growing environment
Tulips are native to the coastal areas of China, Central Asia and Turkey. The unique Mediterranean climate forms the characteristics that tulips adapt to wet and cold in winter and dry and hot in summer. They have the characteristics of dormancy in summer, rooting in autumn and winter, sprouting new buds but not unearthed. After the low temperature in winter, it begins to swell and grow in early February of the following year (the temperature is above 5℃), forming stems and leaves, which bloom in March-April. The suitable temperature for growth and flowering is 15 ~ 20℃. The flower bud differentiation is carried out during the storage period when the stems and leaves become Yellowstone. The bulbs are dug out of the pot and placed outdoors in cold weather. The optimum temperature for differentiation is 20-25℃, and the highest temperature should not exceed 28℃.
Tulip is a long-day flower, which enjoys a sunny and sheltered climate. It is warm and humid in winter and cool and dry in summer. It can grow normally above 8℃ and generally can tolerate the low temperature of-14℃. Strong cold tolerance. In cold regions, bulbs can overwinter in the open field if there is thick snow, but they are afraid of hot summer. If summer comes early and it is very hot in midsummer, it will be difficult for bulbs to spend the summer after dormancy. It needs a kind of slightly acidic sandy loam rich in humus, loose and fertile soil and good drainage system. Avoid alkaline soil and continuous cropping.
