Where is chrysanthemum suitable for planting? North or South? Bad environment?

Chrysanthemum is suitable for planting in north and south. Chrysanthemum has strong adaptability, likes cold and is relatively cold-resistant. The suitable growth temperature is 18-2 1℃, the highest is 32℃, and the lowest is 10℃. The low temperature tolerance limit of underground rhizomes is generally-10℃.

The lowest night temperature at flowering stage is 17℃, and it can be reduced to 15- 13℃ at flowering stage (middle and late stage). I like plenty of sunshine, but I also tolerate shade a little. More resistant to dry, the most taboo waterlogging. I like sandy loam, which is located in Gao Qian, with deep soil layer, rich humus, loose fertility and good drainage.

It can grow in slightly acidic to neutral soil, and the pH value is 6.2-6.7. Avoid continuous cropping. Autumn chrysanthemum is a long-night plant, and its stems and leaves grow nutritionally under the long sunshine of 14.5 hours every day. Darkness of 12 hours per day and night temperature of 100 degrees Celsius are suitable for flower bud development. But different varieties have different reactions to sunlight.
