How often is it best to repot a Phalaenopsis, and should a newly bought one be repotted?

As we all know, most flower lovers who grow Phalaenopsis are appearance-driven; most of them love it for its flower posture and the wide variety of colors, and after blooming the flowers are as lively as butterflies, with petals that feel slightly waxy to the touch. In terms of varieties, some are small forms with flowers about 5 cm across, so the potted plant does not take up much space, while others are large forms with flowers about 15 cm across, and placed in the living room as a potted plant they look grand.

For beginners, if they want their Phalaenopsis to grow strong in everyday care, what should they do? Although many people have a rough understanding of care knowledge and know the principles of light, ventilation and watering, they still fail to grow it well. In fact, the mistake most flower lovers make starts from the moment they bring it home, because when bought from a greenhouse, the pot it comes with is usually very "ugly", so the flower lover cannot wait to change it to a pretty pot. However, doing so is completely wrong, because this fussing will make the Phalaenopsis simply go on strike.

If you want to grow Phalaenopsis well, the first condition is that it must live well, because this benefits its subsequent growth. When buying it, some people think that giving the Phalaenopsis a larger pot will give it more room to grow; this idea is not wrong in itself, but repotting also has disadvantages, namely that it easily injures its slender roots, and once injured they cannot be recovered. The second disadvantage is that, because Phalaenopsis roots like to grow in a medium that is well ventilated, drains well and is rich in organic matter, if the flower lover changes it to ordinary soil, that is equivalent to killing them (the medium is generally recommended to be sphagnum moss, bark, etc.). Even if the medium is not changed wrongly and the roots are not injured, because the home environment is not as stable as the original grower's greenhouse, it will also easily fail to bloom afterward.

So, when can it be repotted? Although repotting less often is good for Phalaenopsis, it does not mean never repotting. When you find that its roots have filled the entire pot, or the original medium has aged and rotted, then you can consider repotting. When repotting, you must be careful and try to keep the original root system intact; do not injure the roots. In addition, the repotting interval is generally once every 1 to 2 years, or even longer.
