guess it depends how many palms are in your clump and what size they are⦠you talking about seedlings? Once mature, they are super easy to tell apart, but as dinky seedlings it might be a bit more challenging. First of all, Dypsis lutescens have shinny green, smooth leaves, while Ravenea rivularis tend to have duller green and ridged leaves. Also Dypsis lutescens sucker like crazy, so as they age, there will always be new suckers. Raveneas do NOT sucker, so a clump will remain just as it is, only getting fatter and largerâ¦. eventually some of the palms may succumb to the competition. Also, Dypsis lutescens have a lot of yellow and white in their stems, while Raveneas have dull green and grey in theirs. Photo is of a clump in Dypsis lutescens in a nursery (aka 'Areca Palm')

I have never noticed a larger pot size allowed a palm go grow faster.. if anything, they usually grow slower in pots too large. But you should not be concerned about a Majesty growing to your ceiling height... rarely if ever happens no matter how well you care for it. They are not that fast a palm... they may grow leaves at a fairly good rate, but even in perfect climates in the ground it takes them many many years to grow that tall. In a pot, probably never. In fact, in indoor situation, most people's palms don't last even more than 2-5 years. But if you keep it outdoors as much as possible and water it well, you might beat the odds. These palms like a LOT of water (live in nature with roots or and sometimes stems in the water). Fertilizer needs of potted palms are WAY under a palm in the ground, so be VERY EASY on the fertilizer (maybe once a year at the most). If you can keep your palm alive long enough for it even for develop a trunk, you have done better than 99.9% of the others who try to make this an indoor palm. If you can keep it alive in a pot once it trunks, I suspect at best, 10-15 years before it is tall enough your ceiling will be a concern. Pot size would only have to get towards 25gal once it has a pretty good trunk on it. It could survive in a pot that size for a long time (I have seen people's fairly outdoor healthy palms in 15 gal pots that have 10' of trunk on them)

last pic looks fine .. is that after you removed all the old stuff??? i dont understand the first pic ... all palms shed the oldest frond or two come declination of the sun.. aka.. winter ... so that would be normal ... desert plants usually dont need misting .... and most peeps feel misting is useless anyway.. skip that ... water a plant when it needs it .. insert finger ... AND FIND OUT ... arbitrary schedules tend to cause problems ... because you are relying on a calendar.. and not the pot/media the plant is in ... im not sure it needs the direct light in the window.. if you have other plants that might need it ... off to the side might be good enough ... []though i dont know what you mean the corner the window is in .. maybe it is already off to the side????] lets try not to fix something that isnt broken.. aka ... love it to death ... ken

"just bought" means you don't know the care of the plant before that. Shipping damage and storage damage is completely normal, so don't panic too much. I'll repeat this below. :-) https://www.thesill.com/blogs/plants-101/how-to-care-for-majesty-palm-ravenea-rivularis For starters, follow any good care guide. That's just an example and if you prefer another one, that's great. https://houseplantresourcecenter.com/2020/10/how-to-treat-common-majesty-palm-problems/#:~:text=If%20the%20tips%20of%20your,your%20plant%20some%20extra%20humidity. Tipping can be caused by watering with fluoridated or chlorinated water (but any salt can cause tipping, including fertilizer), or in the case of the Majesty, specifically being too dry or in humidity that's too low. But given that it's new, just make sure you're giving it the right spot, right care, and a decent humidity and otherwise don't go into panic-changes with the environment. These could have happened at Home Depot, which sure didn't care for this plant properly.
