How to prune sunflowers

When to prune sunflowers

The best time to prune sunflowers is in spring. When the leaves grow to 8 to 10, pinch off the top of the main stem directly to reduce nutrient consumption and promote the growth of the main stem and side branches.

After pruning the sunflowers, place them in a cool environment to wait for the wound to heal. Prepare fertile sandy soil, use chopsticks to poke neat and even holes on the soil surface, insert the cut branches into the holes, and the part inserted into the soil should not exceed 2 cm. Water them after insertion and place them in a cool and ventilated environment. Keep the soil moist, and they will take root in about 2 weeks.

Sunflower pruning

It is important to prune the sunflower during the seedling stage, and also to prune and top its side branches after they grow up. The number of flowers will increase in the later stage. When the leaves are found to be growing too densely, they should be thinned out, otherwise a lot of nutrients will be consumed, affecting flowering. Also, be careful not to get the wounds wet. First keep them in a cool place, and then resume management after the wounds are dry.

Sunflower pruning tips

Sunflowers can be topped to control the growth of the main stem of the flower, provide sufficient nutrients to the side branches, and naturally increase the number of flowers, but topping must be done in spring to be beneficial to growth.

Sunflower pruning and flowering

When pruning sunflowers, you need to cut off the dense leaves and shorten the branches. This will help the sprouting of new branches. Pruning the side branches not only beautifies the bonsai shape, but also reduces the supply of nutrients to the mother plant and increases the amount of flowering. It has a strong repair ability and can quickly resume healthy growth and bloom more.

Sunflower pruning precautions

When pruning sunflowers, choose a sunny day and avoid rainy days, because the wounds will easily become infected if they get wet on rainy days, affecting recovery. After pruning on a sunny day, the wounds must also be disinfected.
