Tell me how to distinguish between annual and perennial sunflowers

1. First, from the perspective of blades.

Not necessarily absolutely, but most of the time it is like this, the perennial leaves are a little more elongated, the annual leaves are a little shorter, and then on the branches, the perennial ones will grow horizontally or creeping down, while the annual branches are more erect and grow upward. Perennial sunflower shoots generally grow on their creeping, but they can be topped to create a lush and beautiful shape.

2. Distinguish from the petals of the flowers.

Generally, when flowering, perennial sunflowers have many petals in each flower, and especially double-petaled sunflowers are generally perennial and not easy to produce seeds.

Single-petaled or with a small number of petals are easy to produce seeds, and annual ones are more numerous. In autumn and winter, when the temperature drops, the annual sunflower will gradually wither, while the perennial sometimes grows for a year or two, but it also needs warm temperatures. However, both types of sunflowers can be survived by cuttings.

The two kinds of sunflower are usually maintained, and the method is similar, you need to top it frequently, top, and let it see more sunlight, don't water too much, just water when the potting soil is slightly dry. And give more fertilizer. It blooms a lot and has bright colors.

If you want it to freeze in winter, it is okay in the Liangguang area, and there is no pressure in winter, but in places where the temperature is particularly low, as long as you use some methods, it can also be raised until the second year and continue to bloom and grow.

In autumn and winter, when the temperature drops, prune the branches first, it is best to prune more, so that nutrients and water can be consumed less quickly, leaving the main branches, and then placed indoors for maintenance, maintaining a certain temperature, at least more than 10 degrees, so that it will not freeze bad, and will continue to germinate new branches in the spring of the next year, bloom buds, and continue to bloom.

Raise annual sunflowers and perennial sunflowers, with 1 stroke, one tree for 2 years, flowering and old piles.

Perennial sunflowers are generally perennial sunflowers, which can bloom in all seasons if the temperature permits, and if the temperature is low in winter, the aboveground parts will wither, and will re-germinate the next spring, but do not produce seeds. The annual to the winter weather is cold even the roots withered, but the seeds, the second spring can be sown and reproduced, Huang Chonglou, Fan Chonglou for the perennial roots, generally from the leaves are not easy to distinguish, the flower double petals of the roots of the roots do not have stamens and pistils, single-petaled some have male pistils but do not inoculate seeds.

Sunflowers are perennial.

2. Spray water.

When cultivating sunflowers, if the watering is too little, it will lead to poor plant growth, so that the sunflowers will drop their leaves and flowers, and they need to be watered every other week to provide the water needed for the growth of the sunflowers, and they also need to spray water around the sunflowers when the weather is too hot to maintain the humidity of the plants.

3. Prune regularly.
