Geranium is widely cultivated in the world. Young plants are succulent herbs, while old plants are semi-lignified. Mainly used for sowing and cutting propagation.

Seeding and propagation are generally carried out in spring and autumn, and the optimum temperature for germination is 20-25℃. Geranium seeds are small and the planting depth should not be too deep. If carefully maintained, it will germinate in about 2-5 days, and if planted in autumn, it will bloom in the next summer.

Cutting propagation method of geranium

Geranium enters the dormant period from June to July every year. You can cut it at any time except these two months, but it is best to cut it in spring and autumn. Cuttings tend to turn black and rot in summer, and the temperature is very low in winter, so they will not take root.

Pelargonium hortorum will bloom in June if it is cut in 65438+ 10, and in February-March of the following year if it is cut in 65438+ 10. The specific cutting method of geranium is as follows:

1. Select robust geranium branches growing at the top, with the length of about10cm, put them in a well-ventilated environment, let the incision dry, insert them into a sand bed after filming, or insert them into a mixed matrix of perlite and peat, and keep them in a semi-shady place, with the temperature generally kept between 13 and 18. 56636.88868686666

2. Soaking the branches of Pelargonium graveolens with 0.0 1% indole acetic acid solution can improve the survival rate and rooting rate of cuttings. When the roots are 3-4 cm long, they can be transplanted.

Matters needing attention in cutting geranium

Geranium likes warm and is afraid of cold, so it is best to take warm measures in winter and move indoors for maintenance. It can be placed on the sunny windowsill to fully receive the light. When the light intensity is high in summer, shading should be done well.
