[geranium seed] how to plant geranium seed

Pelargonium alias hydrangea, stone red, geranium originated in southern Africa, is now widely cultivated all over the world. Next let's take a look at the cultivation of geraniums.

Geraniums are strong in nature, with few diseases and insect pests; they are also adaptable, and all kinds of soil can grow, but sandy loam soil rich in humus grows best; it likes sunshine, is warm, is slightly resistant to drought, is afraid of stagnant water, and is not resistant to hot summer and hot sun exposure. Plants stop growing in summer, leaves aging, showing a semi-dormant shape, at this time can be transferred to the outdoor ☆ forbidden ☆ shade, stop the application of liquid fertilizer, watering on time, the pot will be put down in rainy days to prevent stagnant water rotting roots.

When the summer passes through the sky in September, you can turn the basin and change the soil, first cut the branches short, leaving only about ten square meters at the base of each branch, so that the new buds can be replaced by new branches. The geranium should be watered moderately, the basin soil should not be too wet, and the basin soil should be semi-dry half a day after watering.

Geraniums are mainly propagated in spring and autumn, but those with greenhouse equipment can also be planted in winter. Generally speaking, spring cuttings can blossom between New year and Spring Festival, while autumn cuttings can blossom at the end of April. The cuttings use new and old branches, but the tender shoots at the end of the branches grow best. Cuttings choose about ten centimeters, retain two to three upper leaves, such as the old strip can also be without leaves, the incision will be slightly shaded dry, inserted in the clean sand. The sand should be kept slightly wet and not flooded. First place in the semi-shade to keep the leaves from wilting, and then gradually come into contact with the sun after three to five days. Generally, it takes root in about two weeks, and it can be put on the pot when the root is three to four meters long.

Planting conditions of geranium seeds

Soil selection: geranium is suitable to survive in sandy soil, and the soil bought in the flower market mixed with some sandy soil is more conducive to the growth of geranium.

Weather impact: the windy weather will blow the geranium, while the heavy rain will make the roots of the geranium soaked by Rain Water, causing the roots to breathe anoxia and fester.

How to plant geranium seeds

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.
