coconutnucifera How to save Coconut Nucifera at home in Poland?

[Ilovepalm]

I need your advice. On Saturday, I will receive a Cocos Nucifera from someone, which does not grow well in this person, because it is too dark in the apartment and there is no adequate air humidity there. I would like to provide the palm with the best possible conditions. All I know is that the palm was purchased by this person 4 months ago. Over a week ago, it was transplanted. The flowerpot has no drain, although it has expanded clay at the bottom. The leaves from the purchase in the store were said to be torn and brown at the tips. But apparently one leaf this palm developed. My questions are:
1. How to secure a palm tree for transport by car (I live in Poland, zone 6 USDA, currently I have ok minus 6 Celsius outside)
2. Should I replant it in my house to the correct substrate and to a flowerpot with a drain?
2. How much water a week?
3. I read, that this coconut palm is helped by sea sand and watering with sea salt. Is it true?

If it were me getting this coconut, I would try and fit it in the car the best I could. I'm not sure if there's a proper way to do it? I'd probably wrap it in something for the brief period it is outside to the car and get the car nice and warm but not extremely hot Just do your best to fit it, even if it means leaning on its side or something.

For watering, I would say you kind of have to eye the soil and, depending on the soil that you used and how fast it dries out, I water my coconut every 2 months indoors, but that could vary depending on the amount of soil you have or how big the pot is, but I'd definitely get a pot with drainage and I'd get a grow light, or if you have a bright window, I'd put it there immediately because those leaves are very tall and leggy for a coconut at that age. 

as for everything else I don't know a thing about salt use

I'd re-pot it into a pot with good drainage in a medium that is both very well draining and very water-retentive. They need an awful lot of water but in combination with plenty of oxygen around the roots. You could even try growing it hydroponically. They also need a high level of warmth and light. The fronds are very long and slender on that one probably due to lack of light. They are evolved to grow in full equatorial sun.

Certainly don't expose it to -6C for more than a minute or two or you will kill it for sure. You could wrap some bubble-wrap or similar around the stem if you need to very briefly expose it to arctic conditions. You don't want to expose the meristem to anything under around 10C to be on the safe side.

They're certainly very salt-tolerant, although I'm not sure if the presence of salt actively helps the coconut or simply hinders competition for nutrients, etc. from other plants. It shouldn't do any harm to try; it might also put off certain pests like fungus gnats.
