Large-flowered Geranium Propagation and Geranium Growing for a Full Pot: Cutting Methods and Timing
(1) Sowing propagation can be carried out in spring or autumn, with indoor pot sowing in spring being preferable. The suitable germination temperature is 20-25°C. Geranium seeds are not large, so after sowing the covering of soil should not be deep; they germinate in about 14-21 days. If sown in autumn, they can bloom the following summer. From seedlings grown by sowing propagation, excellent intermediate-type varieties can be selected.
(2) Cutting propagation can be carried out at any time except in June-July, when the plants are in a semi-dormant state. Spring and autumn are preferable. In summer's high temperatures, the cuttings tend to turn black and rot. The cuttings are 10 cm long, with the top portion being best, as it has vigorous growth and roots quickly. After cutting the cuttings, let the cut ends dry for several days; once a thin film has formed, insert them into a sand bed or a mixed substrate of expanded perlite and peat. Be careful not to damage the stem skin of the cuttings, otherwise the wounds rot easily. After insertion, place them in partial shade and keep the room temperature at 13-18°C. They root 14-21 days after insertion, and can be potted when the roots are 3-4 cm long. During the cutting process, soaking the base of the cuttings in a 0.01% indolebutyric acid solution for 2 s can increase the survival rate and rooting rate of the cuttings. Generally, cutting-grown plants bloom 6 months after cultivation, that is, cuttings taken in January bloom in June; cuttings taken in October bloom in February-March of the following year.
(3) Tissue culture propagation Geraniums can also be propagated by tissue culture. Using MS medium as the basic medium, add 0.001% indoleacetic acid and kinetin to induce the explants to produce callus and adventitious buds, and use 0.01% indoleacetic acid to promote rooting.
Geranium Growing Methods Geranium Propagation Methods
The geranium, a herbaceous flowering plant, is planted in dense clusters of blooms. The geranium's colors are very brilliant and it is very suitable as a potted decoration. The geranium's flowering period is very long, so those who like growing flowers can plant geraniums and have enough time to enjoy them. Below, let's share some geranium propagation methods.
I. Geranium Propagation Methods
Geranium propagation needs to be done by sowing, cuttings and other methods. Geraniums need a reasonable greenhouse environment, and tissue culture can be carried out in spring or autumn. In spring, the seeds can be placed in an environment at a temperature of around 20 degrees for growing, while in autumn, in June or July, the geranium seeds may enter a semi-dormant state, so at this time the seeds must first be treated before planting.
II. Geranium Watering Methods
Geraniums very much like a moist environment, so there should be no standing water, otherwise it will cause problems such as leggy growth of the geranium leaves and yellowing and dropping of the leaves. In summer, geraniums should be watered frequently, and each watering should mainly be a thorough soaking. In winter, watering should not be excessive; it is best to water only when the soil is dry.
III. Geranium Fertilizing Methods
During the growth process, geraniums are best given light fertilizer, which can promote the growth of flower buds, while adding fertilizers such as phosphorus and potassium to help the geranium grow. Geraniums begin to go dormant in summer, so fertilizing should be stopped.
Growing Methods for House Geranium How to Propagate House Geraniums at Home
House geranium is also called large-flowered geranium, butterfly pelargonium, etc. It is a perennial herbaceous plant of the genus Pelargonium in the family Geraniaceae, distributed in Africa as well as in Hubei and other places in mainland China. It has now been introduced and cultivated artificially, and its flowering period is usually July-August. Now let's take a look at the propagation methods of house geranium!
House Geranium Sowing Propagation
House geranium sowing propagation can be carried out in spring or autumn, with indoor pot sowing in spring being preferable. The suitable germination temperature is 20-25°C. Geranium seeds are not large, so after sowing the covering of soil should not be deep; they germinate in about 2-5 days. If sown in autumn, they can bloom the following summer. From seedlings grown by sowing propagation, excellent intermediate-type varieties can be selected.
House Geranium Cutting Propagation
House geranium cutting propagation can be carried out at any time except in June-July, when the plants are in a semi-dormant state; spring and autumn are preferable. In summer's high temperatures, the cuttings tend to turn black and rot. Choose cuttings 10 cm long, with the top portion being best, as it has vigorous growth and roots quickly. After cutting the cuttings, let the cut ends dry for several days; once a thin film has formed, insert them into a sand bed or a mixed substrate of expanded perlite and peat. Be careful not to damage the stem skin of the cuttings, otherwise the wounds rot easily. After insertion, place them in partial shade and keep the room temperature at 13-18°C. They root 14-21 days after insertion, and can be potted when the roots are 3-4 cm long. During the cutting process, soaking the base of the cuttings in a 0.01% indoleacetic acid solution for 2 seconds can increase the survival rate and rooting rate of the cuttings. Generally, cutting-grown plants bloom 6 months after cultivation, that is, cuttings taken in January bloom in June. Cuttings taken in October bloom in February-March of the following year.
House Geranium Tissue Culture
House geranium can also be propagated by tissue culture. Using MS medium as the basic medium, add 0.001% indoleacetic acid and kinetin to induce the explants to produce callus and adventitious buds, and use 0.01% indoleacetic acid to promote rooting. The tissue culture method provides a new way for the good-seed breeding and selection of new varieties of house geranium.
