Roystonea regia seedling doesn't grow

[Than]

Sorry for double posting, I posted in the palms in pots forum by mistake. 

Anyone who has experience growing R. regias from seed, how fast do they grow? Mine sprouted about two months ago, unfurled the first leaf but nothing since. The leaf looks healthy. Is it too chilly for it to grow? Outdoors temperatures now fluctuate between 14C  - 21C or 57 - 70F. I put it indoors on a heat mat if the temperature drops below that. Humidity is at around 50-70%. It is in shade in a big pot and I water once a week roughly. Any thoughts?

It's the changing of the seasons. With shorter daylight hours available,and cooler temps,the palm has gone into resting mode and won't change much until daylight hours get longer,and temps are constantly in the 70 - 95 F range.

Keep your baby as warm as you can till April or May. Your task is to get it through the winter.

Thank you guys. I will probably keep it indoors full time from now on, on a heat mat and under grow lights.

They don’t do much for the first year. 1-2 leaves is normal. Keep it warm and don’t over water it. Once they put out pinnate leaves, they will increase their growth rate. The first pic is only about 1 year old and the second is 2 or 3 years old. These are completely neglected with no irrigation and in full Florida sun.

OK that's reassuring. I just need to be patient then.

I do not trust your soil mix. Just by looking at it...

50% potting soil and 50% seramis. Not good?

I do not like the look of it. Again it may be just a superficial impression.

John, are these volunteer seedlings or did you germinate them and plant them out as strap-leafers?  I have a few that are pinnate and wondering when it's safe to plant them.

@FuscaStrictly volunteers. The palms were removed February 2021. I still find volunteers all around the yard that have been transported by animals. If you are truly in 10a, I would not worry about planting them at any size. But at this point I would probably wait until spring.

The outdoor temperature is about the same here and my seedlings outside are still growing. More humid here than where you are.
