I freakin love succulents! One of the few plants my forgetful self can keep alive and thriving! I don't even have a watering schedule for them, I just water when I remember and know it's probably been at least a week? I have a friend that has a house full of plants and loves caring for them who came over last week and marveled at how good my succulents look. Told him the secret is neglect lol.
Week? Man. I have a large Jade and water the thing evey other month. Sometimes it goes even longer than that. It's happily starting it's spring bloom after coming out from under grow lights in my basement to sit in front of a north facing window. All our smaller succulents are on a monthly ish schedule, but that's not anything we rigorously watch/pay attention to. Weekly for a succulent seems too often, but if they're happy they're happy.
I don't usually water them weekly, I just won't water them if I think it's been less than a week. I'd say they probably get watered on average every 2 weeks or so, give or take a week. Sometimes I remember to water them because I'll notice one starting to get pruny and shriveling a bit. To be honest I have no idea how they're all alive, much less thriving. I feel like a terrible plant owner, but apparently succulents are just my speed. Every one of them is all bright and vibrant, despite my forgetfulness and neglect.
