Cultivation techniques

1. Moisture. The thousand-petal sunflower has a strong tolerance to drought. The water absorption rate of the seedlings from growth to flowering is relatively low, only one-fifth of that during the growing period.

2. Nutrients. Adult Thousand-petal sunflower plants are very lush and have very developed root systems. When planting, they should be buried deep in the ground to promote the development of their root systems and to prevent the plants from being blown down by strong winds. This kind of flower needs to be supplemented with sufficient fertilizer in order to grow and bloom. When planting the sunflower in a pot, you can apply enough base fertilizer when planting, and you should also apply top dressing in time during the cultivation process.

3. Soil quality. Thousand-petal sunflower has strong adaptability and is not demanding on soil quality, so it can be grown in ordinary soil. You can choose soil with more humus.

4. Pruning. The pruning mentioned here mainly refers to branching. During the disk formation period of the sunflower, branches may appear in the middle and upper ends of its stems. At this time, these branches need to be removed in time so that the disk of the main stem can accumulate sufficient nutrients, thereby ensuring that the fruits are round and healthy. Pruning work needs to be timely. In addition, excessive density should be avoided so as not to affect ventilation and light transmission. If the plant grows too tall, you can choose to trim off some of the old leaves after the flowers are pollinated.

5. Reproduction method. The propagation method of Thousand-petal sunflower is relatively simple, which is scattering propagation. It is sown directly in early April. The conditions at this time are more suitable, and its seedlings can grow quickly. The seedlings must be thinned out in time and transplanted to the fields or larger potted plants after a certain period of time.
