The flowering time of tulip is from March to may, but it can be changed by controlling temperature. If we put it in 34 ℃ for one week in June July, and then in 17 ℃ for two months, we can promote flower bud differentiation. After planting in September, it will bloom in December. If the flower bud differentiation immediately put in 9 ℃ environment for a week, wait until September after planting, the next year in February can bloom.
1. Temperature: tulip flower bud differentiation stage, the temperature should be controlled at about 17-23 ℃. If the temperature is higher than 35 ℃, the differentiation of flower bud will be inhibited, which will lead to unfavorable flowering. In addition, low temperature will also lead to non - flowering and other conditions, it is necessary to move it indoors in time.
2. Sunshine: when tulip is germinating, light note can inhibit the growth of flower bud. So to timely shade, in addition to the ball can also be planted a little deeper, which is conducive to flowering.
3. Watering: watering should be reduced properly during flowering. At this time, its demand for water is limited, too much water will hinder the root respiration, leading to its decay or even death. Watering can properly increase the number of times, control basin soil is not too dry.
4. Fertilization: stop fertilization during flowering to avoid damaging roots. After the flower, liquid fertilizer should be applied in time to supplement nutrients for the seed ball.
