They’re not only beautiful garden plants but also widely used for medicinal purposes.
These plant species are easy to grow in your garden and don’t need much care. They thrive easily in an area that gets plenty of sunshine throughout the day.

How to grow Echinacea plant from seed
Where to grow Echinacea plants?
Cornflower is not indoor plant as they grow nearly 2 feet tall and spread a lot. So it’s better to transplant them directly in your garden or yard.
Or you can first grow them in a pot and later transplant them in your yard.

Do Echinacea seeds need to be soaked before sowing in soil?
It’s not necessary to soak seeds before planting. But, if you soaked the seeds in water or combined them with sand and placed them in the refrigerator for a week.
Then, the seeds might germinate faster when you sow them.
Soil for Echinacea
Cornflowers are versatile plants and can thrive in rocky, sandy, and clay soil. But, for better growth, you should use rich compost soil and keep them well-drained.
Generally, they grow easily in any soil but ideally soil pH level should be 6.5 to 7.0. You can check the pH level of soil with the help of a pH checker.
Plants need sunlight as soon as sprouts start growing as it helps them in photosynthesis. Cornflowers are heat tolerant and refer to full sun or partial shade in warm climates.

They need at least 4-6 hours of sunlight every day to bloom.
Choose a spot that gets early morning light and afternoon shade. As the sunlight is more intense in the afternoon, if you have a hot climate region, especially in summer.
Excessive heat and light can fade their vibrant purple color blooms. Echinacea plants bloom within 90-120 days after planting, so you have to keep some patience.
If you plant in early spring just after winter, it will take a few months to get established.
How to Water
As I earlier mentioned, they are drought-tolerant and can live without water for many days.
But, when they are young much water is required for the development of new roots, so you have to water regularly.

After a few weeks when the plant gets well established, then water them a couple of days in a week.
To keep the soil moist you can cover them with a layer of mulch around the plant. Mulch stops water from evaporating rapidly.
Once Cornflower starts blooming, you can deadhead to encourage more flowers and keep them tidy.
Most of its species don’t like to be divided or transplanted as they established tap roots in the ground.

Taproots are very strong which makes division and transplant difficult. So, it’s better to plant them in a permanent spot, where you don’t need to transplant them.
Fertilizer for Echinacea
Cornflowers are not heavy feeders so you don’t need to fertilize regularly.
They are low-maintenance plant species that don’t need much fertilizer. But for fast growth, you can apply a balanced fertilizer in the growing season.
You can use organic fertilizers like tea bags or over-ripe bananas with water.
Companion plant for Echinacea
Companion plants provide nutrition, shade, and support to the plant. They assist in the growth of others by attracting beneficial insects and repelling pests.

Some of the popular companions for the Cornflower plant are Salvia, Catmint, Gentian, and Baby’s Breath.
Cornflower’s purple flowers contrast well with orange, yellow, and pink flowers.
Step to reduce disease
To keep your plant from fungal diseases free you should avoid watering from the top of the plant. Always water directly in the base of plants and avoid overwatering.
When you plant Cornflower maintain distance between them, otherwise they’ll stop growing. Planting too close will make spots crowded and plants can struggle for nutrition.
You should leave at least 12-24 inches (30-60cm) around the plants while planting.

When you plant it might look weird, but trust me once Echinacea gets mature it’ll cover the space.
This simple trick provides proper air circulation around the plant and prevents fungal diseases.
Besides this, you should always look at your plant if they have any spots or mildew on the leaves. If you find some immediately, cut off that part so that mildew does not get spread. It transmits from air and water, and throws or burns the affected parts.
How to Harvest Echinacea
As you know Cornflower plants are used for various purposes. They are used to make medicines, herbal tea, infusions, and decoctions.
The plant’s roots, leaves, and flowers are dried to make these products.

The harvesting of roots can be done once plants become 2-3 years old. To dry them, roots are cut into small pieces and exposed to direct sunlight for at least 2 weeks.
The leaves and flowers are harvested after 2 years in the growing season. They are cut from the stem and put flat to get dry in the sunlight.
After they dried, put them in an airtight container, out of sunlight, and further used to make tea.
