Her yard is pretty shady, so I think that's the main problem. There may be some water issues, too. I'm giving them partial sunlight for a week or so, and will be washing the soil out with clean water, in case there is some kind of mineral build-up. Then I'll move them outside with the others, where they can bask in the full sun all day and devour lots of insects. Hopefully, by the end of the summer they'll be healthy again.
It may just be in my head, but I swear, they already look better, and it's only been about a week! I've been top watering them with distilled water to wash out any mineral accumulations, and they got a really hard rain today. I also moved them outside after only a few days, because it's been mostly cloudy anyway. I can see that some of the leaves are starting to yellow just a bit, and will probably die, but the new growth looks strong and healthy. You just gotta love how tough these little guys are!
It's just my email address and an expression of the oxymoron that I often am.
Call me Tim, if you prefer.
