The planting method of sunflower exploding pot

The sunflower, also known as Scutellaria barbata, blossoms only when it meets the sun, and closes when there is no sun. Because of its strong reproductive ability, it is relatively easy to maintain, but it is not easy to want sunflowers to explode. Let's learn about the planting method of sunflowers.

I. cultivation of sunflowers

There are two main ways to plant sunflowers: cutting and sowing and propagation. The success rates of these two methods are relatively high, so there is nothing wrong with which method to choose for planting. The following mainly introduces the use of sowing and reproduction to cultivate sunflowers. For sunflowers, except that it is not suitable to reproduce in winter, it can be sowed and propagated in spring, summer and autumn. If you sow and reproduce in spring, it should be noted that the ambient temperature of the seed needs to be kept at 20-25 degrees before germination, so it may not reach this temperature in early spring, so seed germination should be carried out in the greenhouse. The best depth of the seed sown is about 3 cm from the soil surface, and it can germinate 10-15 days after the seed is sown. After the plant has grown a few true leaves, the first topdressing measure will be carried out in about 3 weeks. The seedlings planted in pots or open fields can be planted separately.

Second, the planting method of sunflower burst pot.

1. Sufficient light

The name of the plant shows how important light is to sunflowers. Light condition is the most important factor affecting the growth of sunflower, no matter in which growth period, its growth is inseparable with light; if cultivated in a darker place, it not only can not grow and blossom normally, it is also likely to lead to its death. Therefore, in the daily management, the sunflowers should be planted in the light, and if they encounter cloudy and rainy weather, they should be transferred to a place with bright light indoors to grow.

2. Fertile soil

One of the reasons why sunflowers are easy to develop is that there is no requirement for soil. Generally speaking, sandy soil commonly used in flowers can be selected. If the allocation of soil is more balanced and abundant, an appropriate amount of river sand and garden soil can be added to improve the drainage of soil. In addition, adding a sufficient amount of basal fertilizer is also a good choice, so that adequate nutrients can be given before the complete differentiation of the plant.

3. Appropriate watering

The need for water of sunflowers belongs to the common level among many plants, if watering every day, watering twice a week is a more appropriate choice, while when the summer temperature is high, it can be increased to three times a week, or even once every other day. It should be noted that the watering process should not be too hasty, slowly applied from around the plant at a uniform speed, so as to avoid the accumulation of water in the soil.

4. Defense against diseases and insect pests

Due to the good disease resistance of sunflower, it is rare to encounter the damage of diseases and insect pests in the process of plant culture. However, before sunflowers grow into true leaves and before flowering, it is best to take adequate protective measures and buy appropriate insecticides in the market for spraying, such as carbendazim or Huasheng solution, to ensure that the flowering of the plant can proceed smoothly.

For friends who cultivate flowers for a small number of times, sunflowers, which are easy to feed and do not need too much management, is a particularly good choice. I believe that as long as the above points are done, everyone will be able to cultivate satisfactory sunflowers.
