How to propagate geraniums to increase the survival rate
Geraniums (detailed introduction) are a fairly common variety among household flowers, and some flower lovers like to propagate geraniums themselves, so they pay close attention to the survival rate of geranium propagation. So what methods can actually improve the survival rate of geranium propagation? Let me give you a brief introduction.
Geranium (detailed introduction)
In order to control plant height and achieve the goal of large, brightly colored flowers, besides choosing dwarf geranium varieties, the application of growth regulators is very important. Two weeks after geraniums are planted in 12 cm or 15 cm pots, spray the leaves with 0.15% chlormequat or daminozide once a week for 2 sprays, with 14 to 18 hours of light per day; this can effectively control the height of geraniums and provide high-quality commercial potted flowers.
Geraniums are mainly propagated by cuttings. To improve the survival rate, the following points must be mastered:
1. Selection of cuttings. Choose branches that are solid inside and have a small cut surface as cuttings. The specific method is to first pinch off the growing tip of the mother plant, and after new side branches emerge, cut the branch from the base of the new side branch close to the mother branch.
2. Cutting time. Cuttings are generally taken in mid-September. If the cutting is not a newly grown side branch, the cut cutting must be left to dry for at least a whole day.
3. Temperature after cutting. It must be maintained at around 14°C, and all can take root after 2 weeks.
4. Watering. The potting soil must not be too wet; water when dry and let it dry between waterings.
Methods for high survival rate in geranium cuttings
Geranium cuttings are a relatively common propagation method for geranium enthusiasts. Compared with sowing, cuttings give more noticeable results. Many flower lovers do not handle geranium cuttings well. Look at the geranium cutting method below, and you will know what a high survival rate means.
Indicators for geranium cuttings:
1. The time is November, indoor temperature 19~21 degrees.
2. The cutting medium is perlite plus peat plus river sand; after mixing, scald the medium with boiling water.
3. Use the top shoots from pinching geraniums as the branches, and choose the cutting point at the leaf node.
4. Cut several small ventilation holes in the bottom and around the sides of the cutting cup. After the medium is scalded and cooled, use chopsticks to poke a hole in the middle and insert the cutting.
5. After cutting, place it in a foam box, pour 1 cm of cool boiled water into the foam box, and put it in a sunny place indoors. When you see less water in the box, add more.

How can geranium propagation improve the survival rate?
Soil, fertilizer and water management techniques for geraniums: pinch the growing tips when the geranium seedlings are 12 to 15 cm tall to encourage side branches. During the high heat of midsummer, strictly control watering; otherwise, if the potting soil of a semi-dormant geranium is too wet, the leaves often turn yellow and drop. During the stem and leaf growth period, fertilize once every half month, but do not apply too much nitrogen fertilizer. If the stems and leaves grow too much, stop fertilizing and appropriately remove some leaves, which is beneficial for flowering. During flower bud formation, add phosphorus fertilizer once every 2 weeks. Or use "Huiyou" 15-15-30 special fertilizer for potted flowers.
