 When you first bring your plant home, do the following. Check the roots. If they're coming out of the drainage holes, repot her to a pot that is maximum one to two sizes bigger. For leafy plants, make sure to clean the leaves with horticultural soap and water. You can also add neem oil just to make sure. Place your plant in quarantine for a couple of weeks and observe her just to make sure that she's happy and healthy. After this, you can place her with the rest of your plants and we're done.
