Raising orchids, what is the most important management in autumn? Of course, it is the potting and changing the growing medium, after the spring and summer growth season, the nutrients contained in the growing medium are consumed a lot, if you can timely divide the seedlings and change the growing medium, you can make the orchid plant grow better in the coming year.
About how to turn the pot? How can I avoid grass retreat after turning pots and seedlings? How to use old and new growing mediums to make orchids more potted? In previous articles and videos, I have also talked about it many times, and I believe that Lan who reads my article has a certain understanding.
Orchids in the autumn in the process of turning pots and seedlings, Orchid You may find a problem, that is, after a spring and a summer, the root system of orchids is very vigorous, and even crowded with most of the orchid pots. In the crowded pots, the growing medium content is getting less and less. In the face of so many orchid roots, what should we do?
Some orchid friends may say that the root system proves that the orchid grows well, it does not need to be dealt with, right, is it not good to replant directly? In fact, if properly operated at this time, the orchid will grow better next year and the germinated new seedlings will be more vigorous.
Since the capacity of orchid pots is limited, this is incomparable with orchids in nature. We want to ensure that the environment required for the growth of orchids is provided to the maximum extent possible in a limited space. This is one reason for changing the growing medium, and another is the finishing of the root system.
Orchid root system growth rate is very fast, I once did a tracking experiment, the spring in March planting orchids, planting when the root system pruning is more fierce. Even such orchids, after a spring and a summer, under the premise that the growing medium and environment are suitable, the root system will be crowded with most of the pots.
If such an orchid root system is not sorted out, when the root system germinates a new crystal head next spring, the new root shoot will not have much room for development, which may cause the new root bud to directly suffocate. This is also one of the reasons why many orchid friends raise large pots of orchids and it is easy to raise zombie seedlings.
Well, now I know that after the orchids are turned over in the autumn, it is necessary to prune the old and sick seedlings, and it is also indispensable to trim the root system. But when we see the dense root system of orchids, how to prune them more effectively? The effective premise is that it can not affect the normal growth of orchids, but also leave a world of great achievements for the new roots next year.
In fact, it is not difficult to root orchids, just abide by these 3 principles:
<h1 class="pgc-h-arrow-right" data-track="10" > first, bad before good</h1>
This means that when orchids prune their roots, they first prune away the old, weak, sick, and residual roots, because these root systems have no meaning for the orchid plant. If left untied, they may deteriorate the small environment in the pot because of their decay.
<h1 class="pgc-h-arrow-right" data-track="15" > second, first weak and then strong</h1>
The weakness and strength of the langen are well recognized, and the strong roots are full and solid and elastic (the tip is relatively brittle). Weak roots are thin, thin, and shriveled. When pruning the roots, the weaker roots are cut off first, leaving only the strong roots. The orchid bacteria contained in the strong root are more abundant, which has a great role in promoting the pot after planting.
<h1 class="pgc-h-arrow-right" data-track="18" >3</h1>
The earlier mention is to thin the orchid root, so that after the operation, the orchid will only have a strong root left. But Lan You found another problem: the roots are too long, and some even roll in the pots, so what should I do? The answer, of course, is cut short. For these high-season, robust and particularly long roots, my principle is to measure them in pots.
Orchid planting pots generally have three drainage waist holes, and the middle hole is about half the height of the pot. When pruning the orchid root, you can use this as a reference, prune the orchid root to half the height of the pot, do not worry about it will affect the autumn and winter growth of the orchid. Because of the autumn and winter seasons, the source of nutrients for orchids is not much dependent on the root system.
<h1 class="pgc-h-arrow-right" data-track="23" > the treatment of orchid roots after pruning</h1>
Some orchid friends are accustomed to soaking the pruned orchid root system with fungicides, I personally do not recommend, so that the root system will absorb a large number of fungicides (unless it is touch sterilization without systemic effect), resulting in the root system rich in orchid bacteria being killed for no reason.
In fact, the breeding of bacteria in autumn is much less than in spring and summer, and the autumn climate is also relatively dry, and the wounds of orchid root system pruning only need to be dried in the semi-shade for half a day. In this way, the orchids in the orchid root will interact with the new growing medium quickly after planting, and promote the potting of newly planted orchids.
The above is only some of the views that the good farmer himself has experienced and seen, and the views may be one-sided and limited, only for Lan You's reference. If you have any other questions, please feel free to leave a comment in the comments section.
