Many friends who like to raise flowers have this problem:The branches pruned for the flowers were reluctant to throw away, so all kinds of flower pots were cut up, and after they were raised, they tried to give them away.
Cuttings are mostly carried out in spring, because after the temperature rises, the activity of the branches becomes larger, easy to take root, and better survive.
However, after entering the winter, as the temperature drops, many flowers have to enter the dormant period, and they need to be given a "winter pruning".
The answer is: yes, and there are 2 advantages.
Advantages The temperature in winter is relatively low, the bud points do not grow, but the wounds of the branches will healWhen the temperature is relatively high in spring, the wound tissue will grow, and when the temperature is right, the branches will take root first and then sprout.
In other seasons, when cuttings, because the temperature is relatively high, it will sprout first and then grow roots, which is easy to cause "false life", and this risk can be completely avoided in winter.
Pros The temperature is low in winter, and the activity of bacteria and fungi is very slowThere is a wound on the branch after pruning, and before it heals, the germs are not active, which can greatly reduce the probability of infection, but can improve the survival rate, and usher in a big explosion next year.
In this issue, we will share one"Universal cuttings**" suitable for winter, low temperature is good to live, next year's big explosion!
What are good cuttings? Personally, I thinkBranches that have a certain hardness, but are not highly lignified, are the most suitable. This type of shoot has a high degree of maturity and is relatively active.
toMonthly seasonFor example: when pruning the moon season and winter, the above branches are not long flowering, and the maturity of this branch is definitely enough, which can be used for cuttings, and the survival rate is relatively high.
The branches below the moon season are hard to the touch, and the color of the surface is relatively dull, and the maturity of this branch is high enough, but the activity is relatively poor, and it is not suitable for cuttings.
And some of the branches are newly grown, and they have not yet bloomed, and they are soft to the touch, and the color looks relatively fresh. This type of shoot is highly active, but it is not mature enough and is not suitable for cuttings.
AbsolutelyDifferent plants, because there are certain differencesIt is not necessary to choose the branches like the moon season, as long as you observe a lot, you will definitely be able to find the right cuttings.
On a cutting, there will be many knots, and some cuttings have short pitches and can retain 2 knots, such as the moon season; And some cuttings are long, you can keep 1 section, such as hydrangea, clematis, if you leave them also 2 nodes, the back will grow into a high neck, which is not conducive to the growth and strength of the plant, and the plant shape is not good-looking.
The way to prune cuttings is:Above the topmost node, cut off the top part flat; Below the lowest node, it is inclined 45 degrees, retaining 1-2 pairs of blades. If the leaves are relatively large, you can also prune off the 1 2 of the leaves, in order to reduce the evaporation of water, which is more conducive to rooting.
The advantage of retaining nodes is that cuttings take root, not only at the low end of the branches, but also at the position of the nodes below will grow new roots, the root system will grow longer, the probability of survival is higher, and the growth will be more vigorous; The above nodes are also easy to germinate new shoots in the later stage, and the natural plants will grow stronger and fuller.
Containers for cuttings, you can chooseSmall pots with bottom holes, or a disposable plastic water cup with a few holes at the bottom, which is permeable and breathable.
A tray for waterAfter cuttings, put the flower pot or water cup in the trayKeep the tray watery at all times
The medium of cuttings: For the medium of cuttings, it does not need to have many nutrients, after all, the branches take root, they can provide enough nutrients by themselves, and they do not need the support of the soil, the most important thing is that in factIt is best to have good water permeability and air permeability, and have a certain water retention capacity
I recommend using it the mostVermiculiteIt is a very good cutting material, and it is the most cuttings in many nurseries, which is clean, sterile and moisturizing.
Perlite and terracottaIt is also a very good substrate for cuttings, they are also loose, breathable, and have a certain water retention function, and they are particularly clean, which is very helpful to the survival rate of cuttings.
Use vermiculite, perlite or red jade clay to cut cuttingsWhen the root system grows and new leaves grow on the branches, it needs to be transplanted into ordinary nutrient soil to meet its growth needs
Some flower friends are troublesome, and the branches are directly cut into the nutrient soil, and the branches can be transplanted after rooting. Nutrient soil is used as a substrate for cuttings, and its disadvantage is that the water retention performance is too good, and it contains some humus, which is easy to lead to black rot of branches and increase the probability of failure of branch cuttings.
When cutting the branches, we need to put a small pot with 8 minutes full of substrate in a trayPour water into the pot and repeat several times until water leaks out of the tray.
Before cuttings,It is best to dry the branches in a cool and ventilated place, and see that the wound is slightly shriveled, and then go to cuttings。For cuttings, use a small stick to insert a hole about the same depth in the substrate, then put the branch in it, and press your fingers slightly around the perimeter of the branch, and this is done.
The next thing to do is to keep the tray watery all the time, place it in a warm, ventilated, shaded environment, and place it well.
During the winter season, the shoots hardly take root or sprout, and they are slowly healing the tissues. At this point, what we need to do is:Don't forget it, add water in time and wait for spring together.
When I introduced cuttings to you before, I would mention disinfection, rooting powder, and rooting agent.
Disinfection is to sanitize germs and bacteria in the branches; The purpose of using rooting powder and rooting agent is to increase the activity of the branch, so that it can grow roots early and quickly, and ensure a certain survival rate.
And in winter, our purpose is different. In winter, the germs are basically inactive, and the possibility of infection and black rot is very low, so as long as the incision is slightly dried and let it dry up slightly, it can be cut directly, and there is no need for disinfection.
In the same way, rooting agent and rooting powder are to promote rooting, in winter cuttings, wound tissue healing is the goal, rooting is not the goal, and there is no need to do more.
Written at the end of the article: It is suitable for winter "universal cuttings**" low temperature and good life, which is also a rare advantage. When the temperature rises in spring next year, the branches can take root quickly, free from the trouble of germs, and with good maintenance, it is easy to burst flowers.
