When should flowers be brought indoors in autumn, and what preparations should be made before sowing seeds?

Flowers should be brought indoors at the right time in autumn

In autumn, as sunlight gradually weakens and temperatures drop, flowers should be brought indoors in good time so they can adapt to the changing weather and be protected from frost damage.

Generally, when the average daily temperature drops to around 5°C, it is suitable to move flower pots indoors. Depending on the variety, flowers are moved indoors at different times. Tropical flowers such as jasmine, Milan (Aglaia odorata), hibiscus, Michelia figo, citrus, asparagus fern and cacti should be brought in earlier; flowers such as osmanthus, pomegranate, Chinese rose, grape, dwarf lilyturf and pines and cypresses should be moved indoors before Frost's Descent; dahlias and chrysanthemums are not afraid of the cold and bloom more abundantly the later it gets in autumn, so they can be moved indoors later. However, these flowers are also vulnerable to frost, so they should be moved indoors before the frost arrives, and their pots placed in a sunny spot indoors so they can continue to bloom. If Chinese roses need to go dormant for the winter, they can be left outdoors for a longer period, and only moved into a vegetable cellar or placed in a cool spot indoors after their leaves fall; if you still want to enjoy them in winter, they must be moved indoors in advance.

There needs to be a transition when moving flowers indoors. No flower should be moved indoors abruptly, let alone watered heavily or placed in a poorly ventilated spot indoors, because this will cause the leaves to drop and the roots to rot, leading to death. In the early stage after flowers are brought indoors, they should be taken out at noon each day to get some sunlight, and after 7 to 10 days they can be placed in a fixed spot indoors. Potted flowers should be placed in a location suitable for their growth; for example, sun-loving flowers should be placed on a sunny windowsill, shade-loving flowers should be kept farther from the sunlight, and some flowers should not be fixed in one place but moved frequently to follow the sunlight.
