2. After the flower fails, cut it 2-3 cm below the flower. Be careful not to cut it too long, keep the leaves, apply a little fertilizer and water it normally. Pay attention to rainy days, control water quantity and avoid root rot. After two months of strong roots, when the leaves and stems become Huang Shi, dig out the bulbs before the rainy season.
Be careful not to hurt the bulb, remove the leaves and stems from the upper part of the bulb, and put the bulb in a cool place. It is best to find semi-humid sand and a big box with a plastic bag at the bottom to prevent leakage. Bury the light bulb inside. If the sand is dry, spray a small amount of water after burying it. Don't use too much water, put it in an open place to prevent the light bulb from vomiting. In late autumn, it was buried by pouring ice water.

? After the tulip blooms, the new bulbs in the underground part develop rapidly, and the mother bulbs as seed bulbs disappear. Therefore, tulips should be cut off immediately after withering, and bulbs with leaves should be planted in pots (small yards can also be planted on the ground).
When planting, base fertilizer should be added first, and it is best to use bean cake crumbs and bone meal to promote the growth of split bulbs. The new bulb is developed from the lateral buds between the axils of the fleshy scales of the mother bulb, and the lateral buds germinate when the terminal buds of the mother bulb form flower buds. During the period of promoting lateral bud germination, thin fertilizer should be applied two or three times, and water should be used at ordinary times to prevent drying. ?
In summer, tulips enter semi-dormancy. At this time, small bulbs should be dug out of the pot, dried and stored. According to the growth law of apical dominance, the first lateral bud below the apical flower bud is the most robust and can become a good flower ball, and the order of the lateral buds below is weakened. Wait until September ~ 10, then put the finished flower balls back in the basin and apply base fertilizer.
In winter, plants planted in the ground can overwinter in the open air, and potted plants should be placed in sunny and warm places outside. The soil in the pot should be dry and wet, so that it will grow new leaves from the soil after the spring next year, during which it will be fertilized twice and will bloom again in March and April.
