With the cooler weather I don't think two weeks is a big deal (my potted cacti are lucky if they get biweekly water even in the heat of summer and they do fine).

If you have something particularly fussy you might isolate those and have the housesitter water once midway through the vacation time-probably not asking too much assuming you don't have lots of picky things (most cacti/succs aren't).

-O-

Hiya Zzini and all,

Enjoy your vacation! I agree with Orrin that you cacti and succulents will be totally fine. Like you suggested, I'd just give them a drink right before you leave. The adeniums might, just might, shed a few leaves, but they will be fine. I wouldn't worry at all.

I always triple check my automatic irrigation system before heading out of town, even when I have a house sitter, just to make sure everyone is getting the drinks I think they are, especially newer plants.

Let us know how it goes! Safe travels, Grant.
