II. How Many Times Can a Dahlia Bloom in a Year?

According to Mr. Hu, the owner of a flower shop in the Changsha flower market, a well-cared-for dahlia can bloom about three times in a year, and its flowering period can also last more than half a year.

III. What Growing Methods Are There for the Dahlia?

The growing and propagation methods of the dahlia include root (plant) division, cuttings, seed propagation and so on, with the first two propagation methods generally being the main ones.

1. The dahlia is suitable for planting in loose, well-drained and fertile sandy soil. You can directly buy ready-made potting soil, or mix the materials yourself. Once prepared, dig a hole in the potting soil and plant the dahlia plant you prepared in advance.

2. The dahlia likes semi-shaded, cool places, so after planting it should be placed in a semi-shaded, cool spot. In addition, it can grow normally at temperatures of 5-35 degrees, so when temperatures are above or below this range, appropriate shading and warmth should be provided.

3. The dahlia's root system is rather delicate, so when watering and fertilizing, be careful not to pour directly onto the roots, and it is best to use diluted fertilizer. The amount of water for the dahlia is determined by the dryness and moisture of the potting soil. Generally, water more in summer (in the morning and evening) and less in winter.

4. During the growth of the dahlia, it is easily attacked by pests and diseases such as root knot disease, brown spot disease, powdery mildew, fruit borers and aphids, so it is best to do preventive work in advance. For branches and leaves showing disease, be sure to spray pesticide promptly, and branches and leaves with more serious conditions can be removed directly.

At present, there are more than 30,000 dahlia varieties, and such cultivars as Shouguang, Chaoying, Liren and Huazi are among the main cultivated varieties. Friends who like dahlias can also grow a pot at home; using it to decorate the interior and delight the mood is also quite nice.
