Treatment method of pruning flower branches after flowering of sunflower 1
Many people don't know what to do after the sunflower blooms. In fact, this is an excellent time to prune the flower branches, because some non-flowering branches and some dead branches can be observed when flowering. At this time, the sunflower can be pruned in time after flowering, and these extra branches can be cut off, which is both beautiful and can concentrate nutrition.
2, water in time
Sunflowers in flowering need more water. Although it is a drought-tolerant plant, it should be watered once a day as far as possible during flowering, and it can be watered thoroughly every time. This will make the flowers more beautiful and there will be no dead branches. Good control can prolong its flowering period.
Step 3 supplement fertilizer
After the sunflower blooms, the whole plant consumes a lot of nutrients. If nutrients are not provided in time, flowers will wither and fall off. After flowering, phosphate fertilizer is mainly applied to plants, and the principle of applying thin fertilizer frequently is adhered to, so that the released flowers can be full and gorgeous, and the nutrition inside the plants can be more balanced.
Step 4 increase the light
Not only do sunflowers like sunshine during their growth, but they should also increase the light appropriately after flowering. The greater the photosynthesis, the brighter the stems and leaves of plants will be. Blooming flowers are not only full, but also can increase the amount of flowers appropriately. It is best to let them stay in a place where they can get weak astigmatism, which is beneficial to their growth.
