Some netizens asked for help: Can the beheading and pruning of black pine be carried out in spring? When will the black pine be pruned? Well, I'm confused when I see this topic. Do you want to cut off the head of the black pine? This is the first time I've heard of it. If I'm not mistaken, I think I heard wrong.
It is difficult for black pine to rejuvenate after beheading. It may not take root for several years, and the longer it is, the weaker it will be. When I was studying black pine bonsai, I had the same idea of beheading as netizens. I want to transform the pagoda-shaped black pine into a cliff-shaped one. In practice, my master scolded me once: I still study botany, and I don't know the growth mode and the proportion of roots and leaves of black pine.
Of course, this is also a matter of experience. Therefore, when cultivating black pine bonsai, except when cultivating embryos, there is no need to behead later, because it is really difficult to rejuvenate. The main pruning methods for the later maintenance of black pine bonsai are picking needles, removing buds and pushing thimbles.
Can black pine bonsai be pruned in spring?
Black pine bonsai grows vigorously in spring. After the root system recovers its vitality, it quickly absorbs nutrients and water for the growth of black pine. At this time, it is also a period when black pine grows rapidly and flourishes. Therefore, pruning in spring is not recommended, except when changing pots or digging piles in spring. At this time, pruning is not recommended for normal maintenance of black pine bonsai.
In fact, it is easy to understand that after the embryo pile of black pine bonsai is fixed, the later maintenance is to raise roots and needles quickly, so that the roots are thick and luxuriant and there are many needles. But the root system has a great relationship with needles, and the root system affects the density and state of needles. In spring, the more needles, the more energy the photosynthesis of needles provides, the stronger the root system, the more luxuriant the needles and the more new buds.
If the needles are pruned in the lush growth period in spring, the root pressure and energy transfer are insufficient, which leads to the longer and thinner needles, which mainly affects the growth of new shoots. Therefore, we don't recommend pruning black pine bonsai in spring during normal maintenance. What we need to do is to apply more fertilizer and water to make it grow rapidly and luxuriantly.
When will the black pine bonsai be pruned? Now, after the management of water and fertilizer, the black pine has basically entered the lush period of summer, the new buds have aged and the needles are thick and green. This time is the best time for us to trim. We suggest pruning in June and July in summer. Pruned black pine enters the dog days, which not only reduces the waste of water and nutrition, but also can safely spend the summer and welcome the secondary growth in autumn.
