After Tomb-Sweeping Day in the following year, the flowerpot can be placed outside the window, and it needs to be maintained in the window in case of cold current.

Sunflower has a name: the sun, as its name implies, is a flower that grows towards the sun, so the most important thing is to have enough sunshine to help it grow. Light is also a condition that it must meet when it blooms. If the sunflower is placed in a dark and humid place, it will not bloom or spend less, and many people's sunflowers will not bloom, which is one of the reasons.

Sunflowers are not afraid of strong light. The more sunshine, the better the flowers bloom. Sunflower is notoriously barren-tolerant, but it is a flowering plant after all. If there is too little fertilizer, there will be fewer flowers. After pruning, apply some nitrogen fertilizer to it to promote the growth of new branches In the later stage, phosphorus and potassium fertilizers are mainly used to promote flowering and protect fetus, and they are applied once every half month to one month.

When the temperature drops in autumn, the transpiration of soil and plants will slow down, so watering times should be reduced to avoid water accumulation and root rot.
