Normal usually means water well weekly. But the size of the pot the
plant is in can have an effect on that so to check it I wouldn't let it dry out more than an inch down.
Even moisture is a pain for a beginner like me. I've been pretty much trial and erroring that one lol. I have a coleus that likes to remain moist but depending on weather it's in a growth phase or not the amount of water it wants changes radically. When it's
growing sometimes it wants water as much as every other day. But when it goes dormant it can go a week without water. So I'm not sure what to tell you.
Dry usually means the top two inches of the soil become dry. And that you should be using a fast draining soil like
cactus soil in the pot.
I wish I had more info or better info. But a lot depends on the type of
plant the type of soil the size of the
plant vs. the size of the pot. And weather the
plant is active or dormant. So there are bunches of consideration to get the watering just right.
