What flowers are suitable for planting in autumn?

1, trollius chinensis can bloom all year round. A flower can last 8-9 days. Water should be reduced after flowering to prevent the branches from growing vigorously. If there is too much water, the drainage is not good, the roots are easy to wet and rot, and the whole plant withers and dies. Sexual preference is mild, and the climate is not resistant to cold and heat. The optimum temperature is 18 to 24 degrees Celsius. It can tolerate short-term 0℃ and likes warm and humid, and the wintering temperature is above 10℃.

2. Corydalis tricolor is usually planted in early September. It is required that the soil in the seedbed or sowing basin must be well drained. After sowing, cover the soil twice as much as the seeds, pour water with a fine watering can and put it in a well-lit place. Cold-tolerant, cool-loving and sunny, it develops well under the conditions of daily temperature 15-25℃ and night temperature 3-5℃. Avoid high temperature and stagnant water, cold and frost.

3, calendula, self-sowing, fast growth, cold tolerance, no choice of soil, especially loose, fertile, slightly acidic soil. Autumn sowing is often carried out after the middle and late September. Living habits: I like sunny environment, have strong adaptability, can withstand the low temperature of -9℃ and am afraid of hot weather. Don't choose soil, loose, fertile and slightly acidic soil is the best, which can sow by itself, grow fast and be cold-resistant, so don't choose soil. Resistant to barren and dry soil and cool environment, it grows well in sunny and fertile areas.

4, bellflower, the seeds are small, the soil should not be too thick, the germination temperature is 20-24 C, and it can also be divided into plants or cut. The environment is required to be warm in winter and cool in summer, with plenty of sunshine, good ventilation, no tolerance to dry heat and cold, and like deep and fertile neutral soil with good drainage, which can also grow normally in slightly alkaline soil.

5, snapdragon, can be sown in spring and autumn, autumn sowing seedlings grow stronger and bloom more luxuriantly than spring sowing seedlings. Emerge 7~ 10 days after autumn sowing. When conditions permit, soaking seeds with 50~400 mg/L gibberellin solution can improve seed germination rate.
