Longevity flower is a short-day plant, which is sensitive to photoperiod response. After the current dormancy period, plants with cool weather and good growth and development will be treated with short sunshine for 3-4 weeks (8-9 hours a day) and flower buds will appear. You can make a black cover, put it on at 4 pm and open it at 8 am, and it will be fine. In the case of short sunshine, the bud will be pregnant soon, and at the same time, the ideal flower will bloom by strengthening the management of fertilizer and water. In this way, the productive flower fields are treated in batches and the flowering period is staggered.
