Sowing:

Thalia dealbata seeds can be sown from February to May and from July to September each year, but because conditions such as temperature and rainfall vary from place to place, the specific time that is most suitable for sowing also differs in different locations. To help the seeds germinate better and the plants grow vigorously, the sowing time should be decided according to local actual conditions.

How do you plant Thalia dealbata?

I. What kind of environment is suitable for Thalia dealbata

The quality of the soil directly affects the quality of Thalia dealbata seedling development. If the soil is very good and the growing environment is very good, then care by the gardener will be much easier. Thalia dealbata has few restrictions on soil type and can grow in sandy soil, loess, and slag soil, but soil with a high sand content generally has average sprouting. Thalia dealbata is afraid of water, so the terrain is required to be flat and convenient for drainage. When summer comes and the amount of water increases, the water must be able to drain away in time, otherwise local seedling death easily occurs. The key point of the terrain is that it should help drain away accumulated water. Average soil quality is enough, and sufficient sunlight is needed.

II. Land preparation

1. Plowing: Thalia dealbata responds quickly to nutrients. When the soil nutrients are sufficient, the flowers are beautiful and the plants are strong. However, the soil at some landscaping sites is on ground with average nutrients, so to get beautiful flowers, sufficient farmyard manure must be applied before sowing, with 3.5-7.5 tons of cow dung and horse manure spread per 660 sq m. After spreading the fertilizer, plow the land once and harrow it once. Only in this way will the soil and fertilizer be mixed evenly together with moisture, with no large clods of soil, making sowing easier and increasing emergence.

2. Making beds: To facilitate the maintenance and management work needed during the 1-year growing period of Thalia dealbata seedlings, such as watering, weeding, and topdressing, Changjing Landscape recommends making the land into standard beds 1.4 m wide and 12-22 m long, with the details decided according to the plot.

III. How do you plant Thalia dealbata

The seed particles of Thalia dealbata are generally medium in size, and the emergence rate is relatively strong. It is recommended to sow shallowly, with the soil covering no more than 5 cm deep. Broadcasting is generally used for planting. Choose conditions with little wind, mix the Thalia dealbata seeds into wet sand, and then broadcast them onto the soil. After sowing, you can cover the soil by raking manually or by machine. After covering with soil, water once, and emergence can increase in about 5-12 days.

IV. How do you care for Thalia dealbata

There are relatively few management and care tasks during the growing period of Thalia dealbata. It has no diseases, and its growth momentum is strong. The key work is mostly concentrated in the blooming period. Before the flowers open, apply 35 kg of chemical fertilizer per 660 sq m as topdressing. Applying fertilizer before flowering is to extend the blooming period and make the flowers and flower color more beautiful. After flowering, there is no need to fertilize. During the blooming period of Thalia dealbata, a lot of water is required. During this time, refer to weather conditions to decide whether watering is needed.
