During the growth of sunflower, whenever its seedling grows to about 5cm, it can be trimmed properly, and the top of the main stem is cut off, leaving 6 ~ 1 leaves, and it needs to be trimmed properly with a shaping comb. Before pruning, it needs to be disinfected, and after pruning, it needs to be sprayed with carbendazim solution, so as to make it grow better. Illustration of the four steps of sunflower topping

1. Seedlings topping

Sunflower grows very fast. Generally, when the sunflower is sown and propagated, it grows to about 5cm, so it can be properly trimmed at the top of the main stem, and it is only necessary to keep 6-1 leaves, which can make the seedling grow better and sprout more new buds.

2. Heading at the top

Every time a sunflower grows into a seedling, it is usually necessary to cut off the part that grows too long at the top of the sunflower, or trim it for 3 ~ 5 cm, and comb it at the densely grown place, so that the sunflower can reduce the consumption of soil nutrients and is beneficial to the germination of lateral buds.

3. Trimming comb scissors

Under normal circumstances, after each pruning, the sun flower needs a trimming comb to cut off all its useless branches. If pests, diseases, yellowing and other branches are found, they also need to be cut off, which will promote photosynthesis in the sun and make beautiful flowers bloom at flowering time.

4. Disinfection treatment

Sunflowers should be prepared with a special pair of scissors in sunny days and disinfected, and each plant should be sprayed with carbendazim after pruning, so as to avoid being harmed by diseases, pests and bacteria in the process of growth, and make it wither and die gradually.
