How to sow zinniasSuitable soilThe culture soil should be sandy and contain humus, be fertile, loose and have good drainage. Suitable temperatureEnsure that the suitable temperature for germination is 20℃-25℃. Make sure the ambient temperature for sowing is appropriate, not too high or too low. Temperatures that are too low can cause seedlings to grow into “little old seedlings”. Notes on sowing zinniaZinnias should not be planted densely, and one plant should be planted in each pot. Therefore, when sowing seeds, the number of seeds in each pot should not be too dense. Potted zinnias should be dwarf and large-flowered varieties, and can be sown in greenhouse pots in early February. Make sure the room temperature is stable, the light is sufficient, the air is well circulated, and there is enough water and nutrients. |
