Seeds can be added to fruits or vegetable salads. Sunflower seeds are also a good substitute for nuts while baking.

Follow the steps mentioned here to grow sunflowers in a pot:

Step 1: Buy sunflower seeds and container

  • You can buy sunflower seeds from a local nursery or garden, or order them online. For buying exotic sunflower seeds, see online.
  • If you already have a fully grown sunflower plant, take the seeds and store them in an airtight container inside the fridge.
  • Plant the seeds as early as possible as older seeds shall be harder to grow.

Step 2: Choose the sunflower variety

  • Look for a dwarf variety of sunflowers to grow in your container.
  • Read over the packet of sunflower seeds or website for variety while making a purchase. It will have instructions about the growing process of that breed.
  • If you are buying from a local garden or nursery, you can also ask an associate for help.
  • If you want sunflowers all summer, you need to replant every 10 to 14 days. The single-stem sunflowers grow a single flower from a seed. Nevertheless, these varieties are pollen-less, therefore they won’t drop pollen on your furniture, or clothes.
  • Whereas branching sunflowers get many flowers during the season. They have different colours such as burgundy and chocolate.

Step 3: Choose the right size container.

  • It is important that the size of your container is according to the height and the number of flowers you want in each container. Like, you can plant most dwarf sunflowers in a 12 to 16 in (30 to 41cm) pot.
  • Mammoth sunflowers require a container that has a capacity of at least 19 litres.
  • If you are unsure of the size, go for a larger pot. Sunflowers need good space in order to grow.
  • If you are using an old container, clean and sterilise it thoroughly. Make sure it has drainage otherwise your seeds may rot.
  • Place a plate or saucer under the container to prevent water run-off.

Step 4: Put compost and potting soil

  • Select good quality, nutrient-rich topsoil for planting sunflowers. Adding compost to soil makes it rich in nutrients for your sunflowers.
  • Usage of high-quality topsoil will prevent you from adding any drainage material, such as sand or rocks to the bottom of the container.

Step 5: Plant your Sunflower

  • Dig each seed about an inch into the soil.
  • For planting more than one seed, you need to sow the seeds 4 to 5 inches (10 to 13 cm) apart. You can also add a thin layer of compost to the topsoil after sowing the seeds.
  • Make sure there is a space of 4 to 5 inches (10 to 13 cm) along all sides of each seed. Avoid sowing them too close to the edges of the container.

Step 5: Water your seeds every day

  • Sunflowers’ water requirement in their growing period is more than most of the plants. Soil should remain moist and well-drained all time. Give your sunflowers at least 7.6 litres of water a week at the time of germination of seeds.
  • If you do not give sufficient water during their growing stage, then sunflowers will have thin, weak stems, unable to hold the heavy flower head up.
  • The indication of well-drained soil is that water flows through it quickly. If the water is standing in your pot, there exists a drainage problem.

Step 6: Keep a watch as seeds germinate

  • Sunflower seeds should start to grow into small seedlings in 7 to 10 days. Water it regularly and make sure the soil is moist.
  • If your sunflowers are outside, then you may have to cover the seedlings with baskets or nets to protect them from birds.

How to Plant and Maintain Sunflowers in Containers

The Lemon Queen Sunflower, a dwarf variety of the Sunflower (Helianthus annuus), is a good option for container planting. The sunflower is hardy, resisting drought easily once it becomes established (needs plenty of water beforehand). Not only can it survive a variety of environmental conditions, but it also produces an abundance of seeds, which is good for birds, other pollinators, and even humans! In addition, sunflowers have beautiful, large flowers which make a great addition to your home.

Sunflowers grow best in locations with full sun, blooming during summer or early fall. They prefer long, hot summers to flower well, but can also grow well in locations with shorter summers. The mature height of the Lemon Queen Sunflower is approximately 5 feet ( 1.5 meters) which is smaller than the common variety of sunflower.


  • Sow seeds 4-5 inches apart and 1/2 inch deep directly into pots filled with well moistened, good quality potting mix. It takes approximately 8-10 days to germinate.
  • When seedlings are several inches tall, transplant them to larger pots that are at least 12-18 inches deep while making sure that they are spread out. In other words, no more than 1 plant per 8 inch pot (diameter), or 3 plants per 15 inch pot. In large planters, you can keep the seedlings 6 inches apart.
  • Keep soil moist and well weeded. Protect seedlings from hungry or nesting birds with netting or plastic berry baskets.
  • Place container in an area with plenty of direct sunlight.
