How to propagate geraniums, propagation methods / cutting / sowing / tissue propagation of geraniums

Pelargonium is a very ornamental plant, in many of our gardens can see its shadow, flowering is also its most beautiful moment. Of course, if you want it to bloom beautiful flowers, it has a lot to do with the reproductive process. As for how geranium breeds and what geranium breeding methods are, there are detailed records below, let's take a look.

1. How to breed/cut/sow/tissue propagation of geranium

Geranium how to reproduce, in fact, can be roughly divided into three methods, respectively, cutting propagation, seeding propagation and tissue propagation. Among them, cuttage propagation is the most common, and the survival rate is also extremely high. As for how to operate the three methods, let's look down.

2. Reproductive methods of geranium

cutting propagation

1. cutting time

Cuttage is one of the most common methods of geranium propagation. Pelargonium and general plants are different, summer is its semi-dormant period, so this time is not suitable for cuttage, except summer, the rest of the events can be cuttage, of which spring and autumn two seasons to carry out is the best.

2. selective branch

Pelargonium in the selection of branches for cuttage when it is best to choose more robust branches, which will be conducive to its survival. Generally, we can select branches with three leaf nodes and cut them about 4mm away from the previous leaf node.

3. environment selection

In the cutting half a month after the completion of the best time is to put geranium in a place without direct sunlight, wait until its callus formed, you can move to a place with sufficient light, but also can not be placed for too long, to master a good degree.

4. watering method

As for the watering of geranium, you can choose to water more at the first time, and then water less at ordinary times. Generally, you can use a watering can to spray water, because if you often water too much flowers, it may cause the roots to rot, so we have to remember this.

seed reproduction

Sowing propagation and cuttage propagation selection time point is the same, preferably in the spring and autumn two several. The main thing to remember is to control the ambient temperature, generally at 20-25° is the most conducive to its growth. Geranium seeds are not very large, so do not cover the soil too deep, generally 2-5 days after the completion of sowing can germinate.

tissue reproduction

Tissue propagation is a rare method among the propagation methods of Pelargonium. MS medium is generally used, and then indoleacetic acid and agonists are added to make callus and adventitious buds in plants. This propagation method provides a new way for the breeding of improved varieties and the reproduction of new varieties of Pelargonium.

How to breed geranium, sowing, cutting propagation method

How to breed geraniums 1. Sowing and breeding methods

First of all, prepare geranium seeds and soil. When the weather is cool, you can sow them. It is recommended to dry the geranium seeds first, then sow the geranium seeds directly on the soil. When the seeds are sown, cover the surface of the seeds with a thin layer of soil. The general temperature is controlled at about 20℃. The geranium seeds can germinate in about 7~10 days.

After germinating, geranium seeds need to keep the soil slightly moist. When the seedlings grow to 5~7 cm, they can be planted in 10 cm flower pots and generally bloom in the spring of the following year.

2. Cutting propagation method

Geranium cutting time is generally better in spring and autumn, that is, in April-May or August-September

Pelargonium branches are generally consistent from flowering, flowering frequently, and no pests on the mother plant, the general mother plant on the top of the shoot and the following tender stems can be used as cuttings, of course, the top of the branch is better, and the selected branches are cut down, the cut branches are generally soaked with 100 mg/kg indolebutyric acid for 5 to 10 seconds, and then dried.

After the geranium branches are dried, the branches are cut into the sand bed matrix, and water is poured thoroughly, then covered with a small arch shed, and placed in a ventilated environment. If there is strong light, shade is needed, and the environmental temperature is maintained at 15~20℃. Generally, the geranium will take root 2-3 weeks after insertion. When the geranium roots are 3~4 cm long, transplanting can be considered.

Seed and cuttage propagation method of geranium

Geranium is now more common flower plants, in the West, geranium is a very good decorative window sill flowers, there are also many flower friends will geranium potted, when flowering smell fragrant. Friends who love geraniums must wonder how geraniums reproduce. Pelargonium commonly used sowing and cutting two methods of reproduction, Xiaobian for you to introduce in detail these two methods of geranium reproduction.

I. Sowing and breeding

The seeding medium was composed of peat soil, vermiculite and pearlite mixed at the ratio of 8∶1∶1. Before sowing, water the substrate thoroughly, and then sow the seeds evenly into the seedling tray, covered with vermiculite, the thickness is about 3 times the diameter of the seeds. Disinfect the seeding box with chlorothalonil, build an arch and cover it with plastic film. The temperature is 20℃ to 23℃, and the humidity is kept above 95%. A week or so when the budding is uniform, lift the plastic film. Due to the low nutrient content of seedling substrate, foliar fertilizer should be sprayed every 10 days, and compound fertilizer with relatively high phosphorus and potassium content can be selected. At the same time, keep indoor ventilation, pay attention to the occurrence of disease.

When the seedlings grow to 4 to 6 leaves and the cuttings take root, they can be transferred to a nutrient bowl or a flowerpot for cultivation. Basin soil with good water permeability of sandy loam is appropriate, at the same time apply appropriate amount of base fertilizer, according to bud growth can also be appropriate topdressing. Pelargonium spring and autumn fertilizer needs large, July and August into dormancy, can stop fertilization. In addition, geraniums grow vigorously and should be pruned every year to promote flowering fullness.

II. Cuttage culture

Select well-growing plants and cut off the top 5 to 7 cm with a knife. The incised angle was 45, the basal leaves were stripped, leaving 1 to 2 leaves at the top. For example, the top leaves can be cut off by 1 /3 to 1/2 to reduce water evaporation. Because geranium base is fleshy mostly, moisture is much, take down immediately cuttage is easy to rot, reason should put shady place, make it dry hind again cuttage. Substrate often use sand, sandy loam or pearlite, inserted before the substrate irrigation through water, and then inserted, watering the cuttings after close clearance with chlorothalonil disinfection. Cutting temperature 15℃ to 18℃, about a month can take root.
