Everything about chrysanthemums

There are more than 30 kinds of chrysanthemums, and 17 kinds are native to China, mainly including: wild chrysanthemum, chrysanthemum, chamomile, chrysanthemum, chrysanthemum and so on. It is a perennial herb. I like cold, cold, growth temperature 18-2 1℃, underground roots are drought-tolerant, and waterlogging is the most taboo. I like loam with high terrain, deep soil layer, rich humus, loose and fertile soil and good drainage. It can grow in slightly acidic to slightly alkaline soil. And Ph6.2-6.7 is the best. As a short-day plant, it grows nutritionally under the long sunshine of 14.5 hours every day. Darkness above 12 hours per day and night temperature of 10℃ are suitable for flower bud development.
