Ravenea Rivularis- cold tolerance in pot

[MarcusH]

At what temperature should I move my Majestic palm inside the house?  I already moved it inside because the temperature low is forecasted for 39°f tomorrow morning . Better be safe than sorry.

Left mine out in April when the last frost happened, which was around 28°F.  Seemed to have only damaged one frond moderately and tip burnt another frond.

Thank you for the quick response.  I guess I'll bring it inside once it gets to the low 30s then.

Many palms are quite tender at the roots and this has been tested (see Broschat et al., Ornamental Palm Horticulture). But I think this species is pretty tough, it can recover in areas of the Deep South with occasional strong freezes (e.g., New Orleans), and often recovers despite kill-out of leaves or the entire aerial crown. The soil and roots must get quite cold during these episodes. So I think at least you're probably fine leaving it out right down to freezing, perhaps a little lower, if under good cover, if the frosts/freezes are brief and not too cold, but perhaps just for safety's sake, take it in when they're predicting lows around 32F, and certainly I wouldn't trust it even under a deep eave next to the house, at your first hard freeze to the mid-20s. The only way you'll find out is to try it if you want to see its limits...at least these are extremely cheap and replaceable at the Big Box stores if you lose it during a test.
