You will learn all about how to plant sunflower seeds in this article. This bright and breezy bloomer is easy to plant. The process of growing them is even simpler.

There is no plant that says summer like a sunflower. Like a smile on a stalk, the yellow blooms are bright and cheerful. Sunflower plants are easy to grow because they are heat resistant, pest resistant, and fast-growing. Their native habitat is North America, so they can adapt to almost any environment.

It is a beautiful flower, and you can use it for cutting flowers, or you can leave it on a stalk for a beautiful outdoor display, or you can eat its seeds. Sunflowers are easy to grow. Here’s how.


The sunflower is an annual plant. It looks like a giant daisy, with yellow (and occasionally red or brown) petals radiating from brown centers that ripen into seeds.

Several sunflower varieties reach 14 feet in height, making them tall, tough plants. It is possible to grow some of the smaller varieties in pots or small gardens because they are as short as a foot tall. The nectar and seeds of sunflowers attract bees and birds, making them a great choice for a wildlife or pollinator garden.

Botanical Name: Helianthus annuus

Common Name: Sunflower

Hardiness Zones: 2 to 11

Bloom Time: Sunflowers are most prolific during midsummer.

Planting Sunflowers

You can choose the right spot and place for your plants by following these steps.

  • The sunflower prefers to grow in places with six to eight hours of direct sunlight per day.
  • Sunflowers need a soil that is moist, well-drained, somewhat alkaline, and pH 6.0 to 7.5 due to their long tap roots.
  • Compost or other organic matter mixes well with nutrient-rich soil to improve sunflower health and produce the most blooms.
  • Choosing a smaller variety like “Short Stuff” or “Teddy Bear,” which has a shallow tap root, will enable you to grow sunflowers in pots.
  • Plant giant varieties that top 10 feet in height in a sheltered spot or along a fence so they can’t be affected by the wind. They could be blown over by a gust of wind otherwise.

Sunflower Planting Time

  • The soil temperature must reach 60 degrees before you plant seeds after the risk of spring frost has passed. You can expect this to occur between March and May, depending on where you live.
  • Starter plants are available at nurseries and home improvement stores, but growing sunflower plants from seed is easiest. If you grow sunflowers from seed, you can choose from more varieties. Sunflowers can also be grown from seed very easily.

Seed Planting for Sunflowers

  • Do not plant the seeds more than an inch deep and space them about 6 inches apart. Do not plant the seeds more than an inch deep and space them about 6 inches apart.
  • Starting in spring, sow a new row of seeds every two to three weeks for continuous blooms. It is called succession planting because it provides you with continuous blooms until frost.
  • What is the growth rate of sunflowers? The amount of time it takes for a seed to become a flower varies from 80 to 120 days, depending on the variety.

Sunflower care

  • When the plant is small, water the area around the roots about four inches away.
  • Water the plant deeply but infrequently once it is established to encourage deep root growth. If the weather is very dry or hot, water plants once a week with several gallons of water per plant.
  • The blooms on tall varieties may cause them to topple over. It is best to use bamboo stakes or other types of wood stakes.

Diseases and pests

A variety of fungal diseases can infect the plants, including downy mildew, rust, powdery mildew, and so on. Use a general garden fungicide to treat infected leaves. Keep reading about how to plant sunflower seeds.

The cutting of sunflowers for bouquets

  • Early in the morning is the best time to cut flowers, before the heat has stressed the plants. Taking blooms in the middle of a hot day can cause the flowers to wilt prematurely.
  • Cutting the main stem of sunflowers before their buds open will encourage the plant to make more blooms along the sides of the stem. The more flowers, the better.
  • It is important to handle cut flowers gently so that their petals do not fall off. Sunflowers can be kept in water at room temperature for about a week after they have been cut.

Sunflower Seed Harvesting

After the petals fall off, the brown middle of the sunflower will mature into a seed head. It is possible to harvest them and eat them (seeds make a nutritious snack) or to save the seeds for replanting next year. When growing sunflowers for seed collection and eating, follow these instructions of how to plant sunflower seeds:

  • On or off the stem, let the flower dry until the back of the head turns brown and the seeds are plump.
  • Cover the flower heads with garden fleece, cheesecloth or a paper bag after the seeds mature and the petals fall off the blooms to prevent birds and squirrels from getting the seeds.
  • Leave about 6 inches of stem after cutting off the plant’s head. Catch loose seeds in a container after placing the head in it.
  • The seeds can be removed by brushing your hand over the seed head and knocking them out.
  • Until you are ready to plant the seeds, store them in an airtight container in a cool, dry place.
