Is a sunflower suitable for a large or small pot?

Should I use a large or small pot for sunflowers?

When choosing a flowerpot for sunflowers, you need to choose a pot according to the size of the plant. If the plant is larger, you need a large pot. If the plant is smaller, you can use a small pot first. Generally, a 15-20 cm flowerpot is enough for the growth of plant seedlings. When it grows bigger, you can change to a 20-40 cm flowerpot. However, its growth ability is limited, so don't use a pot that is too large.

Requirements for sunflower pots

Determine the pot to be used according to the size of the sunflower. It is best to use a deeper and larger pot for sunflowers with large roots, and it is best to use a smaller and shallower pot for sunflowers with small roots. During the later stage of cultivation, you can replace the corresponding potting soil according to the size of the plant. In addition, sunflowers are prone to root rot, so do not use a pot that is too deep, otherwise there will be too much water accumulation, which will cause root rot.

Key points for sunflower potted plant maintenance

1. Thinning

For potted sunflowers, since the planting range is limited and sunflowers are a plant that can grow very lush, they need to be thinned out and given enough living space to grow, otherwise they will be restricted and the sunflowers will not grow well.

2. Fertilization

The flowering period of sunflowers is very long and they grow lushly. In order to make it grow faster and brighter, you can fertilize it. The fertilizer is mainly nutrient solution or phosphorus fertilizer. Fertilizer can be applied about once every half a month, but the amount of fertilizer should be controlled to avoid fertilizer damage.

3. Lighting

Sunflowers love sunlight, so they need plenty of sunlight to grow, so they should be planted in a well-lit place. The higher the light intensity and the longer the time, the better they grow, which can also enhance their ornamental value.

4. Watering

Sunflowers are drought-resistant, but they consume a lot of water during the peak growing season, so they need to be watered in time. Each time they are watered, they must be watered thoroughly without accumulation of water to avoid root rot. In addition, pay attention to water control in winter and keep the soil slightly dry, which is conducive to wintering.

5. Temperature

Sunflowers like a warm environment, and the suitable growth temperature is between 20-30 degrees. They are not cold-resistant, so they need to be moved indoors in the winter when kept in pots, and the temperature should be controlled above 10 degrees to avoid frostbite. In addition, they need more ventilation during the high temperatures in summer, and should not be placed in an airtight place, otherwise they will be easily infected by diseases and pests.
