Tips for planting flowers:
plant
Potted Trollius chinensis should be mixed with 7 parts humus soil and 3 parts garden soil, and appropriate cake fertilizer or other organic fertilizer should be added as base fertilizer. Generally, plants that have been cultivated for 3 years need to be updated, because the old plants are not prosperous and there are not many flowers.
Fertilize soil or land
Fertilization at seedling stage can be 10 day 1 time, and fully decomposed cake fertilizer and water can be applied. It is advisable to apply less chemical fertilizer in the future, and generally apply 1 times thin fertilizer every 20 days. However, fertilizer and water can be applied every 7- 10 days before flowering to promote flowering. Fertilization must be appropriate, especially too much nitrogen fertilizer, which will cause the consequences of only long leaves without flowering, thus affecting the ornamental effect.
water
Usually, we should pay attention to watering in time, because there are many pulp inside the branches, so we need enough water throughout the growing season to maintain a high air humidity. Don't let the pot soil be too dry or wet, and the leaves will turn yellow easily if they are too dry; Too much wet water tends to rot the roots.
Temperature, light
The growing season should be placed in a sunny and well-ventilated place. When the temperature is high in summer, you should shade yourself properly.
Indoor activities in winter, curing in the sunny place, keeping the room temperature at 10- 16℃, controlling watering and properly applying 1-2 times thin fertilizer can make it grow and develop normally. When cultivating Trollius chinensis indoors, attention should be paid to poor ventilation, and aphids on the stems and leaves should be prevented in time.
Plastic trimming
In order to make the leaves of Trollius chinensis rich and beautiful, it is necessary to set up a bracket with fine bamboo and tie the vines evenly on the shelf, so as to make the leaves face in one direction as far as possible. Before putting it on the shelf, the core should be removed, leaving the main stem and thick side stem to promote its germination and achieve the purpose of flourishing leaves and flowers.
Why don't lilies grow in the hot season?
1. The suitable temperature for lily stem rooting (an important root system that absorbs nutrients above bulbs) is about 12 degrees. Generally, the soil temperature (not equal to air temperature) in spring and autumn is close to this range. The development of stem rooting directly determines the flowering quality and rejuvenation.
2. Most lilies are not resistant to high temperature, and their dormancy temperature is extreme. If the temperature stays above 35 degrees for a long time, especially for Dongbei, it is easy to cause forced dormancy. Lily can't stand extreme high temperature, especially in bud stage and flowering stage. The high temperature during flowering will make the flowers wither quickly. Lily rots easily in hot, humid and sultry weather.
