the rooting time of geranium cutting can be selected in March in spring or September in autumn, and these two time periods are more suitable for cutting. The temperature is very suitable, relatively mild and moderate, which can promote the survival of cutting. If properly managed after cutting, geranium will generally take root and survive within 15-2 days. How to judge whether geranium cuttings have taken root can use disposable transparent plastic cups as cutting containers, and you can directly determine whether geranium cuttings have taken root by observing the soil. When there are empty gaps and white tender roots in the soil, geranium has taken root. In order to make observation easier, the cuttings can be inserted near the edge of the cup when cutting. How long does geranium grow leaves? Geranium usually grows leaves about 15 to 2 days after cutting.
cutting rooting method of geranium 1. Cutting: First, prepare a piece of foam and make a small hole in the middle. Then, insert the selected geranium branches into the central hole and then into the water in the container. In doing so, the buoyancy of the foam is used to make the branches stand in the water.
2. Post-management: After the geranium is cut, it must be placed in a cool place. Be careful that the temperature is not too high, and don't see too strong light, so as to ensure humidity. After about a month, the branches can take root. After rooting, normal maintenance can be resumed, the temperature can be kept warm, and scattered light can be properly irradiated. In the meantime, attention should be paid to changing the water so as not to make the water quality too bad.
how to disinfect geranium cuttings? Apply a little carbendazim to the cut position to prevent infection, then dry the pruned branches in a ventilated and cool place for 2-3 days to form a film at the cut position. You can soak the cut of geranium branches with rooting agent for 1-2 minutes, and then soak the cut with carbendazim solution for 3 minutes. How long can geranium be cut in the sun? Before geranium officially takes root and grows new leaves, we don't need to let geranium be exposed to the sun, just put it in a cool and ventilated environment for maintenance. Geranium can bask in the sun after taking root. How long can geranium be fertilized when cutting? Never fertilize geranium before it takes root. You can water it with a very low concentration of rooting agent every other week or so to speed up rooting.
Pelargonium graveolens can be fertilized after rooting, and liquid fertilizer should be applied every 1-15 days during the growth period, and once every 7-1 days in spring and autumn in the vigorous period.
Pelargonium graveolens mainly uses nitrogen fertilizer before budding, and mainly uses phosphorus and potassium fertilizer after budding, and the appropriate concentration is .1% ~ .2%. When it is maintained indoors in winter, the temperature is high, and it will not stop growing basically, so it can be properly fertilized. In summer, the plants are in a semi-dormant state due to high temperature, so fertilization should be stopped. How often do you water geranium after cutting? Geranium root system is fleshy root, and branches are prone to rot, so during its rooting, the soil humidity should not be too high. We only need to water it when the basin soil is about to dry out and keep the soil slightly moist.
