Okay, everyone... that's a lot to process, but thanks bunches for giving me REAL interaction lol! Books just haven't been cutting it for me.
There are a lot of drafts from the air conditioning all around the store. It's a small building, so there is only 1 side that has natural light... the northwestern side (not ideal, again). There are 2 installed grow lights (which, incidentally, are in all the wrong places and only a few of the houseplants receive light from them). We're hoping to re-situate plants and lights to get a better environment, but I'm a beginner working with less-than-ideal conditions. These succulents are definitely in tiny pots with drainage holes. They seem to dry out very quickly, but if I water them - even when they seem very dry - they still get root rot very easily. I just don't know how to judge dry from slightly moist, or dry from TOO dry. It's ridiculous!! I honestly think with no decent lighting, water isn't even the real problem.
I am going to take my camera to work tomorrow and try to show you what I'm working with (and hopefully even get some identification with the succulents. Our vendors NEVER tag them, so I'm at a huge loss when it comes to helping customers.)
This is a pretty open-ended problem until you can get a good scenario - my apologies for that! I'll do my best to get more solid info.
By the way, I'm in the middle of Nebraska and our weather fluctuates like crazy. Outdoors is incredibly humid most of the time at this time of year, but the inside of our store seems bone dry?? I don't know lol... This whole situation is working against me.
Hopefully this helps you help me more?
Thanks for all the welcomes, by the way
I really appreciate all this help! So much better than trying to do this by myself....
