I would say - it is on a way to the Episcia heaven. What is the name of your Episcia? The pic is so small - I cannot see the details. If it is a variegated one - it needs high humidity NOW. If it is a green leaved one - it probably has bad roots. For variegated one - remove the dead leaves - and create terrarium conditions - dome, fish tank... something. If it is a root rot - remove wilted leaves and investigate the stems. If there some life left in them - I would cut them off and reroot in some kind of a terrarium - probably on humid sphagnum moss - this is a safest way - sphagnum moss has antibacterial and antifungal properties, You need a handful - Orchid places usually carry it. Good luck I.

I think that depends on the Kohleria. I don't grow them much so they are mostly outside of my range of being able to to offer advice though I'm sure Irina may be able. I have one, Tropical Knight, and it gets fun sun in the morning for about 4 hours. It takes it just fine as long as it has plenty of moisture (wicked) and keeps the plant a lot more compact that I can under my artificial lights. But Tropical Knight also has dark, almost burgundy leaves and another Koleria with pale green leaves might burn easily. If yours is reaching and getting leggy at all, I'd /ease/ it into brighter light (so not to shock or burn it) and see how it adjusts. Pinching also helps keep it busy and thick rather than bolting.

the idea is to remove fully green stolons, not the leaves. Leave the leaves alone for now and observe how it develops. Since it has at least 1 patially varieagated leaf - the stem should carry the section chimera mutation. I.

i like the 'slow growing' part a lot :))). cleo is quite breathtaking, no doubt! i am a total sucker ;) for multi pink-cream-green variegation, so i buy up all caladiums in sight that can fit on my balcony :)...and i have Stromanthe and Crotons 'Petra' indoors and a few others and even found a dwarf Hibiscus cooperi with that sort of coloring too. They are a riot - but very hard to mix with other variegated foliage plants for grouped arrangements. your tank arrangement is very successful in that respect - drifts of smaller plants with quieter colors hold it together. I really love it! i was into quilts a-ah... a few decades ago ;)..so love playing with color. can't resist to boast about my balcony wards from last summer :)
