Check the soil with your fingertips. Check the watering requirements of the plants with Google.
You can feel when soil is wet, moist, damp, barely damp, dry or desiccated.
In general the rule is to water generously, until a little drips out the drainage hole (which your plants should have) and then leave them alone. A heavy watering every three or four days is better than a sprinkle daily.
All plants need drainage or their roots will rot. You might want to repot and use a little layer of small stones at the bottom of the pot before you add soil and the plant.
(And please ditch the apostrophe. Plural of plants is plants.)
