A bay tree makes a very useful houseplant. Add a leaf or two to a pot of beans or stew, and you fill the house with a wonderful fragrance while making the food taste better. My bay tree has been living in a pot for over 30 yr. I repot it every few years, and it is now up to about a 3 gal pot. It goes outdoors into partial shade after frost and stays out until it gets cold in the fall. On a few occasions, I let it get too dry, and it lost almost all its leaves. But new ones grew back after it was outside and getting all the water it wanted. The only issue is scale, a tiny insect that forms a waxy shell over itself and secretes honeydew. If you let it get out of hand, the floor under the plant gets sticky. My solution is to wash each leaf with a rag dipped in water with a drop of dish soap and a drop of cooking oil. This happens once a year in late fall/early winter. For maintenance, I scout for sticky spots on leaves and scrape off the scale with a fingernail. Washing every leaf is great motivation to use lots of leaves in cooking so there are not so many leaves to wash.
I used to have a sunroom full of houseplants. I felt like a plant-slave maintaining all of them. Now I just have a few that tolerate getting too dry occasionally. My 40 year old weeping figs (Ficus benjamina) add lovely greenery to the house in the winter and also clean the air of chemicals. They do well in indirect light but not so well in a sunny window. They also tolerate a lot of neglect, like not being re-potted or fed regularly. If they get too dry, they will drop leaves. Pruning keeps the size down and makes them bushier. They used to live outdoors under the shade of large trees in the summer where they would sometimes bloom but not produce fruit. Now I just set them outside when it is going to be warm and raining for a few days. That cleans the leaves.
When the soil surface looks dry, I stick a finger in the soil to see if the plant needs watering. I like Nancy Reading's idea "Another tip is to have a wooden stick in the compost. When you think about watering, pull it out and test whether it is damp or dry to judge whether the plant really does need a drink or not." Popsicle sticks could work really well.
