How to make potted tulips bloom at New Year's Day and Spring Festival
Grow tulips using the forcing method. After planting the bulbs, place them outdoors in a cool spot and keep the potting soil neither dry nor wet, until 1~2 months before the planned flowering period, then move the pots to a temperature of 5~10°C; after the leaves emerge, move them to 15~18°C in a sunny spot, and increase watering and fertiliser, and they will bloom at New Year's Day and Spring Festival.
How to make tulips bloom earlier and prolong their flowering
To make tulips bloom earlier, the potted method is mostly used, with the following measures:
① Temperature treatment of the bulbs. After lifting the bulbs, select plump, large bulbs free of pests and diseases, dry them slightly in the shade, then first treat them at about 34°C for about 1 week, then store them under ventilated conditions at 20°C for 1 month so that flower bud differentiation is completed, then move them to 17°C for 1~2 weeks, after that place them in a cold storage room at about 10°C for about 1 month, then transfer them to 1~3°C for cold storage for 5~6 weeks; at this point the base of the bulb has a horseshoe-shaped swelling, indicating a state about to root, and they can be potted up. After planting, keep the growing temperature at about 14°C, and after buds appear, raise the temperature to about 18°C.
② Strengthen fertiliser and water management. See "How to scientifically grow potted tulips".
③ Increase the lighting time. After the tulip flower buds appear, they can be illuminated with lights to extend the lighting time. This can make tulips bloom earlier, adding to the lively festive atmosphere of New Year's Day and Spring Festival. If you want to prolong the flowering period of tulips, move them after flowering to an environment of about 12°C for growing.
