What is the sunflower season?

Sunflowers are loved for the beautiful bright color that they add to any landscape. Though there are several different varieties available, these gorgeous plants often bloom during the warm summer and part of the fall season, with mid-summer being the peak season.

Sunflowers are low-maintenance plants and for that reason, getting them to bloom and beautify your garden is not really challenging or involving task. Nonetheless, caution should be observed to prevent pests and diseases from destroying flowers, which in turn reduces bloom cycles.

You’ll at times find that your sunflower plants won’t bloom. If this happens, it is advisable to start over again and plant a different variety. You should also try to ensure that the growing conditions are suitable the next time you plant your sunflowers. To learn more on this, below are five main reasons why sunflowers won’t bloom and the solution to each problem.

Reasons why your sunflowers aren’t blooming

Sunflowers are big and bold plants and this makes it very easy to determine those plants that have flowered and those that haven’t. That said, here are five possible reasons why your sunflowers won’t bloom.

1.    Excessive nitrogen

Application of the correct amount and right kind of fertilizer is one of the most challenging bits of growing sunflowers. According to various research side-dressing sunflowers with an all-purpose slow-release fertilizer added when the plants have numerous true leaves speeds up plant growth and also yields bigger flowers.

That seems good but it is also very important to know that high-nitrogen fertilizers might hinder the formation of production of healthy sunflower heads. A common indicator of nitrogen being the source of your problems is planting with a lot of massive leaves.

If you find that you planted your seeds in soil that is rich in nitrogen or perhaps you accidentally applied a lot of nitrogen, you’ll have to start over. Ensure that you re-plant a fast-growing variety. Also, make sure that the seeds are sown in an area that has not been thoroughly fertilized for at least one or two seasons.

If you find yourself already attached to the foliage-rich stems, you might want to consider root pruning. In some cases, this startles the plant into producing flower heads and eventually blooming. You should, however, be aware that root pruning might turn out to be a complete waste of energy and time.

2.    Insufficient sunlight

Just as indicated in the name sunflowers thrive in the sun. Anything less than 6 hours per day of sunlight can result in your sunflowers not blooming at all. Apart from choosing a planting spot that receives ample sunlight, you should also make sure to plant the shorter varieties in areas where the bigger plants will not throw a shade.

The varieties can be small and cute but they are still sunflowers and so need a lot of the sun’s light. Additionally, the larger varieties need a lot of sun and a well-sheltered spot in order to grow big enough to yield flower heads. Keep in mind that strong winds can result in the toppling of the tall plants before they get to bloom.

To solve this issue, consider growing sunflower container varieties that can be transferred to spots with more light if you do not have a play that receives full sun.

3.    Little growing time

If your sunflowers look tall enough and you have been weeding and watering them, as well as carrying out all other necessary maintenance practices, you might think they are ready to bloom. Do not be deceived by the appearance of your plants. Different sunflower cultivars bloom within a particular established timeframe. Some varieties might even take as long 120 days to bloom.

Don’t worry if you reside in an area with a relatively short growing season. You might still be able to pamper the mature sunflower plants with protection such as row covers during the cold season until they bloom.

Simply put, before purchasing the seeds to grow your sunflowers, it is best to first determine exactly how long the variety takes to mature and flower. You might be surprised by your findings because even various dwarf varieties may require an extra 80 days before they bloom. Hence, if you stay in an area with a limited growing season or maybe you tend to forget about planting your sunflowers until late in the summer, you should go for a variety that does not take a lot of time to bloom.

4.    Insect pests

Insect pests can prevent sunflowers from blooming, and sunflower moths are among the most destructive ones. The adult moths feature dark brown wings that tightly wrap onto their bodies when they are resting. Their larvae resemble gigantic brown inchworms with clear white stripes. Dark insect residue and webs on your sunflower heads are an indication that the larvae are feeding on the plant’s insides.

On top of consuming the flower head tissues, the older larvae also promote the Rhizopus fungi that cause the rotting of the flower heads prior to and during blooming.

Though parasitic flies and wasps at times tend to keep these annoying moths on bay, which might not happen in a home garden. If the sunflower moths get out of control, it is best to destroy the affected flower heads by burying or freezing them.

Other common insect pests include sunflower midges, which also feed on the flower heads. If you have experienced midge issues in the past, look for sunflower varieties that are tolerant or resistant to these insect pests.

5.    Deer

Deer are known to cause lots of garden damage. They might also be the reason why your sunflowers are not blooming. If you have grown a bigger culinary sunflower variety, you should know that it only yields one flower head per stalk. If a deer happens to chomp it off, the plat will not blossom at all.

If deer often visit your area, you can easily keep them away using a tall wire barrier. Also avoid growing single stalk flowers and instead try growing multi-branching sunflower varieties such as ‘Evening Colors’.

Final remarks

The sunflower season is summer. It is when big sunflower heads look their best. If it is sunflower season in your area and your sunflowers are not blooming, there is a problem.

The problem could be lack of enough sun, lack of time, excess nitrogen, deer attacks, or pests. This post discussed these problems and gave a solution to each problem.
