1、 Planting time

In general, March June in spring is the most suitable for planting zinnia. If planted within this time range, the seeds will germinate faster. It can also be carried out from August to October in autumn, but its germination rate is not as high as that in spring. Usually, when the temperature is above 15 ℃, you can plant safely

2、 Planting method

1. Prepare seeds: buy some high-quality seeds. It would be better if they were picked in the same year. Old seeds are not conducive to germination. Potassium permanganate should be used for disinfection before planting, but the soaking time should not be too long, just half an hour

2. Selection of soil: the selection of planting soil is very important. Whether the planting soil is loose and clean will directly affect seed germination. Rotten leaf soil, river sand, peat and some perlite can be prepared and used after disinfection

3. Planting method: put the sterilized seed in the soil, which can be sown on demand or sown. Finally, cover it with a layer of 1cm clean thin soil, and then give appropriate water to keep it moist
