When are tulips in full bloom?

Tulips usually bloom from March to May every year.

According to the season, it is spring now. There are many varieties of it, and the specific flowering time will be different due to different varieties and different climates. Some meetings will be held earlier, around March, and some will be held later, only in May. When flowering, the flowers are colorful and varied, beautiful and have strong ornamental value.

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.

growing environment

1, temperature: Tulip is extremely cold-resistant, and can withstand the low temperature of -35℃ in winter dormancy, but it can also be cultivated in the open field in areas with the lowest temperature of 9℃ in winter. If the low temperature below 9℃ lasts for more than 16 weeks, it will break the dormancy of bulbs and make them grow and develop normally. The suitable temperature for germination is 9 ~ 13℃, and it basically stops below 5℃.

The optimum temperature for growth and flowering is 15 ~ 20℃. Above 20℃, the leaves grow white. The formation temperature of new pellets is about 20℃. The optimum temperature for flower bud differentiation is 20 ~ 30℃, and flower bud differentiation is inhibited when it exceeds 30℃, but different varieties have slightly different temperature requirements.

2. Illumination: Tulips are neutral plants in the daytime, and the requirements for the length of sunshine are not strict. Likes light and is slightly tolerant to semi-shade, but the light intensity is too low, which weakens photosynthesis and leads to poor growth.
