew and downy mildew.
Space your cinnamon basil plants adequately, about 12 to 18 inches apart, to allow for air to flow freely between them.
Avoid overhead watering, and water your cinnamon basil in the morning so any moisture on the leaves evaporates quickly.
If you do see signs of mildew on your cinnamon basil, remove the affected leaves immediately to stop the spread and improve airflow.
Harvesting And Using Your Cinnamon Basil Bounty
The best part of learning how to grow cinnamon basil is, of course, the harvest.
You can start harvesting your cinnamon basil leaves once the plant is about six inches tall and has plenty of foliage.
Regular harvesting is actually a form of pruning that encourages even more growth from your cinnamon basil.
For the freshest flavor, pick cinnamon basil leaves in the morning after the dew has dried, when the essential oil content is at its peak.
You can use your harvested cinnamon basil fresh, or you can dry the leaves for later use.
Store dried cinnamon basil in an airtight container away from direct light to preserve its unique aroma.
So, How Do You Grow Cinnamon Basil Successfully?
You can absolutely grow cinnamon basil successfully by focusing on the fundamentals of sun, warmth, soil, and water.
Growing cinnamon basil is a straightforward process once you understand its preferences for full sun and well-drained, fertile soil.
By keeping a consistent watering schedule and not letting your cinnamon basil dry out completely or sit in soggy ground, you’ll avoid most problems.
Don’t forget to pinch and prune your cinnamon basil regularly to keep it productive and prevent it from getting leggy.
With a little attention and care, you’ll find that growing cinnamon basil is one of the most fragrant and rewarding gardening tasks you can undertake.
So, whether you’re planting it in a sunny garden bed or a pot on your patio, you now have all the knowledge to grow cinnamon basil with confidence.
Happy growing and even happier tasting!
