Are you looking for some tips on growing giant sunflowers? If yes then you have reached the right place. I have been gathering tips and tricks on growing giant sunflowers which I want to share with you people to enable you to grow these huge sunflowers to beautify your garden as well.

Choose a Location

If you want your sunflowers to grow at their utmost height then you should choose a well drained location so that they can receive maximum amount of sunlight. Sunflowers’ heads are always faced towards east so such a location should be selected where sunflowers are in full view of sunrise.

Choosing Sunflower Seeds

Since you want to grow huge sunflowers, you will require picking “tall” types seeds. The most successful varieties in this regard are “Kong” and “Mammoth” because these varieties can grow up to a height of 10-20 feet producing huge and attractive sunflowers.

Digging Holes

To grow giant sunflowers, you will require digging a hole having a circumference of 2 feet and a depth of 18 inches. The holes should be dug in such a way that center of one hole is two feet away from the center of previous hole. Remember that more space between sunflower plants result in larger flowers and thinner stalks while less space may result in smaller flowers and thicker stalks so if you want huge sunflowers to grow ideally, you will require maintaining a space of 24 inches between two plants.

Preparing the Soil

Ordinary sunflowers can grow in poor soil conditions but giant sunflowers cannot so prepare the soil carefully. After loosening the soil you have removed from holes, remove rocks, roots and stones from soil. Prepare a mixture of half a shovel of potting mix and half shovel of humus and then back fill your holes with this mixture.

Planting Seeds

The best time for planting giant sunflower seeds is from mid May to early June. While planting seeds, make sure that you are planting three seeds in each hole. These seeds should be positioned about an inch apart form each other. Push each seed in soil to a depth of one inch. You can use your finger for this purpose. After planting the seeds, sprinkle a little soil over buried seeds and then pat the soil using your hands.

Watering Giant Sunflowers

Giant sunflowers consume a lot of water but remember that over watering these plants may soften the roots making them incapable of supporting the huge plant.  Don’t water sunflowers in case of puddling but after that if you feel that soil has dried out, water your giant sunflowers.


A liquid fertilizer should be used after every 1-2 weeks. Remember not to fertilize the flower or the stalk directly because it may rotten and weaken your plant. Instead of it, pour liquid fertilizer around the base of plant.

These were some simple and easy steps to grow huge sunflowers. Follow these and have giant and beautiful sunflowers in your house.

Sunflowers are most loved flowers because in summer, they add color to your garden and in winter, potted sunflowers indoors brighten a sad and dull winter day. Sunflowers are among those flowers which require a lot of light so the people who want to grow sunflowers indoors must have a proper arrangement of light. The best thing you can do in this regard is to use a fluorescent light to grow your sunflowers indoors. Fluorescent lights are quite beneficial for growing sunflowers indoors whether you are growing them in winter or growing them to plant outdoors later. Here I am going to provide you some tips that will make it easy for you to grow sunflowers indoors with fluorescent light:

  • Firstly, you will prepare your pots in which you are going to plant your sunflowers so fill the pots with a fertile potting mix containing moss, peat and compost. If you have a plan to transplant the seedlings later then you can use small pots. But make sure that these pots should have a diameter of at least one foot so that they can handle large roots of sunflowers.
  • As you are going to grow flowers indoors so you are needed to choose smallest types of sunflowers like Teddy Bear and Big Smile. These two varieties are best choices for potted sunflowers as they can’t grow more than two feet tall.
  • Now it comes to plant the seeds. While doing this, make sure that you are planting two or three seeds in a pot. After sowing the seeds almost two inches deep, water them well.
  • As natural light is best for the growth of sunflowers, place the pots in a sunny window. Fluorescent light is used to fulfill deficiency of exposure to natural light in winter.
  • Try to use the brightest fluorescent light for your indoors sunflowers and put the lights in a fixture which is capable of holding two tubes. Arrange these lights in such a way that they are few inches away from the soil surface. The purpose of using lights is to make sure that sunflower seeds receive 12 hours of light in a day either all light from fluorescent tubes or by the combination of natural and artificial light.
  • When you see that your seedlings have begun to grow, raise the lights to provide them enough room for their growth. Ensure that lights are always a few inches from the tallest plant.
  • Fluorescent lights should be kept on indoors sunflowers for their whole life to make sure that your sunflowers are getting lights for 12 hours a day until the plants begin to produce flowers.

That was all about growing sunflowers indoors using artificial lights. These steps are quite simple so you can easily follow them to make your home looming bright even in gloomy winter season.

Perennial sunflowers, which are mostly grown in vegetable gardens, are more refined and popular than annual sunflowers because they have finer leaves and smaller flowers. There are some kinds of perennial sunflowers which can grow up very tall. I have also grown some of perennial sunflowers in my garden and I suggest you to do the same because these flowers are not only beautiful but also attract butterflies and birds. Here I have made a list of perennial sunflowers from which you can choose one to grow in your garden.

Thin-Leaved Sunflowers

Thin-leaved sunflowers can grow up to five feet tall provided that they are planted in full sun or partial shade. They are quite popular among growers because they are adaptable to different soil and light conditions. Having bright yellow color with a greenish central cone, these sunflowers are long lasting when used as cut flowers. This plant produces more flowers when it is properly deadheaded. Best growing season for these sunflowers is late summer or early fall as they are at their peak at these times of year.

Maximilian’s Sunflowers

This type of perennial sunflowers is the tallest among perennial sunflowers as it can grow up to six to seven feet tall. Its height can vary depending upon soil conditions and humidity. These plants produce bright yellow flowers from mid summer to late summer.

Swamp Sunflowers

Having yellow flowers with dark centers, these flowers are native to East Coast. Their best attribute is that they can tolerate damp soil conditions which other plants can’t. Its blooming season starts from late August and continues until October. These plants can also grow up to seven feet tall.


This plant produces golden-yellow flowers all summer and can grow up to a height of four to five feet. These sunflower plants attract butterflies and hummingbirds and due to this quality, I have also grown these in my home garden. Flore-pleno is resistant to pests and diseases and requires partial shade to grow well.

Woodland Sunflowers

Like swamp sunflowers, these are also native to East Coast. These sunflowers naturally grow in wooded areas having clear-yellow flowers and stiff leaves which are like sandpaper. These sunflowers are a good choice for those gardens which have partially shaded locations.

Sunflowers are beautiful creature of God which adds colors and beauty to a garden so consider growing any of the above perennial sunflowers to beautify your garden.
