Sunflowers, also known as "never die," "pine leaf peony," etc., have small flowers but an amazing amount, with the ability to bloom dozens of flowers at once. They have single and double petals, bright and beautiful colors, low and full plant shapes, and lovely green leaves. Additionally, sunflowers have strong vitality and are easy to care for and plant, making them a favorite among many flower enthusiasts.
Sunflowers love heat and fear the cold. After the spring temperatures rise, sunflowers gradually regain vitality, start to germinate and grow rapidly. The first wave of flowers usually blooms in April to May, and they will continue to grow and bloom until November in autumn. After April, to care for sunflowers, just remember one sentence to easily raise them: "Plenty of water, plenty of fertilizer, plenty of sun, and move the scissors often."
1. Plenty of water
Actually, sunflowers are very drought-resistant plants. Both their stems and leaves are succulent, capable of storing a lot of water. Even if watered only occasionally, it's hard to kill sunflowers. However, not being able to kill them doesn't mean they are well cared for. Long-term drought will not kill sunflowers, but it will affect the differentiation of flower buds and reduce the number of flowers. Therefore, to ensure sunflowers bloom more, it's important to pay attention to补水.
The term "plenty of water" does not mean to water sunflowers frequently, as excessive watering can cause root rot and kill the plant. What is meant by "plenty of water" is to keep the soil moist. Water promptly when the soil surface turns white and dry. If the soil surface is not dry, there is no need to water.
2. Plenty of fertilizer
Compared with famous flowers that love heavy fertilization, like roses and hydrangeas, sunflowers are like the "little brother." However, in the world of succulents, sunflowers are definitely very fertilizer-loving varieties. When repotting in spring, remember to mix some organic fertilizer or slow-release fertilizer into the soil as a base fertilizer. When flower buds appear at the top of the branches, quickly use fertilizers like "Flower More No. 2," "Monopotassium Phosphate," or "Flowering Plant Nutrition Liquid" to promote flowering. Only when sunflowers absorb sufficient nutrients can they bloom large and beautiful flowers.

3. Plenty of sun
Just by looking at the name "sunflower," you can tell how much it loves the sun. Sunflowers need long hours of direct sunlight in any season. Even in the hot summer, there is no need to shade them, always place the sunflowers in the best light position.
The blooming rhythm of sunflowers is also closely related to sunlight. The flowers open and close with the rising and setting of the sun. The flowers gradually open after the sun rises in the morning, fully open at noon, and then gradually close as the sun sets in the afternoon. Therefore, sunflowers are also known as "noon flowers."
4. Prune often
Sunflowers are very pruning-tolerant plants. They grow quickly in spring, and often many sunflowers are planted in one pot. If not pruned properly and left to grow wild, the branches and leaves will block each other, causing a messy plant shape and reducing the number of flowers. In the early growth stage of young sunflower seedlings in spring, it's appropriate to pinch the top buds a couple of times: remove the top buds of the plant branches to encourage more lateral branching and increase the number of flowers. During regular maintenance, it's also necessary to prune sunflowers to keep the plant shape neat and well-ventilated.
