The sunflower is a very beautiful flower that can be grown both in the house (in pot) and outside (in the garden).
However, just like growing other plants, the sunflower also requires specific care to always stay healthy.
In most cases, it is not necessary to prune the sunflowers often, unless you are growing several in the same space and can then serve to prevent the flowers from stealing the space of each other.
Thinking about planting sunflowers and have doubts about how you can take care of these flowers? Find out in this article what to do to take care of a sunflower:

What is the best place to plant a sunflower?
You have two options when planting sunflowers, pots and the garden itself, but each requires different care:
1. In the vessel
If the idea is to grow the sunflower inside the house or apartment, the pot is the best option. In this case you must choose a large vase and invest in dwarf or smaller plants.
Sunflowers do not cope well with relocation, so plant directly in the pot where you want the flowers to stay.
It is also important that you leave the vase in a place that receives direct sunlight, because the flowers need this to develop.
2 In the garden
In the garden already possible to invest in sunflower species that reach higher heights. Besides that you can plant more than one. Always taking care that they are not too close to each other.
Prepare the earth (this flower likes neutral pH, although it is quite tolerant of variations) and dig a hole two to four inches deep. Plant the seeds and water.
When sunflowers are born it will be necessary to prune them, if they are very close to each other. You should also keep the land always moist, but never soaked.
Time of planting and flowering
Sunflowers can be planted all year round, there are no restrictions as to the planting season. However, if you opt for warmer periods such as spring and summer you will see the flowering period arrive faster.
The flowers usually appear between spring and summer, yet depending on the time they were planted and the temperature, they may appear at other times of the year. The main one is that the temperature varies between the eighteen and thirty degrees, considered ideal for the flowering.
Sun exposure and ideal temperature
As you may have heard, sunflowers accompany the movement of the sun. Which means they like to be exposed to sunlight.
If being grown in the garden will certainly be exposed to the sun, now if you are taking care of the flowers inside the house or apartment, make sure they receive direct sunlight at least six hours a day.
As for the temperature, these flowers prefer the warmer climates, so much that they are able to withstand heat very close to 40 degrees. So the ideal is to take care not to be exposed to the cold, especially if you live in icy regions.
Sunflowers do not survive temperatures below five degrees and it is recommended that they be exposed to a minimum of ten degrees and not less so to ensure that they grow healthy.
How Irrigation Works
These flowers do not like very dry or extremely soggy soil. Therefore, it is interesting to observe how the land is and do the watering to keep it moist.
Adult plants can cope with periods of drought, but too much watering will kill the sunflowers. If the flower stays in the garden and it has rained frequently, it may not be necessary to water.
Now if you stay indoors in a vase, check daily how the earth is. If it is damp, avoid watering, if it is starting to dry it is necessary to water the plant.
Sunflowers do not have much prejudice about the soil. They may even survive pH variations (more acidic or more basic). Still, the ideal is to plant them in soil of neutral pH and with several nutrients.
Fertilizing the soil is not recommended unless the idea is to get very tall flowers. And in this case, the recommended fertilizers are those based on nitrogen.
Another important aspect in relation to the soil is the humidity. It should be a space that absorbs water without accumulating and also does not reek so easily.
The soil should also be soft, loose and light, to facilitate planting.
Pruning of sunflowers
Most of the time you do not need to prune the sunflowers, unless your goal is to harvest them. That's because they are plants that bloom only once a year.
Pruning is recommended only for those with many flowers planted together and growing in groups. In this case, pruning is ideal to prevent one sunflower from knocking down the other.
If you need to prune it is recommended to do this only twice a year, usually in late spring or early summer.
Another interesting tip in relation to pruning, also recommended to those who are growing various flowers is to remove those that have become smaller and weaker. This should be done when the plant reaches approximately 8 cm in height.
So you increase the space between the sunflowers and ensure that only those who will remain strong and beautiful remain planted. This space created by the removal of weaker plants also helps prevent one sunflower from knocking down the other.
Protection against pests
To protect your sunflowers from pest attack it is interesting that:
1. Remove pests
Sunflowers planted in the garden are more exposed to this situation. The plant is quite resistant to pests, but is usually the victim of a moth, which lays its eggs in the middle of the flower.
If this happens it will be necessary to remove the eggs one by one.
2. Apply fungicide
Another common situation is the appearance of mold and rust, caused by fungi. To prevent, just apply a little fungicide.
3. Put screens on the sunflowers
Birds also like these plants very much, even feeding on them. If you want to prevent this from happening you can protect the flowers by putting screens on them.
Still, this is only recommended if you notice the appearance of many birds attacking the flowers. Otherwise, you do not need to use the screen.
Now you already know how to grow and care for sunflowers. As you can see, they are plants that do not require great care and survive well in various environments.
The main thing is to ensure that they are exposed to the sun and take care of the watering, since the plant does not like very wet soil.
