to ATP It really depends where you're growing them, blondie. Temperature, how much sun, night temps, wind etc. can all play a part in how much water they need. Or if indoors, still the temperature, humidity, air movement and amount of light will decide how much to water. Even a ceiling fan can cause enough "wind" to dry out a plant much more quickly than you'd think.
How about posting a picture of the plants?
My Ricrac plant gets its leaves sprayed about every second day if it doesn't rain. At least once a week it gets a spray of weak soluble fertilizer. (just because my orchids are getting that too) If we have a really hot, dry run of days, I will pour a little water through the pot. But they do gather a lot of their moisture and nutrients through the leaves/stems so misting or spraying is my preferred method.
