Tulips bloom in March to May each year, if they are placed in June to July to 34 ℃ high temperature for a week, and then refrigerated, the year in September sowing, December will be able to bloom. In the tulip bud differentiation period need to control the ambient temperature between 17 to 23 ℃, in the light is too strong, need to build a layer of shade net above the seed ball to weaken the intensity of light.

Tulips generally bloom in March to May each year, but can be adjusted to change the flowering period by adjusting the temperature, if you place it in June to July to 34 ℃ for a week of high temperature, and then placed in 17 ℃ of the environment to store 2 months, you can promote the differentiation of the flower buds, sowing seeds in September, December will be able to bloom.

In the tulip bud differentiation period, the need to control the ambient temperature between 17 to 23 ℃, the temperature more than 35 ℃ will inhibit the buds to differentiate, resulting in tulips can not be normal flowering. Low temperatures can also prevent tulips from flowering properly, and they need to be moved to warmer indoor care in a timely manner.

The tulip has a high demand for light during bud differentiation, and strong sunlight will inhibit bud differentiation and growth, so you need to build a layer of shade netting above to weaken the intensity of light. And when planting can be buried in the depth of the seed ball a little deeper, so that the tulip can better flowering.

During the flowering of tulips need to strictly control the amount of watering, during this period of time it is less water needs, watering too much will inhibit the respiration of the roots, so that the tulip root system appears to rot. Therefore, each time you need to wait until the potting soil is dry and white in the appropriate watering and moisturizing, so that the potting soil in a slightly moist state.
