Starting from Seeds
Starting from seeds is a straightforward process. You can use any container that holds soil and has drainage, or even a plastic cup, as long as you punch some holes in it.
To prepare the soil, use a growing medium like coco coir or a potting mix without chunky materials. Add water until the soil is moist, but not dripping wet. You can also add a little worm castings to give your seeds a nutrient boost.
Sow the seeds on the surface of the soil or press them down gently into the soil. Add water to ensure the seeds have enough moisture to germinate. Keep the soil consistently moist, but avoid waterlogging. The ideal temperature for germination is between 70°F to 85°F (21°C to 29°C).
Growing from Seeds
Growing from seeds is a great way to start your culantro journey. You can use any container that holds soil and has drainage, even a plastic cup will do.
To prepare the soil, fill the container with growing media like coco coir or a potting mix without chunky materials. Add water until it's moist, not dripping wet.
You can add a little bit of worm castings to keep the seeds well-fed, but it's not necessary. Simply add the seeds, about 20-30 of them, and cover with a bit of soil or press them down into the soil.
Water the seeds to ensure they have enough to kick off germination. Keep the soil consistently moist but avoid waterlogging.
The ideal temperature for germination is between 70°F to 85°F (21°C to 29°C). Provide indirect sunlight or partial shade to help the seeds thrive.
Here's a quick summary of the germination process:
The germination process typically takes 7-14 days when conditions are just right. With the right care, your seeds will start to sprout and grow into healthy culantro plants.
Seed Characteristics

Starting from seeds can be a wonderful way to grow your own herbs and vegetables.
Culantro seeds are small, dark, and oval-shaped, making them easy to identify.
These characteristics are essential when selecting seeds for planting.
Proper storage conditions can help keep these seeds viable for 1-2 years.
This means you can store them safely and have a reliable supply for planting.
Seedling Stage
The seedling stage is a crucial period in a culantro's life cycle, and it's amazing to see these tiny plants start to grow. During this stage, culantro typically reaches heights of 1-2 inches, and its leaves are small, tender, and smooth.
These initial leaves are less serrated compared to the mature foliage that will develop later, which is a notable change that will occur as the plant grows. It's essential to provide the right conditions for your seedlings to thrive.
Germination typically takes 7-14 days when conditions are just right, so be patient and keep the soil consistently moist but avoid waterlogging.

Germination Duration
Germination typically takes 7-14 days when conditions are just right. This is a crucial period for your culantro seeds, and understanding it will help you provide the best environment for growth.
Soaking seeds for 24 hours can enhance germination rates. This simple step can make a big difference in the success of your seedlings.
Planting seeds about 1/4 inch deep in well-draining soil is essential for optimal results. This allows the seeds to germinate evenly and reduces the risk of rot or other issues.
Here's a quick rundown of the germination process:
Seedling Stage Characteristics
The seedling stage is a critical time for culantro growth. During this stage, you'll notice small, tender leaves that typically reach heights of 1-2 inches.
These initial leaves are smooth and less serrated compared to the mature foliage that will develop later. The seedling stage is a delicate time, and providing the right conditions is essential for healthy growth.

Aim for warm temperatures between 70°F to 85°F, high humidity, and well-draining soil to support healthy growth. This will help your culantro establish a strong foundation for future development.
The seedling stage lasts approximately 2-4 weeks, setting the groundwork for future growth. It's a crucial time where the plant begins to establish itself and develop its root system.
Growth and Development
Culantro seedlings typically experience rapid leaf development and height increase during the vegetative growth stage, reaching up to 18 inches tall.
This stage can last anywhere from 4-6 weeks, requiring specific conditions for success, including warm temperatures between 70°F to 85°F, high humidity, and well-draining soil.
During this time, you'll notice a significant change in leaf structure, with leaves becoming serrated and robust, while the root system establishes a solid foundation for future growth.
Here's a rough estimate of the growth stages of culantro seedlings:
After the vegetative growth stage, culantro seedlings will transition into the maturation stage, which typically lasts around 4-6 weeks from the time of flowering, allowing for quick turnaround in your gardening efforts.
Vegetative Growth

During the vegetative growth stage, culantro experiences rapid leaf development and height increase, reaching up to 30 inches tall and showcasing its vibrant green foliage.
This stage typically lasts 4-6 weeks, requiring specific conditions for success. To support healthy growth, aim for warm temperatures between 70°F to 85°F, high humidity, and well-draining soil.
As culantro transitions from seedlings to lush plants, you'll notice a significant change in leaf structure. The leaves become serrated and robust, while the root system establishes a solid foundation for future growth.
Culantro thrives in full sun, but there seems to be some consensus among growers that it will be more productive over a longer period if grown in partial shade. The leaves grow larger and more tender this way.
Here's a rough guide to the vegetative growth stage:
During this stage, the plant is establishing its root system and developing its leaf structure, setting the groundwork for flowering and seed production.
Maturation Time
The maturation period for culantro seeds is about 4-6 weeks from the time of flowering. This relatively short timeframe allows for quick turnaround in your gardening efforts.
Culantro seeds take approximately 4-6 weeks to mature, which is a significant reduction compared to other plants. This makes it an ideal choice for gardeners who want to see quick results.
The duration of the seedling stage, which lasts around 2-4 weeks, sets the foundation for the maturation period that follows. This early growth is crucial for establishing a strong plant that can thrive during the maturation phase.
As a gardener, I can attest that the maturation time for culantro seeds is indeed relatively short. This allows for multiple harvests throughout the growing season, making it a great crop for those who want to maximize their yields.
Maturation and Lifespan
Culantro seedlings are a delight to grow, and understanding their maturation and lifespan can help you make the most of your gardening efforts.
The maturation period for culantro seeds is about 4-6 weeks from the time of flowering, which is relatively short and allows for quick turnaround in your gardening efforts.
Growing culantro can be a continuous process, as it can produce seeds multiple times during its lifespan.
Culantro typically lives for 1-2 years, depending on the environmental conditions it faces.
This relatively short lifespan means you can expect to replace your culantro seedlings every year or so, but the quick turnaround time makes it easy to do so.
Frequently Asked Questions
Does culantro grow back every year?
Culantro is technically a biennial plant, but it can be grown as an annual in areas with warm winters, allowing it to grow for two years. In regions with mild winters, it will regrow year after year.
Can I grow culantro from store bought?
Yes, you can grow culantro from store-bought plants, but look for the healthiest ones with intact crowns for the best results. With a little care, you can root them yourself and enjoy a steady supply of this unique herb.
