If you have done a good job of matching the plant to the location and regulating the watering, the need for grooming will be minimal. The occasional yellow leaf should be removed, and long runners on hanging baskets pinched to encourage the plant to fill in. Resist major pruning - most indoor plants do not have enough light to support healthy regrowth. Having a sharp pair of scissors is a great way to shape up a plant with old leaves. By cutting off the brown tips you can make your indoor plants look brand new.
Containers Try to use a container that provides drainage.
If this is not feasible remember to watch the watering. If it has a saucer underneath, do not let water sit in the saucer. If the plant does not use the water by the next morning, discard the remains out of the saucer. If placing the plant on a patio, weight down the inside of the container with rocks or pebbles before planting. This will prevent the container from blowing over in the wind.
