Plants don't care for a heated air from a furnace blowing on them either so drafts may be an issue. Also look carefully for spider mites under the leaves as Crotons are very susceptable to mites in a dry warm winter situation. If the root ball looks OK, try misting a few times a day.

I have been trying to get up the nerve to trim my croton to keep it shorter and have found lots of good info on garden web. Just type in "croton" when you are in houseplant section and scroll down to ones that sound like they are about trimming. I found one at another site that says you can even trim it down to soil level and it will come back with several branches. Summing up, I guess you can make yours as short as you want. The branch or trunk you trim will probably not grow more but branches will come out of trunk giving you a bushier plant. This should be done when your plant is actively growing in spring or early summer. You can also propagate with your cutting from the top. Here is a nice youtube video about that https://www.youtube.com/watch?v=tAOwmUBFhzw

Crotons are not the easiest plant to grow indoors, but I have found that it can be done. My experience with crotons is that there are four big things you need to deal with to keep them going indoors: 1. High light - ideally it should be in front of a southern window. 2. Lots of humidity, but enough air movement so that the plant doesn't develop fungus problems. If you have a humidifer, you might want to try setting it up near the croton. I put my croton on the back of an aquarium to let it benefit from the humidity of the fish tank. 3. Frequent watering, but not so frequent that the soil stays constantly soggy and the roots rot. I agree with the person who said that this plant may be in too big of a pot and the soil looks too "heavy". A light, fast-draining soil mix will allow you to water frequently without rotting the roots, which is what crotons like. (I am actually growing my croton in a hydroculture set up so it has constant access to moisture but I wouldn't suggest converting a plant as fussy as a croton to hydroculture when it might be sickly) 4. Be vigilant about fighting spider mites. A lot of crotons come home from the store with spider mites and you need to be aggressive about killing them for the plant to grow well. Do you see any thin strands of spider webbing on your plant? That's often a sign of spider mites. If your plant has mites, we can tell you how to battle them. Where do you live? If it is warm enough, you could try putting the croton outdoors for the summer. They often do a lot better outside because of the light, warmth, and humidity (in humid areas at least). The only thing to worry about with putting it outside is that when you bring it back inside for winter there is a good chance it will have picked up spider mites while it was outside, so you'd need to plan on spraying it down with Neem or some other product to kill spider mites then.

I'm having the same problem with my croton plant (Bush on fire) drooping. The soil is usually damp unless I've just watered. The humidity is really dry like 18 - 22% with winter set in so I've placed a plastic over the croton. Also have a humidifier set up and 6 pails of water sitting around to help the humidity but to no avail. Plastic over the plant has helped the last of 3 croton plants (in same pot) to not droop till now. First the smallest, then the med. drooped and died during summer when a/c was on. The leaves are very colorful, shiny and strong and they stay that way even as they go down. I used miracle potting mix and wonder if this is the right soil? It sits in a south facing window in a mini greenhouse with extra plastic over the plant itself because the humidity is so low. I have containers of water under the plants in the greenhouse as well but with the greenhouse cover being quite loose at the bottom the air is very dry in there too. Also covered the bottom shelf with plastic to block some of the dry air and keep some circulation - not making a difference. What to do? any ideas? Then today as I was watering the plant, there were bugs, I think because of being closed in plastic - very damp around the plant. Will try the soap in water container first as that seems the least expensive at the moment. Thanks in advance.
