How to make the Dutch arrow bloom longer?

The method of Dutch arrow flowering for many times:

1, take a strong arrow and give it enough light in summer. Don't rush to move indoors in autumn. At night, it can be in an environment not lower than 2℃-5℃, with sunshine during the day and less watering. When it shows buds, 1-2 buds remain on each leaflike stem. When the buds grow to 6-8 mm, put them indoors in the shade at 20℃ until they bloom. The flowering period is 4-5 days. If there is no bud in late autumn, move it from outdoor to indoor or balcony, and continue to stimulate it with low temperature, drought and light, and it will bloom. It blooms for the first time around the Spring Festival.

2. After the first flowering, put it in a sunny place indoors 10- 15 days, and give some fertilizer to make the withered plants full. After that, it is not difficult to open the flowers for the second time by placing them in a place without heating and then stimulating them with low temperature, drought and light.

3. The low-temperature light stimulation of the third flowering can be placed outdoors or on the windowsill or balcony where the window is opened, so that the cold wind can blow at night.

4. The key points of making the arrow blossom many times a year are: using low temperature, drought and light stimulation to promote bud differentiation; Then use water, light and warmth to promote its flowering; Keep flowering for 4-5 days, without strong light. After the flowers bloom for three times, give them light, water and fertilize to make them grow sturdily.

If the plant can't rejuvenate, the old branches can be cut off in autumn, placed in a low-temperature light environment for more than 5- 10 days, then inserted into the soil, and cultivated according to the above method, and flower buds can appear around the Spring Festival. Plants that bloom twice a year can ensure rejuvenation.
