You should re-pot your house plants regularly, as plants that have been kept in the same pot for a long time may become pot bound and start to show signs of limited new growth.
You can easily tell if your house plant has become pot bound as you may see the roots starting to grow out through the holes in the pot, or you may notice that the growth has become sluggish,
It also does not hurt to re-pot your plants on a more regular basis such as once per year, in order to give them fresh potting media and a slightly bigger pot, allowing your plants will thrive in their new environment.
Re-potting allows the roots room to grow and expand, bringing new vigour to your plant and ensuring healthy leaves and long lasting vibrant flowers. Water your house plant a few days before you re-pot, so that the roots are smooth and flexible and so won’t be prone to breaking or damage and you won’t stress the plant as much when you transplant it.
