1、 Sprout and take root

Carnation seedlings have just begun to sprout new buds, take root downward, absorb nutrients from the loam, and the number of roots increases and develops gradually. The upper leaves will also emerge, and the number of leaves will gradually increase. The temperature during this period is very key. It is more appropriate to keep it at 20-25 ℃. At this time, the seedlings are still thin and weak, so we should pay special attention to maintenance

2、 Continuous elongation

With the action of chlorophyll, the plant will continue to elongate and grow, the internode distance will gradually increase, and the stem will become strong and solid. The root system has been basically mature and the differentiation is relatively vigorous. The expansion speed of leaves is also very fast, the leaves become larger and increase, and the color changes from tender green to dark green. This period is the main period of vegetative growth. Nitrogen fertilizer can be added to promote the rapid growth of plants

3、 Open flowers

Some flower buds on the plant can grow, and with the continuous differentiation, the flowers will open. The number of flowers will gradually increase and gather together one by one. It blooms only once a year. The flowering period is from April to September every year. When the flowering period is over, the flowers will gradually wither and fall
