Can sunflowers be placed indoors?

1. Can it be placed indoors?

If it is a flower arrangement, of course it can be placed indoors, but it needs to be replaced frequently. If it is a potted plant, try not to place it indoors. It itself has no adverse effects, but after being placed for a long time, it will grow many small insects, which is not good for the environment. It also likes sunlight. If it is often placed indoors, it will grow wildly and its leaves will turn yellow, but it will not grow flowers, so it is best to place it on the balcony outside the house.

2. Daily maintenance

Before the flowers bloom

1. It can grow up to 3 meters high. It belongs to the sunflower genus. The whole body includes roots, stems, leaves, flowers and fruits, a total of five parts.

2. It likes relatively sufficient light and has a strong phototropism. If the sun is strong, it will not grow too tall and the seedlings can grow strong.

3. After it sprouts, the soil should be kept moist at first. After it grows two true leaves, it should be kept alternately wet and dry. When it grows 4 or 5 true leaves and the temperature is between 15 and 30 degrees Celsius, it should be fertilized.

4. Before its flowers appear, add nitrogen fertilizer, and after the flowers appear, add phosphorus and potassium fertilizer. In spring, you should reduce the frequency of watering, and increase the frequency in hot seasons, and make sure to water thoroughly each time.

Long flowering period

1. If it has already grown flowers, there is no need to add fertilizer. If you apply fertilizer during the flowering period, it is likely to have a negative impact on its flowers.

2. It is best to wait for a while and wait until the flowers have faded before considering fertilizing. You can add more phosphorus and potassium-rich compound fertilizers to make the fruits mature faster.

3. After its flowering period is over, the outermost yellow petals will fall off by themselves. If there are no insects to pollinate it on the flowering day, you can do it artificially. Wipe its flower disk with a soft towel or cotton swab every day to get seeds.

4. It usually blooms for ten days. The first day is called the initial flowering period, and days 2-6 are the peak flowering period. This period is the best time for pollination. After the seventh day is the end of flowering, and the number of flowers gradually decreases. At this time, pollination will not be very effective.

5. Wait until its involucre turns yellow before you can pick it. At this time, the petals have fallen off, the seeds are full, and it is fully grown.
