1、 Sowing season

Tulips are sown in autumn. As a bulbous plant, it needs a low temperature period for vernalization. If the temperature is always high, the development of the plant will be affected. After sowing in autumn, this condition can be met in winter. If it is sown in spring, plant growth will stop once summer comes, and it is usually too late to bloom

2、 How many days does it take to blossom

Tulips are bulbous plants, so they are mostly planted with seed balls. Generally, the diameter of seed balls is more than 5cm before flowering. It takes 45-60 days from planting to flowering. It should be noted that it often takes four years to grow to the size of flowering when sowing from seeds

3、 How to promote flower growth

1. Sufficient light: tulips belong to long sunshine plants, so only enough light can make its flower buds differentiate. If the environment is too dark, the plants will not bloom, but may also grow in vain, resulting in loose plants and unsightly appearance. Usually put it in the sunny place and let it receive light all day

2. Proper fertilization: Tulip flowering needs to consume nutrients, and proper fertilization can also promote plant flowering. Generally, nitrogen fertilizer is not used for fertilization. Although it is helpful for the growth of branches and leaves, it will inhibit flowering. Phosphorus and potassium fertilizer is usually used, which can promote flower growth

3. Temperature control: tulips have high requirements for temperature. High or low temperature will slow down their growth and affect plant flowering. Usually, the temperature should be controlled between 15-18 ℃. If it exceeds 35 ℃, the differentiation of flower buds will be inhibited. At this time, it needs to be cooled properly. You can spray water on it and maintain good ventilation
