Yes, tridents have very vigours root systems and they really don't need all that extra moisture, keeping the soil a little on the drier side would be best. That's why you want very free draining soil with them, looser soil will help its roots expand.

Being where you are at, in zone 9-10, you could almost get away with repotting now. Fall repotting is not a customary practice where I'm at, where I'm at where it gets very cold, but where you are, some people might have relative success with it, so I guess maybe if someone from your climate zone could comment they'd be much more helpful
