Plants with thin leaves need daily watering and ones with thick leaves need watering 3-4 times a week. This will also depend on the season. Generally during the blooming period, plants love a lot of water. Try keeping the soil moist. During winters it is better to cut back on watering.
Keep the plants in a well drained soil with a drainage hole at the bottom. This will help to avoid over watering. Take care as to not leave stagnant water on top of the soil. Fertilise the plant once in 2-3 weeks during its blooming period. Do not fertilise it in winters.
