When potted in fresh soil it gave good leaves. It grew under artificial lights and I only gave little water with now and then a dose of Reviver. That's a bottle with NPK 1-0-0 AND all micronutrients.

This was good for shocked or sick plants. Now I realised that I gave NPK 1-0-0. so no pk was in my fertilizer.

Can this be the reason for my problems? It's not in wet soil or rootbound.

Newer leaves are narrow, small and bright green. Older leaves get yellow /brown edges and later the whole leaf turns yellow. Also stunted growth. No new leaves are coming and the allready appeared leaves are not coming up very fast.

Checked the roots and the look healthy. Not tight in the pot.

Does the last picture with the shoots, show ca deficiency because of the wrinkled leaves and stunt growth?

Is that snow I see through the window of the second picture? Most Heliconias make bad houseplants during the northern winter because they require high humidity and warm roots.

That's residue from misting my plants.
I checked the roots and many were black. I removed all the death material and put it in fresh, dry soil.

Should I water it with root stimulating or let it resting?
The rhizome was trying to make new roots so hopefully it will start developing new shoots?

You still didn't tell me your temperate zone.

I live in the Netherlands.
But my plants. Have warming of pots and artificial lights 12 hours a day

Temp is 21 degrees celsius

What is the best root temperature at night? I will do everything to keep them alive. These plants are important to me.
When I die my ash must be spread on their soil. Their death will be unbearable.

The lamps are burning right now. Only thing is the root temp. What can and must i do. I have sprinklers for humidity. I keep the room warm
Only the roots because the pots are near a window during winter. In the past I had a heater cable with a thermostat which I had to put in the soil so it turned on when temp drops. As you can see I'm very fanatic with my heliconias. When they die i die with them

Hope you can help me with the root temperature.please in Celsius. I don't know in Fahrenheit.

Thank you

Just came back with a heating cable, thermostat with sensor.
What temp should I program for the soil?

Now the plant have new, dry soil, warmth me grow lamps and heating cable. I will stop watering so I hope I met Al the requirements. What temp should I program in the thermostat?

All heliconias grow well in Hawaii. This is the temperature:

Weather and temperature averages for Hawaii, USA (http://www.holiday-weather.com/hawaii/averages/)

But, high humidity is determined by microclimates under forest canopies. The average soil temperature is probably the same as the average sea temperature, about 27 deg. C.. Don't forget to water with warm water.
