If a plant is maintained at the same size and in the same sized container, it should have its soil renewed annually. Remove no more than one half the root ball. Root pruning allows the plant to continue its growth but not outgrow its container. You may not be able to repot larger plants. Instead, the top few inches of soil should be removed and renewed.
Many people put their houseplants outside for the summer.
This provides ideal growing conditions for many of the tropical and subtropical plants. It is important to acclimatize the plant to the outside conditions by gradually increasing the intensity of light. Move the plant first to a shaded porch or under a large tree for two weeks. Then move the plant to a partially shaded area. Finally, move it into the sun, assuming it will tolerate full sun.
