Growth habit

Hundred-day chrysanthemum likes warmth, cold tolerance, sunshine, fear of heat, strong sex, drought tolerance, barren resistance, and avoid continuous cropping. The root is deep and the stem is hard and not easy to lodge. It is suitable to grow in fertile and deep soil. The suitable temperature during the growing period was 15-30 ℃.

Water and fertilizer conservation

In addition to the seedling stage, it needs timely watering, in addition, it is generally not suitable for more watering. But the summer period needs to be watered frequently to keep the soil moist. Otherwise, it will cause small leaves and yellow flowers, poor color and luster, and the ornamental value will be greatly reduced. During the whole growth and development period, it is usually enough to chase three times of thin fertilizer. The mixed fertilizer of chlorine and potassium was mainly used in the seedling stage, the phosphorus fertilizer was the main fertilizer in the bud stage, and the compound fertilizer of chlorine, phosphorus and potassium was applied in the first ten days of September. If you fertilize too much, the plant is easy to overgrow and cause lodging.
