Take begonias as an example, to share the leaf cuttings propagation skills, not only succulents can be propagated with leaf cuttings, other plants such as African viola, tiger pilan, money tree, watermelon pepper grass and other plants, can use the method of leaf cuttings to propagate new plants, but there are a few points to pay attention to, let's operate together.
The above is the use of leaf cuttings to propagate the potted begonias, the success rate of leaf cuttings and leaf cuttings is really quite high, whether it is the leaf cutting, or the whole leaf leaf cuttings propagation, there is a high success rate.
But be sure to pay attention to the choice of suitable seasons for cuttings, preferably in the spring and autumn, the temperature is stable between 18 and 22 degrees, there is a high humidity, a slight moist environment and soft scattered light.
1. Pick the right leaves
Schematic diagram of picking leaves
Before the leaf cuttings propagate, be sure to select the leaves, in the whole pot of begonias, to choose those strong and full, and relatively young leaves, do not choose too young new leaves, do not choose the bottom is too old leaves, otherwise can not be successful leaf cuttings.
2. Cut attention
When pruning the leaves of begonias, it is basically to cut off half of the petiole, it is recommended to use a blade, or a particularly sharp and flat knife, directly cut the petiole, cut obliquely, you can also cut flat, the key is to ensure that the pruning tool is sterile, you can spray some alcohol in advance to achieve the effect of disinfection.
3. Pay attention to soil configuration and hydroponics
Next, you need to prepare some suitable containers and soil, it is recommended to use peat, perlite and vermiculite, mixed in a 1:1:1 ratio, or peat and perlite, in a 1:1 ratio, or pure vermiculite.
Above are begonias propagated by hydroponic leaf cuttings
After the leaves are planted in water, the small buds grow are cultivated in the soil
In addition to the propagation of soil leaf cuttings, you can also choose hydroponic leaf cuttings propagation, but hydroponic leaf cuttings breeding generally uses the section with petioles, and after the root system grows at the petiole, it is necessary to pick it up and transplant it into the soil in time, otherwise its small buds will gradually rot in the water, or grow poorly.
Place in a box and place a basin of water on top, or spray water
After cutting off the leaves of these begonias, be sure to make leaf cuttings in time to ensure its activity.
We can see that there will be many leaf veins on the leaves of begonias, and its leaf veins can germinate roots, and where the roots germinate can form calluses, new small shoots can grow on callus, which is why begonias can reproduce with leaf cuttings.
4. Note the operation of leaf cuttings:
The small buds of the leaves have just germinated
When propagating leaf cuttings, you can prepare some crisper boxes, or some containers that can be covered with lids, mainly to maintain a high humidity environment.
After cutting the leaves of the begonia, the leaves can be cut into two or three pieces, each with more veins.
Leaf buds sprout gradually
After that, the cut leaves are inserted obliquely into the soil, the soil can be pre-watered and moistened, the bottom of the leaves is cut downwards, do not plant backwards, and then spray water into the pot soil, and the end with the petiole can be directly inserted obliquely into the pot soil. Maintain an air humidity of about 80% to 90% to avoid air dryness.
The leaf buds grow gradually
In addition, pay attention to placing it in a position where there is a soft scattering of light for 2 to 3 hours a day, do not let the lid remain stuffy, or leave some gaps in the lid (proper ventilation).
After the begonias propagated by leaf cuttings grow small buds, they should open the lid and slowly see the light, and the young shoots cannot accept strong light, and can only give a softer scattered light.
summary:
During the propagation of leaf cuttings, we must keep the potting soil slightly moist, do not let the potting soil be too wet, the potting soil can not accumulate water, do not use large water flushing when watering, generally it is spray-like water, as long as you operate a few times, more failures, you will find that the leaf cuttings propagate begonias are still quite simple.
