How to plant tulips
In order to make the ground-borne tulip plants robust, colorful, moderately long pedicels and large flowers, attention must be paid to:
① planting site selection and preparation. The planting site should be in the shelter from the wind and the sun, and the groundwater level is 50-70 cm. The soil is required to be loose and fertile, so it is necessary to turn the soil deeply, such as if the soil quality is not good, replace the original soil of the planting layer with culture soil, and apply the base fertilizer mixed with rotten organic fertilizer and a little superphosphate.
Selection and treatment of ② balls. The new bulb must grow well and have a diameter of more than 3.5 cm, otherwise it will bloom poorly, without damage, dark brown spots or mildew, and no insect pests. Peel off the yellowish to brown membranous pseudoscale of the bulb before planting, soak the bulb with a mixture of 1500 times of dicofol and 3000 times of carbendazim for 10 minutes, then rinse with water and dry for seed.
③ planting depth. Planting should not be too deep or too shallow. Generally, the soil cover is about 2 / 3 of the height of the corm. If the bulb is too deep, the bulb is easy to rot and less new bulbs are formed at the same time; if it is too shallow, the root system is vulnerable to freezing and drought damage. In winter, the north needs to be covered with grass curtains and other things to prevent the buds from freezing damage, and uncover them in time after thawing in early spring.
④ fertilizing and watering. Water the bulb once after planting, and then keep the soil moist. More water is needed when stems and leaves grow and buds appear in the next spring, which is particularly important for cut flower cultivation. Avoid stagnant water when it rains. Dilute pancake fertilizer and compound fertilizer should be applied several times during the growth period, usually liquid fertilizer based on nitrogen fertilizer is applied once after leaf spreading; liquid fertilizer based on phosphorus and potassium is applied once a week after bud emergence and stem extraction, and 0.1% potassium dihydrogen phosphate liquid fertilizer is sprayed once before flowering; fertilizer is applied 2 times and 3 times after flowering, while watering times are reduced and the soil is not dry or wet, so as to promote the growth and enrichment of new bulbs.

How to make tulips blossom
Tulips are planted in the natural environment and generally bloom from March to May. In order to make tulips blossom during the Spring Festival, the following technical measures should be taken. The choice of planting balls: in October, choose disease-free insects, enrich the enlarged bulbs, and remove the brown outer skin. Disinfection of seed balls: before low temperature treatment, soak in the 800 times solution of 75% chlorothalonil wettable powder for 15-20 minutes, then dry naturally. Low temperature treatment of bulbs: tulips grown in natural environment have a natural dormancy process, in order to make tulips blossom earlier in the Spring Festival.

Let the tulips blossom again
Tulips bloom from March to May every year. If you want to make it blossom again next year, you can maintain it in the following ways. After the flowers wither, cut off the pedicels and plant the leafy bulbs together in the pot (those with a small courtyard can also be planted on the ground). When planting, you should first add base fertilizer, preferably bean cake crumbs and bone powder, to promote the growth of split bulbs, and then apply thin fertilizer 2 to 3 times, usually need to be watered to prevent drying. When the tulips enter the semi-dormant period in early summer, the bulbs must be dug out of the basin and dried and stored. Stay until September to
