Maintenance key: lightUnder the high temperatures in summer, many flower lovers think that sunflowers need shade to avoid being burned by the scorching sun. In fact, this is not the case. As the name suggests, sunflowers are a kind of plant that is not afraid of the sun. The more sun they are exposed to, the better they grow. So in the process of planting sunflowers, give it as much sunlight as you can! The sunflower needs at least 6 hours of sunshine. It grows well in sufficient sunshine, with many large and bright flowers. If there is less sunshine, it will grow slowly, grow too tall, and bloom few or even no flowers. Maintenance key: wateringThe sunflower looks fleshy, and some flower lovers may misunderstand that it does not like water. This idea is wrong. Sunflowers are drought-tolerant rather than drought-loving. If they are watered like succulents, the branches will turn yellow and dry, and the flowers will be sparse. It is drought-resistant but afraid of waterlogging. If water accumulates for a long time, the roots and stems will rot and eventually die. When watering sunflowers, just follow the principle of "water thoroughly when dry". Maintenance key: fertilizationFertilization is not necessary for sunflowers, but if it is applied, it can promote growth and flowering. Pengpeng uses chemical fertilizer 3-4 times a month. The fertilizer used is compound fertilizer and potassium dihydrogen phosphate, which are used alternately to promote both growth and flowering. Maintenance key: soilIt is said that sunflowers are immortal and are not picky about soil. They can survive in any soil, including yellow loam, humus soil, etc. If you want to plant sunflowers, just dig some soil and plant them. There is no need to prepare nutrient soil specially. Maintenance key: toppingTopping is the secret to growing good sunflowers. There is nothing interesting when only one or two flowers bloom. If you want to see more, you have to top them. Generally, when the sunflower grows to 10 cm in height, pinch off about 3 cm from the top of the sunflower. Then many branches will grow from the place where the topping was done. If you top the sunflower 3-4 times in this way, you can get a plump pot of sunflowers, and then you can let it bloom. Maintenance Key: ReproductionThe main ways to propagate sunflowers are sowing and cuttings, among which cuttings are generally used for propagation. Today I will share the cutting method of sunflowers. First, cut off about 10cm of sunflower branches. Because the branches contain a lot of water, in order to avoid rotting of the branches, you can dry them in the sun for half an hour. This is to play a role in sterilization. Insert the dried branches into the soil about 3cm. A 15cm pot can accommodate 8-10 branches. When you first take cuttings, you don't need to water them a lot, about once every three days. After they take root in half a month, you can water them once a day. Then you can do the topping and fertilization... Then you can see the beautiful sunflowers blooming~ |
