help..

I have a couple questions...
1. I believe i have a Midnight lace sweet potato vine, it was doing great. Until i brought it in the house, after a week it started dying, all the leaves fell off and it looks just horrible. I don't know if maybe my cat eating it killed it or what. Will it come back, it's almost winter, so i'm not sure if it went dormant or just straight up died. I would like to bring it back it was beautiful, can it be stored over the winter?

2. My coleus plant was surviving well up until a couple of days ago. The leaves are turing a dark brown almost black and falling off the stems are even turning black.What could be causing this or better yet is there any hope for it and what should be done?

3. I heard putting egg shells in your plants helps them grow or fertilize them, is that true cause all i've seen them do is draw bugs i found what i believe to have been a fruit fly on my spider plant.

4. If any of these plants have a disease or infestation, what can i do to keep it away from my other plants or get rid of it before it kills everything. I'm not sure if any of them have a disease or anything i just want to be able to take the proper steps to help my struggling plants.

Thank you in advance..

Leaves adapted to outdoor light conditions are often unable to make the transition to indoor light and are shed. Often, humidity levels are a factor as well.

Your sweet potato is a tuber - like a yam. Lift the tuber and store it in a box in dry peat, choosing a cool dry spot for the winter. Replant in the early spring. If you store more than one, make sure they're not touching each other.

Did you just bring your Coleus in, too? There are several possible reasons for the ratty foliage, but more info is needed to give a narrowed down guess.

Egg shells are CaCO3, calcium carbonate, which is insoluble at pH levels normally associated with potted plants. If you whizzed them thoroughly in a blender so the pieces were extremely small, there may be a little Ca available, but that raises another issue. Adding Ca to soils w/o adding Mg (magnesium) can make it difficult for the plant to get enough Mg. Ca also raises the soils pH. It's probably better to avoid the eggshells. Unless you made your own soil, it was almost certainly pH adjusted with dolomitic lime, which just happens to supply both Ca and Mg. Since the Ca fraction of the lime is only about 1/125 as soluble as the Mg fraction, it's almost a certainty that the Mg would become deficient before the Ca, and that adding Ca w/o adding Mg would make that condition worse. To top it all off, most of this also hinges on the Ca/Mg content of your water.

To prevent disease spread, isolate and treat, preferably using Integrated Pest Management (IPM) practices.

Bottom line: Your plants are probably already getting all the Ca they need, and adding MORE than they need can be as bad as a deficiency (Liebig's Law of the Minimum).

Wow, thank you so much. The coleus and the midnight lace were brought in at the same time, approx. 1 month ago. I have a woodstove in my house if that helps anything, and they are in my s.facing window. However, we live in a heavily wooded area. The coleus is about 8in tall with 4 smaller stalks i believe they are called. I think it's dying.

The sweet potato still has vines on them, do i cut them off and store them or throw them away? I heard something about planting them, could something like that work?

Dark brown/black leaves that are falling off can be a sign that you're watering too much--you might try sticking your finger down a couple inches into the pot and see how wet it feels. There are probably a ton of other possibilities as well, so some pictures and/or more information would be helpful.
