Frequency you should expect to water about every 4-5 days but don't follow a schedule, pay attention to the plant as far as the weight of the pot and ensure it has dried back enough since the last watering. When you water, work in slow motion. Use a drip irrigator if you can, or the bottle trick works good too where you poka a hole in a bottle with a thumb tack, sit the bottle on the soil and it'll drip in. Or if you're using a watering can with a shower head, pour in 4 ounce increments and wait 30 seconds in between pours. Keep at it until the medium is fully saturated and about 5-10% of what you added drips out the bottom. If you don't work slow, it'll lead to some potential problems down the road with the soil becoming internally "eroded" which leads to channeling, columning, shelving, salt pockets and potential displacement of important microbes. If you're going to water a plant, budget an hour of your time per plant. It's the greatest love you can show your plant, and she'll love you back for it.
