How to plant geranium seeds?

It can be carried out in spring and autumn, and indoor pot sowing in spring is better. The optimum temperature for germination is 20-25 ℃. Geranium seed is not large, sowing soil should not be deep, about 2-5 days to germinate. It will sow in autumn and blossom in the summer of the following year. After sowing and propagation, excellent intermediate varieties can be selected and bred.

Geranium likes warm winter and cool summer, so geranium seeds can be planted in spring and autumn, and indoor pot sowing in spring is better. The optimum temperature for germination is 20-25 ℃. Geranium seed is not large, sowing soil should not be deep, about 2-5 days to germinate. It will sow in autumn and blossom in the summer of the following year. After sowing and propagation, excellent intermediate varieties can be selected and bred.

Under suitable conditions, the geranium seeds begin to germinate on the day of sowing until the cotyledons unfold and the radicles protrude for about 1-3 days. Cover with coarse vermiculite to maintain humidity. No light is needed for germination. Providing 100-1000lux light will increase the germination rate and reduce the chance of overgrowth. Sowing 1-3 days, until the emergence of young roots, the medium remained saturated, 4-8 days, decreased to wet, after 9 days to keep the medium dry and wet alternately. The air humidity remained at 100% until the emergence of young roots, and then dropped to 40%.

After the development of cotyledons, in order to ensure the appropriate environmental conditions and adequate nutrient supply during the vegetative growth period, to ensure that the plant can successfully enter the induced flowering stage, generally planted in the south, the north should be pot-planted indoor overwintering.

When planting on the ground, we should choose places that are not easy to accumulate water, and the soil requires sandy loam with loose, fertile and good drainage. The pot culture soil was a mixture of rotten leaf soil, garden soil and sand. Put tiles at the bottom of the pot before planting to facilitate drainage. After being maintained for a period of time and then moved into a larger basin, an appropriate amount of rotten barnyard manure can be applied to the basin as base fertilizer, on which the culture soil should be loaded, and the root system should not be in direct contact with the base fertilizer.
