Propagation with a whole leaf with a petiole

This method is typical for Saintpaulias, Gloxinias, small-leaved peperomia and some types of begonias. To do this, take an adult healthy leaf, cut off at the base of the plant. The length of the petiole to be left will depend on where you will root it.

So, when rooting Saintpaulia in water, a petiole of about 3-4 cm is left at the leaf. And when rooting in the ground - no more than 1 cm. The tip of the petiole is cut strictly across with a sharp knife, dipped in a phytohormone solution (see phytohormones). The stalk is placed in a recess previously made in the soil, so that the underside of the leaf faces the wall of the pot. The leaf itself should not touch the soil, but rise above it. Then the pot is covered with a jar to increase air humidity and must be ventilated twice a day.

In general, you can root a leaf with a petiole in water, which is done more often, and in the ground. If you put a leaf in a glass of water, you can always take it out and see if the roots appear or not. If the leaf petiole does not want to give roots in any way, you can put it in a solution of the "Ukorenit" preparation - see phytohormones.

When a leaf with a petiole takes root in the ground (it can be a mixture of peat and sand in equal parts, or clean sand, or vermiculite), then you can find out whether roots have appeared only after some time: if you remove the jar and during the day and the next day the leaf does not wither - most likely, it has taken root. The fact is that in a dry room, if there are no nourishing roots, then the leaf evaporating moisture will not be able to replenish it in any way, and will begin to fade. After the leaf with the petiole takes root, it will begin to intensively build up the root mass, and only when it is sufficient will the aerial part grow. Therefore, sometimes flower growers ask the question: "the leaf is in the ground, does not wither and does not grow, what is wrong with it?" So, if the leaf is not under the bag or jar, then the growth of the shoots is not visible while the root system is growing.The rate of root growth depends on many factors, first of all, temperature, light and moisture uniformity. It must be warm, but not hot, optimally 24-26 ° C, not higher than 32 ° C, and light, but do not put the pot in a leaf in direct sunlight, otherwise the temperature under the jar or bag will rise greatly and slow down the development of the plant. The light should be bright and diffused. If necessary, you can supplement the lighting with fluorescent lamps so that the daylight hours are 12-14 hours.If necessary, you can supplement the lighting with fluorescent lamps so that the daylight hours are 12-14 hours.If necessary, you can supplement the lighting with fluorescent lamps so that the daylight hours are 12-14 hours.

Propagation as a whole leaf without petiole

This method is used for the reproduction of succulents (sedum, echiveria, bastard, zamiakulkas, etc.), Rex begonias. On the underside of the Rex begonia leaves, it is necessary to pre-cut all the thick veins, in succulent plants, fleshy and large leaves are pre-dried for two days. The soil is covered with wet sand, in which large leaves are immersed in the lower part, and small leaves are laid flat and slightly pressed.

Rex begonia leaves are large in size, therefore, you need to put the leaves on the bottom side of the surface of the sand and press them in several places with matches to the sand.

After rooting, the plants are planted in permanent pots when young rosettes or new shoots grow up. But some plants are difficult to replant, for example, stonecrop. When you transplant sedum Morgan, its fragile leaves instantly fall off under your fingers, and half of the shoots "go bald" before our eyes. In this case, it is necessary to plant in a permanent pot (without further transplanting), it is enough to put the leaf on the surface of the earth, maintain uniform humidity and good lighting. If the soil dries out too quickly, cover the bowl with leaves on the rooting with glass or film.

This is a common breeding method for Mason's begonias, royal begonias, sansevieria, streptocarpus, aloe and other plants, mainly succulents. Sansevieria leaves are cut into pieces up to 5 cm long, in begonia, a part of the leaf with a base up to 4 cm, and planted in moist warm sand or a very loose substrate from a mixture of leafy earth and peat.

To prevent the leaf from falling flat on the soil, a support stick is placed under it. At high temperatures (30-32 ° C), careful watering, and good lighting, pieces of leaves give roots and form a young plant. When propagating by part of a leaf, a higher temperature of the soil and air is allowed, because the evaporating surface of the plant is much smaller.

What is noteworthy, when dividing a leaf into parts and planting, it does not matter which side to lower the fragment of the leaf into the ground - where was the bottom or top, it does not matter, even if you plant a piece of leaf "upside down" it will still give roots. Here, the success of rooting cannot be called one hundred percent, often from the planted leaf fragments, only half or a third take root. Some rot, others dry out. From my own observations of the rooting of fragments of sansevieria leaves, I can see that the pieces of leaves planted in pure vermiculite took root better. I find an explanation only in the fact that vermiculite does not have organic elements, i.e. does not rot, absorbs water well and gives it away if necessary. No special maintenance is required, only occasionally spray the leaves and substrate. But later, with the growth of young leaves,transplanting into the ground is necessary, and here there is a danger of plant loss. The roots formed by cuttings in water and vermiculite have many fluffy root hairs, they are also called water roots. When planted in the ground, they dry out quickly, and the plant greatly inhibits growth, sometimes dying. Therefore, when planting in a pot, you need to make a hole in the ground and plant a leaf with roots there along with a part of vermiculite (without shaking the roots). After transplanting, shade the first days from the sun.in the ground, you need to make a hole and plant a leaf with roots there along with a part of vermiculite (without shaking the roots).
