The regularity of watering will depend on factors such as the soil type and the weather. However the general rule is, "deep but infrequent". This means, try to penetrate the soil deeply when you do water but let the soil dry out a little before the next watering. Most plants will not be damaged by slight wilting. On the other hand, few plants will tolerate continually sodden roots. Besides, a healthier plant will be produced if it has to work for its water a little.
