How to propagate Gaillardia

There are generally three ways to propagate Gaillardia, namely sowing and cuttings. The most commonly used and familiar method is the sowing method. Let’s study them separately.

Seed propagation

Seed propagation is often carried out in summer. The seeds and substrate must be processed before sowing. The substrate must be disinfected to kill pests and diseases. The seeds should be soaked in warm water for 3 to 10 hours, depending on the situation, as long as the seeds swell. Some seeds are too small to be sown by hand, so you can use tweezers to hold them and place them on the surface of the substrate. After all the seeds are sown, a layer of substrate should be attached, about one centimeter thick.

After sowing, you can choose to use a spray to lightly wet the substrate, so as to avoid the seeds being washed out due to excessive watering. Finally, cover with film. After sowing, when the seedlings emerge from the soil, the film should be removed and the seedlings should be exposed to light regularly. Be careful to avoid strong light exposure, for example, they can be exposed to light before nine o'clock.

Cutting propagation

Cutting propagation is also a relatively simple method of propagation. The material to be selected for cuttings is called cuttings. Cuttings are usually selected from the top shoots that grow well and are free of diseases and pests. The temperature during cuttings should be kept between 18℃ and 25℃. The cut ends for cuttings must be disinfected; if the temperature is too high, it can easily lead to infection of the cut ends. At the same time, if the climate is cold, you can cover it with a film to increase the ambient temperature. Shade is also necessary, blocking out more than half of the sunlight.

Things to note when breeding Gaillardia

After sowing and propagation, pay attention to remove the film and give appropriate light after the seedlings emerge from the soil. The light supply time should avoid the strong light period at noon, generally before 9 am to after 3 pm. During this period, they should be placed in a cool place. After the seedlings grow out one after another, appropriate thinning should be done, that is, pulling out the seedlings that are not growing well, leaving growth space and sufficient water and nutrients for the seedlings that are growing well.

The temperature must be controlled during cuttings. Too low a temperature is not conducive to the growth and survival of the cuttings after cuttings, while too high a temperature will cause the cut ends of the cuttings to be infected with bacteria. Appropriate shading should also be provided after cuttings, and the shading effect should be more than half. When the temperature is high, the number of watering should be increased.
