Does the cutting of sunflower need fertilizer? How can the cutting of sunflower bloom more vigorously?

Sunflowers are very easy to grow, and poor soil is more favored by sunflowers. The branches of sunflowers can also be cut and grown into new plants. So do you need to fertilize sunflower cuttings? How can you make them more vigorous?

Does sunflower cutting need fertilizer?

For sunflowers that have survived from cuttings, it is generally sufficient to fertilize them once every 10 days. When fertilizing, it is better to apply phosphorus and potassium fertilizers, so that the sunflowers will soon bloom, and they will bloom more and have brighter colors.

When cutting sunflowers, you can add some well-rotted manure. As long as you don't put too much, it will be beneficial for the sunflowers to slowly grow and grow later. Fertilization in the later stage is to apply phosphorus and potassium fertilizers to promote the flowering of sunflowers and make the flowers more colorful.

However, it is not suitable to apply fertilizer when the cuttings are just taken or when the roots have just sprouted. Because the sunflower itself likes poor soil, and the current growth is not strong, if too much fertilizer is applied too early, it will cause root burn.

How to make the cuttings of sunflowers bloom more vigorously

Interpolation

If the sunflower cuttings are too sparse, with only a few scattered, it is recommended to supplement them in time to fill the gaps. The whole will become fuller and fuller, and the flowering will be good. When supplementing the cuttings, be careful not to cut the branches too short, as they are easily shaded by the first cuttings, resulting in poor growth in the later stage and poor ornamental value of the entire sunflower.

Topping

If the cuttings are not very sparse, they just look empty in some places. This does not necessarily require re-cutting, and it can be filled up by topping. Topping is when the sunflower grows to about 15 cm high, knock off the top of the main branch and let it separate the side buds. When the side buds grow to a certain height, knock off the top of the side buds and let more side buds grow. Do this several times, the sunflower can be divided into several branches, and the whole flowerpot looks good, with many flowers, and it does not feel sparse at all.

Which month is better to plant sunflowers?

The sowing of sunflowers is generally divided into spring sowing and autumn sowing. In spring, it can be sown in March and May, and in autumn, it can be sown in September and October. If it is sown in spring, it can be seen in June and July of the same year, but the flowering plant type may be relatively small, unless it is topped continuously before flowering, so that its plant type is fuller.

If sown in autumn, it will not bloom in the same year, but after growing in autumn and winter, it will grow very well in the warm spring, and there will be beautiful sunflowers in April.
