How often should you change Phalaenopsis orchid potting medium? I'll teach you how to grow a pot full of flowers

In the flower market, Phalaenopsis orchids can be said to be the favorite of many flower lovers, and they are also the best-selling flower all year round. However, growing Phalaenopsis well is not something everyone can easily achieve, because its roots have relatively high requirements for potting medium. If you accidentally use the wrong one, it may also cause various problems, so how do you choose the right potting medium for Phalaenopsis? How can you help it grow healthily and even achieve the effect of growing until it fills the pot? Let's take a look below.

Phalaenopsis potting medium

Phalaenopsis natively prefers soil that is breathable and has relatively high moisture retention, so when choosing, you can use pine bark, coconut coir, perlite, etc. The characteristics of these media are that they are well ventilated and can also maintain a certain humidity, so they can be considered the best growing companions for Phalaenopsis.

Service life of potting medium

After choosing the potting medium, it does not last forever, and replacement needs to be judged according to the root growth of the Phalaenopsis. Normally, to keep the roots from accumulating too much salt, it is recommended to replace the potting medium once every 1-2 years. When replacing it later, gently pull out the plant, use a makeup brush to remove old residue stuck to the roots, and then replant it in new potting medium.

Fertilizing to boost growth

In daily care, in addition to choosing good potting medium and replacing it regularly, you also need to fertilize in coordination. Only by doing this can you grow Phalaenopsis well. During the two growing seasons of spring and summer, we can use diluted liquid fertilizer or compound fertilizer for watering, so that it has sufficient nutrient support. At the same time, potassium dihydrogen phosphate can also be used as fertilizer, which can promote flower bud differentiation and flowering. When using fertilizer, watering should follow the principle of "light fertilizer, frequent application". Do not develop the bad habit of using too high a concentration or fertilizing too frequently, otherwise it will cause root burn.

Watering and ventilation are indispensable

In daily care, we also need to pay attention to watering and ventilation. Although this seems simple, not everyone can do it well. When watering, be careful not to water too much or too little, and always keep the potting medium in a moist state, while also avoiding standing water. After watering, it should also be placed in a well-ventilated place. Doing this can reduce the occurrence of pests and diseases.
