Yushu is compact, plump and green, beautiful and atmospheric, and can easily cultivate big and old piles. The plants are vigorous and simple, and the well-proportioned trees are especially ornamental.
Spring is the peak season for the growth of Yushu, and the favorite growth temperature is about 15 to 30 degrees.
As long as it reaches 15 degrees, Yushu begins to sprout and grow new branches.
Its budding ability is relatively strong, as long as it is a node, it can sprout one by one.
Therefore, in order to cultivate more valuable and valuable Yushu, we should always trim scissors and keep the beautiful plant shape.
If you cultivate a century-old tree, it can still be regarded as a family heirloom.
So how to prune Yushu in spring is a problem that many people collect.
Actually, the pruning of Yushu is relatively simple. According to these points, you can trim it into a particularly beautiful and fashionable old pile, and the shape is getting better and better, and it is no problem to save it for decades.
First, it depends on the time of pruning Yushu.
Pruning of Yushu must be in its growing season, because Yushu has strong germination ability. In spring, it grows everywhere, no matter old branches or new branches, small lateral buds will appear wherever there are knots.
If you don't prune it at this time, it will grow into a mass of branches and buds, which is very ugly and has no preservation value. Pruning Yushu in spring is very necessary and suitable.
If winter or summer dormancy pruning, Yushu will not grow after pruning, and the temperature is not suitable. If you cut off the branches, it is easy to be pulled back and the whole plant is easy to be hacked to death.
So as long as it rises to 15 degrees, it is time for Yushu to be pruned.
At this time, if the plant shape of Yushu is ugly, it doesn't matter even if it is cut bald. Soon, lateral buds will grow in the axils of leaves and grow into a beautiful Yushu.
Second, the necessary conditions for pruning Yushu.
When pruning Yushu, the soil in the pot must be kept dry, because the stem of Yushu is very thick, and its wound is relatively large after pruning. If it is just watered and trimmed, its juice is very rich, and a lot of juice will flow out of the wound, so if it flows out too much, it is easy to bleed.
Therefore, when pruning Yushu, it must be dried and maintained for about a week before pruning.
After pruning, its wound will shed a lot of juice, so it should be coated with carbendazim or plant ash to seal the wound or kill it.
Moreover, when pruning Yushu, try not to choose cloudy days to prevent the wound from being too wet and causing bacterial infection. It is best that the wound heals quickly in sunny days, without back pumping and rot.
When pruning Yushu, the blade should be disinfected as much as possible, or burned on the fire, because the wound of Yushu is very big, and if it causes bacterial infection, it is easy to cut off the whole plant type.
Third, the method of pruning Yushu.
1, slightly sheared
If the plant type of Yushu is beautiful, only a lot of small branches and buds grow in each leaf axil, or only a few branches grow longer and are crowded together, which affects the ventilation and the beautiful plant type.
At this time, you can choose to cut lightly and directly cut off the small shoots and branches that affect the appearance.
Because it has been initially formed, the crown above is full.
The buds growing at the bottom can be completely broken, leaving an independent trunk, which is also more conducive to ventilation. If individual branches grow on it, they can be cut off directly, and their internal branches can also be trimmed appropriately, otherwise the beauty of the whole plant will be affected.
Because the light of inner branches and transverse branches is blocked, they grow thin and weak, which will also affect the appearance and consume nutrients in the later stage. Just break them off.
Just fine-tune the plant type.
Step 2 cut again
If our Yushu grows white in winter because of insufficient light and the plants are loose, we should prune it again. If the distance between leaves of branches is very large, the whole plant will droop loosely, so it is of no value to raise, and it needs a support to grow upright.
You can cut it again in spring and it will grow soon. Don't worry about being hacked to death You can cut your head directly, for example, leave a suitable height from the position of the main branch, cut off all the tops, and cut off the whole canopy without leaving a leaf.
Only one trunk with a good shape is kept, and the rest are allowed to play freely and then grow freely.
Those loose branches can be cut off properly. If they are allowed to grow loosely, then this Yushu is also disabled.
After pruning, expose the bare stems to scattered light, and apply carbendazim or plant ash to the wound for disinfection. Don't water it yet, wait for its buds to grow and the wound to heal before watering it.
When its shoots grow to two or three centimeters long, they can be placed in sunny places, basking in the sun more and applying fertilizer.
Get more sunshine, make the leaves it grows more compact and thick, and keep the beautiful plant shape. This is the purpose of pruning.
Spring is the season for Yushu to grow, and it is also the season for adjusting plant type and pruning and cutting leaves. The pruned branches or leaves are directly thrown into the flowerpot, and a seedling will soon be regenerated.
So Xiaoyu saplings are worthless, and even many of them are thrown into the trash can.
But if you want to cultivate it into a very valuable old pile, you need to carve it carefully like a bonsai and cultivate a beautiful plant that can support a huge crown. If cultivated for decades or even hundreds of years, it will be a valuable heirloom.
