How to deal with sunflowers after they bloom
After sunflowers bloom, remove the spent flowers, trim the branches appropriately, thin the branches to reduce nutrient consumption, and water thoroughly every day. It is also necessary to fertilize the plants in time to supplement nutrients, mainly applying phosphorus fertilizer, applying thin and frequent fertilizers. After sunflowers bloom, increase the light for them appropriately, which can not only make the bloomed sunflowers more full but also extend the blooming period.
When do sunflowers bloom
Sunflowers can be planted in spring, summer, and autumn, but it's best to plant them in spring. In southern regions, you can choose to sow in mid-April. Sunflowers generally bloom from July to August each year, and the blooming period can last for about a month.
Methods for dealing with sunflowers after they bloom
After sunflowers bloom, cut off some branches that cannot bloom or are already withered. Then, water the plants thoroughly every day, apply thin and frequent fertilizers, and increase light appropriately. This can make the bloomed sunflowers more full and extend the blooming period, making the plants grow stronger.
1. Pruning
After sunflowers bloom, pruning is necessary to remove the spent flowers, then trim the branches appropriately, cut the branches shorter, thin the branches, and剪除 overgrown branches to reduce nutrient consumption and promote ventilation and light transmission, which is beneficial for maintaining their growth next year.
2. Watering
During the blooming period, sunflowers require more water. Although this is a drought-tolerant plant, it is best to water it once a day during the blooming period, making sure to water thoroughly each time. This can make the bloomed flowers more beautiful and prevent the occurrence of withered branches. Proper control can extend the blooming period.
3. Fertilizing
After blooming, the entire sunflower plant consumes a lot of nutrients and needs to be supplied with nutrients in time. Phosphorus fertilizer is mainly applied to the plant, with thin and frequent applications. This can make the bloomed flowers full and bright, and help balance the nutrients within the plant.
How to make sunflowers bloom more
If you want sunflowers to bloom more, the most important factor is to expose them to more sunlight, even under the intense summer sun. Then, ensure the maintenance temperature is above 18°C, which is very beneficial for sunflower growth and blooming.
Secondly, use loose and breathable soil for planting, water thoroughly when the soil surface turns white and dry, apply balanced nutrient fertilizer during the growing period, and switch to phosphorus-potassium fertilizer before blooming.
The methods introduced above for dealing with sunflowers after they bloom are for your reference.
