Sunflowers grow to an average height of 300 cm but the height is heavily dependent on the variety. Some are small enough and can be grown in pots. The different varieties also have different aspects such as the size of the heads. Furthermore, several ornamental species have red-colored ray florets.

One of the fascinating aspects of the sunflowers is that they have heliotropism. The young sunflower heads track the sun as it moves throughout the day. However, the tracking is only present in young sunflowers and it stops when they begin to bloom. Mature sunflowers generally face east.

Sunflower Types

Sunflowers can be considered as one of the easiest flowers to grow. Most of the varieties are heat and drought tolerant and can be grown all year round. All species do well in soil that is not waterlogged, in fact, waterlogging causes them to rot.

Sunflower types can be classified as either tall or dwarfs. It is also important to note that there are a number of sunflowers that produce colored petals which have different colors and not the common yellow or orange hue.

The tall varieties can reach up to as high as 16 feet tall. Some of the common tall varieties include;

Sunflower Growing

Sunflowers do well in areas with lots of sunlight. However, they are hardy plants that will grow in almost all types of soils as long as it’s not waterlogged. They also perform best in soils that are slightly acidic from pH 6.0 – 7.5.

When growing them in a garden you should know that they emit certain substances that inhibit the growth of particular plants such as potatoes and beans.

The decision whether you should plant sunflower seeds or plants is dependent on where you are planting them. If you are planting them in a region where the planting season is short because of frost, you can consider planting the plants. However, seeds are more common when planting sunflowers.

Planting Sunflower Seeds

  • Make shallow trenches that are about one to two inches deep. When planting in sandy soils, it is preferred to have the trenches at two inches.
  • Plant the seeds at about six inches apart.
  • Cover the seeds and water them for about seven to ten days, the estimated time for them to sprout.
  • Thin the plants to be about two feet apart. Thinning should be done when the first true leaves appear (the second set of leaves). Also, note that if you don’t want the sunflowers to grow to their maximum size you can let them be and not thin them. (they will be shorter and have smaller heads).
  • Water the sunflowers regularly (if need be) especially during their most important period which is about 20 days before and after flowering.
  • You can expect the sunflowers to mature and develop seeds in 80 to 120 days depending on the variety that you planted.
  • It is also important to note that when you want to grow sunflowers for bouquets, not only should you avoid thinning but you should also plant them as close as six inches or even two inches apart in dry places. Furthermore you should skip on any form of fertilizing.
  • Also note that sunflowers attract wild animals such as deer, squirrels, and birds which come to feast on the seeds. Take precautionary measures such as covering the heads with polyspun garden fleece or put up a chicken wire barrier.
  • Sunflowers are hardy compared to a majority of other flowers. However, they can sometimes be affected by insects and diseases. Some fungal diseases include mildews and rusts such as the downy mildew. They can be controlled using a general garden fungicide as well as improving general farming practices like avoiding transferring the disease from the infected plant to the healthy ones.
