DaisyI said:Growing spindly and flopping over are not a sign of underwatering, but rather, a sign of insufficient light. I suspect your new watering regimen (combined with poor light) has caused root rot.
Is that for both cactuses? They are both in bright south facing windows and I let them hang out outside for a few hours each day to get some west facing light as well, I can't see how they could get that much more light. The cactus baby that was growing spindly before is not the one pictured and it grew with absolutely no water (the cactus offshoot pictured in this post also grew as it is with mostly know water). Do you say it has root rot because of the skin? What are your suggestions? I just started watering them like that because someone who has a bunch of cactuses told me to. I'm gonna be really heart broken if I lose both cactuses. Please tell me how to remedy the situation.
