Yes. Over time, your plant’s leaves may accumulate dirt and water spots; this is even more apparent against the naturally glossy surface of the green princess’ leaves. This dirt build-up can actually affect your plant’s rate of photosynthesis, which it requires to feed itself. You should regularly wipe the plants leaves with a damp soft cloth or give it a full shower every now and then to remove any dust that has accumulated on the leaves. This will also help ensure you have a healthy, pest free plant.
