How to raise a blue witch?

The blue witch is a kind of flower that is very popular with lovers, but how to raise it? Let's have a look!

First, how to raise the blue witch?

Trim the blue witch properly and wash and disinfect the roots with a small amount of potassium permanganate solution. Then insert the vase with a height of about 15cm, and cut off the leaves and flower branches that have not been submerged, so as to avoid the pollution caused by flower and leaf rot. Finally, add ground aspirin to the water for about a week, but change the water every two days and place it in a sunny environment, which can promote the normal growth and development of the stem.

Second, the production method of the blue witch

The more formal "blue demon" begins to dye in the growing period of flowers, and the color can be uniformly attached to the petals and looks more natural.

Use a harmless dye and dye aid to make a colorant, and when the white rose (or white rose) is nearing flowering, start watering the flowers with dyes, allowing the flowers to absorb water and inhale the colorant to achieve dyeing.

Most vendors directly dye ordinary white roses blue after picking, the color is unnatural and easy to fade, and there is a blue witch covered with blue gold powder dye.

Although the requirements of climate and soil for the flowers used in the production of blue witch are not strict, it is more suitable for loam which is loose, fertile, rich in organic matter and good in slightly acidic water.

Flowers like a warm, sunny, well-ventilated environment. The optimum temperature of most varieties is 15: 26 ℃ during the day and 10: 15 ℃ at night. Dormancy occurs when the winter temperature is below 5 ℃. Some varieties can withstand the low temperature of-15 ℃ and the high temperature of 35 ℃, and when the summer temperature is more than 30 ℃, the plant will enter semi-dormancy and grow poorly, although it can also conceive buds, but the flower petals are few, the color is dim and dull, and it loses its ornamental value.
