You can't grow a real black rose.

The black flowers you see every day are actually crimson or dark purple flowers that are close to black, that is, what you call "red black, purple black" in daily life, black peonies, black tulips, black chrysanthemums, and black roses.

Black flowers are very rare in nature, especially true black flowers do not exist, the main reason is that the flowers of the black liquid bureau can absorb all the light waves in the sun, and the temperature rises quickly in the sun, and the flower tissue is easily damaged.

Therefore, we often see red, yellow, orange, white and other colored flowers, which is due to the fact that these flowers can reflect the red, orange and yellow light waves that contain more heat in the sun, so as to avoid burning the delicate flowers, which is a kind of self-protection of plants.

The solution to the black spots on the leaves of the rose is to use 75ml of quick net, 15ml of garlic oil, 25ml of foliar fertilization, 15kg of spray mixed with water, once every 3 days, and use it 3 times in a row.

Rose black spot is an important disease of roses and moons, and it is also one of the common diseases, and the damage is serious. It mainly damages leaves, petioles, twigs, peduncles and flowers. The leaves are infected with small brown spots in early spring, which are purple-brown to black-brown, round or irregularly shaped lesions after expansion, with a diameter of 2-15 mm or larger, radial edges, and sometimes the lesions cover a large area of surrounding mesophyll tissue and turn yellow.

There are so-called black flowers in the world, but they are not pure black, and pure black moon seasons do not exist, at most they are black and red, and it is actually very strong red. . .

The color of the flower depends on the anthocyanins, which are water-soluble pigments that change color with the acidity and base of the cell fluid. The cell fluid is reddish if it is acidic, and it is bluish if it is alkaline. The absence of black is mainly due to sunlight, if the flowers are black, then they will absorb the energy of all wavelengths of sunlight, which is easy to be burned by strong sunlight, so natural selection determines that black flowers are very rare.

Yes, you have to be careful.

Melasma?

If so, pay attention to ventilation, moisture reduction, and spray fungicide.

You can go into our greenery and ask about the world.

Most of them are dyed, but some of them are true, but I prefer the white and blue flowers and the green cherry blossoms.

There are three varieties of so-called black roses in China: Black Magic, Black Beauty (small flower type or multi-headed) and Black Buck. Comparatively speaking, Black Buck is darker.

I once saw a black rose imported from the Netherlands a few years ago, and it was really black, but I don't know the name of the variety. Generally speaking, black roses in the usual sense are primary colors, not dyed. I have not seen any roses dyed black yet.

It's said to be black, but it's actually crimson. I made a bouquet of black magic variety roses wrapped in black packing material in exactly 07 years. Contrast this crimson with black.

There's this breed, and there's some that gets dyed. For profiteering.
